How to change window title in Qt?

Question

How to change window title in Qt? (Both for QDialog and QMainWindow .)

Answer 1

 void QWidget::setWindowTitle ( const QString & ) 

EDIT: If you use QtDesigner , the properties tab has an editable windowTitle property, which can be found in the QWidget section. The properties tab can usually be found in the lower right part of the designer window.

Answer 2

For new Qt users, this is a bit more confusing than it sounds if you use the QT Designer and .ui files.

At first I tried to use ui->setWindowTitle , but this does not exist. ui not a QDialog or QMainWindow .

The owner of ui is QDialog or QMainWindow , .ui just describes how to lay it out. In this case you should use:

 this->setWindowTitle("New Title"); 

I hope this helps someone else.

Answer 3

 system("title WhateverYouWantToNameIt");
