如何在Maya python中打印intField的值 [英] How to print the value of intField in Maya python

问题描述

我想使用python打印用户在maya中给定的intField的值.

I want to print the value of intField given by user in maya using python.

代码

import maya.cmds as cmds

def fun(number):
    print(number) 

cmds.window()
cmds.columnLayout()
num = cmds.intField(changeCommand = 'fun()')
cmds.showWindow()

用户将在intField中输入值，我想打印该值

User will enter value in intField and i want to print that value

推荐答案

您可以使用lambda或Partial，也可以仅在UI元素已经存在的范围内定义回调函数，以便知道UI的名称. :

You can use a lambda or partial, or you can simply define your callback function in a scope where the UI element already exists so it knows the name of the UI:

import maya.cmds as cmds

def fun(number):
    print(number) 

cmds.window()
cmds.columnLayout()
num = cmds.intField()
def num_callback():
    print cmds.intField(num, q=True, value=True)
cmds.intField(num, e=True, changeCommand = num_callback)
cmds.showWindow()

通常，您要避免使用回调分配的字符串形式:这是常见的问题根源，如果您不在侦听器中，则maya无法找到该函数. 此处

In general you want to avoid using the string form of callback assignment: it's a common source of problems where maya cannot find the function if you're not in the listener. More detail here
