（Maya Python）如何通过GUI函数运行单选选项按钮？

Question

通常，当我使用单选按钮选项运行脚本时，您选择一个单选按钮选项，然后使用按钮激活它。我曾经将菜单gui放在函数之外：但自从我学会导入maya脚本后，我开始将菜单界面包装在gui函数中，这意味着我的单选按钮技术现在不再有效。我也不知道如何让它工作。脚本本身非常简单：导入脚本后只需选择一个单选按钮选项，然后使用按钮创建一个形状：至少它应该是这样工作的。相反，我没有错误，也没有创建任何形状，我不知道什么东西坏了

'''
import cubeTestTemp
reload (cubeTestTemp)
cubeTestTemp.gui()
'''

import maya.cmds as cmds

#Creates ui. 
if cmds.window("cubeWin", exists =True):
    cmds.deleteUI("cubeWin", window = True)

myWindow = cmds.window("cubeWin",t='DS shapeDemo V1',w=200, h=500, toolbox=True)
column = cmds.columnLayout(adj=True)
#Creates variable to indicate the check box status. 1=Checked 0=Not Checked. 

cubeNum1 = 0
cubeNum2 = 0


#Creates Button funtion. 
def defaultButtonPush(*args):
       #The Print checks if button is pushed and what is the check box status. 
       print "Button is pushed."
       print cubeNum1
       #Check box argument finds the status of the variable and determines what to do. 
       #Eather create a cube or display a error dialog box.
       if cubeNum1 == 1:
        print "Cube Creation sucessful"
        cmds.polyCube()

       print "Button is pushed."
       print cubeNum2
       if cubeNum2 == 1:
        print "Sphere Creation sucessful"
        cmds.polySphere()


def gui(*args):
    #Creates check box. 
    #In the onCommand Script (onc) and offCommand Script (ofc) flags all commands must be made in between double quotes.
    cmds.radioCollection()
    cmds.radioButton(label='Cube',align='left',onCommand="cubeNum1 = 1", offCommand="cubeNum1 = 0")
    cmds.radioButton(label='Sphere',align='left',onCommand="cubeNum2 = 1", offCommand="cubeNum2 = 0")
    #Creates Button.
    cmds.button( label='Execute', command=defaultButtonPush ,align='left' )

cmds.showWindow()

这是修改后的脚本。问题在于脚本的范围。“onCommand”在其自己的范围内执行，该范围具有自己的“cubeNum”变量

"""
import cubeTestTemp
reload (cubeTestTemp)

"""

import maya.cmds as cmds

# Variable to indicate the radio button status. 1=Cube, 2=Shpere. 
shape_selector = 0


def action_button(*args):
    """
    Create an object based on the shape_selector status
    """
    print "Button is pushed", repr(args)
    if shape_selector == 1:
        cmds.polyCube()
        print "Cube created"
    elif shape_selector == 2:
        cmds.polySphere()
        print "Sphere created"
    else:
        print "No shape selected"


def selection_changed(shape):
    """
    Save the current shape selection
    into global variable "shape_selector"
    """
    global shape_selector
    shape_selector = shape
    print "Current selection:", shape_selector

    if cmds.window("cubeWin", exists=True):
        cmds.deleteUI("cubeWin", window=True)

    column = cmds.columnLayout(adj=True)
    # Create the radio buttons 
    cmds.radioCollection()
    cmds.radioButton(label='Cube',align='left', select=True, onCommand=lambda x:selection_changed(1))
    cmds.radioButton(label='Sphere',align='left', onCommand=lambda x:selection_changed(2))
    # Create the push button
    cmds.button(label='Create', command=action_button, align='left')
    cmds.showWindow()

if __name__ == "__main__":
    gui()

另一种方法是仅在需要时读取单选按钮状态

"""

reload (cubeTestTemp)
cubeTestTemp.gui()
"""

import maya.cmds as cmds


def action_button(cube_button, sphere_button):
    """

    """
    if cmds.radioButton(cube_button, query=True,select=True):
        cmds.polyCube()
        print "Cube created"
    elif cmds.radioButton(sphere_button, query=True,select=True):
        cmds.polySphere()
        print "Sphere created"
    else:
        print "No shape selected"


def gui():
    """
    Create the GUI
    """
    if cmds.window("cubeWin", exists=True):
        cmds.deleteUI("cubeWin", window=True)
    myWindow = cmds.window("cubeWin", t='DS shapeDemo V1', w=200, h=500, toolbox=True)
    column = cmds.columnLayout(adj=True)
    # Create the radio buttons 
    cmds.radioCollection()
    # Save the button ids
    cube_button = cmds.radioButton(label='Cube',align='left', select=True)
    sphere_button = cmds.radioButton(label='Sphere',align='left')
    # Create the push button
    cmds.button(label='Create', command=lambda x:action_button(cube_button, sphere_button), align='left')
    cmds.showWindow()

if __name__ == "__main__":
    gui()
