アーティストのためのMaya Python入門 第１４回「ボタン付きGUIを作り、自作コマンドを登録してみよう！」

from maya import cmds

# buttonに登録するコマンド
def select_joints():
    nodes = cmds.ls(selection=True, dag=True)
    joints = []
    for node in nodes:
        if cmds.nodeType(node) == "joint":
            joints.append(node)
    cmds.select(joints)
    return None

# ボタン付きGUIの生成
button_window = cmds.window("hello_button_window")
button_layout = cmds.columnLayout(adjustableColumn=True, parent=button_window)
buttonA = cmds.button(label="Create Poly Sphere", command="cmds.polySphere()", parent=button_layout)
buttonB = cmds.button(label="Create Poly Cylinder", command="cmds.polyCylinder()", parent=button_layout)
buttonC = cmds.button(label="Select Joints", command="select_joints()", parent=button_layout)
cmds.showWindow(button_window)

# もし、ウインドウが生成できない場合調べる方法
cmds.lsUI(windows=True)
cmds.deleteUI("hello_button_window")
