[GRASS-dev] testing tcltk animate

Glynn,

I took an initial look at the TclTk animator to replace xganim. I could get it started from the command line, but it only shows the display frame with buttons. I couldn’t see a way to add maps.

I also tried to run it from within the GUI by calling main. This returns an error " wrong # args: should be “main argc argv”.

So it needs to get passed something somewhere. What arguments is the program looking for to get started? A list of raster maps? Something else? I guess I should also ask, is ‘main’ the starting procedure?

Thanks
Michael

Thanks for looking into this. After a quick look, I became lost and realized I didn't even know where to start to try to run this.

It is supposed to accept the same options as xganim, i.e. view1=...
etc, where the value of each option is a list of raster maps separated
by commas.

Yes. The top level is a bunch of "set" commands, then a bunch of
"proc" commands, then a call to "main" on the last line. The
parse_command procedure deals with parsing the command line.
