qt change window title

To change the window title in a Qt application using C++, you can follow these steps:

1. Open the source file for the main window or the window where you want to change the title. This file typically has a .cpp extension.

2. Locate the function where the window is created. This function is usually named MainWindow::MainWindow or similar.

3. Inside the function, find the line where the window is created using the QMainWindow class. It typically looks like this:

cpp QMainWindow *window = new QMainWindow;

1. After the line where the window is created, add the following line to change the window title:

cpp window->setWindowTitle("New Window Title");

Replace "New Window Title" with the desired title for your window.

1. Save the file and rebuild your project. When you run the application, the window title should be updated.

By following these steps, you can easily change the window title in a Qt application using C++.
