! ======================================================================
! The xcb widget hierarchy consists of a number of custom buffer
! widgets contained within a single Athena form widget.
! The widget names and classes are as follows:
!
! buffer widgets name = "buffer<NN>" class = "Buffer"
! form widget name = "container" class = "Form"
! Buffer widgets are numbered from 0... onwards, and are named accordingly.
! As well as the standard core resources, each buffer widget supports
! resources for "foreground" and "fontSet".
! Application wide resources are as follows:
!
! "bufferCount" (default value 8)
! This is the number of buffer widgets to create.
! Any number of widgets (greater than zero) can be created.
!
! "layout" (default value "h")
! Only the first character of the resource value is significant.
! This is the geometry arrangement to apply in the container widget.
! The layout can be "h" (horizontal), "v" (vertical), or some
! other value to disable the inbuilt geometry code and specify
! the layout via your X resources.
Xcb.bufferCount: 8
Xcb.layout: horizontal
Xcb*fontSet: fixed
Xcb*borderWidth: 1
Xcb*Buffer.width: 60
Xcb*Buffer.height: 60
Xcb*container.defaultDistance: 0
! Below is an example of a layout scheme which arranges
! 10 cut buffer widgets in two rows of 5 windows.
! Refer to the "Athena Widget Set" manual for full details.
