Hello all
As we all know that in a treeview, rows can be added in hierarchy. To
expand, there are small triangles (arrows) clicking any of which the
row expands/collapses.
If I wish to customise these arrows for my application and use some
different icons as expander arrows, how can it be done?
Thanks in advance.
I don't think it's possible. I looked at the gtk+ source code. As far as
I can see, those triangles are hard-coded. They are drawn with a few
cairo functions (cairo_move_to(), cairo_line_to(), cairo_fill(), etc.)
