Hi Tony,
sorry, let me clarify:
QT's co-oridnate system starts at the top left, right?
So when I scale the window by dragging the left side (or the top), the
point of origin changes and thus I expect a different global position
for the widget.
The reason I am tying to determine the exact geometry of the parent
application is because I am trying to implement something like an
invisible slider, a mode where the use can click+drag anywhere in the
host application to change a certain value. Upon release the mode
disables itself until a hotkey is pressed again.
E.g. if the host application is a video player, I am trying to implement
a mode where the user can hit a hotkey, then click&drag anywhere in the
player to scrub through the video.
I'm sure there are better ways to go about this (and I'd love to hear
advise on this), but at the moment, as a proof of concept, I am creating
a transparent widget that catches the mouse event and emits the required
signal, and I'd like for that widget to perfectly sit on top of the
parent app so if the user click/drags outside of it, it won't have any
effect.
Ideally I'd just force the mouse event to my QObject rather than create
an transparent widget, but I don't know if this is possible?
Does that make sense?
Cheers,
frank

Hi Frank,
I don't understand what you are asking! Why do you expect that
changing the window size will change the position? You say 'resulting
in an offset for my widget' - sounds like you are adding the new pos
instead of just using it?
Tracking foreign native windows is pretty rare. You need to provide a
cut-down version of what you are doing so others can easily run it.
Regards,
Tony

anybody?
is this a bug?

Hi,
I am trying to figure out my host application's window geometry
reliably and am struggling a bit.
I use QApplication.activeWindow().geometry() to drive my custom
widget's geometry (I need to sit exactly on top of the host
application).
All works fine and my widget sits exactly on top of the host
application window, until the host app is scaled by dragging one
of it's sides out or in. After that
QApplication.activeWindow().geometry() still returns the same
exact position, though the size is correct, resulting in an offset
for my widget.
Turns out scaling windows on OSX by dragging their edges doesn't
seem to update QApplication.activeWindow().pos()
As soon as I grab the title bar and move the host app a tiny bit,
QApplication.activeWindow().pos() seems to be updated correctly.
Is there a fix/workaround for this?
Cheers,
frank
