Thanks Justin for your answer! This trick with nested formatting {}
utilizing map function is really neat! :D Well, about the second point
though, unfortunately for me OOP is still some sort of black magic I just
can't understand. So I write small script that should emulate my bigger
tool just to test and learn things you said about this "refactoring the
code into a class".
class MyWindow(object) :
def __init__(self) :
self.curMoveVal = cmds.manipMoveContext('Move', query=True,orientAxes
=True)
def updateText(self, *args) :
return self.curMoveVal
def caoidWin(self) :
testWindow = 'someName'
if cmds.window(testWindow, ex=True) :
cmds.deleteUI(testWindow, window=True)
testWindow = cmds.window(
testWindow,
title='testWindow',
wh=(400,200))
cmds.columnLayout(
adjustableColumn=True,
rowSpacing=10)
cmds.text(
l='{0}'.format(self.updateText()))
cmds.button(
l='Apply',
c=self.updateText)
cmds.showWindow(testWindow)
a = MyWindow()
a.caoidWin()
Sorry if it doesn't make sense (as I said - I'm currently in a stone age
with my programming skills). In this script my point was to just update
what I have currently stored in Move Custom axis orientation after clicking
"Apply"... and only that, no converting into degrees or other fancy things.
But even with this simple task I failed and overall I don't know how
approach this problem. First of all I don't know what to write into label='
' in cmds.text to make it update each time.
