将小部件放置在QScrollArea的中心 [英] Place widget in center of QScrollArea

问题描述

如何将尺寸固定的自定义小部件放置在QScrollArea的中心?

How can I place custom widget with fixed size in center of QScrollArea?

我可以使用myWidget.pos(x，y)将小部件手动放置在QScrollArea内，但是QScrollArea中没有sizeChanged信号，因此如果滚动区域更改，此位置将是错误的.

I can place the widget manually inside QScrollArea with myWidget.pos(x,y) but there is no sizeChanged signal in QScrollArea so this position will be wrong if scroll area changed.

推荐答案

我使用@thuga的建议来设置对齐方式，但是我还必须为小部件设置一个固定的大小(在此之前，我仅设置了最小大小)，而且我还需要使用水平布局而不是垂直布局.由于某些原因，垂直布局会忽略滚动区域的水平对齐方式.

I used @thuga's suggestion to set the alignment, but additionally I had to set a fixed size for the widget (I was settings only the minimum size before that), and also I needed to use a horizontal layout instead of a vertical one. For some reason, the vertical layout disregards the scroll area's horizontal alignment.

我使用 setFixedSize()为自定义窗口小部件设置了固定大小，但是可以从Qt Designer中设置布局和对齐方式.

I used setFixedSize() to set a fixed size for my custom widget, but the layout and the alignment can be set from Qt Designer.
