<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;"><p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Panel popup dialogs along with other applications of Plasma::Dialog
(e.g. Kicker's submenus) currently don't correctly set WM_TRANSIENT_FOR
to the id of their parent window on X11. This causes them to interact
badly with auto-hide panels which do not set struts, e.g. Kicker's
submenus open behind the panel.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Internally, Dialog makes calls to QWindow::setFlags when its window
type is "Normal" (the default) and otherwise uses KWindowSystem's
setType. (Kicker's subclass, SubMenu, does an additional
KWindowSystem::setType call for NET::Menu). Neither CompactApplet
nor Kicker change their Dialog's 'type' property to anything else,
so their dialogs are "Normal", thus going the setFlags route with
no setType calls.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Dialog also sets its transient parent to the window the visualParent
item is inside of.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Now here is where things break down: QXcbWindow will update
WM_TRANSIENT_PARENT for in show(), but only when an inline function
called isTransient returns true. isTransient decides this based on
window type, which is determined from the flags set with
QWindow::setFlags. Calls to KWindowSystem::setType would have no
bearing on this; there seems to be no mapping back from external
state. This is why setting Dialog.type to e.g. "DialogWindow" does
nothing.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This patch takes the route of adding Qt::Dialog to the starting
flags - after all Dialog is a dialog. That means isTransient()
will consider the window to be a transient and those
setTransientParent calls Dialog does will not be ignored. In the
case of CompactApplet, no further calls to KWS::setType are done;
Kicker continues to call it with NET::Menu to get desired window
manager behavior.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In light testing everything still seems too work, with the added
benefit of fixing:
BUG:366278</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">That said, the weird mess of setFlags and setType and state in the
windowing system vs. Qt is horrible and sad.</p></pre>
