重写QLineEdit类，在派生类中重写keyPressEvent和keyReleaseEvent函数，可以屏蔽键盘输入(包括搜狗输入法的中文输入问题)。void RbtLineEdit::keyReleaseEvent(QKeyEvent *event){ if (event->key() == Qt::Key_Shift) { setText(content); } }void RbtLineEdit::keyPressEvent(QKeyEvent *event){

border-style: outset; border-width: 2px; border-color: green;效果：

1.重写QLineEdit类，在派生类中重写focusInEvent方法。缺点:输入光标也会消失，需要在重写光标显示。2.在主窗口增加事件过滤bool ShortKeySetWidget::eventFilter(QObject *watched, QEvent *event){ if (watched->objectName() == "m_lineEdit") { if (event->type() == QEvent::FocusIn) { this->

QPixmap clearPix = QPixmap();sourcepx = clearPix;

当QWidget为模态的时候，用QSS （border-radius:6px;）设置圆角窗口时，会有直角阴影。后采用QBitmap类填充实现圆角窗口。{ QBitmap bmp(this->size()); bmp.fill(); QPainter painter(&bmp); painter.setPen(Qt::NoPen); painter.setBrush(Qt::black); painter.setRenderHint(QPainter::Antiali
