Resizing the dialog box dynamically

hi ,

I am new to QT.., my problem is can we resize the dialog dynamically, :confused:

i.e, using any controls, Say for eg slider, can we resize the dialog when the slider is moved

thanks in advance :)

Yes, of course. You have to connect the slider's valueChanged signal to a custom slot which will resize() the dialog.

hi
i have tried using resize(), but its not effecting on the dialog box??? :confused:

can u pl help me out.

thanks in advance,

Can you show some code you wrote for that?

here is the code :

Code:

---

int main (int argc, char *argv[]){
  QApplication app(argc, argv);
  QDialog *dialog  = new QDialog();
  QHBox *hbox = new QHBox;
  hbox->setCaption("Slider is at : ");
  hbox->setMargin(6);
  hbox->setSpacing(6);
  QSpinBox *spinbox = new QSpinBox(hbox);
  QSlider *slider = new QSlider(Qt::Horizontal, hbox);
  spinbox->setRange(0,100);
  slider->setRange(0,100);
  QObject::connect(spinbox, SIGNAL(valueChanged(int)),  slider, SLOT(setValue(int)));
  QObject::connect(slider, SIGNAL(valueChanged(int)),  spinbox, SLOT(setValue(int)));
  int x = spinbox->value();
  int y = slider->value();
  hbox->resize(x,y);
  spinbox->setValue(11);
  app.setMainWidget(hbox);
  hbox->show();
  return app.exec();
}

This only resizes the dialog to the initial state (i.e. 0 by 0 pixels). You've also interconnected the slider and the spin box. You need to subclass the dialog and create two slots - setX and setY which you then connect to the slider and spinbox.
