(C++) How to resize a dialog?

 

There are multiple options:

1. this->resize(int any_width,int any_height)
2. this->setGeometry(int any_left, int any_right, int any_width,int any_height)
3. 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; }
