I have a small application that needs to update GUI elements if some event occurs in lower levels, say, socket goes off-line, or something like that.
In Windows, I could use PostMessage which would be sent through the chain to all Windows, and the required ones could update accordingly.
How can I achieve something similar in wxWidgets? I cannot use OnUpdateUI, or something like that, because some controls doesn't seem to handle that at all.
The target window could be one or multiple, they could be frames or controls, so I'm confused a little here.
Does anyone have a suggestion?
