There are multiple options:

this->resize(int any_width,int any_height)
this->setGeometry(int any_left, int any_right, int any_width,int any_height)
this->setGeometry(QRect any_rect)

Resize this in a member function of the dialog.


#include "dialog.h"

#include "ui_dialog.h"



Dialog::Dialog(QWidget *parent) :

    QDialog(parent),

    ui(new Ui::Dialog)

{

  ui->setupUi(this);

  //Resize the dialog to 100x100 pixels

  this->resize(100,100);

}



Dialog::~Dialog()

{

  delete ui;

}



void Dialog::changeEvent(QEvent *e)

{

  QDialog::changeEvent(e);

  switch (e->type()) {

  case QEvent::LanguageChange:

    ui->retranslateUi(this);

    break;

  default:

    break;

  }

}



void Dialog::resizeEvent(QResizeEvent*)

{

  static int n_times = 0;

  QString s; s = s.number(n_times);

  ui->label->setText("Resized " + s + " times");

  ++n_times;

}
