Re: GtkTreeView cursor focus

[Stefan Kost <ensonic hora-obscura de>]

Hi Jonathan,

hmm, I've understand your point. Here are some more details:

a.)
first colum: cell-renderer-text with mode=GTK_CELL_RENDERER_MODE_INERT
other columns : cell-renderer-text with 
mode=GTK_CELL_RENDERER_MODE_ACTIVATABLE:
I don't get this rectange, but the cell-focus is nearly invisible (it is 
a dotted thin frame).

b.)
first colum: cell-renderer-text with mode=GTK_CELL_RENDERER_MODE_INERT
other columns : cell-renderer-text with mode=NULL
I get the row rectangle, I still can navigate left-right, but there is 
no visual indication of in which column I am.

What I am looking for is:
a.) moving the cursor around in activatable cells
b.) selecting rectangular areas

For b) I will look at gtk_tree_selection_set_select_function() ...

Ciao
 Stefan
