自定义Qt QMenu [英] Custom Qt QMenu

问题描述

Qt中是否可以将布局或小部件添加到QMenu中以创建自定义菜单?

Is there a way in Qt to add a layout or widgets to a QMenu to create a custom menu?

下面的示例(左)就是我所拥有的，我想通过添加非菜单窗口小部件来实现类似于右侧模型的目的.如果QMenu无法做到这一点，是否有指南可以在任何地方产生类似的结果(也许通过使标准的小部件充当上下文菜单)?

The example below (left) is what I have, and I'd like to aim for something similar to the mock-up on the right, by adding non-menu widgets. If it can't be done by QMenu, are there guides to produce similar results (perhaps by having a more standard widget act as a context menu) anywhere?

推荐答案

当然可以！在Qt中，如果有一个意志，那就有一种方法.

Sure there is! In Qt, if there is a a will there is a way.

您可能需要创建自己的使用QMenu并使用成员QListWidget的类.

You will probably need to make your own class that uses QMenu and uses a member QListWidget.

然后，您将需要生成布局并重载所有正确的QLayout函数以进行尺寸重新计算.

You will then need to generate the layout and overload all the correct QLayout functions for size recalculation.

然后您需要使用此布局(请考虑QHBoxLayout)来同时显示QMenu和QListWidget.

And then you'll need to use this layout (think QHBoxLayout) to display both a QMenu and a QListWidget side by side.

这足以使您指向正确的方向.

That should be enough to point you in the right direction.

正如评论者所指出的，您不能继承两个QObject内容，因此我更新了 相应地回答.

As a commenter pointed out, you can't inherit two QObject things so I updated the answer accordingly.
