Qt点击QLineEdit弹出系统键盘

参考文章&＃xff1a;Qt5 QLineEdit实现点击调用软键盘

//在需要使用的类中添加关于软键盘的头文件
#include
#pragma comment(lib, "user32.lib")


/* 构造函数中给LineEdit控件添加事件过滤器 */ui->lineEdit1->installEventFilter(this);ui->lineEdit2->installEventFilter(this);//可以写多个


/* 事件过滤器函数重写 */
bool ClassName::eventFilter(QObject *watched, QEvent *event)
{if ( (watched &＃61;&＃61; ui->lineEdit1||watched &＃61;&＃61; ui->lineEdit2) && (event->type() &＃61;&＃61; QEvent::MouseButtonPress) ){callKeyBoard();// 调用软键盘的方法 }return QWidget::eventFilter(watched,event);
}/* 调用软键盘 */
void ClassName::callKeyBoard()
{ PVOID OldValue;BOOL bRet &＃61; Wow64DisableWow64FsRedirection (&OldValue);QString csProcess&＃61;"C:\\Windows\\System32\\osk.exe";QString params&＃61;"";ShellExecute(NULL, L"open", (LPCWSTR)csProcess.utf16(), (LPCWSTR)params.utf16(), NULL, SW_SHOWNORMAL);if ( bRet ){Wow64RevertWow64FsRedirection(OldValue);}
