-

i have multi threaded wxpython app , main gui thread receives notification other threads show under modal dialog box. want kind of scheduling/queuing dialog should appear 1 after other if multiple notification (from other threads) comes @ same time.

as each notification arrives add queue, (i.e. list), , each dialog closed remove notification queue , if not empty show next - and listen users complain.

n.b. careful not situation spotted few times clicking on dismiss button caused notification. classic case error window reporting many error windows open.
