Subject: Emit QScreen::geometryChanged when the logical DPI changes
|
|
|
|
Add the missing call to QScreenPrivate::emitGeometryChangeSignals()
|
|
along with an emission of physicalDotsPerInchChanged()
|
|
since that is calculated from geometry and physical size.
|
|
|
|
Rearrange the code in
|
|
QGuiApplicationPrivate::processScreenGeometryChange()
|
|
to prevent duplicate emissions of geometryChanged(),
|
|
physicalDotsPerInchChanged() which this change would introduce.
|
|
|
|
Amends 5290027e3bab75f14fc0a2b7c206594d9cb91e76.
