David Hurka requested to merge davidhurka/okular:connect-preferred-screen-to-kconfigwidgets into master Aug 01, 2020

This adds PreferredScreenSelector, which is a QComboBox with an additional property which is accessed by KConfigWidgets.

In configuration dialog, Apply and Defaults are now connected with this combo box.
When opening the config dialog while the preferred screen is not connected, this setting is no longer reset immediately.
Port from QDesktopWidget (deprecated) to QScreen.
Bonus: QScreen allows to display some more information about the selected screen.

(before/after/after)

Test Plan

Get someone with enough displays, select one, disconnect it, reopen config dialog.

TODO

Port PresentationWidget to QScreen, otherwise PresentationWidget and PreferredScreenSelector assume different screen lists. See !233 (merged).

Extracted from !202 (merged).
