将小部件尺寸设置为其他尺寸的一半

Question

In Qt, I have a QDialog with two QTreeView objects. I want one of them to always be half the height of the other one, and maintain this when I resize my dialog. I add the in a QVBoxLayout .

How can I do this?

Answer 1

You can use the QVBoxLayout::addWidget() method's stretch argument, like this:

layout->addWidget(smallWidget, 1);
layout->addWidget(bigWidget,   2);
