hey everyone,

i recently ran into a MEL-problem for which i just can't find a solution...

e.g. you have something like the following:

string $test = "test";
...
...
...
button -command "bla($test)";

every time i try ro invoke the procedure "bla" (passing $test as an argument) by pressing the button Maya tells me that $test is an undeclared variable!

i really don't know what else to do since $test IS declared...

well, hope somebody can help me with that

cheers
MJ

basically you are passing $test as a string and not as a variable - if that is what you want i think you will have to declare $test as a global variable

global string $test;

or do you just want to assign bla's parameter from the variable $test the first time you create the button? - then you will have to properly escape it so that it's not taken literally but rather reads out the variable

Here's an example of properly escaping $test so it works..

string $test = "yeehaw";

button -command ("bla \"" + $yeehaw + "\"");

jason, thanx i'll try that out...i'm sure it works :-)

stunndman, i haven't tried out your suggestion yet, but i'm not too fond of global variables...they just take up memory :-) i'd be glad if there'd be another way :-) thanx anyway man

cheers

Jason, there is a small typo in your script, it should be:

button -command ("bla \"" + $test+ "\"");

but I guess M-J already figured that out ;)
