Also, pressing enter in a text box causes the callback to be executed.  cdata - an M x N x 3 array that represents an RGB image to use as the truecolor image displayed on push bottons or toggle buttons. The values must be between 0 and 1.  children - Not used.  createfcn - Not used.  deletefcn - Not used;  enable - {'on','inactive','off'} - For on (the default) the uicontrol behaves normally. For inactive, it is not operational, but looks the same as on. For off, the control is grayed out.  extent - a read only property that contains the extent of the text for the control.  fontangle - {'normal','italic','oblique'} - The angle of the fonts used for text labels (e.g., tick labels).  fontsize - scalar - The size of fonts used for text labels (tick labels).  fontunits - Not used.  fontname - string - The name of the font to use for the widget.  fontweight - {'normal','bold','light','demi'} - The weight of the font used  foregroundcolor - colorspec - the foreground color for text.  handlevisibility - Not used.  hittest - Not used.  horizontalalignment - {'left','center','right} - determines the justification of text.  interruptible - Not used.  keypressfcn - functionspec - a string or function handle that is called when a key is pressed and a uicontrol object has focus.  listboxtop - a scalar (used only by the listbox style of uicontrols) that specifies which string appears at the top of the list box.  max - a scalar that specifies the largest value allowed for the value property. The interpretation varies depending on the type of the control  check boxes - specifies what value is set to when the check box is selected.  edit box - if max-min>1 then the text box allows for multiple lines of input. Otherwise, it is a single line only.  list box - if max-min>1 then multiple item selections are allowed. Otherwise, only single item selections are allowed.  radio buttons - specifies what value is set to when the radio button is selected.  slider - the maximum value the slider can take.  toggle button - specifies what value is set to when the toggle button is selected.  min - a scalar that specifies the smallest value for the value property.

If width>height then sliders are horizontal, otherwise the slider is oriented vertically.  selected - {'on','off'} - not used.  selectionhighlight - {'on','off'} - not used.  sliderstep - a two vector [min_step max_step] that controls the amount the slider value changes when you click the mouse on the control. If you click the arrow for the slider, the value changes by min_step, while if you click the trough, the value changes by max_step. Each value must be in the range [0,1], and is a percentage of the range max-min.  string - string - the text for the control.  style - @|{'pushbutton','toggle','radiobutton','checkbox', 'edit','text','slider','frame','listbox','popupmenu'}|.  tag - string - user specified label.  tooltipstring - string the tooltip for the control.  type - string - the text is set to 'uicontrol'.  uicontextmenu - handle the handle of the uicontextmenu that shows up when you right-click over the control.  units - not used.  userdata - array - any data you want to associate with the control.  value - The meaning of this property depends on the type of the control: max when checked, and min when off.  1 corresponding to the first item in the list.  max when selected, and set to min when not selected.  max when selected, and set to min when not selected.  visible - {'on','off'} - controls whether the control is visible or not
