Flipping of image on QPushButton continuously
Message 1 in thread
Hi,
I need to change an image on PushButton and a TextLabel for 10times
continuously.....
But the image is not changing ..... chk the sample code ......
After the while loop is completed ... it is showing the final image to be
shown .......
I couldnt understand why the image is not flipping.....
n = 10
while(n > 0)
{
pushButton16->setPixmap( QPixmap::fromMimeSource(
"digital_offhook.xbm" ) );
textLabel1->setText( "OFFHOOK" );
sleep(1);
repaint();
}
else
{
pushButton16->setPixmap( QPixmap::fromMimeSource(
"digital_onhook.xbm" ) );
textLabel1->setText( "ONHOOK" );
sleep(1);
repaint();
}
n-- ;
Am i missing something??????
Thanks & Regards,
Hemanth Kumar Nakkina

Because you don't let the Qt event loop run, which does the paintin. Use
a QTimer and a slot to flip the image.
