Creating Dynamic GridLayout

[fnoyanisi]

Hi

For the code below, I am trying to arrange unknown number of buttons (below it is 34 to try the algorithm) in a grid layout. There will be 4 columns.

But when I run the code all the buttons are located at the same point. Isn't it supposed to be arranged in grid?

Thanks in advance...
[code]int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWidget *window = new QWidget;
QGridLayout *grid = new QGridLayout;

int r_count = (int)34/4;

for (uint r=0; r < r_count;r++){
for (uint c=0; c<4; c++)
grid->addWidget(new QPushButton("label"),r,c,0,0);
}

window->setLayout(grid);
window->show();
return app.exec();
}[/code]

I have done this code this way. Hope it helps:

@
int row=0;
int numberOfButtons=0;

while (numberOfButtons<=34)
{
    for (int f2=0; f2<4; f2++)
    {
        numberOfButtons++;

        if (numberOfButtons>34)
            break;

        QPushButton *button=new QPushButton();
        button->setText(QString::number(numberOfButtons));
        glayout->addWidget(button, row, f2);
    }
    row++;
}
