QT creates buttons that add text to the edit text box

New for QT, just playing with him to find out if he likes something that I like, and if so, then and further, and to study the program in-depth.

Damage with button concept. I created a button and a text area. I want to add a line of text to a text box when a button is clicked.

I can not find anything on google or QT wiki for this. Can someone point me in the direction so that I can at least start and play with this great tool.

In Qt, signals and slots are used to communicate between objects. This should provide you with the necessary information to get you started.

, QPushButton clicked() , , ( ):

 QPushButton * btn = new QPushButton("Button", this);
 connect(btn, SIGNAL(clicked()), this, SLOT(onBtnClicked()));

:

 private slots:
     void onBtnClicked();

:

 void MySpecialWidget::onClick() 
 {
     // Do what is to be done
 }

, ... , , :

Object::connect: No such slot MySpecialWidget::onClick() in ...


Object::connect: No such signal ....
