Qt：如何从主窗口中删除默认的主工具栏？ [英] Qt: How to remove the default main toolbar from the mainwindow?

问题描述

我是新的Qt，我不知道为什么在我的主窗口中有一个可拖动对象。

I am new to Qt, and I can't figure out why there is a draggable object in my main window. It starts at the top of the screen in its exapanded form.

然后我可以拖动它并缩小成一个正方形。

And then I can drag it and it shrinks into a square.

推荐答案

您需要从下面的代码中手动删除QtDesigner中的主工具栏：

You need to remove the main toolbar from either QtDesigner as can be seen below or from the code manually:

然后，您需要重新运行qmake进行更改效果，因为 ui_mainwindow.h 头文件需要从更新的 mainwindow.ui 描述文件重新生成。

Then, you will need to rerun qmake for the changes to take effect as the ui_mainwindow.h header file needs to be regenerated from the updated mainwindow.ui description file.
