I have a netbeans platform application,
The Output window consists of two tabs in which am able to embed one of the tab in to a separate component with the following reference,
http://wiki.netbeans.org/DevFaqOWTabEmbedding
However, when i tried adding actions to it , the actions are not coming up in UI .
IOContainer ioc = IOContainer.create(new IOC());
InputOutput io = IOProvider.getDefault().getIO("test",
new Action[]{
new OneAction(),
new TwoAction(),
new ThreeAction()},ioc);
am expecting the three actions to be shown in the newly created window.
Something like this,
But am getting only the white window.
However, if i don't embed the tab in to another component, the actions appear.
Any help?
IOC has empty implementation of IOContainer.Provider method
setToolbarActions(JComponent comp, Action[] toolbarActions)
you should add JToolbar in IOC and implement that method.

I added an UndoManager to a JTextPane in my application, but I can't get it work:
UndoManager undoManager = new UndoManager();
textpane.getDocument().addUndoableEditListener(undoManager);
When I manually type into the text pane, then try to undo the changes, nothing ever happens undoManager.canUndo() always returns false.
I also tried another way of adding the manager as follows:
textpane.getDocument().addUndoableEditListener(new UndoableEditListener()
{
#Override
public void undoableEditHappened( UndoableEditEvent e )
{
System.out.println("UndoableEditEvent");
undoMgr.addEdit(e.getEdit());
}
});
With the above code I can see in the output window that the undoableEditHappened( UndoableEditEvent e ) is called once at the start (most likely by a read call which loads the test file). When I make changes (via keyword) or insertText(...) calls, there are no further listener calls.
I found some similar questions here in StackOverflow, but the solutions were always alongs the lines that they had custom input methods for the JTextPane, I don't ... not that I know of.
What might I have overlooked?
I found out why the UndoableEditListener wasn't triggering.
I was calling JTextPane.read(Reader reader, Object object) after I had setup the Document listeners - What I didn't know was that calling the read(...) method creates and adds a new Document model to the JTextPane, which basically removed anything I had previously done to the old Document.
Solution
Work with the Document model after calling JTextPane.read(...)
I have problem with modal window. I call this two methods setIsModal(true) and setShowModalMask(true) but why my window isn't modal ?
Here is the Code :
Window summaryWindow = new Window();
summaryWindow.setWidth(950);
summaryWindow.setHeight(620);
summaryWindow.centerInPage();
summaryWindow.setCanDragReposition(false);
summaryWindow.setIsModal(true);
summaryWindow.setShowModalMask(true);
summaryWindow.setShowMinimizeButton(false);
summaryWindow.setTitle("Example");
summaryWindow.addItem(new Button("Example");
summaryWindow.show();
The exception you're getting is valid. In any GWT related technology, you'll find many API functionalities to set properties of GWT widget. For example, for a Window widget you have, setWidth, setHeight, centerInPage etc...
Now some of these properties MUST be applied before the widget is rendered in DOM of the browser & some of them MUST be applied after the widget is rendered in DOM of the browser.
ShowModalMask() is a property that you can set only before the widget is rendered.
centerInPage() is a property that renders Window in DOM of browser & that is the reason you're getting the exception.
Apply properties in a proper order (centerInPage() after ShowModalMask() in your case) to avoid this kind of exception.
I'm using smartgwt 2.4 : if I try your code with a button calling it enclosed in a method I get an error which indicated I cannot modify it with setModalMask (IllegalStateException - this property cannot be changed after the component has been created) .
After moving this call just after the instanciation it's working:
Window summaryWindow = new Window();
summaryWindow.setShowModalMask(true);
I don't really understand, but let me know if it's also working for you
I have a RCP applicaton from which I need to show a GEF Editor in a modal "dialog". But since the editor framework seems to be tightly coupled to the use of a workbench window etc I need to find a why to open a new workbench window (with its own WorkbenchWindowAdvisor etc) so that I can open my GEF editor within this workbench window. Once I get this workbenchWindow opened I will set the style of the WorkbenchWindow's shell to be application modal.
I have done this in a customer project using the following components:
A static class with a method openNewWindow(String type, ...). This is the method you call to open a new window. The type argument specifies the wanted type of window.
The class looks up the specified type via a new extension point to get an ILocalWorkbenchWindowAdvisor and the initial perspective ID.
It then saves the information in global variables and calls IWorkbench.openWorkbenchWindow(perspectiveID, ...)
In ApplicationWorkbenchAdvisor.createWorkbenchWindowAdvisor(...) a new advisor is create based on the saved ILocalWorkbenchWindowAdvisor - the returned advisor basically delegates all the postWindowCreate(...), etc to the same methods in ILocalWorkbenchWindowAdvisor...
If no ILocalWorkbenchWindowAdvisor is saved - which is the case for the very first window to be opened - the type "mainWindow" is looked up and used...
It works pretty well and let all parts of the project add new windows as needed.
Use the command "org.eclipse.ui.window.newWindow" to open a new window. In your WorkbenchWindowAdvisor.preWindowOpen(), set the shell style on the IWorkbenchWindowConfigurer to be application modal. You can also hide the coolbar, menu and status bars, so it looks more like a dialog than a window.
