You can click View > Toolbox on the menu bar, or the Toolbox button 
on the View toolbar to show the Toolbox panel.
This panel lists all the objects that can be inserted into a report, which are classified as JReport Components, Web Controls, and Multimedia Objects. In fact, it is a shortcut to some items on the Insert menu. The method to create an object using the Toolbox panel is to drag a button representing that object from the Toolbox panel to the desired location in the report design window.
