适用于Maya的Python-滑块颜色转换器

Question

我用Python为Maya编写了这个小脚本，其中有一个滑块，可以更改iconTextButton的背景颜色。运行脚本我没有任何警告或错误，但是它没有执行我上面解释的内容。

我不知道是什么问题，也许是我要在另一个函数中调用一个函数？ （当我在s_off（）中调用setColor（）时）。如果是此问题，我该如何解决？希望有人能帮助我

这里是代码：

import maya.cmds as cmds
from functools import partial

class ColorChangeWin(object):
    def __init__(self):
        self.buildWin()

    def buildWin(self):
        self.win = cmds.window(title="ColorChange")
        self.menuLayout = cmds.menuBarLayout()
        self.menu = cmds.menu(label="Window")
        self.menuItem = cmds.menuItem(label = "Close", command = partial(self.closeWin, self.win))
        self.mainlayout = cmds.columnLayout(adj = True)
        color = cmds.intSlider(min = 0, max = 3, value = 0,  step = 1, dc = partial(self.s_off), cc = partial(self.s_on), p = self.mainlayout)
        cmds.iconTextButton(w = 55, bgc = (0.467, 0.467, 0.467), p = self.mainlayout)
        cmds.showWindow(self.win)

    def closeWin(self, window = None, arg = None):
        if cmds.window(self.win, exists = True):
            cmds.deleteUI(self.win, window = True)


    def s_off(*args):
        panel = cmds.getPanel(withFocus=True)
        cmds.modelEditor(panel, e = True,  sel = False, m = False)
        return()
        setColor()

    def s_on(*args):
        panel = cmds.getPanel(withFocus=True)
        cmds.modelEditor(panel, e = True, sel = True, m = True)

    def setColor(*args):
        color_1 = cmds.intSlider(color, q = True, value = True)

        if color_1 == 0: 
            cmds.iconTextButton(e = True, bgc = (1, 1, 1))
        if color_1 == 1:
            cmds.iconTextButton(e = True, bgc = (0, 0, 1))
        if color_1 == 2:
            cmds.iconTextButton(e = True, bgc = (0.608, 0, 0.157))
        return 

ColorChangeWin()

有两件事：

• 您想念使用类，应该使用自我。当用户界面中其他地方使用了某些东西时，例如：窗口名称，滑块，彩色按钮
• 您在设置颜色之前要先退货，这样它就会退出

from functools import partial
import maya.cmds as cmds

class ColorChangeWin(object):
    def __init__(self):
        self.buildWin()

    def buildWin(self):
        self.win = cmds.window(title="ColorChange")
        cmds.menuBarLayout()
        menu = cmds.menu(label="Window")
        cmds.menuItem(label = "Close", command = partial(self.closeWin, self.win))
        main_layout = cmds.columnLayout(adj = True)
        self.color = cmds.intSlider(min = 0, max = 3, value = 0,  step = 1, dc = partial(self.s_off), cc = partial(self.s_on), p = main_layout)
        self.text_button = cmds.iconTextButton(w = 55, bgc = (0.467, 0.467, 0.467), p = main_layout)
        cmds.showWindow(self.win)

    def closeWin(self, window = None, arg = None):
        if cmds.window(self.win, exists = True):
            cmds.deleteUI(self.win, window = True)


    def s_off(self, *args):
        panel = cmds.getPanel(withFocus=True)
        cmds.modelEditor(panel, e = True,  sel = False, m = False)
        self.setColor()
        return

    def s_on(self, *args):
        panel = cmds.getPanel(withFocus=True)
        cmds.modelEditor(panel, e = True, sel = True, m = True)

    def setColor(self):
        color_1 = cmds.intSlider(self.color, q = True, value = True)

        if color_1 == 0: 
            cmds.iconTextButton(self.text_button, e = True, bgc = (1, 1, 1))
        if color_1 == 1:
            cmds.iconTextButton(self.text_button, e = True, bgc = (0, 0, 1))
        if color_1 == 2:
            cmds.iconTextButton(self.text_button, e = True, bgc = (0.608, 0, 0.157))
        return
ColorChangeWin()

您几乎得到了，只有几点注意事项：

1. 创建gui对象时，请不要忘记将它们捕获为变量并使用self，以便以后可以引用它们。
2. 在您的类中，该方法的所有第一个参数都应为self，除非您有意将其设为静态方法（然后需要添加装饰器）。如果您想了解更多信息，请快速进行Google搜索。
3. 无需在setColor中查询滑块的当前值，因为其changeCommand已经在其参数中提供了它。
4. 不太清楚s_off和s_on中要完成什么。由于所有接口项都已用self.存储，因此您已经可以从该类中的任何其他方法引用它们。

这是一个有效的示例：

import maya.cmds as cmds
from functools import partial


class ColorChangeWin(object):

    def __init__(self):
        self.buildWin()

    def buildWin(self):
        self.win = cmds.window(title="ColorChange")
        self.menuLayout = cmds.menuBarLayout()
        self.menu = cmds.menu(label="Window")
        self.menuItem = cmds.menuItem(label="Close", command=partial(self.closeWin, self.win))
        self.mainlayout = cmds.columnLayout(adj=True)
        self.color = cmds.intSlider(min=0, max=2, value=0, step=1, cc=partial(self.setColor), p=self.mainlayout)  # Add self.
        self.textButton = cmds.iconTextButton(w=55, bgc=(0.467, 0.467, 0.467), p=self.mainlayout)  # Capture in variable.
        cmds.showWindow(self.win)

    def closeWin(self, window=None, arg=None):
        if cmds.window(self.win, exists=True):
            cmds.deleteUI(self.win, window=True)

    def setColor(self, color_1):  # Add self as first parameter. No need to query the slider's value, as the 2nd parameter already has it from its changeCommand.
        if color_1 == 0: 
            cmds.iconTextButton(self.textButton, e=True, bgc=(1, 1, 1))
        if color_1 == 1:
            cmds.iconTextButton(self.textButton, e=True, bgc=(0, 0, 1))
        if color_1 == 2:
            cmds.iconTextButton(self.textButton, e=True, bgc=(0.608, 0, 0.157))
