Bring dialog to front, call attention to it

[ataylor]

I have a dialog instantiated like so when user presses a button:

MyDialog d=new MyDialog();
Unigine::Widgets::addChild(d);
while(d.isDone() == 0) wait;
Unigine::Widgets::removeChild(d);
delete d;

If the user presses that button again without closing the first dialog, I avoid re-opening a second dialog. This much is working in my implementation.

To expand on this, if a dialog already exists, I would like to bring it to the front, and also visually call attention to it (perhaps by flashing briefly) if possible. Is there an example somewhere that shows how to do either of these things?

Hi Taylor,

 

for getting widget on top, you can just call setFocus. Unfortunatelly, there is no implemented flashing effect, you can write it for your own: maybe something like this:

window.setFocus();
thread([]() {
	forloop(int i = 0; 3) {
		window.setHidden(1);
		window.arrange();
		wait;
		window.setHidden(0);
		window.arrange();
		wait;
	}
	window.setFocus();
});

Try it. And other way is to open modal dialog by setPermanentFocus.

Calling myDialog.setFocus() does not have any visible effect. The window is not brought to the front, remains where it was in Z-order.

Unfortunately, setPermanentFocus is not an option in this case. If opened dialog has permanent focus, user cannot interact with other dialogs or with main window.

 

 

 

Thread with widget.setColor and sleep functions is sufficient for flashing effect, thank you for the idea.

Upon further investigation, it appears that setFocus() is setting focus to the dialog, but not causing it to render in front of other dialogs. Clicking on area where windows are overlapping gives unexpected results.

 

I will put together a test scenario for debugging.

Here is small test scenario.

 

Double-click the item in the treebox to open a dialog.

Re-arrange windows such that they are both visible but still overlapping.

Double-click the item in the treebox again.

 

The dialog is not brought to the foreground.

If you are using interface plugin, you need to set focus for InterfaceWindow:

#ifdef HAS_INTERFACE
	gTestDialog.getInterface().setFocus();
#else
	gTestDialog.setFocus();
#endif

Ah, that was what I needed. Thank you!
