Is this possible?

[omkar-jere]

Suppose I have a very long script like 2000 lines or so now I want to split the script into 2 files.

1st File will hold all the UI.
2nd File will hold all the commands/procedures.

Now when I execute the command for the UI(Frm 1st File) I want to assign a procedure (frm 2nd File) to button. Is it possible ?

Yes thats how entire maya gui works for most parts.

You may use the same control name in any procedure without passing it. So it wont be a pblm(?), like:
button -l "Click Me" btn1;    in 1st File   and
button -e -c "runMe" btn1;   in 2nd File.

Thanks, I am learning MEL so getting a bit confused can you plz show me a simple example ?

[joojaa]

in one file:

 
... some gui code
button -c "somefunction();"
... some more gui code that shows the gui

in some other file, presimably named somefunction.mel if not must be sourced seprately

global proc somefunction(){
  print "something";
}

So:

A) guis dont need to know in advance what functions exist, they just eval strings.
B) fucntions will need to be loaded somehow for them to be called, if they arent loaded maya will TRY to fetch them form a appropriate file with same name as the function in question and look for a global proc of that name in the file. It does so by sourcing the file and then calling the function.
C) you gui can call nonexistent functrions, it does not matter for the builder. The error gets just dsplayed once the eval string f the gui item fails. Untill then its just text.

Thanks, Its working if I name the .mel file same as the procedure just one question now.

Say there are 2 procedures in the ,mel file first is "myProc1" (same name for the file) and second is "myProc2"(both are global ) I first execute "myProc1" using the UI it works fine, now I execute "myProc2" first time Maya gives an error second time works gr8 BUT if I execute "myProc2" without executing "myProc1" maya can't find that procedure. So is there any function/command that loads the procedures from a file into memory(not execute but load into memory) or any alternative for this kind of problem ?

source filenameWithoutExtension

pleas enote SOURCE is not a command its a directive so it does run FIRST irrespecitvely of where in the file it is!
