<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">::activateWindow() should be equivalent to "XSetInputFocus(display, winId(), XRevertToParent, X11->time);" unless
a) _NET_ACTIVE_WINDOW is listed in _NET_SUPPORTED on the root window (supposed to be set and withdrawn by window managers, crash on exit?)
AND
b) Qt::X11BypassWindowManagerHint is NOT set on the toplevel window
OR
c) the window is not mapped/waiting for a mapping notification</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">=> If the problem occurs, login aside (VT1 or ssh) and</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">export DISPLAY=:0
xprop -root | grep _NET_ACTIVE_WINDOW</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If that's emtpy, focus setting fails on either "qt_widget_private(tlw)->topData()->waitingForMapNotify" (qt bug in event handling? missing "XSync(dpy, false)"? events are being processed after show) or "X11->time" being superseded by a more recent/future XSetInputFocus call ("fixed" by passing CurrentTime)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">If the feature /is/ listed, that's a bug caused by a crashing WM => setting Qt::X11BypassWindowManagerHint will likely be sufficient.</p></pre>

But without it, input dialogs do not correctly get focus and keyboard shortcuts don't work.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">KDM does call activateWindow() on opened dialogs, but this doesn't seem to have the desired effect without a window manager running. And if you hover the mouse over a widget, it visually looks like it has focus, but often it doesn't accept input anyway.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch sets the input focus via XSetInputFocus() instead, this also has the positive side-effect that a widget retains the focus if you move the mouse away.</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I also tested with onboard keyboards (xvkbd and kvkbd), both work fine. Before, kvkbd didn't work at all (the text input widget lost focus as soon as you moved the mouse to the OSK) and xvkbd only works if you forced the focus to the text input widget via its "Focus" button (from which this patch was inspired actually ;-) ).</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Other openSUSE users have tested this as well, and the patch is even part of openSUSE's official package since January.
