ObmW -- Custom widgets used by the Object Manager. This directory contains
standalone X toolkit widgets; these are not tied to the Object Manager in any
way. The widgets in this collection are included here if they are used in
the Object Manager but are not part of any standard toolkit.
To interface a new widget to the Object Manager, one can add the widget
source to this directory and modify ObmP.h and obmres.dat (which is generated
using obmres.c) in the OBM root directory to tell OBM about the widget and
its resources. One may optionally wish to subclass the OBM Widget class to
make any widget-specific functions available to interpreted GUI code.
Widets:
Gterm Gterm gterm-image widget (2D graphics and imaging)
Layout Layout geometry widget, uses layout description language
Arrow Arrow arrow widget, as in a scrollbar
Board Board geometry widget, organizes children by coordinate
Frame Frame draws a frame around a child widget
Group Group organize multiple children into a group
Icon Icon display a color pixmap
MultiList MultiList list widget with multiple selections
RadioGrp RadioGroup radio group, subclass of Group
RowCol RowCol geometry widget, arranges children in a table
Scrollbar Scrollbar2 alternative to Athena scrollbar widget
Slider2 Slider2D 2D slider widget (can be used as 1D slider)
Label TextBox framed box with formatted text
Button TextButton TextBox as a button with callback
Toggle TextToggle button with on,off bitmap to the left
Common XfwfCommon used internally by all FWF widgets
MenuBar MenuBar doesn't work, placeholder for now
Notes on widget callbacks (used internally by OBM, not GUIs).
