Re: getting the height of all cells in treeview

[Stefan Kost <ensonic hora-obscura de>]

Please help, I am now totaly lost in the API.

I've now converted all my code to use the fixed-height mode.
The biggest disadvantage is that I now need to set 'fixed-width' for each column.
  gtk_tree_view_columns_autosize()
shows no effect (its called after realizing the treeview).

First question: When I set, fixed-height mode, why to I need to to use the FIXED 
sizing for tree_view_columns? To me that is not related.

Second question: Even now that I am using a fixed size, its not much easier to 
find out how big my treeview rect is. I am using a filtered model. And thus I 
would need to manually walk over the rows, check if they are visible and 
multiply that with the height determined by gtk_tree_view_get_background_area() 
for e.g. the first row. - A bit much to do in an expose_event().

Come one, there surely is a better way. And can't imagine I am the first who is 
trying this.
