Hey
I did some drawing in my qt app and I would like to use them as a QTreeView branch for my qtree view. How can I set branch to use my pixmap?
TIA.

Hi,
One possible way is through Qt's stylesheet system.

I currently don't know if it's possible to have them inline in the style sheet. I would guess using base64 encoding but that's really only that, a guess. What you can do is to save your drawings as .png files in a suitable folder provided by QStandardPaths and then use them in the style sheet.

Hi
Well you can use images from a resource file which is super handy.
Then you need zero code to have them at funtime and you can ref them directly in style sheet -

@mrjj How can I add images to resources at runtime? I want to change the branch indicator to have the color that user wishes to do here.

Hi
Ok so it has to be 100% dynamical
so you create the actual pixmap runtime? it can be any color ?
Else you can just have the various versions in the resource file.You dont add anything to the resource file at runtime as its compiled into the exe ! :)

As far as I can tell I have to save to hdd and load it up via stylesheet & path...
Bummer :- )

Then maybe QTreeView::drawBranches is what you are looking for.
