problem in window to enter information

[robelle]

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

i make like that


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()));

in AddInfo() i make like that


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

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

Implement a dialog that will contain both fields.

Implement a dialog that will contain both fields.
how i do that ?

did you mean that i define new widget with 2 QLineEdit,layout ?

[wysota]

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

[robelle]

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

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


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();

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

[wysota]

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

[robelle]

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




#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

add_segment.cpp




#include"formulaire_segment.h"

formulaire_segment::formulaire_segment():QWidget()
{
setFixedSize(440, 140);
//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);
}


in the mainwindows


class formulaire_segment;
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow();
public slots:
void showdialogue();


and


AddSegm = new QToolButton(page_13);
AddSegm->setObjectName(QString::fromUtf8("AddSegm"));
AddSegm->setGeometry(QRect(150, 9, 51, 31));
AddSegm->setText("Ajouter Segment");
connect(AddSegm, SIGNAL(clicked()),mQOgreWidget,SLOT(showdialogue() ));

//////////////////////////////*showdialogue slot///////////////////////////////////
void MainWindow::showdialogue()
{

formulaire_segment *formulaire=new formulaire_segment();

formulaire->show();


}



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

[boudie]

Change this:


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

to:


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

[wysota]

ok i make like that
Please follow the tutorial. In particular, use layouts.

[robelle]

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

[wysota]

Because you didn't use layouts.

[robelle]

i added layout but nothing is happend


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);

[wysota]

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

[robelle]

yes i forget :p

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

[robelle]

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

i add this in the file formulaire_segment.h


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

std::vector<segm> segment;


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

and in the formulaire_segment.cpp


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);

}

in the mainwindow.h i added


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

in the .cpp


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");

}

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

EDIT

i adde this line in showdialogue()

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

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]

thanks it work now

[robelle]

she is me again :o

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


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();

}

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]

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
