Comtrol eCos - Manual (Page 763)

The I/O Auxiliary’s User Interface
Subwindows are generally packed in one of eight frames surrounding the central text window: .main.nw , .main.n ,
.main.ne , .main.w , .main.e , .main.sw , .main.s , and .main.se . To position a row of LED’s above the text
window and towards the left, a target definition file could contain an entry such as:
synth_device led {
pack -in .main.n -side left
...
}
Similarly, to put a traffic monitor window on the right of the text window would involve something like:
...
monitor_pack -in .main.e -side bottom
...
Often it will be sufficient to specify a container frame and one of left , right , top or bottom . Full control over
the positioning requires an understanding of Tcl/Tk and in particular the packing algorithm, and an appropriate
reference work should be consulted.
Global Settings
Note: This section still to be written - it should document the interaction between X resources and ecosynth,
and how users can control settings such as the main foreground and background colours.
