在子菜单qt中创建滚动条? [英] create a scrollbar in a submenu qt?

问题描述

我有一个地图应用程序和一个子菜单，根据加载的图层，该子菜单已将动态添加的对象(即地图上的点)添加到该子菜单中.我可以通过单击相应的子菜单项来隐藏每个单独的对象(即一个点).有什么组织子菜单的方法吗?当有很多点(即100)时，整个子菜单将占据屏幕.我可以在子菜单中添加滚动条吗?我查看了文档，但找不到支持此功能的任何东西.

I have a map application and a submenu which has dynamically added objects (i.e. points on a map) added to the submenu, depending on the layer that is loaded. I have the ability to hide each individual objects (i.e. a point) by clicking on the corresponding submenu item. Is there any way to organize the submenu? When there are a lot of points (i.e. 100) the entire submenu takes up the screen. Can I add a scrollbar to a submenu? I looked in the documentation, but couldn't find anything that support this feature.

推荐答案

来自此错误报告我发现您可以执行以下操作:

From this bug report I was able to find out that you could do the following:

submenu->setStyleSheet("QMenu { menu-scrollable: 1; }");

像魅力一样工作.
