problem in window to enter information

**robelle** · 2nd October 2012, 08:43

Hi,
i want when clic in button i see window where i enter name and number

i make like that

Qt Code:

Switch view

Add = new QToolButton(page_13);
Add->setObjectName(QString::fromUtf8("Add"));
Add->setGeometry(QRect(150, 9, 51, 31));
Add->setText("Aadd");
connect(Add, SIGNAL(clicked()),mQOgreWidget,SLOT(AddInfo()));

Add = new QToolButton(page_13);
Add->setObjectName(QString::fromUtf8("Add"));
Add->setGeometry(QRect(150, 9, 51, 31));
Add->setText("Aadd");
connect(Add, SIGNAL(clicked()),mQOgreWidget,SLOT(AddInfo()));

To copy to clipboard, switch view to plain text mode

in AddInfo() i make like that

Qt Code:

Switch view

QString Nom_Segment = QInputDialog::getText(this, "Name", "Name");
int entier = QInputDialog::getInteger(this, "Number", "Number");

QString Nom_Segment = QInputDialog::getText(this, "Name", "Name");
int entier = QInputDialog::getInteger(this, "Number", "Number");

To copy to clipboard, switch view to plain text mode

But like that i see one window where i enter just the name when i close it i see another one where i enter the number

BUT it's not what i want i want to enter the a both in one window

A good place to start would be to do any tutorial on Qt that is based on QDialog.

**robelle** · 2nd October 2012, 10:06

ok
as i see here
http://doc.qt.digia.com/4.6/dialogs-extension.html
the qdialog in my case will be a widget

Added after 57 minutes:

I have just another question
i make like that

Qt Code:

Switch view

connect(Add, SIGNAL(clicked()),mQOgreWidget,SLOT(showdialogue()));

connect(Add, SIGNAL(clicked()),mQOgreWidget,SLOT(showdialogue()));

To copy to clipboard, switch view to plain text mode

and

Qt Code:

Switch view

void MainWindow::showdialogue()  
    {  
     QWidget fenetre;  
 
        QLineEdit *nom = new QLineEdit;  
        QLineEdit *nombre = new nombre;  
 
        QFormLayout *layout = new QFormLayout;  
        layout->addRow("nom", nom);  
         layout->addRow("nombre", nombre);  
 
        fenetre.setLayout(layout);  
 
        fenetre.show();

void MainWindow::showdialogue()  
    {  
     QWidget fenetre;  
      
        QLineEdit *nom = new QLineEdit;  
        QLineEdit *nombre = new nombre;  
      
        QFormLayout *layout = new QFormLayout;  
        layout->addRow("nom", nom);  
         layout->addRow("nombre", nombre);  
      
        fenetre.setLayout(layout);  
      
        fenetre.show();

To copy to clipboard, switch view to plain text mode

my question is : the widget fenÃªtre i must define it in another class ?

That's not a good tutorial. Start with the Addressbook tutorial.

**robelle** · 2nd October 2012, 11:00

ok i make like that
i create new class "formulaire_segment"
"add_segment.h"

Qt Code:

Switch view

#ifndef FORMULAIRE_SEGMENT_H
#define FORMULAIRE_SEGMENT_H 
 
 
#include <QWidget>
#include <QLineEdit>
#include <QtGui>
 
class formulaire_segment : public QWidget
{
    Q_OBJECT
 
public :
    formulaire_segment();
 
private:
    QLineEdit *nom;
    QLineEdit *nombre;
    QLabel *nom_segment;
    QLabel *nombre_points;
    QPushButton *Bouton;
};
 
#endif

#ifndef FORMULAIRE_SEGMENT_H
#define FORMULAIRE_SEGMENT_H 


#include <QWidget>
#include <QLineEdit>
#include <QtGui>

class formulaire_segment : public QWidget
{
    Q_OBJECT

public :
    formulaire_segment();

private:
    QLineEdit *nom;
    QLineEdit *nombre;
    QLabel *nom_segment;
    QLabel *nombre_points;
    QPushButton *Bouton;
};

#endif

	//creation des labels 
	nom_segment=new QLabel("nom_segment");
	nombre_points=new QLabel("nombre_points");
 
	//creation des edit 
	nom= new QLineEdit("", this);
	nom->setGeometry(310, 15, 30, 30);
 
	nombre= new QLineEdit("", this);
	nombre->setGeometry(260, 55, 30, 30);
}

#include"formulaire_segment.h"

	nombre= new QLineEdit("", this);
	nombre->setGeometry(260, 55, 30, 30);
}

BUT when i clic on the button nothing happen i do not see the 2 window

**boudie** · 2nd October 2012, 11:26

Change this:

Qt Code:

Switch view

connect(AddSegm, SIGNAL(clicked()),mQOgreWidget,SLOT(showdialogue()));

connect(AddSegm, SIGNAL(clicked()),mQOgreWidget,SLOT(showdialogue()));

To copy to clipboard, switch view to plain text mode

to:

Qt Code:

Switch view

connect(AddSegm, SIGNAL(clicked()),this,SLOT(showdialogue()));

connect(AddSegm, SIGNAL(clicked()),this,SLOT(showdialogue()));

To copy to clipboard, switch view to plain text mode

**robelle** · 2nd October 2012, 11:52

thanks , it work now
but i do not see the labels

**wysota** · 2nd October 2012, 12:04

Because you didn't use layouts.

