displaying text

Hi,
I have a QTGLWdiget that I use as canvas for drawing. Now i want to add the following functionality:
when user clicks on some location over the camvas, a small text area appears over the canvas, containing some information about the drawing and the location where the user clicked.

I am a novoice to the QT, so I am not sure what widgets do i look into to make this popup text area possible.

thanks in advance

You don't need any widgets. Either use a tooltip or implement drawing of the tip in the paint event of the GL widget (you'll have to do some 3D math there anyway to do the proper projection).

thanks for the help, another question though :)

I have a main window where I am placing a QTextEdit as below:

Code:

---

Window::Window(QWidget *parent) : QWidget(parent) {
 
// code here
 
QTextEdit *metaDataText = new QTextEdit;
metaDataText->setText(str);
 
// code here
 
}

---

I want that the string "str" is modified in another class and updated in the Window automatically. I am not sure how to implement this?

which signal should be emitted by the class that is modifying the string?

secondly, how should I implemented the slot in the main window?

regards
