Hi
Make the pixmap bigger, then it will have a higher resolution.
You also have to call resize on the table view to make it use the new size.
If the table view is in a layout this is not so easy as we cant resize it then.Can I ask what the issue is ? you render the GUI to pixmaps and they are blurry when you print them or
why you need higher res ? -
Hi,
AFAIR, the rendering resolution of a widget is tied to its size.
What kind of high resolution do you have in mind ?
