frameworks: reenable the updateColorPalette slot
Review Request #114619 - Created Dec. 22, 2013 and submitted - Latest diff uploaded
This is a little bit hackish, so second opinion is welcomed (required). Back in KDE4 there was KGlobalSettings::kdisplayPaletteChanged() signal, which was generated, when DBus notification from kcontrol (?) arrived. Seems that with Qt5 QPA and its implementation in frameworks, this is gone. The recommended way is supossedly to * Note: If you derive from a QWidget-based class, a faster method is to * reimplement QWidget::changeEvent() and catch QEvent::PaletteChange. * This is the preferred way to get informed about palette updates. which doesn't work in a case of KateGlobal, which derives from QObject. So Loooking at the Qt5 kode, the QPA should send QEvent::ChangePallete to application object, which resends it to all widgets and to itself as QEvent::ApplicationChangePallete. So the solution simple taps to the event interface and listens for the right event.
none. `kcmshell5 colors` doesn't seems to change colors of running applications (at least for me and for now).
