How to Create control Array in QT4

[umulingu]

Hai

How to create control array like other programming languages.
and how to convert integer to string?..

int i=8;
 
lineEdit->setText(tr("%1").arg(i));   // its working is there any other way..

int i=8;

lineEdit->setText(tr("%1").arg(i));   // its working is there any other way..

To copy to clipboard, switch view to plain text mode

QString::number(i)

QString::number(i)

What do you mean with "control array like other programming languages"?

Thanks

Control Array means group of controls with same name.

Eg.

I want 10 lineEdit in same name [lineEdit] with index

lineEdit[0]->setText("suresh");
lineEdit[1]->setText("suresh");
lineEdit[2]->setText("suresh");
.
.
.
lineEdit[9]->setText("suresh");

lineEdit[0]->setText("suresh");
lineEdit[1]->setText("suresh");
lineEdit[2]->setText("suresh");
.
.
.
lineEdit[9]->setText("suresh");

Something like this :

QDialog dlg;
	QVBoxLayout *vl=new QVBoxLayout(&dlg);
	dlg.setLayout(vl);
	QList <QPushButton*> btnList;
	for(int i=0;i<10;i++)
	{
		QPushButton *btn = new QPushButton("Hello", &dlg);
		vl->addWidget(btn);
		btnList << btn;
	}	
	dlg.exec();

QDialog dlg;
	QVBoxLayout *vl=new QVBoxLayout(&dlg);
	dlg.setLayout(vl);
	QList <QPushButton*> btnList;
	for(int i=0;i<10;i++)
	{
		QPushButton *btn = new QPushButton("Hello", &dlg);
		vl->addWidget(btn);
		btnList << btn;
	}	
	dlg.exec();

It's better to use an iterator like the following

QList<QLineEdit*> lineEdits;
for(QList<QLineEdit*>::iterator iter = lineEdits.begin(); iter != lineEdits.end(); ++iter) {
   (*iter)->setText("Some Text");
    // In Qt i think you can also use the following
    // iter->setText("Some Text");
}

QList<QLineEdit*> lineEdits;
for(QList<QLineEdit*>::iterator iter = lineEdits.begin(); iter != lineEdits.end(); ++iter) {
   (*iter)->setText("Some Text");
    // In Qt i think you can also use the following
    // iter->setText("Some Text");
}

or an foreach loop:

foreach(QLineEdit* le, lineEdits) {
   le->setText("Some Text");
}

foreach(QLineEdit* le, lineEdits) {
   le->setText("Some Text");
}
