How to add different widgets in same position inQGridLayout

GAURAV PANT

Hi,
I am making a Qt widget application having following wigets: button1, button2, label1, label2.
I have a QGridLayout having two rows.
In row 1 I have button1 and button2. Now if button1 is clicked then label1 is displayed in row2 and if button2 is clicked label2 is displayed in row2.

Here is my code:
@
{
QPushButton *btn1=new QPushButton("click1");
connect(btn, SIGNAL(clicked()), this, SLOT(disp1()));

QPushButton *btn2=new QPushButton("click2");
connect(btn1, SIGNAL(clicked()), this, SLOT(disp2()));

gd=new QGridLayout();
gd->addWidget(btn1,0,0);
gd->addWidget(btn2,0,1);

parent->setLayout(gd);

}

void MainWindow::disp1()
{

QLabel *lb1=new QLabel("label1");   
gd->addWidget(lb1,1,0);

}

void MainWindow::disp2()
{

   QLabel *lb2=new QLabel("label2"); 
   gd->addWidget(lb2,1,0);

}
@

Whats happening is label1 and label2 are getting overlapped but i want to display only one at a time.
I have also tried adding label1 and label2 to QFrame and then using frame1->hide() and frame2->hide() but some flickering of screen is there and a warnig is also displayed "Attempting to add QLayout to QFrame , which already has a layout"

Kindly help.

Thanks

I see two different possibilities either using "replaceWidget":http://qt-project.org/doc/qt-5/qlayout.html#replaceWidget or use "setVisible(false)":http://qt-project.org/doc/qt-5/qwidget.html#visible-prop for the widget, you do not want to see and vice versa. This can be used for QLabel and QPushButton and lot others.
