Pump Messages

[Сергей Коныгин]

Hi!

I have a code that requires very long time. Every iteration I do "pump messages" (for Cancel button). But this code doesn't work on Linux. Can I do it by wxWidgets?

// piece of code

for( int i=0; i<10000; i++ )

{

    // doing something

    DoCalc();

    // pump messages in Windows

    MSG msg;
    while( PeekMessage( &msg, NULL, 0, 0, PM_REMOVE ))
    {
        TranslateMessage( &msg );
        DispatchMessage( &msg );
    }

   // check for cancel button

   if( mbCancel ) break;

}

Yes, see wxEventLoop class or use wxYield(). But you really shouldn't,
it's a very bad idea to do it like this, so you should rather use porting
to Linux as an opportunity to rewrite your code in a better way.
