Qt4:使全屏窗口无法绕开(锁定屏幕)? [英] Qt4: Making fullscreen window impossible to get around (a lock screen)?

问题描述

我的应用程序是一个操作系统锁定屏幕(例如GDM的锁定屏幕或KDE的锁定屏幕)，所以我试图使其功能像一个.

My application is an OS lock screen (like GDM's lock screen or KDE's), so I'm trying to make it function like one.

我试图将应用程序的窗口悬停在所有所有窗口上方，并禁用/拦截所有键盘快捷键( ALT-TAB ， CTRL-ALT-D等)，导致它消失.

I am trying to make my application's window hover above all other windows and disable/intercept all keyboard shortcuts (ALT-TAB, CTRL-ALT-D, etc.) that would cause it disappear.

有没有办法做到这一点?我有100％的肯定，因为存在带有GUI的锁屏，但我只是找不到寻找的地方...

Is there any way to do this? I'm 100% sure there is, as lock screens with GUIs exist, but I just can't find the place to look...

推荐答案

我不知道如何使用Qt进行操作，但是您正在寻找的被称为指针输入设备和键盘.

I don't know how to do it with Qt, but what you are looking for is called grabbing. You can grab the pointer input device as well as the keyboard.

:查看Qt4文档，您是否尝试过使用 QWidget :: grabMouse ?看起来此功能完全可以满足您的要求.

Looking in to the Qt4 docs, have you tried to use QWidget::grabMouse? It looks like this function does exactly what you want.
