Hide Grid Widget

[shreya_agrawal]

I hide the gridWidget, but ti is still taking space. I want imageWidget to take full space when state is Qt::Checked. How can I do it?

void Home::liveViewStateChanged(int state)
{
    if(state == Qt::Checked) {
        myl.reset(new MyLabel(this)); // IRSPL0092 #490 smart pointer
        myl->setGeometry(myl->geometry().x(),myl->geometry().y(),20,20);
        myl->setSizePolicy(QSizePolicy::Expanding,QSizePolicy::Expanding);
        myl->setObjectName(QString::fromUtf8("label"));
        myl->setAlignment(Qt::AlignCenter);
        ui->verticalLayout_4->addWidget(myl.get());
        connect(this, &Home::setImageSignal, this, &Home::setImage);
        connect(this,&Home::setBlankSignal, this,&Home::setBlank);
        ui->verticalLayout_3->removeWidget(ui->gridWidget);
        ui->gridWidget->setSizePolicy(QSizePolicy::Ignored, QSizePolicy::Ignored);
        ui->gridWidget->hide();
        ui->verticalLayout_3->setStretch(0, 0);
        ui->verticalLayout_3->setStretch(1, 1);
        ui->imageWidget->show();
    } else {
        disconnect(this, &Home::setImageSignal, this, &Home::setImage);
        disconnect(this,&Home::setBlankSignal, this,&Home::setBlank);
        if (myl != nullptr) {
            myl->deleteLater();
            myl.reset(nullptr);
        }
        ui->imageWidget->hide();
        ui->verticalLayout_3->setStretch(0, 70);
        ui->verticalLayout_3->setStretch(1, 30);
        ui->verticalLayout_3->insertWidget(0, ui->gridWidget);
        ui->gridWidget->setSizePolicy(QSizePolicy::Preferred, QSizePolicy::Preferred);
        ui->gridWidget->show();
    }
}

How can I do it?

Remove gridWidget from the layout or change its size to 0
