Delete the widgets that are in the layout before adding new ones.

yeh i had write the code like that but its not working..

for(int i=0;i<6;i++)
{
for(int j=0;j<7;j++)
{

controlsLayout->removeWidget(cellBut[i][j]);
}
}

What do you consider "not working"? removeWidget() doesn't delete the widget so it stays on the form right where it was, only that it is not managed by a layout anymore.

Actually it remove buttons at last row..but doesnt remove buttons at first row..

Try calling "delete" on the widget instead.

hello wysota

how can i interact with each buttons that i have used in creating my custom
calender means i want to say suppose i click one button than it will give
all the information of that buttons ie in which month,which week ie
sun,mon,tue..etc is shown in textBrowser.

i have tried to done one thing..

for(int i=0;i<6;i++)
{
for(int j=0;j<7;j++)
{
cellBut[i][j]=new QPushButton;
connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(showDialog()));
}
}
void MainWindow::showDialog()
{
txtDateDisplay->setText("Hello");
}

for(int i=0;i<6;i++)
{
for(int j=0;j<7;j++)
{
cellBut[i][j]=new QPushButton;
connect(cellBut[i][j],SIGNAL(clicked()),this,SLOT(showDialog()));
}
}
void MainWindow::showDialog()
{
txtDateDisplay->setText("Hello");
}

To copy to clipboard, switch view to plain text mode 

now here on each button click i simply set a text hello in the txtDateDisplay..now if i want that on each button click i set the text that appear on button in txtDateDisplay than how should i do it..because here i cant pass arguments in SIGNAL(Clicked()) function..

Rahul
