Vertical Scroll bar with QtableWidget

Question

This problem is observed in Mac only. In Winows 7 and XP, everything works fine.

In QTable Widget, I am adding some items in certain columns using setCellWidget(). Whereas, to add items in other columns of the same row I am using setItem(). When I tried to use vertical scroll bar, the items added by using setItem() scroll properly. But the items added by setCellWidget() do not scroll at all . They are frozen. What I tried – [1] I tried setting the stylesheet – QString scrollStyleSheet = “QTableWidget {}”; // tried few variations too , but this works the best ui->deviceGridTable->setStyleSheet(scrollStyleSheet );

It works fine, so long as I do not scroll, when items are getting added. Before adding new items or after adding new items, if I scroll, it works fine. However, if I scroll, while new iterms are being added one by one , it shows the same old ugly characterstics which I just described.

[2] I tried setting VerticalScrollMode to ScrollPerPixel. It does not work at all.

What else can I try to fix the problem of vertical scrolling while items are detting added ? (Only for those items which are added using setCellWidget().

The problem is only on Mac OSX 10.8.1. I am using Qt 4.8.3

Try this:

tableWidget.setVisible(0)
tableWidget.setSortingEnabled(0)
... populate tableWidget here ...
tableWidget.setSortingEnabled(1)
tableWidget.setVisible(1)

If you do not use sorting then try only with visibility.
