Maya for 3D Printing - Rapid Prototyping
In this course we're going to look at something a little different, creating technically accurate 3D printed parts.

syntax?
global proc editAttrPopup ()
{
$currentObj = `ls -sl`;
print($currentObj);
string $currentAttrMin = ($currentObj + ".up_Filter_Size");
window -menuBar true -maximizeButton false -title "Edit_Attribute" -iconName "editAttrPopupI" -w 200 -h 150 PopEditAttrB_w;
columnLayout;
rowColumnLayout -numberOfRows 2;
showWindow PopEditAttrB_w;
}
Thanks.

The ls command returns always a string array. So you should do something like this:
string $currentObj[] = `ls -sl`;
Now let's say you're interested on the first object in the selection (index 0).
print($currentObj[0]);
The other thing is that in a script, you need to use the getAttr command to retrieve a value of an attribute. Like this:
string $currentAttrMin = getAttr($currentObj + ".up_Filter_Size");
You might want to also check the data type of the up_Filter_Size. Something tells me that it's not a string (although the above will propably work due to the automatic type conversion).

What it does is it builds a menu based on whatever user created attributes are on your object. Down the road, I'm going to try and read the min/max values of those attributes, and place those values in a field. Then there will be an edit button so I can change the min/max values of each attribute. I have a script that does that, so I'm just working on the interface.
What I am currently stuck on is when I run the script and change the menu selection, I can't get anything to happen. I tried the -command function on the menuItem, but it doesn't work when in optionMenu. I cannot figure out the syntax of the -cc function on the optionMenu, and while the docs claim it runs every time you change your selection, it does not.
global proc optMenu()
{
string $currentObj[] = `ls -sl`;
string $currentObjAttr[]= `listAttr -ud ($currentObj[0])`;
string $currentAttr = ($currentObj[0] +"."+ $currentObjAttr[0]);
int $counter = 0;
string $selected = $currentObjAttr[0];
// string $changeSelected = "print("+$selected+")";
window -menuBar true -maximizeButton false -title "Option Menu" -iconName "optMenu_I" -w 200 -h 150 optMenu_w;
columnLayout;
rowColumnLayout -numberOfRows 3;
optionMenu -label "Attributes" -cc "($selected = $currentObjAttr[$counter])";
while ($currentObjAttr[$counter] != "")
{
menuItem -label $currentObjAttr[$counter];
$counter +=1;
}
showWindow optMenu_w;
}
Thanks again for the help. Attached is a very simple Maya file you can use to test the script in you are so inclined.
