memory game java gui

I'm trying to write a logic in memory game that when I click on cards and they are not a pair (different ID), program should swap them back after 1s. If they are same, then leave them as they are.
The problem is that when I first click and the card appears, after second clicking on another (different) card it doesn't appear and swap the first card after 1s. someone knows why the second card does not appear after clicking?
Btw when the pair is correct, everything works fine, here is my fragment of the code responsible for that logic in listener:
final int copy = i;
card2.addActionListener((e) -> {
card2.setIcon(new ImageIcon(icons[copy].getAbsolutePath()));
if(firstClick == null)
{
firstClick = (Card)e.getSource();
}
else
{
Card secondClick = (Card)e.getSource();
if(firstClick.getID() != secondClick.getID())
{
try
{
Thread.sleep(1000);
} catch (InterruptedException e1)
{
//e1.printStackTrace();
}
firstClick.setIcon(new ImageIcon(background.getAbsolutePath()));
secondClick.setIcon(new ImageIcon(background.getAbsolutePath()));
firstClick = null;
}
else
firstClick = null;
}
});

While method actionPerformed is executing, the GUI cannot react to mouse and keyboard events, so basically your code is "freezing" your GUI for one second. I believe that the class javax.swing.Timer is what you need and at first glance it looks like the duplicate question that MadProgrammer referred to may help you.

Java Method is skipping return statement

This java method is skipping over a return statement. I was wondering if anybody has encountered this and know of a solution. Whatever the bug is it's very subtle.
public GameState getNextGameState() {
if (player.getLives() > 0) {
if (!player.isAlive()) {
System.out.println("checkpoint 1");
player.setIsAlive(true);
return new PlayField(width, height, hiScores, player.setCoordinates(width / 2, height - 8),
stagePattern, stage);
}
System.out.println("checkpoint 2");
if(++stage > 29)
stage = 0;
return new PlayField(width, height, hiScores, player.setCoordinates(width / 2, height - 8), stage);
}
return new GameOver(Game.key, hiScores, player.getRank());
}
Here is a screenshot with console output to prove it:
Also, this bug only started happening when I put my gamestates in a stack structure. Here is the code I'm now using for the gamestate transition:
public void update() {
gsm.peek().update();
if(gsm.peek().finished)
if(gsm.peek().getNextGameState() == null)
gsm.pop();
else
gsm.push(gsm.pop().getNextGameState());
}
gsm declaration is:
public static Stack<GameState> gsm = new Stack<GameState>();
Hopefully someone has some insight. Thank you!

It is not the result of the same call.
You call twice the method here.
The first time it is not alive, the second is alive. So you have the both message in the output.
In a game, the update phase is called in a continuous way.
Just add a System.out.println at the beginning of the method (that is before the conditions) and you could have the confirmation :
public GameState getNextGameState() {
System.out.println("enter method");
...
}

Can you post more code? You are probably calling it twice and it is not skipping over the return. If you really think it is put a break point to assist you with debugging and watch the code run.

weird phenomenon about android Debugger (CloseableReference)

There I have a loop:
public void updateDrawee(View view) {
if (begin) {
begin = false;
for (int i = 0; i < 5; i++) {
CloseableReference<CloseableImage> reference = createBitmapRefer(i);
Log.i("reference", reference+"");
imgList.add(reference);
}Log.i("imgList", imgList.toString());Log.i("imgList.0", imgList.get(0)+"");
}
//...some code
}
and the method createBitmapRefer(int count) follow:
public CloseableReference<CloseableImage> createBitmapRefer(int count) {
ImagePipeline pipeline = Fresco.getImagePipeline();
int[] drawableIds = {R.drawable.alpha1, R.drawable.alpha2,
R.drawable.alpha3, R.drawable.alpha4, R.drawable.alpha5};
ImageRequest levelRequest
= ImageRequestBuilder.newBuilderWithResourceId(drawableIds[count])//++
.setProgressiveRenderingEnabled(true)//逐行加载
.build();
CloseableReference<CloseableImage> bmpReference = null;
DataSource<CloseableReference<CloseableImage>> dataSource
= pipeline.fetchImageFromBitmapCache(levelRequest, this);
try {
if (!dataSource.hasResult()) {
dataSource = pipeline.fetchDecodedImage(levelRequest, this);
}
//count %= 5;
Log.i("dataSource has result", dataSource.hasResult() +"");
Log.i("dataSource fail?", dataSource.hasFailed() + "");
bmpReference = dataSource.getResult();
Log.i("bmpRefer", bmpReference+"");
if (bmpReference != null) {
CloseableReference<CloseableImage> returnRef;
returnRef = bmpReference.clone();
return returnRef;
}else {
return null;
}
}finally {
dataSource.close();
CloseableReference.closeSafely(bmpReference);
}
}
when I debug, if i click step into and see the code step by step, it will return a CloseableReference just as I want, and the imgList(its a ArrayList) can get the element too.BUT if I step over the for loop, it return nothing!
Is there any different between keep looking at it or not???
the watches show elements in imgList, when index=1 and 4, I clicked step into.
and the logcat show what Log.i() print.
Or because I have not use this classCloseableReference in Standardized way?

