Newbie Trying to Learn QStackedWidget

Pages: Prev | 1 | 2 | Next
Message 1 in thread

Hi,

I am new to C++ and Qt and am trying to learn the basics of a
QStackedWidget.  All I'm trying to do at this stage is add a couple of
basic forms to the QStackedWidget and then display each form when a
menu item is chosen.

To do this I have copied and adapted the following code from books and examples:
/*********
 * Form1.h
 *********/
#include <QtGui>
#include "ui_Form1.h"

class Form1 : public QWidget,
			  public Ui::Form1
{

	Q_OBJECT

	public:
		Form1(QWidget* parent = 0);
		~Form1();

};

/***********
 * Form1.cpp
 ***********/
#include <QWidget>
#include "Form1.h"

Form1::Form1(QWidget* parent)
{
	setupUi(this);
}

Form1::~Form1()
{

}

/*********
 * Form2.h
 *********/
#include <QtGui>
#include "ui_Form2.h"

class Form2 : public QWidget,
			  public Ui::Form2
{

	Q_OBJECT

	public:
		Form2(QWidget* parent = 0);
		~Form2();

};

/***********
 * Form2.cpp
 ***********/
#include <QWidget>
#include "Form2.h"

Form2::Form2(QWidget* parent)
{
	setupUi(this);
}

Form2::~Form2()
{

}

/**************
 * mainwindow.h
 **************/
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>
#include "ui_Stacked.h"

class MainWindow : public QMainWindow,
                   public Ui::MainWindow
{
  Q_OBJECT
  public:
    MainWindow(QWidget* parent = 0);
    ~MainWindow();

  protected:
    void setupActions();
  protected slots:
    void showForm1();
    void showForm2();
};
#endif // MAINWINDOW_H

/****************
 * mainwindow.cpp
 ****************/
#include <QtGui>
#include "mainwindow.h"
#include "Form1.h"
#include "Form2.h"

// Constructor
MainWindow::MainWindow(QWidget* parent)
 : QMainWindow(parent)
{
  setupUi(this);
  setupActions();

}

// Destructor
MainWindow::~MainWindow()
{

}

void MainWindow::setupActions()
{
  connect(actionShow_Form_1, SIGNAL(triggered(bool)),
          qApp, SLOT(showForm1()));
  connect(actionShow_Form_2, SIGNAL(triggered(bool)),
          qApp, SLOT(showForm2()));

}

void MainWindow::showForm1()
{
	stackedWidget->setCurrentIndex(0);
}

void MainWindow::showForm2()
{
	stackedWidget->setCurrentIndex(1);
}

/**********
 * main.cpp
 **********/
#include <QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);

    MainWindow mainWindow;
    mainWindow.show();

    return a.exec();
}

Could someone please tell me where I add each Form to the
QStackedWidget?  I have tried various things as part of the MainWindow
constructor but get errors with whatever I try.

Many thanks,

Peter.

Message 2 in thread

Inyour MainWindow cosntructor... Create 2 forms, and the stacked
widget...

Ie
form1 = new Form1;
form2 = new Form2;

stackedWidget = new QStackedWidget( this );
stackedWidget->addWidget( form1 );
stackedWidget->addWidget( form2 );

Message 3 in thread

Hi Scott,

Thanks for your reply.

I have tried a couple of ways to do this, when I add your suggestion
and try to 'make' it again:

mainwindow.cpp: In constructor `MainWindow::MainWindow(QWidget*)':
mainwindow.cpp:16: error: `form1' undeclared (first use this function)
mainwindow.cpp:16: error: (Each undeclared identifier is reported only once for
each function it appears in.)
mainwindow.cpp:17: error: `form2' undeclared (first use this function)

mingw32-make[1]: Leaving directory `C:/Qt/4.4.0/projects/Stacked'
mingw32-make: *** [release] Error 2

if I then put:

 Form1 form1 = new Form1;
 Form2 form2 = new Form2;

 stackedWidget = new QStackedWidget( this );
 stackedWidget->addWidget( form1 );
 stackedWidget->addWidget( form2 );

I get the following errors:

You must write:
Form1* form1 = new Form1;
Form2* form2 = new Form2;

Problem is, this will result in a memory leak. You should clean up after 
yourself. Since (AFAIK) the stacked widget does not take ownership of the 
widgets you add, you should set the ownership yourself, so they get deleted 
when your window is deleted.

