Creating Dynamic GridLayout
-
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++; }
