<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;"><h1 style="font-size: 100%;text-rendering: inherit;padding: 0;white-space: normal;margin: 0;line-height: inherit;">The new Meta-key support for launcher opening doesn't work for closing at the moment. My analysis of the problem was as follows:</h1>
<ul style="padding: 0;text-rendering: inherit;margin: 0 0 0 1em;line-height: inherit;white-space: normal;">
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">KWin calls Applet::activated() over DBus</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Applet::activated() is connected to AppletInterface::activated()</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">AppletInterface::activated() is connected to setExpanded(true), which can only expand the launcher, but not the other way around</li>
</ul>
<h1 style="font-size: 100%;text-rendering: inherit;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Q: Why is Alt+F1 working though?</h1>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">A: The launchers seem to inherit the reimplementation function Dialog::focusOutEvent(..). Atleast when you delete line 1094 in dialog.cpp, which sets the visibility to false, it's not working anymore. Alt+F1 triggers the focusOutEvent(..) as a global shortcut.</p>
<h1 style="font-size: 100%;text-rendering: inherit;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Q: Why is it working with the Dashboard though?</h1>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">A: The dashboard doesn't use the expanded feature of the plasmoid, but rather connects directly to the AppletInterface::activated() signal and shows/hides an independent widget by getting triggered on it.</p>
<h1 style="font-size: 100%;text-rendering: inherit;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Solution:</h1>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Create new toggled() signal chain in KWin, Applet, AppletInterface, which tests the current expanded state and setting it afterwards accordingly to its opposite. This diff here in plasma-framework is the first one, the others are dependent on. The others are on Phabricator:</p>
<ul style="padding: 0;text-rendering: inherit;margin: 0 0 0 1em;line-height: inherit;white-space: normal;">
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">kwin: https://phabricator.kde.org/D3077</li>

</ul>
<h1 style="font-size: 100%;text-rendering: inherit;padding: 0;white-space: normal;margin: 0;line-height: inherit;">Need feedback regarding:</h1>
<ul style="padding: 0;text-rendering: inherit;margin: 0 0 0 1em;line-height: inherit;white-space: normal;">
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Should we remove the activated() signal chain? Is it used somewhere else than KWin?</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Could a race condition occur if we deexpand the applet while at the same time setting the visibility to false through focusOutEvent()? My tests until now don't suggest it, but I haven't yet looked into it extensively.</li>
