Hi,

Is your table widget standalone ? If so are you sure the path to the icon is correct ? You can check with isNull()

Hope it helps

i have actions in my main window.
one of the actions activates a function which creates this table widget.
but only my mainwindow has icon and not this tablewidget that pops up.

how to add icon to this widget

Just realized something. You don't call setWindowIcon on your QTableWidget but on the containing widget

ill try that asap

It was a mistake on my part actually.
i changed
@setWindowIcon(icon);@
to
@table->setWindowIcon(icon);@

and it worked;

thank you for your help