Let me try to explain what happens here.
You are not using Fresco in the intended way. I will step back for a moment and strongly suggest that you use SimpleDraweView if you just need to display images. If however you really need the underlying bitmap, you can get it from the ImagePipeline in way similar to what you already doing, but with one key difference. Fetching images happens asynchronously. What that means is that you can't just do dataSource = pipeline.fetchDecodedImage(...) and then immediately dataSource.getResult. If the image was not found in the memory cache, getResult will just return null. What you need to do instead is to subscribe to the DataSource as explained in the Fresco documentation. I strongly suggest that you read those few chapters about ImagePipeline if you intend to use it directly. Otherwise you may cause your app to leak the memory or to crash because of rendering recycled bitmap.
What you see in debugger is exactly what I described above. The array of size 5 looks like this:
0 = null,
1 = CloseableReference#4908,
2 = null,
3 = null,
4 = CloseableReference#5231
The AndroidStudio UI just hides the null entries for brevity. You can turn this off if you don't like it by right-clicking there and opening options. The reason you get something for 1 and 4 is because the image has been found in the bitmap memory cache and was retrieved from it immediately. The reason you get null for 0, 2 and 3 is because the image has not been loaded yet. Fresco might need to download the image, and even if it is already downloaded and in the disk cache, it may need to decode the image. All of this takes some time and is not instantaneous. That's why you need to subscribe your callback and ImagePipeline will notify you when the image is ready.

I've created a simple game which a player plays against computer.
I've got an issue in the timing of the turns, the computer should be the first to make a move than the real player should make his move by clicking LeftChoice or RightChoice button.
Here's my problem at code:
public class GameForm extends javax.swing.JFrame {
/**
* Creates new form GameForm
*/
final int SIZE = 10;
int CurrentSize = 10;
int PC_SUM=0;
int HUMAN_SUM=0;
boolean PC_TURN = true;
int[] RandArr = new int[SIZE];
public GameForm() {
initComponents();
}
public void init(){
for(int i = 0 ; i<SIZE;i++){
RandArr[i] = (int)(Math.random()*100)+1;
}
jTextField3.setText("");
jTextField4.setText(Integer.toString(PC_SUM));
jTextField5.setText(Integer.toString(HUMAN_SUM));
}
public void HUMAN_updateLeft(){
HUMAN_SUM+=RandArr[0];
jTextField5.setText(Integer.toString(HUMAN_SUM));
jTextField1.setText(Arrays.toString(RandArr));
CurrentSize--;
int [] NewRand = new int[CurrentSize];
for(int i = 1 ; i<=CurrentSize;i++){
NewRand[i-1] = RandArr[i];
}
RandArr = NewRand;
jTextField2.setText(Arrays.toString(RandArr));
PC_TURN = true;
}
public void HUMAN_updateRight(){
HUMAN_SUM+=RandArr[CurrentSize-1];
jTextField5.setText(Integer.toString(HUMAN_SUM));
jTextField1.setText(Arrays.toString(RandArr));
CurrentSize--;
int [] NewRand = new int[CurrentSize];
for(int i = CurrentSize-1 ; i>=0;i--){
NewRand[i] = RandArr[i];
}
RandArr = NewRand;
jTextField2.setText(Arrays.toString(RandArr));
PC_TURN = true;
}
public static boolean WhoIsBigger(int[] arr){
int even=0,odd=0;
for(int i=0;i<arr.length;i+=2){
if(i%2==0){
even+=arr[i];
odd+=arr[i+1];
}
else{
odd+=arr[i];
even+=arr[i+1];
}
}
return even>odd;
}
public void PC_updateLeft(){
PC_SUM+=RandArr[0];
jTextField4.setText(Integer.toString(PC_SUM));
jTextField1.setText(Arrays.toString(RandArr));
CurrentSize--;
int [] NewRand = new int[CurrentSize];
for(int i = 1 ; i<=CurrentSize;i++){
NewRand[i-1] = RandArr[i];
}
RandArr = NewRand;
jTextField2.setText(Arrays.toString(RandArr));
}
public void PC_updateRight(){
PC_SUM+=RandArr[CurrentSize-1];
jTextField4.setText(Integer.toString(PC_SUM));
jTextField1.setText(Arrays.toString(RandArr));
CurrentSize--;
int [] NewRand = new int[CurrentSize];
for(int i = CurrentSize-1 ; i>=0;i--){
NewRand[i] = RandArr[i];
}
RandArr = NewRand;
jTextField2.setText(Arrays.toString(RandArr));
}
public void PC_TURN(){
if(WhoIsBigger(RandArr))
PC_updateLeft();
PC_updateRight();
}
public void FullGame(){
while(RandArr.length>0){
if(PC_TURN){
PC_TURN();
PC_TURN = false;
}
}
}
//start button listener
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
init();
jTextField2.setText(Arrays.toString(RandArr));
jTextField1.setText("-");
jButton1.setEnabled(false);
FullGame();
}
//left button listener
private void jButton2ActionPerformed(java.awt.event.ActionEvent evt) {
HUMAN_updateLeft();
}
//right button listener
private void jButton3ActionPerformed(java.awt.event.ActionEvent evt) {
HUMAN_updateRight();
}
How can i know that the real player has made his move so it'll change PC_TURN to True and the game will move on?

