Are you sure you're new to Qt? :)
OK, first of all please always put in copy qt-interest (others may be interested).
Then, you don't have to write everything yourself; Use designer instead
to create the dialog for you and the uic utility will generate the code.
You'll gain a lot of time this way. You'll still have to create the main.cpp
You then need to subclass the dialog to re-implement the accept()
virtual slot.

I have written some code. I have not connected the signals and slots.
Just displaying.
Please check out if any error and get back.
login.h
-------
#ifndef LINEDIT_H
#define LINEDIT_H
#include <qgroupbox.h>
class QLineEdit;
class LineEdit : public QGroupBox
{
Q_OBJECT
public:
LineEdit( QWidget *parent = 0, const char *name = 0 );
protected:
QLineEdit *lined1, *lined2;
protected slots:
void slotEchoChanged();
void slotDisplayText();
}
#endif
login.cpp
---------
#include "login.h"
#include <
qlineedit.h>
#include <qcombobox.h>
#include <qframe.h>
#include <qvalidator.h>
#include <qlabel.h>
#include <qlayout.h>
#include <qhbox.h>
LineEdit::LineEdit( QWidget *parent, const char *name )
{
setMargin( 10 );
QHBoxLayout *box = new QHBoxLayout( layout() );
QHBoxLayout *row1 = new QHBoxLayout( box );
row1->setMargin( 5 );
QLabel* label = new QLabel( "UserName: ", this);
row1->addWidget( label );
lined1 = new QLineEdit( this );
box->addWidget( lined1 );
QHBoxLayout *row2 = new QHBoxLayout( box );
QLabel * label2 = new QLabel( "Password ", this );
row2->addWidget( label2 );
lined2 = new QLineEdit ( this );
box->addWidget( lined2);
}
void LineEdit::slotEchoChanged()
{
lined2->setEchoMode( QLineEdit::Password );
lined2->setFocus();
}
void LineEdit::slotDisplayText()
{
lined1->setEchomode( QLineEdit::displayText ())
-----------------------------------------
//can i use like above to display text?//
---------------------------------------
main.cpp
--------
#include "login.h"
#include <qapplication.h>
int main( int argc, char **argv )
{
QApplication a( argc, argv );
LineEdit line;
line.setCaption( "Login example" );
a.setMainWidget( &line );
line.show();
return a.exec();
