I am making a Java GUI to go with my colleague's custom made R package, IntramiRExploreR, which includes a function made to create an interactive graphic via igraph and IntramiRExploreR's Visualisation function, using the following parameters:
Visualisation(miR,mRNA_type=c('GeneSymbol'),method,thresh,platform=Platform,visualisation = 'igraph',layout = 'interactive')
where miR is a vector made via selected JCheckboxes, and method, thresh, and platform are populated from JRadioButtons. I've no doubt the function itself and how the variables are filled in is correct, as I have run the function in R and run the function using a text output format and both run correctly.
The code first fills out a JTable correctly with the results from
Visualisation(miR,mRNA_type=c('GeneSymbol'),method,thresh,platform=Platform)
which outputs text accessible using
caller.getParser().getAsStringArray(//one of seven parameters)
then provides a JButton to use the same parameters and objects to call the aforementioned igraph function in R. However, when the JButton is clicked, the igraph is created but then its frame is disposed as soon as the graphic is fully made. The second time the button is clicked, calling the function again, the provided error is:
Exception in thread "AWT-EventQueue-0" com.github.rcaller.exception.ExecutionException: Can not run C:\Program Files\R\R-3.3.0\bin\x64\Rscript.exe. Reason: java.lang.IllegalThreadStateException
Should I create new thread to handle the igraph visualisation, or is there some method in RCaller I am missing that can handle this? Is Java emptying its memory of my objects after I call a second RCaller and RCode block?
Here's what of my code I can show without violating my agreement to confidentiality:
public void actionPerformed(ActionEvent e){//if goButton is clicked
if(e.getSource() == goButton){
JFrame resultFrame = new JFrame("Results: For full readout, use export button below.");//creates entire resultFrame
resultFrame.setLayout(new BorderLayout());

The area of concern is the ActionListener for my JButton vis. I am absolutely certain that all else is well, but the igraph is unresponsive at first after populating and then a second call provides the IllegalThreadException error.
This is what I would check first:
The GUI can NOT be modified from a NON gui thread.
Make sure you have a background thread that passes the info to the GUI. Otherwise the GUI will become unresponsive until it finishes the processing (this is in the scenario of no background thread)
You can always put a gui runnable around the actionPerformed code.
In your case
SwingUtilities.invokeLater(new Runnable() {...});
I tried to put a simple icon in a JPanel formatted with the BoxLayout.
JPanel panel_4 = new JPanel();
contentPane.add(panel_4, BorderLayout.CENTER);
panel_4.setLayout(new BoxLayout(panel_4, BoxLayout.X_AXIS));
ImageIcon seven= new ImageIcon("C:\\Users\\alewe\\workspace\\SlotMachine\\Lucky_Seven-128.png");
JLabel lblNewLabel_1 = new JLabel(seven);
panel_4.add(lblNewLabel_1);
When I ran the code it gave me the error "Some characters cannot be mapped using "Cp1252" character encoding", I saved by UTF-8, now it starts but I can't see the icon.
Maybe if you use setIcon will help you:
ImageIcon seven= new ImageIcon("C:\\Users\\alewe\\workspace\\SlotMachine\\Lucky_Seven-128.png");
JLabel lblNewLabel_1 = new JLabel();
//Set your icon to your label
lblNewLabel_1.setIcon(seven);
panel_4.add(lblNewLabel_1);
You can read more about icons here
you will need a inputstream to read the picture. use it like this:
File f = new File("filepath");
InputStream in=new FileInputStream(f);
if (in != null) {
ImageIcon imageIcon = new ImageIcon(ImageIO.read(in));
label.setIcon(imageIcon);
} else {
LOG.debug("No icon found...");
}
I'm trying to build simple calculator gui with display and 9 buttons
public void init()
{
setSize(60,80);
inf = new InfoButton(this);
zero = new CalcButton(this,"0");
one = new CalcButton(this,"1");
add = new CalcButton(this,"+");
sub = new CalcButton(this,"-");
div = new CalcButton(this,"/");
mlt = new CalcButton(this,"*");
modu = new CalcButton(this,"%");
blank = new JButton("");
wys = new Wyswietlacz(); // its JTextPane
wys.setSize(60,20);
przyciski = new JPanel();
przyciski.setSize(60,60);
przyciski.setLayout(new GridLayout(3,3));
przyciski.add(zero);
przyciski.add(one);
przyciski.add(add);
przyciski.add(sub);
przyciski.add(mlt);
przyciski.add(div);
przyciski.add(modu);
przyciski.add(inf);
przyciski.add(blank);
calosc = new JPanel();
calosc.setLayout(new BoxLayout(calosc,BoxLayout.Y_AXIS));
calosc.add(wys);
calosc.add(przyciski);
calosc.setSize(60,80);
add(calosc);
}
and in main i make frame with size (60,80) but when i make it visible all i can see is display and one row of buttons. What am i doing wrong?
