problem with DoubleSpinBox

Hi,
i want when i finished entred position (numbers) in 3 doublespinbox
it show to me an object
for that

i make like that, i define class

Code:

---

Coordinate3dWidget::Coordinate3dWidget(QWidget *parent):
    QWidget(parent)
{
 
            pos_cam = new QGroupBox(this);
            pos_cam->setObjectName(QString::fromUtf8("pos_cam"));
            pos_cam->setGeometry(QRect(10, 50, 191, 71));
            pos_cam->setTitle("Position");
 
          sbx_cam = new QDoubleSpinBox(pos_cam);
            sbx_cam->setObjectName(QString::fromUtf8("sbx_cam"));
            sbx_cam->setGeometry(QRect(10, 40, 51, 22));
			sbx_cam->setRange(-5000, 5000);
          lx_cam = new QLabel(pos_cam);
            lx_cam->setObjectName(QString::fromUtf8("lx_cam"));
            lx_cam->setGeometry(QRect(10, 20, 46, 13));
           lx_cam->setText(QApplication::translate("MainWindow", "X :", 0, QApplication::UnicodeUTF8));
 
            sby_cam = new QDoubleSpinBox(pos_cam);
            sby_cam->setObjectName(QString::fromUtf8("sby_cam"));
            sby_cam->setGeometry(QRect(70, 40, 51, 22));
			sby_cam->setRange(-5000, 5000);
          ly_cam = new QLabel(pos_cam);
            ly_cam->setObjectName(QString::fromUtf8("ly_cam"));
            ly_cam->setGeometry(QRect(70, 20, 46, 13));
            ly_cam->setText(QApplication::translate("MainWindow", "Y :", 0, QApplication::UnicodeUTF8));
			sbz_cam = new QDoubleSpinBox(pos_cam);
            sbz_cam->setObjectName(QString::fromUtf8("sbz_cam"));
            sbz_cam->setGeometry(QRect(130, 40, 51, 22));
			sbz_cam->setRange(-5000, 5000);
          lz_cam = new QLabel(pos_cam);
            lz_cam->setObjectName(QString::fromUtf8("lz_cam"));
            lz_cam->setGeometry(QRect(130, 20, 46, 13));
          lz_cam->setText(QApplication::translate("MainWindow", "Z :", 0, QApplication::UnicodeUTF8));
 
		    connect(sbx_cam, SIGNAL(editingFinished()), this, SLOT(onCoordinateChanged()));
	         connect(sby_cam, SIGNAL(editingFinished()), this, SLOT(onCoordinateChanged()));
	         connect(sbz_cam, SIGNAL(editingFinished()), this, SLOT(onCoordinateChanged()));
}

---

but it dos not work , it add to me 3 object (when i enter value in sbx_cam it add to me an object , when i enter value in sby_cam it add to me another !!!!!!!!!!!)
i want when i the editingFinished() of the 3 DoubleSpinBox i add the object not when i finished one

Do yourself a favour and read about using layouts.

layout!! why layout ?

Hi
i do not use layout her
i just use groupbox

Yes, I can see that.

No, you don't. And even if you did, you'd still need layouts.

As a test, use this main() with your Coordinate3dWidget class:

Code:

---

int main(int argc, char **argv) {
  QApplication app(argc, argv);
  Coordinate3dWidget w;
  QFont f;
  f.setPointSize(72);
  w.setFont(f);
  w.show();
  Coordinate3dWidget w2;
  f.setPointSize(4);
  w2.setFont(f);
  w2.show();
  return app.exec();
}

How does it look? I hope this answers rimie23's question as well. Conclusions are yours to draw.

i don't undertand what you want by this exemple

maybe you do not understand where is my problem exactelly

because i make in my mainwindow like that

Code:

---

ogreWidget = new OgreWidget(this);
    setCentralWidget(ogreWidget);
 page_14  = new Coordinate3dWidget;
onnect(page_14, SIGNAL(coordinateChanged(const Ogre::Vector3&)),
            ogreWidget, SLOT(setCameraPosition(const Ogre::Vector3&)));
    connect(ogreWidget, SIGNAL(cameraPositionChanged(const Ogre::Vector3&)),
            page_14, SLOT(setNewCoordinate(const Ogre::Vector3&)));

---

that mean i related it where i draw the object

it just do net let me finishe entring in the three spinbox

Maybe if you ran it, you'd understand.

That's true, I don't, because you are describing your problem and then showing some code totally unrelated to that (and doing that again in this post).

