Basic User Interface

Every mathlet shares the same basic user interface with the following common features.


The title is shown at top of the mathlet, i.e. above the canvases and the control panel. It can be set with:


This method is defined in the BaseApplet class.

Reset Button

A generic reset button can be used to re-initialize a scene. The button itself can be added by simply calling


inside an extended BaseApplet class. By pressing the button, the method
public void reset() {

will be called in the mathlet. To react on this event you will have to implement this method in the applet-class.

Dynamic Reset Button


Screenshot Button

A generic screenshot button can be used to create screenshots and videos by capturing graphical scenes or the complete mathlet.
The button will be visible when calling


inside an extended BaseApplet class.

Using Tabs

It is possible to open a new tab in the control-panel-, canvas- and center-pane. This is done by calling
add(String, Component)

on the following getters:
  • getCanvasTabbedPane()
  • getCenterTabbedPane()
  • getControlTabbedPane()
    These methods return a customized instance of a JTabbedPane (an instance of TabbedPanel more precisly) which will show the real tab (with the tab’s title) only when more than one tab has been added.

Note: all of the BaseApplet’s tabbed panes have allready a tab (containg the canvases, etc.). But the tab’s titles are not visible because they are the only tabs! The add method of these tabbed panes request a String for the tab’s title and an instance of Component which can be e.g. a new ControlPanel, Canvas or JPanel (they all extend the class Component).

The title of the first (default) tab can be set through the TabbedPanel proper method

setTitleAt(int, String)

The instance of this underlying SWING-class can be accessed through

in the class TabbedPanel.
