Hey, I've got a couple of questions all somehow related to gtk.TreeViews.
1. I'm looking for a way to replace the expander icon in a gtk.TreeView. I've spent countless hours searching stackoverflow, the mailing list, the pygtk docs, pydoc and simple trial-and-error without any success. The only slightly relevant thing I found was FAQ entry (13.14) where a CellRendererPixbuf is added to a gtk.TreeViewColumn and its "pixbuf-expander-closed" property is set accordingly. This however just adds an image next to the expander which changes based on the state of the exander. I'm looking for a way to replace the expander itself.
2. On a related note, how would I go about changing the color of grid lines in a treeview? I'd like to change this programatically, not with a new entry in my gtrc file since I'd like it theme-independent.
3. Lastly, is there a way to change the effective area of a row in a treeview? To elaborate on this question, I have a treeview with a single column where I show a filesystem hierarchy based on a gtk.TreeStore. I changed the colors of the treeview with a subclassed gtk.GenericCellRenderer so that selected rows aren't highlighted completely, but rather just the text in the currently selected row has a colored background. Naturally, however, the default behaviour of the CellRenderer is still intact which means a row is selected when I click anywhere in the row, not just on the text. I'd like to change the area which reacts to mouseclicks to the area of the text in the row. I thought about using the "clicked" signal of the treeviewcolumn to determine the position of the click and do some geometric checks whether the click position was atop a row in the treeview, but the information doesn't seem to be passed on.
I'm really struggling with these things. They seem to be somewhat straight-forward changes (except for the last one maybe), but I can't for the life of me find a solution.
Help is really appreciated. Cheers, Klaus _______________________________________________ pygtk mailing list [email protected] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
