How it is correct to create Tab programmatically

oshmianski · August 3, 2012, 5:58am

Hi!

How it is correct to create Tab programmatically?
I have CControl and CGrid where are added 3 tabs.

I create new tab (new DefaultSingleCDockable), add (addDockable) it in CControl, then do setLocation and setVisible (true).

But sametime after DnD this new tab appear error:

This is a strange exception, I’m not certain if your construction of the tabs and the exception have any relation. It could be coincidence.

I can’t do anything without stacktrace: next time the exception happens please post the part of the exception which does not repeat itself (should be at the bottom of the print out), because the bug is more likely to be found in that part.

sametime there is no any more, just this:

	at java.awt.AWTEventMulticaster.removeInternal(AWTEventMulticaster.java:892)
	at java.awt.AWTEventMulticaster.remove(AWTEventMulticaster.java:128)```

line at java.awt.AWTEventMulticaster.remove(AWTEventMulticaster.java:128) repeats many-many times (~500-1000).

2) Sametime there is:

happens ecxeption 1) (look above)

I could not reproduce the error. But it seems to be the same issue all the times (everything that follows the first exception is likely caused by corrupted data structures). The only idea I have right now would be an issue with multi threading. Are you using multi threading when creating the layout, for example do you make the frame visible in the “main” method and load the layout afterwards in the “main” method?

oshmianski · August 6, 2012, 12:22am

no, i am not using multi threading.

today new exception:

my application is JApplet.

You think there is any chance you can give me your applet, at least the part that sets up and interacts with the framework? Because I’m a bit out of ideas on how this can happen, looking into the application may help.

For now I always got the same exception(s). I added a breakpoint that stops the entire VM when the exception is thrown. The stacktraces always look the same: this exception is caused by multi-threading. Have a look at these images:
image 1 and image 2. As you can see, the MySwingWorker is removing a HierarchyListener, while at the same time the EventDispatcherThread tries to fire a HiearchyEvent.

This could be solved by calling any method of “StatusPanel” from the EDT (using EventQueue.invokeLater/invokeAndWait).

oshmianski · August 9, 2012, 9:25am

I not absolutely understood where you suggest to use EventQueue.invokeLater/invokeAndWait?
I should use SwingWorker, otherwise the interface will be frozen when loading large data.

Beni · August 9, 2012, 11:47am

You can use the SwingWorker, but you must not access the UI from within the SwingWorker. As an example have a look at your class “LoadItemsTest” and its method “run”. This “run” method is called from a custom thread (created by the SwingWorker), but then within “run” you have calls like “panelStatus.setPBIndenterminate(true);”. But “panelStatus” is part of the UI, hence you access the UI from a second thread.

At least the SwingWorker class from the JRE 6 has special methods like “publish” and “process” which are designed to solve exactly this issue. In your case you would access “panelStatus” only from the “process” method. Using “EventQueue.invokeLater” from within the “run” method of “LoadItemsTest” would have the same effect.

Thanks, Beni. It seems helped.

Throughout a subject…
I am a programmer of Lotus Notes. In Notes of documents it is possible to embed java applets. For this reason my project is JApplet. And so, at start of embedded java applet internal JVM starts. Further there is a work in an applet. Here all while is good. But after end of an applet end close it, the JVM remains started (it is feature of work of Lotus Notes). And here problems begin - memory taken with an applet isn’t released almost.

Possibly it again my Java illiteracy, but can be memory leak because of dockingframes?
I cause cControl.destroy () in stop () an applet, but sometimes code process doesn’t occur further. And I can’t catch a mistake, though I use “try catch”.

oshmianski · August 10, 2012, 8:07am

Beni, sorry, my mistake.

I seem understood.
It is feature of Lotus Notes. The code in JApplet.stop() needs to be turned in EventQueue.invokeAndWait. Then it is completely carried out, differently can break on a half.

Thanks a lot for the help.

Beni · August 10, 2012, 9:41am

Alright, I’m happy you solved the issue. If you have any more questions, please ask them.
