Re: OnIdle() alternatives
I am using a derivative of OnIdle() in the CWinApp class to service a
series of multi-threaded CEvent/CMutex controlled data queues. However,
whenever a modal dialog pops up or a menu item is selected or even a
scroll bar is used the OnIdle() stops being called.
Even if I use a WM_TIMER event instead to crank the servicing it does
not always get through. And WM_KICKIDLE doesn't seem to be too reliable
Can anyone recommend a better way to service these multi-threaded
events so that general Windows GUI actions don't interfere with it?
Many thanks in advance!
If you must process the events & queues in the GUI thread then your best
bet is probably a user-defined message posted to the main window. (Use
ON_MESSAGE in the message map.) I've never seen these fail to get
serviced and they have higher message queue priority than OnIdle,
OnTimer and OnPaint.