**robelle** · 2nd October 2012, 12:25

i added layout but nothing is happend

Qt Code:

Switch view

formulaire_segment::formulaire_segment():QWidget()
{
	setFixedSize(440, 140);
	//creation des labels 
	nom_segment=new QLabel("nom_segment");
	nom_segment->setFont(QFont("Arial", 20));
	nom_segment->setGeometry(20, 20, 440, 20);
 
	nombre_points=new QLabel("nombre_points");
	nombre_points->setFont(QFont("Arial", 12));
    nombre_points->setGeometry(20, 60, 440, 20);
 
	//creation des edit 
	nom= new QLineEdit("", this);
	nom->setGeometry(310, 15, 30, 30);
 
	nombre= new QLineEdit("", this);
	nombre->setGeometry(260, 55, 30, 30);
 
	  QGridLayout *mainLayout = new QGridLayout;
     mainLayout->addWidget(nom_segment, 0, 0);
     mainLayout->addWidget(nombre_point, 0, 1);
     mainLayout->addWidget(nom, 1, 0);
     mainLayout->addWidget(nombre, 1, 1);

formulaire_segment::formulaire_segment():QWidget()
{
	setFixedSize(440, 140);
	//creation des labels 
	nom_segment=new QLabel("nom_segment");
	nom_segment->setFont(QFont("Arial", 20));
	nom_segment->setGeometry(20, 20, 440, 20);

	nombre_points=new QLabel("nombre_points");
	nombre_points->setFont(QFont("Arial", 12));
    nombre_points->setGeometry(20, 60, 440, 20);
	
	//creation des edit 
	nom= new QLineEdit("", this);
	nom->setGeometry(310, 15, 30, 30);

	nombre= new QLineEdit("", this);
	nombre->setGeometry(260, 55, 30, 30);

	  QGridLayout *mainLayout = new QGridLayout;
     mainLayout->addWidget(nom_segment, 0, 0);

**wysota** · 2nd October 2012, 12:26

Please follow the tutorial I directed you to instead of blindly trying different things. Currently your layout configuration is incorrect.

**robelle** · 2nd October 2012, 13:06

yes i forget

Qt Code:

Switch view

setLayout(mainLayout);
     setWindowTitle(("formulaire"));

setLayout(mainLayout);
     setWindowTitle(("formulaire"));

**robelle** · 2nd October 2012, 17:37

it's me again
i have now problem with signal/slot

i add this in the file formulaire_segment.h

Qt Code:

Switch view

struct segm
	{
		QString  name;
		int     number;
	}S;
 
	std::vector<segm> segment;
 
 
	public slots :
		void saveinfo();
		 signals: 
		void formulaire_remplie(std::vector<segm> segme);

struct segm
	{
		QString  name;
		int     number;
	}S;

	std::vector<segm> segment;

	
	public slots :
		void saveinfo();
		 signals: 
		void formulaire_remplie(std::vector<segm> segme);

To copy to clipboard, switch view to plain text mode

and in the formulaire_segment.cpp

Qt Code:

Switch view

formulaire_segment::formulaire_segment():QWidget()
{
	setFixedSize(440, 140);
	//creation des labels 
	nom_segment=new QLabel("nom_segment");
	nom_segment->setFont(QFont("Arial", 12));
	nom_segment->setGeometry(20, 20, 440, 12);
 
	nombre_points=new QLabel("nombre_points");
	nombre_points->setFont(QFont("Arial", 12));
    nombre_points->setGeometry(20, 60, 440, 20);
 
	//creation des edit 
	nom= new QLineEdit("", this);
	nom->setGeometry(310, 15, 30, 30);
 
	nombre= new QDoubleSpinBox( this);
	nombre->setGeometry(260, 55, 30, 30);
	nombre->setRange(0, 4);
	//
	Bouton = new QToolButton(this);
	Bouton->setObjectName("Ajouter");
    Bouton->setGeometry(QRect(10, 10, 51, 31));
    Bouton->setText("Ajouter");
 
 
	  QGridLayout *mainLayout = new QGridLayout;
     mainLayout->addWidget(nom_segment, 0, 0);
     mainLayout->addWidget(/*nombre_points*/nom, 0,1);
     mainLayout->addWidget(/*nom*/nombre_points, 1, 0);
     mainLayout->addWidget(nombre, 1,1);
	  mainLayout->addWidget(Bouton, 2, 2);
	 setLayout(mainLayout);
     setWindowTitle(tr("formulaire"));
 
	  connect(Bouton, SIGNAL(clicked()), this, SLOT( saveinfo()));
 
 
}
 
void formulaire_segment:: saveinfo()
{
		segm segmente ;
 
		segmente.name=nom->text();
		segmente.number=nombre->value();
		segment.push_back(segmente);
		this->hide();
		emit formulaire_remplie(segment);
 
