如何使Widget或Dialog在Qt中不可移动 [英] how to make Widget or Dialog not movable in Qt

问题描述

Plz有人帮我找到这个..

解决方案

我认为你可以通过重写 mouseMoveEvent（QMouseEvent * event）。

来自文档：

 mouseMoveEvent（）处理鼠标移动事件。默认情况下，仅当用户按住按钮时才会生成这些事件。可以通过调用QWidget :: setMouseTracking（）

来改变这种行为。首先，看看这个，它没有回答你的问题，但是提供一些信息。



http： //qt-project.org/doc/qt-4.8/application-windows.html#window-geometry [ ^ ]



虽然我从未这样做过，你可能需要编写自己的类（子类是感兴趣的类），然后覆盖move方法（或者是一个插槽）。是的，它是一个在移动类时调用的方法。我没有检查源，但是，我希望给定移动（x，y）和移动（点），一个调用另一个，但我没有验证这一点。我只是在猜测。



如果你知道这只会用鼠标（而不是键盘）移动，setMouseTracking可能有所帮助，但我没有以任何方式看待它。

Plz some one help me to find this..

解决方案

I think you can subclass QWidget by overriding mouseMoveEvent(QMouseEvent *event).
From documentation:

The mouseMoveEvent() handles "mouse move" events. By default, these events are only generated when the user is holding down a button. It is possible to change this behavior by calling QWidget::setMouseTracking()

First, take a look at this, which does not answer your question, but does provide some information.

http://qt-project.org/doc/qt-4.8/application-windows.html#window-geometry[^]

ALthough I have never done this, you may need to write your own class (sub-class the class of interest) and then over-ride the move method (or is that a slot). Yes, it is a method that is called when the class is moved. I did not check the source, but, I expect that given move(x, y) and move(point), one calls the other, but I did not verify this. I am only guessing.

If you know that this will only be moved using the mouse (and not the keyboard), setMouseTracking may help, but I did not look at that in any way.