Call setPreferredSize(..) instead of setSize() on wys and przyciski. Then use JFrame's pack() instead of specifying a size for it.
I need to build BlackJack game as an study project.
I want build it with SWING GUI. What I need it just divide the screen in 2 parts, and then to be able insert elements (in my case it's extended JButton with signed ImageIcon) using absolute (x, y) position relative to specified part.
Something like that:
I came from developing under Android, where you can work with elements in very simple way, and I feel lost in SWING. There aren't AbsoluteLayout or something like that?
Here is one example of my several attempts to this:
public void run() {
// TODO Auto-generated method stub
JFrame jFrame = new JFrame("Blackjack");
jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Container pane = jFrame.getContentPane();
Insets insets = pane.getInsets();
URL url = ClassLoader.getSystemClassLoader().getResource("10_of_clubs.png");
BufferedImage bi = null;
try {
bi = ImageIO.read(url);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Image resizedImage = bi.getScaledInstance(128, 186, 0);
ImageIcon icon = new ImageIcon(resizedImage);
ImageButton imgButton = new ImageButton(icon);
imgButton.setPreferredSize(new Dimension(128, 186));
ImageButton imgButton2 = new ImageButton(icon);
imgButton.setPreferredSize(new Dimension(128, 186));
pane.setLayout(new GridBagLayout());
JPanel headPanel = new JPanel();
JPanel headPanel2 = new JPanel();
GridBagConstraints cns = new GridBagConstraints();
cns.gridx = 0;
cns.gridy = 0;
cns.weightx = 0.5;
cns.weighty = 0.2;
cns.anchor = GridBagConstraints.FIRST_LINE_START;
cns.fill = GridBagConstraints.BOTH;
headPanel.setBackground(Color.RED);
headPanel.add(imgButton, cns);
GridBagConstraints cns2 = new GridBagConstraints();
cns2.gridx = 0;
cns2.gridy = 0;
cns2.weightx = 0.5;
cns2.weighty = 0.2;
cns2.anchor = GridBagConstraints.FIRST_LINE_START;
cns2.fill = GridBagConstraints.CENTER;
headPanel2.setBackground(Color.BLUE);
headPanel2.add(imgButton2, cns2);
pane.add(headPanel);
pane.add(headPanel2);
jFrame.setSize(800, 600);
jFrame.setVisible(true);
jFrame.setLocationRelativeTo(null);
}
That what I get:
Tnx.
if you want absolute layout, please take a look at: http://docs.oracle.com/javase/tutorial/uiswing/layout/none.html
in general to read about layouts in java you can take a look at:
http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html
here is all java swing components: visual guide:
http://docs.oracle.com/javase/tutorial/uiswing/layout/visual.html
I think you can use JSplitPane (http://algo.math.ntua.gr/~symvonis/other-material/java_material/JavaTutorial/uiswing/components/splitpane.html) to create vertical separation
Since you have overlapping elements you can:
Use your existing JButtons with images inside a JLayeredPane. Put your cards on different layers for a clean rendering. Set the position of your Cards absolute with 'setBounds()'
Draw your cards with absolute position yourself using a Canvas. If you take this approach, you will also have to do your Click handling yourself (check if a click is inside a card.)
How can I display jpg image which I stored in arraylist in JPanel?
Im not able to display the jpg files in the JPanel.
String[] pictureFile = {"A.jpg","B.jpg","C.jpg"};
List<String> picList1 = Arrays.asList(pictureFile);
Collections.shuffle(picList1);
ImageIcon icon = new ImageIcon("picList1.get(0)");
JLabel label1 = new JLabel();
label1.setIcon(icon);
JPanel panel = newJPanel;
panel.add(label);
You should not put the call to the array in quotes.
Instead, you should try the following:
ImageIcon icon = new ImageIcon(picList1.get(0));
The problem is in the line
ImageIcon icon = new ImageIcon("picList1.get(0)");
It's interpreting the string as a file name. You should just need to unquote the picList1.get(0) bit.
