Question

Is there anything obvious wrong with this line of code? I want rectangle to stay centered regardless the size of the window. But this don´t work for some reason, the rectangle stays the same place.

    public void run() {
    setSize(800, 800);
    createEntireFigure();


}
private void createEntireFigure(){
    int centerOfWindowWidth = getWidth() / 2;
    int centerOfWindowHeight = getHeight() / 2;

    GRectWithGLabel ("A String",centerOfWindowWidth, centerOfWindowHeight); 
}

Your rectangle size code is only called on rectangle creation, and so it makes sense that the rectangle’s position will not change if the GUI is re-sized. You need to somehow listen for size changes in your GUI and call code to re-position the rectangle then for this to work. What graphics library are you using?
