They are drawn with a few cairo functions (cairo_move_to(), cairo_line_to(), cairo_fill(), etc.)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. Kjell |
