Controlling Multiple UI files in Qt framework - c++

Question

Question asked twice: see Handling multiple ui files in Qt
I am new to Qt framwork , i have been given this simple task:
In the MainWindow , i have a submit button , once its clicked another total different window should appear
i thought of doing this by doing one extra UI file called From.ui file and to switch from MainWindow to Form once submit is clicked , this is my code:
//main.cpp
#include "mainwindow.h"
#include <QtGui/QApplication>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MainWindow mainWindow;
mainWindow.setOrientation(MainWindow::ScreenOrientationAuto);
mainWindow.showExpanded();
return app.exec();
}
//MainWindow.cpp
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include "form.h"
#include <QtCore/QCoreApplication>
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent), ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow:: SubmitClicked()
{
Form* f= new Form(this);
f->show();
f->raise();
f->activateWindow();
}
//Form.cpp
#include "form.h"
#include "ui_form.h"
Form::Form(QWidget *parent) :
QWidget(parent),
ui(new Ui::Form)
{
ui->setupUi(this);
}
Form::~Form()
{
delete ui;
}
this code compiled perfectly , but its not doing as expected , once submit is clicked , nothing is done...
can you please tell me whats wrong ?

Answer 1

It seems that SubmitClicked slot is not connected to clicked event of your button
Put a cout/printf at the top of your SubmitClicked method to make sure that it is called.
