软键盘，在Windows系统上叫屏幕键盘。前一句只是为了让更多的人通过搜索引擎搜到我的文章。对于实现软键盘，我在网上查找了2、3天。发现用Qt实现并不好缺点很多，所以最终选择用Windows API实现。对此我想说以下几点：
- 最好不要用Qt的QApplication::sendEvent或QApplication::postEvent，它们的限制很多。据我粗略测试，它们只对本程序有效。换其它应用程序会影响其它程序的输入焦点，并且不能发送键盘事件。
- 获取输入焦点窗口不能用GetForegroundWindow，它获取的是前台主窗口的句柄，并不是窗口内的编辑框句柄。GetFocus也不行。只能用GetGUIThreadInfo获取输入焦点控件句柄。
- 模拟按键不要用SendMessage或PostMessage，这俩确实能发送按键消息，但是不支持输入法。根据我的测试连组合键（比如发送Shift+A，模拟输入大写的A）都模拟不了。要使用SendInput模拟发送按键消息，这个能发组合键，也支持输入法。该函数取代了旧的keybd_event函数。
- Windows系统的窗口风格WS_EX_NOACTIVATE是相对于其它exe而言的，不会夺取其它程序窗口的焦点。如果另一个窗口跟它在同一个进程内，点击它同样会夺取焦点。
附：
- SendMessage或PostMessage模拟发送KeyDown、KeyUp消息参考文件：https://learn.microsoft.com/zh-cn/windows/win32/inputdev/wm-keyup
- SendInput函数的参考文件：https://learn.microsoft.com/zh-cn/windows/win32/api/winuser/nf-winuser-sendinput
下面是程序的效果图。界面没有美化，直接用QPushButton做的按钮。读者如果需要可以自己去美化，比如使用qss样式表。我的审美不行而且对qss也不熟悉，做不了漂亮的界面：
上代码，头文件：
class MSoftKeyboard : public QWidget { Q_OBJECT public: MSoftKeyboard(QWidget *parent = Q_NULLPTR); ~MSoftKeyboard() = default; private slots: void buttonClicked(); private: void sendKeyEvent(HWND hWnd, QObject* button); void switchCases(); void initKeyMappingWin(); HWND findFocusWindow(); struct KeyMap { QPushButton* uiCtl; int qtEnum1; /* 小写字母虚拟键盘码 */ int qtEnum2; /* 大写字母虚拟键盘码 */ bool capsSwitch; bool shiftSwitch; QString lowCase; /* 小写字母 */ QString upperCase; /* 大写字母 */ }; private: Ui::MSoftKeyboard ui; QVector<KeyMap> keyMapping; bool capslock; bool shift; };
