Line crossing widgets
-
Hello all,
Here is my issue. I have a QTreeWidget with widgets as children something like this :
|>Parent
Child Widget1
Child Widget2
Child Widget3|>Parent2
Child Widget1
Child Widget2
Child Widget3etc, ... These children widgets contain some graphics like a rectangle (XXXXXX here)
so, it looks like that :
|>Parent
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX|>Parent2
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXI need a vertical line to cross all this TreeWidget and the children widgets, something like that :
|>Parent
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXX|>Parent2
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXX
XXXXXXXXXXXX | XXXXXXXXXXXXXXXXXXXXXXXI have no idea how to achieve that. Does anybody have an idea? That would be very helpful.

Hmmm,
seems like You will need to subclass "QItemDelegate":http://qt-project.org/doc/qt-4.8/qitemdelegate.html to achieve this. Here You have an example how to sublass and use it: "Star delegate example.":http://harmattan-dev.nokia.com/docs/platform-api-reference/xml/daily-docs/libqt4/itemviews-stardelegate.html .
Maybe You will also need to show Your children data in 2 columns? To achieve this Your model's "columnCount":http://qt-project.org/doc/qt-5.0/qtcore/qabstractitemmodel.html#columnCount should return 2 and Your "data":http://qt-project.org/doc/qt-5.0/qtcore/ qabstractitemmodel.html#data method should return proper content.
I hope this will help. In case of any doubts just ask here :).

Hello Bob,
Thannks for your help.
I dont want to split the widget, I just want to draw a QGraphicsItem (here the line) on the widget.
I was able to draw a simple QlineF line on the widget by reimplementing paintEvent() on the widget but this doesn't look to work for a QGraphicsItem...
