how to enable buttons when multiple rows are selected in QTableWidget?

[Qqt]

Hello,

I am using QTableWidget in 4.3 to view a table of data, it works fine to select row(s).

Now I want to add a button which is ENABLED when there are multiple rows are selected in the table. I understand I have to pass a bool value to the button.SetEnable(bool), but where can I get this bool value from QTableWidget?

Thanks.

You can use QTableWidget::getSelectedRanges to know how many rows are currently selected.

Thanks for reply.
But when can I check the selected range? I guess there must be a signal I can catch when there are selections in the table, then I can check the selection range there? Can you help again? Thanks.

There is a signal itemSelectionChanged in QTreeWidget, I guess it could be good idea to use it (and read docs as well).

Thank you for the help