Firstly, you should follow Java Naming Conventions when it comes to naming your variables. As it stands, PC_TURN looks as though it is a constant, although it is not a constant since you are changing it's value. So a more appropriate name would be pcTurn.
You also seem to have a method called PC_TURN() which I am assuming is the method which causes the computer to take it's turn and do something. So it would be better if this was named something descriptive like takePCTurn(). Notice the use of camelCase throughout. Capital letters at the start of a name should be reserved for classes and interfaces, not variables or methods.
The same goes for your method name
public void FullGame()
should be written as
public void fullGame()
Keeping to coding conventions like this make it easier for others to read and understand your code and keep everything neat and tidy. It's a good habit to get into. :)
I don't know where your left and right buttons are being declared or what you have named them, but you will need to add an event listener to each button which causes something to happen when they are clicked. I also am unsure about the purpose of RandArr.length > 0. You really don't need a loop here since this is an application with a GUI, it is never going to close unless you explicitly tell it to (e.g by clicking the close button). So I will just give you a generic solution.
You basically want the players turn to trigger the computer to take it's turn until some game over condition is met.
Example:
//Assuming this is called when the Start button is clicked
public void fullGame() {
takePCTurn();
}
public void takePCTurn() {
//Do PC's turn logic
//You might want to check if the Computer Won the game here
}
class PlayerTurnListener implements ActionListener() {
public void actionPerformed(ActionEvent e) {
//Do Player's turn logic
//You might want to check if the Player Won the game here
takePCTurn();
}
}
//We can create an instance of our listener and add it to both buttons
PlayerTurnListener playerTurnListener = new PlayerTurnListener();
leftButton.addActionListener(playerTurnListener);
rightButton.addActionListener(playerTurnListener);
So the first thing that happens is fullGame() is called by your Start button which then calls takePCTurn(); causing the computer to take it's turn. Now nothing will happen until the player clicks the left or right button. When they do this, the PlayerTurnListener's actionPerformed() method is called and you can do some logic in there and then takePCTurn(); will be called once again.
Rinse and repeat until gameover.
Hope that helps :)

You should attach a clickListener onto the left and right buttons. Then when the user clicks one that event will be fired. You should change PC_TURN to true there and re-run the loop if needed.
Example:
JButton yourButton = new JButton("Your Button");
yourButton.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent e)
{
PC_TURN = true;
// extra code
}
});

