如何使用鼠标使用Qt更改网格布局单元的大小? [英] How to using mouse to change size of grid layout cells using Qt?

问题描述

我使用网格布局(水平和垂直).我喜欢这样的事实，即调整窗口大小时会填满整个窗口内容.但是此扩展程序管理不善.我经常想更改网格布局中仅一列的大小，而不更改窗口的大小.例如在Windows资源管理器中.有两列-目录的左侧列表及其内容在左侧的右边.而且我总是可以在它们之间按下鼠标按钮，并拖动以更改列之间的相互大小.

I use grid layout (horizontal and vertical too). I like the fact that when resizing the window fills the entire window contents. but this extension is poorly managed. I often want to change the size of only one column in grid layout without changing the size of the window. such as in Windows Explorer. there are two columns - the left list of directories and their contents to the left to the right. and i can always press mouse button therebetween and pulling change the mutual sizes of columns in relation to each other.

如何在Qt中做到这一点?

how can I do this in Qt?

推荐答案

您需要使用 QGridLayout 情况(您只想将2个小部件一起显示). QSplitter可拖动.

You need to use a QSplitter rather than a QGridLayout in this specific case (where you just want 2 widgets shown together). QSplitters are draggable.
