That is - as far as i know - not possible in the new signal/slot syntax which is probably why you used a lambda.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">You could use the old signal/slot syntax which does allow signal -> signal mapping:
QObject::connect(obj, SINGAL(), otherObj, SIGNAL());</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">The default return is false.
Then you have 5! other places that return false as well. With the default being false, you don't have to check other false conditions. All you have to check for is the cases that will be true, which would be:</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">if (m_host->showAllItems() && m_category == Category::ShownTasksCategory) {
return true;
}</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">and then obviously check for the cases that could be true or false (aka, your last if / else if statement.</p></pre>

This way we don't need to keep three different models in sync which has shown to often break, especially when item status change. Makes the code significantly easier to understand.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">One thing I noticed is that there doesn't seem to be a way for a plasmoid to specify a category, so when I uncheck "Miscellaneous", all items but KMix (which is in the hardware category) disappear. Since we're moving away from most SNI apps to plasmoids, it would make sense to allow an applet so specify a category (either through Plasmoid attached object or in the desktop file (or we do a mapping from the PluginInfo-Categories to sys tray categories))</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Edit: Tried the PluginInfo-Categories mapping but it doesn't really fit. Eg. Battery is "System information" but should show up in the Hardware category or systray, likewise for Device NOtifier, and many other systray applets.</p></pre>
