    Default How to change push button text by clicking on another push button

    I added 2 Push buttons in ui like this qtt.jpg

    i added a slot for button "CLICK",

    Qt Code:
    1. void MainWindow::on_pushButton_clicked()
    2. {
    3.  
    4. }
    To copy to clipboard, switch view to plain text mode 

    when i click on this button "CLICK" i want the button's "BUTTON" text to be changed to "CLICKED".
    How can i do that ?

    Call setText() on the other button object.

    Since you are using Designer you likely have two member variables accessible through the ui pointer:
    Qt Code:
    1. QPushButton *pushButton; // the "CLICK" button object
    2. QPushButton *pushButton2; // the other button object
    To copy to clipboard, switch view to plain text mode 
    then
    Qt Code:
    1. void MainWindow::on_pushButton_clicked()
    2. {
    3. ui->pushButton2->setText("CLICKED");
    4. }
    To copy to clipboard, switch view to plain text mode
