Question

I have several qdockwidget and within these a qtableview, as seen in the attached picture, my problem is I want the tables are the same size of the dock.

I tried to do this and it does not work:

table-> resize (dock-> size());

By default, the cells in a table do not expand to fill the available
space. You can make the cells fill the available space by stretching
the last header section. Access the relevant header using
horizontalHeader() or verticalHeader() and set the header’s
stretchLastSection property.

I hope that helps you. Cheers.
