Fixes common and frequent crashes introduced by 6c627ea044.
Otherwise the engine will try to delete it. The docs say:
NOTE: A QObject singleton type instance returned from a singleton type provider
is owned by the QML engine unless the object has explicit
QQmlEngine::CppOwnership flag set.
A lambda can only be converted to a function pointer if it does not capture
anything. Just specifying a default capture even if it does not capture anything,
prevents this. In newer Qt this actually ended up calling the std::function
(which is much heavier than function pointers) overload which was introduced
only after Qt 5.12.
Since a checkbox is a subclass of AbstractButton, it can be given an
icon. QWidgets checkboxes will faithfully display this icon, but
PlasmaComponents3 ones will not. They should. :)
I will submit a similar change for the QQC2 checkbox style
to make them consistent.
if KDeclarative::runtimePlatform() is set, then filter applets
that have formfactors set and don't match, in order to not
show on the phone applets that are desktop only
in desktop case, list all applets, for maximum retrocompatibility,
to be reconsidered for kf6
Compare API dox of Q_DECLARE_METATYPE:
"
Some types are registered automatically and do not need this macro:
* Pointers to classes derived from QObject
* QPointer<T>, QSharedPointer<T>, QWeakPointer<T>,
where T is a class that derives from QObject
"
This is a ABI-compatible change, as this just replaces explicitly
defined template code (by the Q_DECLARE_METATYPE macro use) with the
generic predefined one picking up pointers to QObject subclasses.
So instead of the custom explicitly template overload
template <>
struct QMetaTypeId< TYPE >
{ /**/ static int qt_metatype_id() {/**/} };
the predefined template overload one is picked up via
template <typename T>
struct QMetaTypeId : public QMetaTypeIdQObject<T>
{ /**/ };
template <typename T, int =
QtPrivate::IsPointerToTypeDerivedFromQObject<T>::Value ?
QMetaType::PointerToQObject :
/**/ 0>
struct QMetaTypeIdQObject
{ /**/ };
template <typename T>
struct QMetaTypeIdQObject<T*, QMetaType::PointerToQObject>
{ /**/ static int qt_metatype_id() {/**/} };
And thus the constexpr code using QMetaTypeId<T>::qt_metatype_id(),
for which all this is done, evaluates as before.

The old code calling
qRegisterMetaType<Plasma::T *>("T");
was broken, as it registered for the name "T", not the pointer
type "T*". Things still work though as that registration is also
covered due to
qmlRegisterInterface<Plasma::T>("T");
internally also calling
qRegisterMetaType<Plasma::T *>("T*");
so that in the end "T*" was registered and mapped to the right type.
Currently, I see that the network icons aren't visible enough. For example, I find it difficult to determine the signal strength of the network without peering. I would like these icons to be more visible, and therefore I propose to use 35% opacity for faded elements. As for me, this solution makes determining the signal level more convenient and the icons more informative.
Plasma dialogs are already marked as not being shown in the task manager
and the pager. We should similarly omit them from the task switcher, for
the same reasons.

We should use the normal arrow cursor when a list item is hovered.
The hovered state is depicted with a highlight already, so the hand
cursor is unnecessary and doesn't go well with the rest of the desktop.
The sizes of the context buttons on the list item were being overridden
for no apparent reason. Let's stop doing that so that the button sizes
are consistent with other PC3 button sizes.
Make sure the shadow item--which includes the hover effect, if present--can
be shown when the ToolButton is focused, and also always omit the shadow
when the ToolButton is flat.
Now all of them have a base height of units.gridUnit. Combined with
the standard 6px margins it works out to make all of these controls
a uniform 30px tall with the default Noto Sans 10 font. If the font
is changed or the size is increased, even to absurd levels, all of
them scale evenly.
The PC3 version was missing the clear button and show password button,
which the PC2 version has. This should allow us to port more things to
use the PC3 version.
relay->checkQueueing emits a signal to all observers. As it's a signal
anything can happen at that point. It's seemingly common for a receiver
to connect/disconnect a new visualisation which in turn alters
d->relays.
This broke when a foreach (with implicit shallow copy) was ported to a
for statement.
This report contains a good analysis and test case

Currently, I see that the icons that show available and connected networks are not visible enough. For example, I find it difficult to determine the signal strength of the network without peering. I would like these icons to be more visible, and therefore I propose to reduce the opacity of faded lines. As for me, this solution makes determining the signal level more convenient and the icons more informative.
BUG: 423843
This changed the name of the types for which the classes where registered
from unnamespaced "Service", "ServiceJob", "DataSource" to the fully
namespaced "Plasma::Service", "Plasma::ServiceJob", "Plasma::DataSource",
so making the old names no longer known to the system and thus breaking
support for any invokable methods which use the unnamespaced type name.
And not only that, qmlRegisterInterface<T>("Name") also registered the
classes' pointer counterparts T* by the name "Name*", so here
"Service*", "ServiceJob*", "DataSource*". While the new again instead
does this with the fully namespaced names "Plasma::Service*",
"Plasma::ServiceJob*", "Plasma::DataSource*", so also breaking support
here.
This reverts commit 7c4f5c5f1e.