}

formulaire_segment::formulaire_segment():QWidget()
{
	setFixedSize(440, 140);
	//creation des labels 
	nom_segment=new QLabel("nom_segment");
	nom_segment->setFont(QFont("Arial", 12));
	nom_segment->setGeometry(20, 20, 440, 12);

	nombre_points=new QLabel("nombre_points");
	nombre_points->setFont(QFont("Arial", 12));
    nombre_points->setGeometry(20, 60, 440, 20);

	//
	Bouton = new QToolButton(this);
	Bouton->setObjectName("Ajouter");
    Bouton->setGeometry(QRect(10, 10, 51, 31));
    Bouton->setText("Ajouter");


	  QGridLayout *mainLayout = new QGridLayout;
     mainLayout->addWidget(nom_segment, 0, 0);
     mainLayout->addWidget(/*nombre_points*/nom, 0,1);
     mainLayout->addWidget(/*nom*/nombre_points, 1, 0);
     mainLayout->addWidget(nombre, 1,1);
	  mainLayout->addWidget(Bouton, 2, 2);
	 setLayout(mainLayout);
     setWindowTitle(tr("formulaire"));

	  connect(Bouton, SIGNAL(clicked()), this, SLOT( saveinfo()));
	  

}

void formulaire_segment:: saveinfo()
{
		segm segmente ;

		segmente.name=nom->text();
		segmente.number=nombre->value();
		segment.push_back(segmente);
		this->hide();
		emit formulaire_remplie(segment);
	  
}

To copy to clipboard, switch view to plain text mode

in the mainwindow.h i added

Qt Code:

Switch view

struct segm
	{
		QString  name;
		int     number;
	}S; 
public slots:
		 void showdialogue();
	 void  formulaire_remplie(std::vector<segm> segme);

struct segm
	{
		QString  name;
		int     number;
	}S; 
public slots:
		 void showdialogue();
	 void  formulaire_remplie(std::vector<segm> segme);

To copy to clipboard, switch view to plain text mode

in the .cpp

Qt Code:

Switch view

connect(AddSegm, SIGNAL(clicked()),this,SLOT(showdialogue()));
/////////////////////
void MainWindow::showdialogue()
{
 
	formulaire_segment *formulaire=new formulaire_segment();
 
 
   formulaire->show();
 
 
 
 
}
void MainWindow::formulaire_remplie(std::vector<segm> segme)
{
	printf ("je suis dans formulaire");
 
}

connect(AddSegm, SIGNAL(clicked()),this,SLOT(showdialogue()));
/////////////////////
void MainWindow::showdialogue()
{

	formulaire_segment *formulaire=new formulaire_segment();


   formulaire->show();

  

    
}
void MainWindow::formulaire_remplie(std::vector<segm> segme)
{
	printf ("je suis dans formulaire");
	
}

To copy to clipboard, switch view to plain text mode

BUT when i run the program it does not enter to "formulaire_remplie"

EDIT

i adde this line in showdialogue()

Qt Code:

Switch view

connect(formulaire,SIGNAL (formulaire_remplie(std::vector<segm> segme)),this,SLOT(formulaire_remplie(std::vector<segm> segme)));

connect(formulaire,SIGNAL (formulaire_remplie(std::vector<segm> segme)),this,SLOT(formulaire_remplie(std::vector<segm> segme)));

To copy to clipboard, switch view to plain text mode

BUT i still when i run the program he does'nt enter to the function "formulaire_remplie"

Added after 52 minutes:

it work now i maked mistake in the connect

**wysota** · 2nd October 2012, 17:37

I really suggest you do a couple of simple tutorials before doing anything serious.

You will solve your problem on your own if you can answer the following question: What are the (three) requirements that needs to be satisfied in order to use signals and slots within a class?

**robelle** · 2nd October 2012, 17:38

thanks it work now

**robelle** · 3rd October 2012, 08:22

she is me again

to save the information (name,number) i amke like that

Qt Code:

Switch view

void formulaire_segment:: saveinfo()
{
		segm segmente ;
 
		segmente.name=nom->text();
		segmente.number=nombre->value();
		segment.push_back(segmente);
		this->hide();
		emit formulaire_remplie(segment);
		segment.clear();
 
}

void formulaire_segment:: saveinfo()
{
		segm segmente ;

		segmente.name=nom->text();
		segmente.number=nombre->value();
		segment.push_back(segmente);
		this->hide();
		emit formulaire_remplie(segment);
		segment.clear();
	  
}

To copy to clipboard, switch view to plain text mode

i make segment.clear to return to the zero
but when i excute the Qdialogue for the seconde time i do not find it empty

How does "segment" influence what is shown on the GUI? Do you change the values displayed in the UI based on the segment variable anywhere? I understand you may be a beginner programmer but before doing something you should first think how this something should be done, how it is done and how the two relate to each other.

**robelle** · 3rd October 2012, 10:18

yes,
i found that the problem not with my signal
BUT
I forget to clear another vector in the slot

there is no problem now
thanks