If this is a Swing or other GUI then you will need to get rid of the while loop.
Remember that GUI programs are non-linear and are event-driven, and so rather than a restricting while loop which risks completely feezing your GUI, you would change the program's state depending on whose turn it is -- have a variable indicating whose turn it is -- and then change the behavior of the program based on the state.
If you need more specific help, then you're going to need to ask a much more complete question including one with enough code and explanation to allow us to understand your problem better (but not too much code).
Regarding the code you've posted:
Yes, definitely get rid of that while loop.
Your code is hard to understand, mainly because you're variable naming is poor. Rather than using variable names like jTextField1, use names that make logical sense, that make your code "self-debuggin", such as humanScoreField and computerScoreField, etc.
Also learn and follow standard Java naming practices including having all variables start with lower case letters, classes with upper case letters, use camelCase for all except for constants which are all upper-case.
Tell more about just what this code is supposed to be doing, what the buttons and the JTextfields represent, what behaviors you desire, etc...

Fest slows down while testing with swingx jxtreetable

I am not sure how to explain this. But I'll try.. Fest slows down to crawl while working with JXTreeTable of swingx. It doesn't slow down initially. It works fine for a while, but after a while when the same actions are repeated it slows down badly.
I have raised a bug for this in github. Please tell me if this is something that I am doing wrong instead. I am not able to reproduce the problem when I tried to create an SSCCE.
Anyway, here's a video of it slowing down.
http://screencast.com/t/liNttCw2In0w
At times 0.39s to 0.40 a set of operations are performed. These are done when there is one row in the JXTreeTable.
At time 0.49 to end of recording the same operation is repeated but there are now 3 rows in the table, it takes very long for the mouse to click.
I have attached a screenshot taken at the time when fest slows down, which attempts to explain it more
This is the code that does the work:
Step 1) Selecting a node from the tree is done as below:
JTreeFixture folioTreeFixture = importShareholders.panel("treePanel").tree("folioTree");
folioTreeFixture.separator("~");
folioTreeFixture.selectPath(new StringWrapper("Shareholders", true)+"~"+
(ShareType.isEquity(shareType) ? new StringWrapper("Equity Folios", true) : new StringWrapper("Preference Folios", true))+"~"+
new FolioTreeRep(folio.getName(),folioNo, shareType).toString());
Step 2) Searching and selecting a row from the JXTreeTable
int selectRow=-1;
JTableFixture table=importShareholders.table("historyTable");
for(int i=0;i<table.rowCount();i++){
String certificateNumber = table.cell(TableCell.row(i).column(ShareholderHistoryTable.columnIndex(ShareholderHistoryTable.CERT_NO))).value();
String remarks=table.cell(TableCell.row(i).column(ShareholderHistoryTable.columnIndex(ShareholderHistoryTable.REMARKS))).value();
if(StringUtils.isEmpty(remarks) && StringUtils.isNotEmpty(certificateNumber) && Integer.parseInt(certificateNumber)==certNo){
selectRow=i;
break;
}
}
if(selectRow==-1){
fail("Couldn't find certificate number to transfer");
}
Step 3) Showing the pop up menu and clicking the row
table.showPopupMenuAt(TableCell.row(selectRow).column(0)).menuItem("btnTransfer").click();
I am not sure why its slowing down. Please let me know if there is any more info I can help with. Would be grateful for some help in solving the problem
I have profiled the application and I dont find anything untoward happening. I dont have a lot of experience profiling applications. I would be grateful if someone could have a second look at this. I profiled it with yourkit and have uploaded the snapshot dump here:
https://www.dropbox.com/s/dh976v01q9c3sgj/ImportShareholderData.shouldTransferAndSplit-2013-06-14-shutdown.snapshot.zip
Any help will be greatly appreciated..
EDIT:
I think I forgot to mention the same thing works when I do it manually. It only slows down with fest. That leads me to believe that there is an issue with fest maybe?
Sorry about that.
EDIT 2:
As request by Marcin (sorry for the delay Marcin).. Here's the code when the first row is getting split
public List<Integer> splitRowEqually(ShareType shareType, String date, int folioNo, int certNo, int... certnos) throws NoSuchFieldException, TorqueException {
//select a tree node
selectFolioInTree(shareType, folioNo);
Pause.pause(new Condition("Wait until tab is created") {
#Override
public boolean test() {
return importShareholders.tabbedPane().tabTitles().length>0;
}
});
//select a row on the table to split
int row=selectRowWithCertNunber(certNo);
List<Integer> rowsIndexes=new ArrayList<Integer>();
JTableFixture table = importShareholders.table();
//show popup menu on that row and select split
table.showPopupMenuAt(row(row).column(columnIndex(TRANS_TYPE))).menuItem("btnSplit").click();
DialogFixture splitDialog=FinderUtilities.getDialogWithTitle("Split Share Certificate");
splitDialog.textBox("tfDateOfSplit").setText(date);
int noOfShares= Integer.parseInt(table.cell(row(row).column(columnIndex(NO_OF_SHARES))).value());
int distFrom= Integer.parseInt(table.cell(row(row).column(columnIndex(DIST_NO_FROM))).value());
int distTo= Integer.parseInt(table.cell(row(row).column(columnIndex(DIST_NO_TO))).value());
//split the row into the number of times decided by the certnos array
int noOfSharesInEachSplit=noOfShares/certnos.length;
for(int i=0;i<certnos.length;i++){
int distToInSplit = distFrom + noOfSharesInEachSplit-1;
enterSplitRowDetails(splitDialog, certnos[i], distFrom, distToInSplit<=distTo ? distToInSplit : distTo);
distFrom=distToInSplit+1;
rowsIndexes.add(row++);
}
splitDialog.button("btnSplit").click();
return rowsIndexes;
}
//selects a node from the left hand side tree
public void selectFolioInTree(final ShareType shareType,final int folioNo) throws TorqueException {
JTreeFixture folioTreeFixture = importShareholders.panel("treePanel").tree("folioTree");
folioTreeFixture.separator("~");
// I use these wrapper classes - StringWrapper and FolioTreeRep, so that I can get a html
// string for the tree node like <html><b>Shareholder</b></html>
String treePath = new StringWrapper("Shareholders", true) + "~" +
(ShareType.isEquity(shareType) ? new StringWrapper("Equity Folios", true) : new StringWrapper("Preference Folios", true)) + "~" +
new FolioTreeRep(mapOfFolioNames.get(folioNo), folioNo, shareType).toString();
folioTreeFixture.clickPath(treePath);
}
//search the table for a row that contains the cert no provided in the Certificate Number column.
private int selectRowWithCertNunber(int certNo) throws NoSuchFieldException {
int selectRow=-1;
JTableFixture table=importShareholders.table("historyTable");
for(int i=0;i<table.rowCount();i++){
String certificateNumber = table.cell(row(i).column(columnIndex(CERT_NO))).value();
String remarks=table.cell(row(i).column(columnIndex(REMARKS))).value();
if(StringUtils.isEmpty(remarks) && StringUtils.isNotEmpty(certificateNumber)
&& Integer.parseInt(certificateNumber)==certNo){
selectRow=i;
break;
}
}
if(selectRow==-1){
fail("Couldn't find certificate number to transfer");
}
return selectRow;
}
// enter details on the table in the SplitDialog
private void enterSplitRowDetails(DialogFixture splitDialog, int cert, int distFrom, int distTo) {
splitDialog.button("btnAdd").click();
int row = splitDialog.table().rowCount();
splitDialog.table().enterValue(row(row - 1).column(0), String.valueOf(cert));
splitDialog.table().enterValue(row(row - 1).column(1), String.valueOf(distFrom));
splitDialog.table().enterValue(row(row - 1).column(2), String.valueOf(distTo));
}

