Qt:带有关闭、最小化和帮助按钮的 QMainWindow [英] Qt: QMainWindow with a close, minimize and help button
问题描述
如果我有一个继承 QMainWindow 的类，并且我希望它只有按钮；在窗口栏中关闭、最小化和帮助，我应该如何进行?
If I have a class which inherits QMainWindow, and I want it to only have the buttons; close, minimize and help in the window bar, how should I proceed?
如果我将此代码用于窗口标志:setWindowFlags(Qt::Window | Qt::WindowContextHelpButtonHint | Qt::WindowMinimizeButtonHint);它会生成一个带有最大化、最小化和关闭按钮的窗口.
If I use this code for the window flags:
setWindowFlags(Qt::Window | Qt::WindowContextHelpButtonHint | Qt::WindowMinimizeButtonHint);
It results in a window with maximize, minimize and close button.
如果排除WindowMinimizeButtonHint"，则只有帮助和关闭按钮.
If I exclude "WindowMinimizeButtonHint", there is only a help and close button.
如果可能，我怎样才能使只有关闭、帮助和最小化按钮?
How can I, if possible, make so there is a close, help AND minimize button ONLY?
