[Qt-interest] Is there an event for when you try to click outside an active modal dialog?

[John Eke]

Hi,

Imagine a QMessageBox displaying an error message, if you try to click elsewhere on the parent application, the messagebox flashes, to show that it must first be closed before you can perform other operations.

Is there a way to trap that flash? Is there an event sent somewhere when the dialog is flashing?

As long as you operate on an int at a time instead of a char at a time, 
and use shift operators and bit masks to manipulate the pixel's color 
channels, your code should be endian-independent.