Emm... It is quite interesting question;
I suppose the question contains less really required details especially the robot integration and IO solutions details so I cannot just give you a proper answer...
Anyway, I'll try to analyze the problem in voice a little bit in my way...
First. According to your screenshot comments, I can notice that all "30s pauses or so" occur on some, as I can get it, stream reading process "select/search" (your app gets some data to output etc). So maybe it is much deeper than you think because it is probably thread problem;
I couldn't find the GuiQuery/GuiTask/GuiActionRunne classes usage in your code snippets so I may suggest the "synch problem" may take place in the mentioned case...
Second. OK... If it is still the thread problem I may suggest the robot and IO solutions are both in some ONE thread (the Main thread or something) because, according to your tips as "At times 0.39s to 0.40 a set of operations are performed. These are done when there is one row in the JXTreeTable." ... GUI is waiting for some process to be completed...
Third.
And again... According to this issue as
"It is recommended to turn on an automated check to verify that all
Swing components updates are done in Swing’s EDT (Event Dispatcher
Thread). For those unfamiliar with the EDT, it is responsible for
handling and updating all Swing widgets in a separate thread, causing
that the application never loses responsiveness to user gestures (just
in short, more about the EDT here). To do that, we add the following
hook to the test:"
import org.fest.swing.edt.FailOnThreadViolationRepaintManager;
import org.junit.BeforeClass;
...
#BeforeClass
public static void setUpOnce() {
FailOnThreadViolationRepaintManager.install();
}
Next step is to launch the frame or dialog. As JUnit runs in its own
thread, we must launch the frame or dialog through Fest, to ensure,
again, that EDT is properly used:
import org.fest.swing.edt.GuiActionRunner;
import org.fest.swing.edt.GuiQuery;
import org.fest.swing.fixture.FrameFixture;
import org.junit.Before;
...
private FrameFixture testFrame;
private AllTypesFrame frame;
...
#Before
public void setUp() {
frame = GuiActionRunner.execute(new GuiQuery<AllTypesFrame>() {
protected AllTypesFrame executeInEDT() {
return new AllTypesFrame();
}
});
testFrame = new FrameFixture(frame);
testFrame.show();
}
... makes me think it is maybe the "thread-problem" which is described in the First and Second tips...
so, as a conclusion, I can say that maybe you have to multi-thread your test a little more because it is obviously some kind of synch problem...
P.S.
#sethu, before you start your debugging I want to point a little...
I still suspect threads conflict is taking place here (see my previous tips) because, as I may notice, your code snippets are showing static expressions usage to invoke methods like Pause.pause(...) or FinderUtilities.getDialogWithTitle(...) etc I cannot see the whole project architecture so it is hard to analyze according the represented bits but it is pretty clear the "manual testing" goes fine because action listeners react in real time but fest testing does the annoying delays because it uses some "timer" to countdown until a click emulation occurs etc and of course it is a background process which needs a separate thread... Watch debugging carefully maybe somewhere in your code UI thread and fest thread do conflict (see static methods, thread.sleep etc) the points where fest thread could block (override) the UI's one... :S By the way what method Pause.pause(...) does?
P.P.S.

