Using Python 3.10, GTK 4.6.4
I’m porting a large GTK3 application to GTK4, nearing the end, but have just hit a snag. I’ve hit a TreeView
that has expandable/collapsible children rows (i.e. the TreeStore
iter has child iters). The TreeView
uses some custom CellRenderers
that crash spectacularly in GTK4, so I need to convert this to a ColumnView
.
I have never attempted a ColumnView
that has expandable child rows – is that possible, and would anyone be so kind as to explain how, or point me to some documentation or examples?
