D15307: Remove Context Help button by default

broulik added a comment.


  I always remove it from my window decoration also. However, I don't think we should just remove it.
  
  The button is only shown when a window sets `Qt::WindowContextHelpButtonHint`.
  As far as I can tell it is set by ksysguard (which has quite elaborate quick help btw!) , ksysguard, systemsettings, and others.
  It is also automatically added by Qt for any dialog windows, with a comment in the code
  
    // ### fixme: Qt 6: Never set Qt::WindowContextHelpButtonHint flag automatically
  
  There is an attribute `AA_DisableWindowContextHelpButton` that you can set on the `QApplication` to disable this.
  I think we should set this attribute in plasma-integration and then look at all the apps that explicitly set this flag and decide whether it should be removed or the quick help texts fixed/extended.
  
  I don't know if QML supports it, though, but I doubt it (it's old desktop stuff, and who wants desktops anyway lol), maybe Kirigami could even implement this, if deemed useful.
