I notice that some applets/icons will change there color/birghtness a bit on
hover. The device-monitor applet does this as do any shortcuts or folders I
placed on the panel. How do I do this?

Functionality in QIcon as well (iconWidget might get it from there). Since I am using KIcon, well, very easy! Both myself and the original correspondent might have been best off starting with the iconWidget and that has a bona-fide clicked() signal! Without better docs, we start out with the sample code which is a bare applet subclass and no hints of other or added possibilities. ___ Plasma-devel mailing list Plasma-devel@kde.org https://mail.kde.org/mailman/listinfo/plasma-devel

If I remove mousepressEvent , doubleClickEvent does not occur
void PlasmaTvGr::mousePressEvent ( QGraphicsSceneMouseEvent * event )
{

Plasma::Applet::mousePressEvent(event);

Mouse pressed is not really a click -- this would be press release.
However, this is all we have.
that's because there is no defined behaviour for clicking on an applet,
really, unlike say a PushButton where the behaviour is quite well defined and
therefore there is a signal and it does all of the
mousePress/mouseReleaseEvent stuff for you.
this is exactly how it works with QWidget as well, of course.
Applet is a lot more like QWidget than, say, QPushButton

I tried MyApplet::clicked() , but there is no such signal...
I used a mouse click event, wrote my own implementation for that function.
This is not the qt way but no suitable signals are provided. This is what I
did (I am not saying this is a preferred way, simply had no other):
void MyApplet::mousePressEvent ( QGraphicsSceneMouseEvent *ev ) {
if ( signalsBlocked() ) {
Plasma::Applet::mousePressEvent( ev );
return;
}
if ( ev-button() == Qt::LeftButton )
proc_click();
else
Plasma::Applet::mousePressEvent( ev );
}
The first if (I believe) prevents the UI from exercising while the applet is
being moved about.
Right-clicks are handled by the applet's methods, i.e. to place the
context/config menu. There are also hover functions available. No signals.
