How to update QLable setGeometry(x,y,width,height) x,y positions in QT based on mouse x,y coordinates, with existing QLable name only.
-
Hi Team, I've added QLabel dynamically. And when I move the mouse, I want to get that dynamically added QLabel name, and update its setGeometry() x,y positions with the mouse pointer x,y positions
void MainWindow::boxClicked()
{if(Cb_Mag->isChecked()) { QLabel *my_label = new QLabel(this); QRect crop_rect(200, 500, 250, 250); QImage desk = qApp->screens().at(0)->grabWindow( QDesktopWidget().winId(), crop_rect.left(), crop_rect.top(), crop_rect.width(), crop_rect.height()).toImage(); my_label->show(); my_label->setPixmap(QPixmap::fromImage(desk)); my_label->setStyleSheet("border:5px solid grey"); my_label->setGeometry(200, 500, 250, 250); }}
void MainWindow::mouseMoveEvent(QMouseEvent *mMoveEvent)
{delete this->findChild<QLabel*>("my_label"); QLabel* my_label = new QLabel(this); my_label->setObjectName("my_label"); QRect crop_rect(mMoveEvent->pos().x(), mMoveEvent->pos().y(), 500, 250); QImage desk = qApp->screens().at(0)->grabWindow( QDesktopWidget().winId(), crop_rect.left(), crop_rect.top(), crop_rect.width(), crop_rect.height()).toImage(); my_label->show(); my_label->setPixmap(QPixmap::fromImage(desk)); my_label->setStyleSheet("border:10px solid grey;border-radius: 16px;"); my_label->setGeometry(mMoveEvent->pos().x(), mMoveEvent->pos().y(), 500, 250);}
In the above code currently, I'm just removing the entire label and creating new one. Is it possible to get existed "my_label" in mouseMoveEvent() and update setGeometry() and setPixmap() things only instead of removing entire label and recreating label with new values. Thanks in advance.
