Re: how to set treeview and drawarea in same position?

[Tristan Van Berkom <vantr touchtunes com>]

this will work:
+----------------------------+
|        GtkWindow           |
| +------------------------+ |
| |   GtkLayout            | |
| | +-------------------+  | |
| | |   GtkTreeView     |  | |
| | |                   |  | |
| | |                   |  | |
| | +-------------------+  | |
| |                        | |
| +------------------------+ |
+----------------------------+
(a treeview in a layout in a window)



this will not work:
+----------------------------+
|        GtkWindow           |
| +---------------+          |
| |   GtkLayout   |          |
| | +-------------------+    |
| | |   GtkTreeView     |    |
| | |                   |    |
| | |                   |    |
| | +-------------------+    |
| |               |          |
| +---------------+          |
+----------------------------+
(a treeview and a layout overlaping 
in a window)




I'm not sure about this
(but I doubt it works):
+--------------------------------+
|       GtkWindow                |
| +----------------------------+ |
| |        GtkLayout           | |
| | +---------------+          | |
| | |GtkDrawingArea |          | |
| | | +-------------------+    | |
| | | |   GtkTreeView     |    | |
| | | |                   |    | |
| | | |                   |    | |
| | | +-------------------+    | |
| | |               |          | |
| | +---------------+          | |
| +----------------------------+ |

I hope this helps,
