UICOMPONENT is intended as a direct replacement of Matlab's built-in UICONTROL and JAVACOMPONENT functions. It accepts all parameters and styles that UICONTROL accepts, as well as any other displayable Java (Swing/AWT) component class. The calling convention and syntax of UICONTROL were preserved for full backwards compatibility.

UICOMPONENT uses the built-in UICONTROL whenever possible (i.e, for all the standard styles), and uses JAVACOMPONENT to create and display all the other java classes. UICOMPONENT supports the entire Swing/AWT and any user-defined classes, in several equivalent case-insensitive formats. For example, 'Spinner', 'spiNNer', 'JSpinner' and 'javax.swing.jspinner' are all equivalent and recognized.
Notable new styles that are now available (unavailable in built-in UICONTROL): spinner, slider, editable comboBox, passwordField, tree, table, fileChooser, colorChooser, progressBar, applet. But there are so many more - whatever is available in Java is now seamlessly available in your Matlab GUI.

Examples (more examples in attached screenshot & in the help comment):
- uicomponent('style','jspinner','value',7); % simple spinner with initial value
- uicomponent('style','javax.swing.jslider','tag','myObj'); % simple horizontal slider
- uicomponent('style','JComboBox',{1,pi,'text'},'editable',true); % editable drop-down
The screenshot can be recreated using the createScreenshot script that is included in this submission. It is provided to illustrate the use of UICOMPONENT for various different components.

Callbacks:
Over 30 callback hooks are exposed to the user for all components (the exact list depends on the specific java component used). These callbacks include mouse movement/clicks, keyboard events, focus gain/loss, data changes etc.

Warning:
This code heavily relies on undocumented and unsupported Matlab functionality. It works on Matlab 7+, but use at your own risk!
