I have a dialog like this opened:

int cancel = Dialog.ask("synchronizing...", new String[] {"Cancel"}, new int  []   {Dialog.CANCEL}, Dialog.CANCEL);

When the "Cancel" button of the dialog is clicked everything is ok, but when it is not clicked I would like to move the dialog out of my application. How can i get that?

In theory you should be able to create an instance of Dialog:

Dialog dialog = new Dialog( "synchronising...", new String[] { "Cancel" }, new int[] { Dialog.CANCEL }, Dialog.CANCEL, Bitmap.getPredefinedBitmap(0) );
dialog.doModal();

and then use the .close() or .cancel() method to dismiss it but when I simulate some external event by passing the dialog to another thread and invoking either method I get:

java.lang.IllegalStateException

Hi, I tried that idea. I make my own dialog box and push it to the display, like this:

cancelDialog = new CancelDialog("synchronizing...", new String[] {"Cancel"},
        new int[] {Dialog.CANCEL}, Dialog.CANCEL, Bitmap.getPredefinedBitmap(Bitmap.INFORMATION));
    UiApplication.getUiApplication().pushGlobalScreen(cancelDialog, 0, UiEngine.GLOBAL_MODAL);

..but when I want to close it, nothing happens, doesn't throw an exception even. I used several ways to close it.

1)

    cancelDialog.cancel();
    cancelDialog.close();
    UiApplication.getUiApplication().repaint();

2)

    UiApplication.getUiApplication().popScreen(cancelDialog);

...or something like this. I have no idea what is wrong.

1) You need to close Dialog from another thread, since doModal() or ask() methods block current thread.

2) Since you close dialog from outside UI event-handling thread, you need to use something like this:

_uiApplication.invokeLater(new Runnable()
{
    public void run()
    {
        _dialog.close();
    }
});

    cancelDialog = new CancelDialog("Synchronizing...", new String[] {"Cancel"},
        new int[] {Dialog.CANCEL}, Dialog.CANCEL, Bitmap.getPredefinedBitmap(Bitmap.INFORMATION));
    UiApplication.getUiApplication().pushModalScreen(cancelDialog);

......and trying to close it

UiApplication.getUiApplication().invokeLater(new Runnable(){
            public void run() {
              cancelDialog.cancel();
              cancelDialog.close();
              updateLayout();
            }
          });

Well it is not working that way , but thank you for the advice!

Do you call second piece - with invokeLater() - from other thread?

[pa4o85]

I called these two pieces in the main thread. Firstly I have opened the dialog, then started another thread (it makes some things) and at the end i closed the second thread and i wanted to close the dialog box that is displayed to the screen while the second thread is working. At the end of the second thread I am again in the main thread and want to close the dialog programatically, not as clicking the trackwheel.
