good day all,
I'm currently writing a Plasmoid for KDE, so I'm not 100% certain who's lap to
lay this in, but I'll try here first.
I'm using a Plasma.Frame which inherits a QGraphicsWidget, in my subclass I
have reimplemented the itemChange function so I can set the element prefix of
the SVG used to paint the frame.
when i press each item with the left mouse button, everything works as
expected :)
however if i right click an item, its ElementPrefix changes ok and the menu
pops up, but the other item that is selected doesn't deselect. and i end up
with 2 selected items until i click one again.
Martin
here is a snippet of the code...
def itemChange(self, change, value):
if change == QGraphicsItem.ItemSelectedChange:
print "selection changed"
if value == QVariant(True):
self.border.setElementPrefix("selected")
else:
self.border.setElementPrefix("normal")
self.update()
return value
def mousePressEvent(self, event):
if event.button() == 1:
self.setSelected(1)
self.update()
if event.button() == 2:
self.setSelected(1)
self.update()
self.menu.exec_(QCursor.pos())
