Update a string with procedure - Issue

[t.pansiot]

Hi, 

Here is my issue, I want to create a tool to change a string Value:

Theoric Example:   Variable called  "Name One"

Click on the tool to update Variable in "Name Two"

MEL Script:

string $Target = "NAME_ONE";

string $window = `window -title "Long Name"
-iconName "Short Name"
-widthHeight 200 55`;
columnLayout -adjustableColumn true;
button -label "Change Name" -command "NewName($Target)";
button -label "Close" -command ("deleteUI -window " + $window);
setParent ..;
showWindow $window;

proc NewName(string $Target){
$Target = "NAME_TWO";
print $Target;
}

print $Target;

During the procedure, it seems to work, nut as soon as I print $Target again, it remains, "Object_One"

Anyone would know a trick?

Hi!

Try something like this:

global proc string NewName(string $name){
$name = "NAME_TWO";
return $name;
}

NewName("whatever");
print `NewName("whatever")`;
print (NewName("whatever"));

Here is the solutions: string should be "global string" and it should be called inside the proc like this:

global string $Target = "NAME_ONE";

string $window = `window -title "Long Name"
-iconName "Short Name"
-widthHeight 200 55`;
columnLayout -adjustableColumn true;
button -label "Change Name" -command "NewName()";
button -label "Close" -command ("deleteUI -window " + $window);
setParent ..;
showWindow $window;

global proc NewName(){
global string $Target ;
$Target = "NAME_TWO";
print $Target;
}

print $Target;

Hi!

Yes I tested this too and it did not work, but I guess this was, because I had already declared the variable based on your example code and would have needed to close and reopen Maya.
