- Bug: In NetlistWidget/NetlistModel, suppress the "forceRowHeight()"
method which was terribly slowing down the table display. Instead
uses the "setDefaultSectionSize()" of the vertical header to setup
the row height (much more compact display).
- Bug: In NetlistModel, strangely, although we have a "data()" and a
"headerData()" method, the "data()" is also called for the headers
potentially erasing any previous setting done with "headerData()".
This was occuring for the fonts settings. Don't known if it is
a bug or a feature of Qt...
- Thoses changes has to be ported to the others widgets some times...
