在Qt框架中控制多个UI文件

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.
