It seems that it doesn't really matter. The DialogBox itself works fine,
and whether I call setFocus() immediately or through a DeferredCommand, the
result is the same.
What is not clear is why there is a KeyUp event fired at all. I am not
even listening for keyup in the dialog. I just have a close button that I
give the focus to, so when Enter is pressed, it "auto-clicks" the close
button for me. This I see is working as expected because I get an onClick
event sent to my button.
I removed the setFocus() call in the onClick() event handler of the dialog's
close button, and then it fires the onClick event as expected and I see no
KeyUp event.
But if I put the setFocus() call in the onClick() event handler of the
dialog's close button, it first fires the onClick event as expected, but I
then get a KeyUp event on the TextField that received the focus (it does
have a KeyUp handler registered).
Here's the close button's onClick code:
closeButton.addClickHandler(new ClickHandler() {
public void onClick(ClickEvent event) {
Object src = event.getSource();
GWT.log("ExceptionDialog onClick source: " + src.getClass()
+ "; event: " + event.toDebugString(),null);
dialog.hide();
if ( giveFocusBackTo != null )
{
DeferredCommand.addCommand(new Command() {
public void execute() {
giveFocusBackTo.setFocus(true);
giveFocusBackTo = null;
return;
}
});
}
}
});
If I comment out the giveFocusBackTo.setFocus(true), it works as expected,
but when I return from the dialog, my field doesn't have the focus that I'd
like it to have. If I have it like above, I'll get both an onClick and a
KeyUp event:
[INFO] ExceptionDialog onClick source: class
com.google.gwt.user.client.ui.Button; event: event: ClickEvent:
[INFO] myhandler keyup source: class
com.google.gwt.user.client.ui.PasswordTextBox; event: event:
KeyUpEvent:[13];
So the question is why does setting the focus in the dialog box cause a
KeyUp event to fire, but if I don't do the focus, only the click occurs and
no keyup event occurs?
