QTableWidget列调整大小事件 [英] QTableWidget column resize event

问题描述

我想知道QTableWidget的列是否正在通过鼠标调整大小.每当调整任何列的大小时如何发出信号?

解决方案

列的大小调整由水平的 QHeaderView 执行.通过调用 QTableWidget :: horizo​​ntalHeader()const 对其进行访问，而您感兴趣的信号是 QHeaderView :: sectionResized(int logicalIndex，int oldSize，int newSize)./p>

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?

解决方案

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).
