Bug ID: 434620
Summary: Changing size constraint doesn't update title bar
buttons position
Product: kwin
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: decorations
Assignee: kwin-bugs-n...@kde.org
Reporter: damir_poro...@live.com
Target Milestone: ---
SUMMARY
kwin seem to be not updating the tittle bar buttons position when the buttons
count change. We have a use case where we switch to fixed size (which has only
two buttons, minimize and close), then adjust the widget size (here the buttons
position is probably updated), then we switch back resizable size (this adds
the third button, maximize), but the button position stays the same and the
maximize buttons pushes the close button outside the visible frame.
STEPS TO REPRODUCE
1. Set widget size constraint to fixed:
mLayout->setSizeConstraint(QLayout::SetFixedSize);
2. Adjust widget size:
QWidget::adjustSize();
3. Revert widget size constraint back to value that was previously set:
mLayout->setSizeConstraint(QLayout::SetMinAndMaxSize);
OBSERVED RESULT
The close button is no longer visible, if you enlarge the widget manually so
that you move the right border further to the right side, the close button
becomes visible again.
EXPECTED RESULT
Changing size constraint in a way that the tittle bar button count is changed
should also update the position of the buttons so that all buttons are visible.
