Hi,

What are these sections ?

[amarism]

@SGaist suppose this one is a widget. I want to highlight the widget after clicking

[SGaist]

What about QRubberBand ?

@SGaist This one not working for me

Well... With that much information, it sure is easy to help you.

You might want to consider explaining what you tried, what you got, etc.

@SGaist I used this one code for highlighting. I do not understand, why we r taking "origin". In this link http://doc.qt.io/qt-5/qrubberband.html

void mainwindow::mousePressEvent(QMouseEvent *event)
{
//origin = event->pos();
if (!this->ui->view1)
return;
this->ui->view1->setGeometry(QRect(event->pos(), QSize()));
this->ui->view1->show();
}

void mainwindow::mouseMoveEvent(QMouseEvent *event)
{
this->ui->view1->setGeometry(QRect(event->pos(), event->pos()).normalized());
}

void mainwindow::mouseReleaseEvent(QMouseEvent *event)
{
this->ui->view1->hide();
}

@SGaist
Can I create a border around it? So, it will show highlighted after clicking.

[SGaist]

In your case, you don't build the rectangle using mouse move, hence you can ignore that part. A border around what ?

@SGaist Border around the widget after mouse clicking?

After removing the mouse move code my output comes like this and when i will press after the widget 1. it will change to normal form.
