Dynamically created buttons.

[Tomasz]

Hello!

I've got a problem with buttons and pointers. I need to create dynamically something like "array" of buttons on one of my application windows (each time the window opens). Now I've got some code:

QPushButton *btn[HOW_MANY_BUTTONS];
 
    for(int j=0; j<HOW_MANY_BUTTONS; j++)
    {
        btn[j] = new QPushButton;
        btn[j]->setGeometry(0,0,40,40);
 
        ui->verticalLayout->addWidget(btn[j],Qt::AlignVCenter);
    }

QPushButton *btn[HOW_MANY_BUTTONS];

    for(int j=0; j<HOW_MANY_BUTTONS; j++)
    {
        btn[j] = new QPushButton;
        btn[j]->setGeometry(0,0,40,40);

        ui->verticalLayout->addWidget(btn[j],Qt::AlignVCenter);
    }

To copy to clipboard, switch view to plain text mode 

It works just fine. But number of buttons is changing, and I don't want to create array of pointers which is bigger or smaller than number of buttons. Any suggestions how should I write function which is creating as many buttons as I need in a moment?

thanks in advance
best regards
Tomasz
