**patrik08** · 8th March 2007, 12:47

I want to display a button on my table ....

how i must set paint ?... to display direct QWidget ... not only on click.....

if (index.column() == 0) {
int xnummer = index.model()->data(index, Qt:

isplayRole).toInt();
this->createEditor(tas, option, index);

}

Qt Code:

Switch view

  tas = ta;

Either use setIndexWidget or openPersistentEditor.

Just please don't paste so much unrelevant code in your posts (like in the first post in this thread). Nobody will read it anyway, so there is no point posting it. If you want to include some code, then make it as short (and simple) as possible.
