OBJECT TYPES
     xtpanel supports the following objects:


     message   Displays a single line of text. Read only.


     text      Displays multiple lines of text  in  a  scrollable
               area. Can be read/write or read only.


     field     Same as text, but for only a single line of  text.
               Always read-write.


     dialog    Like field, with a label and  an  OK  button  that
               performs some action.


     button    A single button.


     toggle    A button that can be toggled between two states.


     slider    Allows the user to choose a value from a range  of
               integer or floating point values.


     scrollbar Similar to a slider, but simpler in appearance.


     choice    A group of buttons,  only  one  of  which  may  be
               selected at a time.


     menubutton
               A button with a menu attached.


     list      A list of character strings, only one of which may
               be selected at a time.


     var       A variable that has no screen  representation  but
               stores  a  value.  A variable's actions, if it has
               any, are executed whenever the value stored in the
               variable is modified.


     timer     An object that has no  screen  representation  but
               executes  its  action[s] at set intervals, without
               user interaction.


     startup   An object that has no  screen  representation  but
               executes its action[s] at startup time.


     graph     An object containing a number of scrollbars,  each
               of  which  controls  the value for one sample of a
               list of numbers.


     grid      An object containing a two-dimensional  matrix  of
               buttons.  Pressing one of the buttons executes the
               grid's action[s], optionally  making  use  of  the
               coordinates of the selected button.


     togglegrid
               Like grid, except the buttons are replaced by tog-
               gles.   A  bitmap of the states of all the toggles
               can be generated.


     In addition there  are  several  objects  that  group  other
     objects  together  in  boxes.  Grouping  objects in this way
     allows greater control of the panel layout. See the  section
     below on BOXES AND FORMS.
