[Gtk-sharp-list] Weird behavior in CellRendererToggle ...
Thu, 16 Oct 2003 04:37:58 -0400 (EDT)
The following happened to me:
Invalid values of a CellRendererToggle of a TreeViewColumn are not catched
at compile time resulting in invisible CheckButtons in the intanced
I was porting tree_store.c to gtk#.
In the tree_store.c a column is inserted with
col_offset = gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW
Where the enums ALEX_COLUMN = 1, VISISBLE_COLUMN = 6 and WORLD_COLUMN =7
wich I (stupidly ported as)
Column = new TreeViewColumn("Alex", rendererToggle,
The result compiles find but the checkBoxes are invisible :-(
After thinking about what I was coding I wrote code that works kind of
better but is not perfect:
column = new TreeViewColumn("Alex", rendererToggle,
column.Visible = true;
rendererToggle.Activatable = true;
rendererToggle.Active = true;
This last statement worked the "best" but it seems stupid since I'm using
the active signal twice.
The check boxes are now visible. :-)
What is the right way of handling this ?
Can the TreeViewColumn constructor handle several arguments ?
You can get the unifinished and ugly code of GtkDemo at
to play arround.