Form1* form1 = new Form1(this);
Form2* form2 = new Form2(this);

I meant he didn't declare form1 and form2 as pointers, what's incorrect  
when they are created using "new" operator. :)

I know :-)
It was not meant as a correction, but as a supplement to your suggestion :-)

Message 8 in thread

thanks everyone for the input.  Those little stars sure are useful aren't they?

I tried running the program but none of the menus work.  It looks as
though the submenu is stuck behind the main menu on the main menu bar.
 My menu is:
Form 1
- Show Form 1

Form 2
- Show Form 2

But it appears as:
Form 1  Form 2  with "Show Form 1" in the background.  I have attached
a screenshot but not sure if the list accepts them.

I tried running the program on windows but there are no errors showing
in the cmd box.  I am now in Linux (Ubuntu) and when I run the program
and try to access the menus I get:

$ ./Stacked
Object::connect: No such slot QApplication::showForm1()
Object::connect:  (sender name:   'actionShow_Form_1')
Object::connect:  (receiver name: 'Stacked')
Object::connect: No such slot QApplication::showForm2()
Object::connect:  (sender name:   'actionShow_Form_2')
Object::connect:  (receiver name: 'Stacked')

but when I look in my *.ui files the action's are there:
$ grep actionShow_Form_1 *
mainwindow.cpp:  connect(actionShow_Form_1, SIGNAL(triggered(bool)),
Binary file mainwindow.o matches
Binary file moc_mainwindow.o matches
Binary file Stacked matches
Stacked.ui:    <addaction name="actionShow_Form_1" />
Stacked.ui:  <action name="actionShow_Form_1" >
ui_Stacked.h:    QAction *actionShow_Form_1;
ui_Stacked.h:    actionShow_Form_1 = new QAction(MainWindow);
ui_Stacked.h:
actionShow_Form_1->setObjectName(QString::fromUtf8("actionShow_Form_1"));
ui_Stacked.h:    menuForm1->addAction(actionShow_Form_1);
ui_Stacked.h:
actionShow_Form_1->setText(QApplication::translate("MainWindow", "Show
Form 1", 0, QApplication::UnicodeUTF8));


Can someone please tell me what may be causing this?

Many thanks,

Peter.

Actually what appears in the screenshot, behind the main menus: "This
is Form 1" is a label I have placed in the center of Form1, I have
attached the *.ui files here in case they help.

Message 10 in thread

Well I've fixed the problem with the menu.  I already have a
QStackedWidget as the widget between my menu and my status bar.  So
rather than creating another one i removed the following line from
mainwindow.cpp:

//stackedWidget = new QStackedWidget( this );

but I'm still getting the no such slot errors.

Does anyone know why this is?

Thanks again for all the help.

Peter.

look at your connect statements and replace "qApp" with "this" ;-)

Thank you very much Andre!

Almost there.  The only thing left is that when I click on each sub
menu, nothing appears in the MainWindow.  I placed a single label as
the only widget for each form saying "This is Form 1" and "This is
Form 2" respectively.  But the MainWindow remains blank only
displaying the menu bar and the status bar with nothing in between.

Can someone please tell me why this is?

Again thank you for all the help.

Sorry for spamming the list with my questions.

That's not correct! stackedWidget->addWidget() does indeed transfer ownership (i.e. sets the parent).

This should be clarified in the docs though - there is no word about this in there, when other classes specify this behaviour.

Guess i'll report this to qt-bugs.

Cheers,
Peter

Thank you for the correction. I do think this is documentation bug as you 
said, because something like that should be documented in the stackedWidget 
docs.

Hi,

i think there is a little stars missing in the code :

 Form1 *form1 = new Form1;
 Form2 *form2 = new Form2;

Then the rest should be good.

Cheers
