我在Windows下用Qt做一个登录界面，怎么把密码（QlineEdit)输入框的鼠标右键给屏蔽了？
bool Dialog_register::eventFilter(QObject *target, QEvent *event)
{
if(event->type()==QEvent::MouseButtonPress)
{
QMouseEvent *event1 = static_cast<QMouseEvent*>(event);
if (event1->button()==Qt::RightButton)
{
qDebug("Ate MouseButtonPress %d", event1->button());
return true;
}
}
if(event->type()==QEvent::MouseButtonRelease)
{
QMouseEvent *event1 = static_cast<QMouseEvent*>(event);
if (event1->button()==Qt::RightButton)
{
qDebug("Ate MouseButtonPress %d", event1->button());
return true;
}
}

前面加个判断
if(event->button()==Qt::LeftButton)
之后再执行你的那些操作，这样就只左键管用了
