The JadeRichText control automatically supports scrolling when the text to be displayed exceeds the dimensions of the control. The actual display of scroll bars is dependent on the value of the scrollBars property.
No horizontal scrolling takes place by default, as the text is wrapped horizontally within the bounds of the control. Use the lineWidth property to specify the width of a line. If the line width exceeds the client area width of the control, horizontal scrolling is enabled and horizontal scroll bars are displayed, if required.
