Dynamically created buttons.

[BalaQT]

hi ,
u can use QHash too.
i will use like this ,

QHash<int,QPushButton*> btn;
 
int HOW_MANY_BUTTONS=200; //u can change this value dynamically as u wish;
for(int j=0; j<HOW_MANY_BUTTONS; j++)
{
        QPushButton *b=new QPushButton;
        btn[j]=b;
        b->setGeometry(0,0,40,40);
        ui->verticalLayout->addWidget(b,Qt::AlignVCenter);        
}

QHash<int,QPushButton*> btn;

int HOW_MANY_BUTTONS=200; //u can change this value dynamically as u wish;
for(int j=0; j<HOW_MANY_BUTTONS; j++)
{
        QPushButton *b=new QPushButton;
        btn[j]=b;
        b->setGeometry(0,0,40,40);
        ui->verticalLayout->addWidget(b,Qt::AlignVCenter);        
}

To copy to clipboard, switch view to plain text mode 

hope it helps
