Proc Call From Button

[doug-hines]

I have been attempting to pass a variable from my GUI to a global proc but I feel like I have been going in circles with the syntax.

CODE
        string $jointNodes[] = listRelatives -c Root\_joint;
        string $alignWin = window -title "Scene ReSkin" -mxb 0 -mnb 0 peVehReSkin;
        columnLayout -w 800 -h 125 -cal "center"; // Container Layout
            button -label "De-skin Scene" -w 150 -c ("stripSkin" + $jointNodes);
            separator -w 150 -h 10;
            button -label "Re-skin Scene" -w 150 -c ("reSkin" + $jointNodes);
                               showWindow $alignWin;

I get errors varying from "Illegal operation "+" on data of type string[]
to the annoying simple and useless "syntax error: line blah.blah"

I know this is a simple concatenation error, but at this point, my brain is mush. Any help would be appreciated.

you created $jointNodes as an array!
so if you try ("stripSkin" + $jointNodes) maya throws an error. Of course!

in such case you have to declare wich element of the array you actually want:
CODE
{
     string $jointNodes[] = listRelatives -c Root\_joint;

     string $alignWin = window -title "Scene ReSkin" -mxb 0 -mnb 0 peVehReSkin;
         columnLayout -w 800 -h 125 -cal "center";
             button -label "De-skin Scene" -w 150 -c ("stripSkin" + $jointNodes[0]);
             separator -w 150 -h 10;
             button -label "Re-skin Scene" -w 150 -c ("reSkin" + $jointNodes[0]);
     showWindow $alignWin;
}

listRelatives returns a list and for ovious reasons concatenating a straing with a alist makes little sense. however you could just do:

$jointNodes[0]

instead

[doug-hines]

I do realize that you cannot concatenate an array and a string. However, I am under the impression that using $jointNodes[0] will send only the first item of the list, hence the [0]. I need the send the whole list

I have the following setup for a test:
joint1
|-joint2
|-joint3
|-joint4
|-joint5

Each of the global procs are set up the catch the entire array :

CODE
global proc stripSkin(string $nodes[])
{
print $nodes;
}

Using your example, I recieved the error: Cannot find procedure "stripSkinjoin2"

You cant send in a list unless its a global variable off course (or tokenize it). However its much saner if you do your gui the other way around.

So instead of doing the listRelatives before press do it after, if its imperative that the node not change form start put in the startup thing into some container.

Its not purposeful to make guis that are static.

[doug-hines]

I am not sure I understand what you mean by container. What do you mean by container?

I was just trying to fix your first error and thought you might have noticed that YOU named your command stripSkin!
Doh!!
Ah you said stripSkinjoin2! OK thats because there is no "space" between the strings:

CODE
-------------------------space-goes-there--->>>v
button -l "De-skin Scene" -w 150 -c ("stripSkin " + $jointNodes[0]);

Know what I mean?
And Joojaa means you are putting your stuff in the UI before you perform the action!
So the UI is the container for the data! Wich is a bad way to do things. Especially when handling arrays!

You can do this much better if you get your [b]listRelatives -c Root\_joint[/b] IN the procedure you call when pushing the button.
So that the button line looks like:
CODE
button -l "De-skin Scene" -w 150 -c "stripSkin;";