I am creating a web page with several tabs. To implement that I am using wicket AjaxTabbedPanel and several AbstractTab. In each tab I have tables with data and I am using a javascript script to make the tables sortable.
public TabbedPage() {
List<ITab> tabs = new ArrayList<ITab>();
tabs.add(new AbstractTab(new Model<String>("first tab")) {
public Panel getPanel(String panelId) {
return new TablePanel(panelId);
}
});
tabs.add(new AbstractTab(new Model<String>("second tab")) {
public Panel getPanel(String panelId) {
return new TablePanel(panelId);
}
});
add(new AjaxTabbedPanel("tabs", tabs));
}
When I load the page the table in the tab selected by default is sortable. However, as soon as I click any of the links to jump to other tabs (including the one of the tab already selected), none of the tables in any of the tabs allows me sort them (including the one that was previously working - the table in the default tab). If I refresh the page I can sort the table (of the tab selected in the moment of the refresh), but as soon as I click in any of links to switch tabs, the tables stop having the sortable capability again. Any ideas of why is this happening?
EDIT:
I just found that if I replace the AjaxTabbedPanel by TabbedPanel I don't have this problem. Although I'm still not sure why is that. Can anyone enlighten me?
add(new TabbedPanel("tabs", tabs));
Sorting the table by JavaScript is most likely a function called with a specific DOM-Id and seems to be executed 'onLoad'. it then accesses the currently displayed table and does it's work.
Changing the content of your Panel by Ajax doesn't trigger 'onLoad' so the function isn't executed again. TabbedPanel reloads the page and therefore executed your script.
Selecting a previous sortable table with AjaxTabbedPanel doesn't work because of the dynamically generated DOM-Ids.
Your solution is to add a AjaxCallDecorator to the links from AjaxTabbedPanel or to include the script or at least the function call to your tabbed panels.
At least this it what comes to mind without seeing any sources...
EDIT:
You might want to look at The Wicket Wiki. There's a description on how to call js after clicking an AjaxLink. That's exactly what should solve your problem.
Summary: Just add
link.add(new AttributeAppender("onclick", new Model("myTableSortingScript();"), ";"));
to the links generated by AjaxTabbedPanel.
In Wicket 6.0 you can run JavaScript on a component basis: Just override renderHead(IHeaderResponse response) for your component:
#Override
public void renderHead(IHeaderResponse response) {
super.renderHead(response);
response.render(new OnLoadHeaderItem("initalizeMe(\"" + getMarkupId() + "\");"));
}
initializeMe(mycomponentId) is executed every time the component is loaded by the AjaxTabbedPanel. This also works with the standard TabbedPanel.
No real idea since I'm not sure what the code is doing but I had a similar problem with my Panel Manager. Basically if you dynamically load HTML into a panel (a div or another element) using "innerhtml" script in the content will not be executed.
To get around this I scan the loaded content for "script" tags and append them using the DOM methods - this does run the script and makes it available. My "load" method is:
// Load Content
Panel.load = function(Content) {
// "null" the old (to clear it)
Panel.innerHTML = null;
// Load the content
Panel.innerHTML = Content;
// Load Scripts
var AllScripts = Panel.getElementsByTagName("script");
var AllScriptsCnt = AllScripts.length;
for (var Cnt = 0; Cnt < AllScriptsCnt; Cnt++){
var CurScript = document.createElement('script');
CurScript.type = "text/javascript";
CurScript.text = AllScripts[Cnt].text;
Panel.appendChild(CurScript);
};
};
Again, not sure if this is the issue, but it sounds pretty much on target from my experience.
I need some help. Is it possible to simulate a drag & drop without registering a component?
E.g. I click the mousekey anywhere on the window and hold the mousekey down, at this moment, I want to create or simulate a DragSourceEvent programmatically with Java.
Is this possible?
Update:
Regarding Bob's reply, at least I got it, I can create a listener for the drag & drop:
DragSource dragSource = new DragSource();
DragGestureListener listener = new DragGestureListener() {
public void dragGestureRecognized(DragGestureEvent event) {
event.startDrag (null, strSel) ;
...
}
}
listener.dragGestureRecognized(new DragGestureEvent(
new DragGestureRecognizer(dragSource, component) {
}, DnDConstants.ACTION_COPY, new Point(0,0), events ));
but unfortunately i get this exception:
java.lang.IllegalArgumentException:
source actions at
java.awt.dnd.DragSourceContext.(DragSourceContext.java:169)

any suggestions?
The question you asked:
I haven't tried it, but in theory you should be able to create the Event object and get a handle on the Swing Event Queue from one of the system classes. However without having a valid component, there may be problems when methods try to work with the event.
What you probably meant:
Registering events for a standard window -- you should be able to set up drag and drop support for an empty JPanel or JFrame, but it'll take some hacking. Drag & Drop is a pain to work with at this level when not built in -- I suggest using something like an invisible component or something instead.
