How to use windowStateListener?
Hi,
I want to do a check before a frame is closed, so that for unsaved content,
I can veto the closing.
and here is my code:
......
private Vote vote = Vote.APPROVE;
@Override
public void initialize(Map<String, Object> namespace, URL location,
Resources resources) {
this.getWindowStateListeners().add(new WindowStateListener.Adapter() {
@Override
public Vote previewWindowClose(Window window) {
if (Compose.this.isEdited()) {
closeConfirmPrompt.open(window, new SheetCloseListener() {
@Override
public void sheetClosed(Sheet sheet) {
if (closeConfirmPrompt.getResult()
&& closeConfirmPrompt
.getSelectedOptionIndex() == 1) {
vote = Vote.APPROVE;
} else
vote = Vote.DENY;
}
});
return vote;
} else
return Vote.APPROVE;
}
});
However, the result is the window is closed before the prompt show up.
why prompt is bypassed ?

Yes, that's a good idea.

Noel, do you think could be useful to write it in Javadoc for that
method (could be useful even fore others in future) ?
And maybe even in other places ... if someone has suggestions, tell me.
Bye,
Sandro

Sorry, Prompt#open() is not a synchronous call, it schedules an event to
open the window.

Thanks Chris,
I implemented your rework into my program and it works.
I just wonder if this behavior is expected. I meant the behavior of carry on
closing the window without waiting the opening of prompt.

Re: How to use windowStateListener?

Brendan,
Sorry for the slow reply. I have only just been able to download your
sample (which was exactly what was needed).
The problem is that your WindowStateListener is opening a Prompt, but
the program execution doesn't wait for the user to click on one of the
buttons. It just carries on and returns Vote.APPROVE, which means
that the Frame gets closed.
I have attached a slightly reworked TestFrame class that opens the
Prompt and returns a Vote.DENY to stop the Frame from closing. Any
time later, if the 'Yes' button is pressed, it will explicitly ask for
the Frame to be closed after setting the return value to Vote.APPROVE.
public class TestFrame extends Frame implements Bindable {
@BXML
private Prompt closeConfirmPrompt;
private Vote vote = Vote.DENY;
@Override
public void initialize(Map<String, Object> namespace, URL location,
Resources resources) {
this.getWindowStateListeners().add(new WindowStateListener.Adapter() {
@Override
public Vote previewWindowClose(final Window window) {
if (vote == Vote.DENY) {
closeConfirmPrompt.open(window, new SheetCloseListener() {
@Override
public void sheetClosed(Sheet sheet) {
if (closeConfirmPrompt.getResult() &&
closeConfirmPrompt.getSelectedOptionIndex() == 1) {
TestFrame.this.vote = Vote.APPROVE;
window.close();
}
}
});
}
return vote;
}
});
}
}
I can't help thinking there is a tidier way of doing this, but my
brain is a bit rusty because I have been away from Pivot for a couple
of months. Anyway, I hope that helps.

Hi Chris,
I just made a small completed program for you.Please try to close the frames and I added listener to prompt for confirmation before it close but didn't work.

Re: How to use windowStateListener?
Posted by Chris Bartlett <cb...@gmail.com>.
Could you please post a complete, small example of this?
How is the Frame closed? Are you talking about closing the
org.apache.pivot.wtk.Frame or the operating system window (which is a
java.awt.Frame I think) in a desktop application?
