Replace QTreeView::branch using pixmap ?

[SGaist]

Hi,

One possible way is through Qt's stylesheet system.

@SGaist Yes, but how can I pass QPixmap to a widget.setStyle(""" style < pass pixmap?"""); ?

[SGaist]

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.

@SGaist Quite suprising that we can't use QPixmap/QImage in stylesheet I must say... :- ) Looks like I will have to create my pixmap on app start, save to hdd, path to them in style, load style, then delete files.... fun ! :- )

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

[Dariusz]

@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.

@Dariusz @SGaist already suggested a way

@Dariusz
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 ! :)

[Dariusz]

@mrjj Yep its dynamic and user can pick color, in future hell be able to draw his own shapes/icons and all that. But for now its pre-drawn using custom colors.

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

Bummer :- )

@Dariusz
Hi
Ok, fully dynamic.
Ok in that case, the resource file is a no go and
@SGaist advice seems the best option/maybe only option.

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