Colin's const-fixing Patch Of Death. Seems to build fine on Windows
[u/mdw/putty] / unix / gtkdlg.c
1 /*
2 * gtkdlg.c - GTK implementation of the PuTTY configuration box.
3 */
4
5 /*
6 * TODO when porting to GTK 2.0:
7 *
8 * - GtkTree is apparently deprecated and we should switch to
9 * GtkTreeView instead.
10 * - GtkLabel has a built-in mnemonic scheme, so we should at
11 * least consider switching to that from the current adhockery.
