The rounded rectangle tool allows you to draw a rectangle with rounded corners. Simply click and hold down the mouse, drag until you get the size rectangle you want, then release the mouse button.

The stroke width option allows you to specify how thick of a border you want for the rounded rectangle, while the current Stroke Color will be used for the color of the rounded rectangle's border.

You can also adjust the rounded corner radius by adjusting its value in the panel.

Elements drawn with the Rounded Rectangle tool can be filled with either a solid color, gradient or a pattern fill. You can also apply a drop shadow to rectangle elements, as well as bevel/emboss them, or add a glow to it.