I do not know what are your robot settings but you can at least try to set idleTimeout and other timeouts for the robot you use. The default timeout is 10 sec (look in org.fest.swing.core.Settings). After I decrease it (first 1000ms, next 100ms) I noticed that robot works faster.
robot().settings().idleTimeout(YOUR_TIMEOUT)
Here is my test setup and one test method. Hope is clear.
Here you have my before/after
private static int testMethodCounter = 0;
private static EmergencyAbortListener mEmergencyAbortListener;
private FrameFixture workbenchFrame;

robot2 = BasicRobot.robotWithNewAwtHierarchy();
GuiActionRunner.execute(new GuiTask() {
#Override
protected void executeInEDT() throws Throwable {
ApplicationLauncher.application(ProgramRun.class).start();
}
});
} else {
// the second test method see all before created gui components
robot2 = BasicRobot.robotWithCurrentAwtHierarchy();
}
testMethodCounter++;
robot2.settings().idleTimeout(myIdleTimeout);
workbenchFrame = WindowFinder.findFrame(FrameNames.WORKBENCH.getName()).withTimeout(10000)
.using(robot2);
}
#After
public void tearDown() {
// current window will not be closed
robot2.cleanUpWithoutDisposingWindows();
}
#Test
public void someSmokeTest() throws Exception {
Pause.pause(1000);
// perform some test specific gui actions
// here is very important moment, I need new robot because
// workbenchFrame.button(ButtonNames.SOME_BUTTON_NAME).click(); creates new dialog
// which will be avilable in AWT stack after creation
robot2.cleanUpWithoutDisposingWindows();
robot2 = BasicRobot.robotWithCurrentAwtHierarchy();
// the new Robot needs timeout setup
// without this I have long breaks between gui events
robot2.settings().idleTimeout(myIdleTimeout);
workbenchFrame.button(ButtonNames.SOME_BUTTON_NAME).click();
DialogFixture dialog = WindowFinder.findDialog("dialog2")
.withTimeout(5000).using(robot2);
// some actions on the dialog
// once again next new dialog
workbenchFrame.menuItem(MenuItemNames.NAME).click();
robot2.cleanUpWithoutDisposingWindows();

// and idleTimeout setup once again, new Robot needs new setup
robot2.settings().idleTimeout(myIdleTimeout);
// next actions + assertion
}
