Ok. firstly - I'm new to Python in Maya and my English is not so great
either so pardon me that ^^
While I was learning MEL and Python I came across this problem which I
can't figure out. So to be more clear I'll show my MEL code first and then
it's Python equivalent.
string $objAligner;
if (`window -ex $objAligner`) {
deleteUI -window $objAligner;
}
string $objAligner = `window -t "Object Alignment Tool" -s false -wh 300 100
-ret`;
columnLayout -adj true;
text -l "Instructions: select targets then affected object";
button -l "Execute" -w 300 -h 40 -c "aligner";
showWindow $objAligner;
proc aligner() {
string $prntCnstr = `parentConstraint`;
delete $prntCnstr;
}
import maya.cmds as mc
if mc.window(objAligner, ex=True) :
mc.deleteUI(objAligner, window=True)
objAligner = mc.window(title='Object Alignment Tool', s=False, wh=(300, 100),
ret=True)
mc.columnLayout(adj=True)
mc.text(l='Instructions: select targets then affected object')
mc.button(l='Execute', w=300, h=40, c='aligner()')
mc.showWindow(objAligner)
def aligner() :
prntCnstr = mc.parentConstraint()
mc.delete(prntCnstr)
So what I want to achieve is checking if window I have created is open and if
it is then I want to close it and create new one in the same place.
In MEL everything is ok because I can execute the first line of code without
anny errors: *string $objAligner;*
In Python though, we create variable when we assign value to a name so if I
open Maya and execute script shown above I get an error of undefined name
"objAligner".
Is there any way to solve this?
