I’d like to implement a widget of two Fixeds in a Vbox, attached to a
TreeView in a HBox.
The top Fixed would be attached to the TreeView’s header, in sense, it’d
allocate the same vertical space. Would show some cairo drawings.
The Bottom Fixed would show some cairo drawings. in a ScrolledWindow,
scrolled by the TreeView’s vertical scroller.
My current problem is: i can’t get the TreeView’s columns’ allocated
height, so i could fixate the height of the top Fixed.
Is it possible?
i tried TreeViewColumn.widget.allocation, but the widget it’s nil, since
it’s not set by me.
I’d welcome anything
