wysota> Thnks for replying me
my question is :
i) how to create forms from QT by reading from SQLITE table

following is the code im using to show one window.
Qt Code: 
  1. #include <QApplication>
  2.  #include <QGridLayout>
  3.  #include <QPushButton>
  4.  #include <QTextBox>
  5.  #include <QProcess>
  6.  #include "Connection.h"
  7.  #include <QtCore/QVariant>
  8.  
  9.  int main(int argc, char *argv[])
  10.  {
  11.         QApplication app(argc, argv);
  12.         QWidget *win1 = new QWidget;
  13.         QGridLayout *layout = new QGridLayout;
  14.         QPushButton *ClickButton=new QPushButton("Click");
  15.         QPushButton *CancelButton=new QPushButton("Cancel");
  16.         QObject::connect(ClickButton,SIGNAL(clicked()),&app,SLOT(quit()));
  17.         if(!createConnection())
  18.                 return 1;
  20.         q.exec("SELECT * FROM ConfigTable");
  21.         q.next();
  22.         win1->setWindowTitle("Window1");
  23.         win1->setFixedHeight(q.value(2).toInt());
  24.         win1->setFixedWidth(q.value(3).toInt());
  25.         layout->addWidget(ClickButton,0,0);
  26.         layout->addWidget(CancelButton,0,2);
  27.         win1->setLayout(layout);
  28.         win1->show();
  29.         return app.exec();
  30. }
To copy to clipboard, switch view to plain text mode 

How to create more than one windows, if the ConfigTable contain 2 or more records?

Thnks
