QTableWidget column resize event

Question

I want to know whether a column of a QTableWidget is being resized by mouse. How can I emit a signal whenever any of the columns is resized?

Answer 1

Column resizing is performed by the horizontal QHeaderView. Access it by calling QTableWidget::horizontalHeader() const, and the signal you are interested in is QHeaderView::sectionResized(int logicalIndex, int oldSize, int newSize).
