QT 4.5 - Changing the selection marquee for QGraphicsItem
-
05-07-2019 - |
Question
Is it possible to define the style of the selection marquee when a QGraphicsItem is set selectd via setSelected(true)?
Solution
Technically no.
After a quick look into Qt's source code, it seems that the standard item types QGraphics*Item have the dashed outline as a default behavior. You can work around this by subclassing your own QGraphicsItem.
if (option->state & (QStyle::State_Selected | QStyle::State_HasFocus))
qt_graphicsItem_highlightSelected(this, painter, option);
I guess you can not change the "style". This seems to be a very static feature of the standard QGraphicsItems.
Hope that helps!
