//form11.cpp
#include "form11.h"
#include
Form11::Form11():Form11()
{}
Form11::~Form11()
void Form11::newSlot()
{
lineEdit->setText("hellll");

public slots:
void newSlot();

#include "form11.h"
int main( int argc, char **argv)
{
QApplication a(argc,argv);
Form11 w;
w.show();
a.setMainWidget(&w);
//perform the same function as a.connect(&a, SIGNAL(lastWindowClosed()),
//&a, SLOT(quit()))
return a.exec();
}
//besides all above all you need is a form1.ui file, from1.ui.h is obtained
//automativcally. in the ui, you have a pushbutton with its signal clicked()
//connected to form1's slot newSlot(), and a lineedit.
/////////
//ui method
///////////

//the ui.h method to achieve the same effect
//you don't need form11.cpp or form11.h
//instead ui.h file with the folling code will do
void Form1::newSlot()
{
lineEdit->setText("hex");
}
//strange is that we do not have to include qlineedit.h, though
//the lineedit is used here.
//////////////////////
//the ui file is still the same, and the main.cpp is almost the same
#include"form1.h" //raher than form11.h
main()
{
From1 w;// no big deal
}
}
////////////////
//dynamic Window method (to be continued)
