        gd.dispose();
        super.paintComponent(g);
    }

    public Color getWarnaBackground() {
        return this.WarnaBackground;
    }

    public void setWarnaBackground(Color bgColor) {
        this.WarnaBackground = bgColor;
    }

//Warna mouse hover Button
    public Color getMouseHover() {
        return this.MouseHover;
    }

    public void setMouseHover(Color mousehover) {
        this.MouseHover = mousehover;
    }

//Warna mouse press Button
    public Color getMousePress() {
        return this.MousePress;
    }

    public void setMousePress(Color mousepress) {
        this.MousePress = mousepress;
