QTableWidget::setCellWidget and size

[tuli]

I have a separate widget consisting of a QTextEdit and a few buttons. The QTextEdit has a preferred size and grows as the widget is resized. All of this works fine.

however, when i want to set this widget into the cell of a QTableWidget, using tw->setCellWidget(a,b,mywid), then my widget is much bigger than its preferred size.

for(...rows...)
   for(...cells...)
      tablewidget->setCellWidget(row, cell, new mywid());
 
tablewid->resizeColumnsToContents();
tablewid->resizeRowsToContents();

for(...rows...)
   for(...cells...)
      tablewidget->setCellWidget(row, cell, new mywid());

tablewid->resizeColumnsToContents();
tablewid->resizeRowsToContents();

To copy to clipboard, switch view to plain text mode 

I can then proceed to manually resize the column width, which shrinks my widget accordingly.
The question is, why doesnt setCellWidget() respect my wished size?


mywidget->show()

pops up the widget, sized correctly.

edit:
no, i was wrong: sizeHint() returns an incorrect size! Why is that? Why is it show()n sized correctly?
