Qt C ++最小化和最大化窗口

Question

I create main window by using class QWidget and setup window flag to Qt::CustomizeWindowHint (to disable title bar). But than I found problem - when I click on my program button on Windows taskbar - program won't minimize and maximize. What can I do to remove this problem? I use Windows 7. Sorry 4 my bad english.

Answer 1

这是Qt :: CustomizeWindowHint的功能。当使用这个windows标志时，你很难控制窗口。你可以尝试的是在窗口中添加两个按钮并将它们连接到showMaximized（）和showMinimized（） 。然后你可以最大化或者单击按钮最小化窗口。

Answer 2

This answer is a while ago but I faced the same challenge now and could find a solution. Maybe its helpfull for someone else. As proposed before one should specify Qt::FramelessWindowHint instead of Qt::CustomizeWindowHint . This also hides the title and border of the window. To still have the minimize/maximize feature I additionaly specified Qt::WindowSystemMenuHint , Qt::WindowMinimizeButtonHint and Qt::WindowMaximizeButtonHint . That's it!