Since I can understand the code better than your words, I talk about problems with your code hoping (in vain, as we can see) that either you show some related code next time or fixing the problem I see will somehow influence your primary problem or at least the description of it. Currently your English is so bad I can't make up what you are talking about. I can only guess that you want a slot to be called after all three of the boxes are changed and not after each one gets a value but since you didn't show any code related to that, I'm just left with my guesses.

I am so sorry
i know that my english is bad (it's not my native language )

yes that what i want ,i want "add object" when i enter numbers in the three boxes .

I will give you all the code
in my class Coordinate3dWidget.h i have like that

Code:

---

class Coordinate3dWidget : public QWidget
{
    Q_OBJECT
public:
    Coordinate3dWidget(QWidget *parent=0);
public slots:
    void setNewCoordinate(const Ogre::Vector3 &coordinate);
signals:
    void coordinateChanged(const Ogre::Vector3 &coordinate);
private slots:
    void onCoordinateChanged();
private:
 
	QDoubleSpinBox *sbx_cam;
        QLabel *lx_cam;
        QLabel *ly_cam;
        QDoubleSpinBox *sby_cam;
        QDoubleSpinBox *sbz_cam;
        QLabel *lz_cam;
		QGroupBox *pos_cam;
 
};

in Coordinate3dWidget.cpp

Code:

---

#include <QLabel>
#include <QHBoxLayout>
#include <QToolButton>
#include <QPushButton>
 
#include "coordinate3dwidget.h"
#include"my_interface.h"
//class MainWindow;
Coordinate3dWidget::Coordinate3dWidget(QWidget *parent):
    QWidget(parent)
{
 
            pos_cam = new QGroupBox(this);
            pos_cam->setObjectName(QString::fromUtf8("pos_cam"));
            pos_cam->setGeometry(QRect(10, 50, 191, 71));
            pos_cam->setTitle("Position");
 
          sbx_cam = new QDoubleSpinBox(pos_cam);
            sbx_cam->setObjectName(QString::fromUtf8("sbx_cam"));
            sbx_cam->setGeometry(QRect(10, 40, 51, 22));
			sbx_cam->setRange(-5000, 5000);
          lx_cam = new QLabel(pos_cam);
            lx_cam->setObjectName(QString::fromUtf8("lx_cam"));
            lx_cam->setGeometry(QRect(10, 20, 46, 13));
           lx_cam->setText(QApplication::translate("MainWindow", "X :", 0, QApplication::UnicodeUTF8));
 
            sby_cam = new QDoubleSpinBox(pos_cam);
            sby_cam->setObjectName(QString::fromUtf8("sby_cam"));
            sby_cam->setGeometry(QRect(70, 40, 51, 22));
			sby_cam->setRange(-5000, 5000);
          ly_cam = new QLabel(pos_cam);
            ly_cam->setObjectName(QString::fromUtf8("ly_cam"));
            ly_cam->setGeometry(QRect(70, 20, 46, 13));
            ly_cam->setText(QApplication::translate("MainWindow", "Y :", 0, QApplication::UnicodeUTF8));
			sbz_cam = new QDoubleSpinBox(pos_cam);
            sbz_cam->setObjectName(QString::fromUtf8("sbz_cam"));
            sbz_cam->setGeometry(QRect(130, 40, 51, 22));
			sbz_cam->setRange(-5000, 5000);
          lz_cam = new QLabel(pos_cam);
            lz_cam->setObjectName(QString::fromUtf8("lz_cam"));
            lz_cam->setGeometry(QRect(130, 20, 46, 13));
          lz_cam->setText(QApplication::translate("MainWindow", "Z :", 0, QApplication::UnicodeUTF8));
 
		    connect(sbx_cam, SIGNAL(/*valueChanged*/editingFinished()), this, SLOT(onCoordinateChanged()));
	         connect(sby_cam, SIGNAL(/*valueChanged*/editingFinished()), this, SLOT(onCoordinateChanged()));
	         connect(sbz_cam, SIGNAL(/*valueChanged*/editingFinished()), this, SLOT(onCoordinateChanged()));
}
 
void Coordinate3dWidget::setNewCoordinate(const Ogre::Vector3 &coordinate)
{
    blockSignals(true);
    sbx_cam->setValue(coordinate.x);
    sby_cam->setValue(coordinate.y);
    sbz_cam->setValue(coordinate.z);
    blockSignals(false);
}
 
void Coordinate3dWidget::onCoordinateChanged()
{
    Ogre::Vector3 newCoord(sbx_cam->value(),
                           sby_cam->value(),
                           sbz_cam->value());
    emit coordinateChanged(newCoord);
}

and in my mainwindow

Code:

---

MainWindow::MainWindow()
{
    ogreWidget = new OgreWidget(this);
    setCentralWidget(ogreWidget);
    createDockWidget();
 
}
void MainWindow::createDockWidget()
{
page_14 = new Coordinate3dWidget;
page_14->setGeometry(QRect(0, 0, 211, 250));
connect(page_14, SIGNAL(coordinateChanged(const Ogre::Vector3&)),
            ogreWidget, SLOT(setCameraPosition(const Ogre::Vector3&)));
    connect(ogreWidget, SIGNAL(cameraPositionChanged(const Ogre::Vector3&)),
            page_14, SLOT(setNewCoordinate(const Ogre::Vector3&)));

---

in my class OgreWidget i defined slot

Code:

---

public slots:
        void setCameraPosition(const Ogre::Vector3 &pos);

---

Code:

---

in setCameraPosition: when i entre the numbers in the three boxes i must execute this slot to add object in the position entred 
void  QOgreWidget::setCameraPosition(const Ogre::Vector3 &pos)
{ 
 
	 CamNode=  mSceneMgr->getRootSceneNode()->createChildSceneNode();
	ent_cam = mSceneMgr->createEntity( Ogre::SceneManager:: PT_CUBE);
	Ogre::MaterialPtr material = Ogre::MaterialManager::getSingleton().create("green", "General");
	material->getTechnique( 0 )->getPass( 0 )->setAmbient(1, 1, 0);
	ent_cam->setMaterial(material);
	mSceneMgr->getRootSceneNode()->createChildSceneNode();
	CamNode->setPosition(pos);
	CamNode->attachObject(ent_cam);
 
 
}

---

Ok, now the situation is clear.

First of all please do consider using layouts in your widget and derive your widget from QGroupBox and not QWidget.

Code:

---

Coordinate3dWidget::Coordinate3dWidget(QWidget *parent):
    QGroupBox(parent)
{
    setTitle("Position");
    QGridLayout *l = new QGridLayout(this);
    lx_cam = new QLabel;
    sbx_cam = new QDoubleSpinBox;
    sbx_cam->setRange(-5000, 5000);
 
    lx_cam->setText(tr("X"));
    l->addWidget(lx_cam, 0,0);
    l->addWidget(sbx_cam, 1, 0);
 
    ly_cam = new QLabel;
    sby_cam = new QDoubleSpinBox;
    sby_cam->setRange(-5000, 5000);
    ly_cam->setText(tr("Y"));
    l->addWidget(ly_cam, 0,1);
    l->addWidget(sby_cam, 1, 1);
 
    lz_cam = new QLabel;
    sbz_cam = new QDoubleSpinBox;
    sbz_cam->setRange(-5000, 5000);
    lz_cam->setText(tr("Z"));
    l->addWidget(lx_cam, 0,2);
    l->addWidget(sbz_cam, 1, 2);
 
		    connect(sbx_cam, SIGNAL(valueChanged(double)), this, SLOT(onCoordinateChanged()));
		    connect(sby_cam, SIGNAL(valueChanged(double)), this, SLOT(onCoordinateChanged()));
		    connect(sbz_cam, SIGNAL(valueChanged(double)), this, SLOT(onCoordinateChanged()));
}

---

Isn't that clearer and doesn't it work better?

Now for your main problem... here is how your "onCoordinateChanged()" which looks like:

Code:

---

void Coordinate3dWidget::onCoordinateChanged()
{
    Ogre::Vector3 newCoord(sbx_cam->value(),
                           sby_cam->value(),
                           sbz_cam->value());
    emit coordinateChanged(newCoord);
}

---

works:
1. create a new coordinate vector
2. emit the vector

Now, it should look like this:
1. if sbx_cam, sby_cam, sbz_cam don't have a valid value, return
2. otherwise create a coordinate vector
3. and emit it

The bad thing is I have no idea how you intend to determine that a value is not valid for you. In my opinion every real value is valid so you need a separate button outside your widget to accept the value entered in those three boxes together.
I would also suggest that you provide a method for reading the current value of the coordinate vector instead of only emitting a signal with it.

i tried the function with layout
it's good

i resolved the problem by
1-adding the notion of flag for each spinbox
2-i store when i execute my program the last value entred
