ihandle -- handle value (an integer number) that unequivocally references the corresponding valuator. It can be used for the idisp argument of a valuator.
"label" -- a double-quoted string containing some user-provided text, placed near the corresponding widget.
iwidth -- width of widget.
iheight -- height of widget.
ix -- horizontal position of upper left corner of the valuator, relative to the upper left corner of corresponding window (expressed in pixels).
iy -- vertical position of upper left corner of the valuator, relative to the upper left corner of corresponding window (expressed in pixels).
Note that FLvalue is not a valuator and its value is fixed. Its value cannot be modified.
FLvalue shows the current values of a valuator in a text field. It outputs ihandle that can then be used for the idisp argument of a valuator (see the FLTK Valuators section). In this way, the values of that valuator will be dynamically be shown in a text field.
Here is an example of the flvalue opcode. It uses the files flvalue.orc and flvalue.sco.
