如何使 Qt Widget 随着窗口大小而增长? [英] How to make a Qt Widget grow with the window size?

问题描述

我想要一个小的 QFormLayout 来填充它的父小部件.

I want to have a small QFormLayout that grows to fill its parent widget.

我使用 Qt Designer 中的 QWidget 模板创建了一个新的 .ui 文件.我在那个窗口"里面放了一个 QFormLayout，然后在那个 QFormLayout 里面放了一些控件.

I created a new .ui file using the QWidget template in Qt Designer. I put a QFormLayout inside that 'window', then put some controls inside that QFormLayout.

这一切都运行得相当好，但 QFormLayout 始终保持我在 Qt 设计器中设置的大小.我希望 QFormLayout 填充它的父小部件并用它增长/缩小.

This all works reasonably well, but the QFormLayout always stays at the size I set in Qt Designer. I would like the QFormLayout to fill its parent widget and grow/shrink with it.

我怎样才能做到这一点?

How can I accomplish that?

推荐答案

在 Designer 中，激活 centralWidget 并分配布局，例如水平或垂直布局.然后你的 QFormLayout 会自动调整大小.

In Designer, activate the centralWidget and assign a layout, e.g. horizontal or vertical layout. Then your QFormLayout will automatically resize.

始终确保所有小部件都有布局！否则，自动调整大小将与该小部件中断！

Always make sure, that all widgets have a layout! Otherwise, automatic resizing will break with that widget!

控件坚持过大，并且不会在 QtDesigner 中调整大小
