Question

我想在Maya Graph编辑器中添加一些新按钮 - 特别是在Channel列表的顶部，窗口左侧有所有属性。但是，我宁愿不使用Graph Editor本身的Maya Startup脚本。有没有办法在每个新的Graph Editor窗口中使用单独的脚本“父”我想要的新按钮？

理想情况下，这可能是所有Python。

<强> TL; DR;

if cmds.window("GE_ui_window", exists=True): #If the window exists
    cmds.deleteUI("GE_ui_window") #Delete it
cmds.window("GE_ui_window", title="My custom Graph Editor") #Create your custom win

cmds.frameLayout("GE_ui_frameLayout", p="GE_ui_window", lv=False, bv=False ) 

if cmds.scriptedPanel("GE_ui_scriptedPanel", exists=True): #If the scriptel panel already exists
    cmds.deleteUI("GE_ui_scriptedPanel") #Delete it
cmds.scriptedPanel("GE_ui_scriptedPanel", unParent=True, type="graphEditor")
cmds.scriptedPanel( "GE_ui_scriptedPanel", e=True, parent="GE_ui_window|GE_ui_frameLayout") #parent the scripted panel to your frame layout

cmds.showWindow("GE_ui_window")

channelLayout = cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", query=True, ca=True)[0] #Get the channel box's layout
filterLayout = cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", query=True, ca=True)[1] #Get the filter's layout

myRowLayout=cmds.rowLayout(numberOfColumns=3, p="GE_ui_scriptedPanelOutlineEdForm") #Create a row layout 
cmds.button(label="Café", h=100, p=myRowLayout) #Add some buttons
cmds.button(label="Clope", p=myRowLayout)
cmds.button(label="Caca", p=myRowLayout)

#This will reorder the content of the left formLayout
cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", edit=True, af=[ \
            (channelLayout, "bottom", 0), \
            (channelLayout, "right", 0),  \
            (filterLayout, "top", 0),  \
            (myRowLayout, "left", 0),  \
            (myRowLayout, "right", 0)],  \
            ac=[(myRowLayout, "top", 0, filterLayout), \
            (channelLayout, "top", 0, myRowLayout)])

在编辑Maya的UI时，有两个非常有用的事情要知道。

首先是脚本编辑器中的History -> Echo all commands复选框。这可以打印出大量垃圾，里面有用的信息。

第二件事是whatIs命令（Doc）。

此命令采用一个字符串类型参数并返回一个字符串指示参数是否是内置的“命令”，“梅尔过程“，”脚本“或变量。如果是变量，则为类型变量也给出了。如果参数是Mel程序或者脚本文件，包含脚本或过程的文件的路径包含在返回值中。

此组合将允许您跟踪图形编辑器的创建方式和位置。现在我们来做吧。

1：打开图表编辑器Window -> Animation Editors -> Graph Editor

GraphEditor;
tearOffPanel "Graph Editor" "graphEditor" true;
// Result: graphEditor1Window //

GraphEditor;是一个运行时命令，在调用时执行tearOffPanel "Graph Editor" "graphEditor" true;。这就是它出现在脚本编辑器中的原因。

2：运行whatIs "tearOffPanel";（mel）

// Result: Mel procedure found in: C:/Program Files/Autodesk/Maya2014/scripts/startup/tearOffPanel.mel //

通过对此文件的一些调查，您可以推断出可以使用scriptedPanel命令创建一个全新的图形编辑器。

3：创建自己的图表面板

scriptedPanel doc向您展示如何创建脚本面板并将其包含在窗口中。您现在可以使用以下方法创建自定义图形编辑器：

if cmds.window("GE_ui_window", exists=True):
    cmds.deleteUI("GE_ui_window")
cmds.window("GE_ui_window", title="My custom Graph Editor")

cmds.frameLayout("GE_ui_frameLayout", p="GE_ui_window", lv=False, bv=False )

if cmds.scriptedPanel("GE_ui_scriptedPanel", exists=True):
    cmds.deleteUI("GE_ui_scriptedPanel")
cmds.scriptedPanel("GE_ui_scriptedPanel", unParent=True, type="graphEditor", label='Sample')
cmds.scriptedPanel( "GE_ui_scriptedPanel", e=True, parent="GE_ui_window|GE_ui_frameLayout")

cmds.showWindow("GE_ui_window")

4：尝试了解图表编辑器的构建方式

此脚本将打印出Graph Editor的小部件层次结构（首先创建自定义Graph Editor）：

nbIteration = 0
def getChildren(uiItem, nbIteration):
    for childItem in cmds.layout(uiItem, query=True, childArray=True):
        try:
            print "|___"*nbIteration + childItem
            getChildren(uiItem + "|" + childItem, nbIteration+1)
        except:
            pass
getChildren("GE_ui_window|GE_ui_frameLayout|GE_ui_scriptedPanel", nbIteration)

另外，您可以查看C:\Program Files\Autodesk\Maya2014\scripts\others\graphEditorPanel.mel，@939: global proc addGraphEditor (string $whichPanel)

你现在可以意识到很多小部件都没有给出任何名称，只有Maya给出的默认名称。因此，我们无法使用完整路径添加小部件和父级，因为每次创建新的Graph Editor时此路径都会更改。

我们将依赖的项目是GE_ui_scriptedPanelOutlineEdForm，formLayout包含其他formLayout和paneLayout。

|___|___GE_ui_scriptedPanelOutlineEdForm 
|___|___|___paneLayout123 #layout containing the two channel boxes
|___|___|___|___GE_ui_scriptedPanelOutlineEd
|___|___|___|___GE_ui_scriptedPanelOutlineEdSlave
|___|___|___formLayout276 #Layout containing the "filter part"
|___|___|___|___textField63 #It's text
|___|___|___|___iconTextButton102

5：创建按钮并重新排序GE_ui_scriptedPanelOutlineEdForm的内容

channelLayout = cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", query=True, ca=True)[0] #Get the channel box's layout
filterLayout = cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", query=True, ca=True)[1] #Get the filter's layout

myRowLayout=cmds.rowLayout(numberOfColumns=3, p="GE_ui_scriptedPanelOutlineEdForm") #Create a row layout 
cmds.button(label="Café", h=100, p=myRowLayout) #Add some buttons
cmds.button(label="Clope", p=myRowLayout)
cmds.button(label="Caca", p=myRowLayout)

#This will reorder the content of the left formLayout
cmds.formLayout("GE_ui_scriptedPanelOutlineEdForm", edit=True, af=[ \
            (channelLayout, "bottom", 0), \
            (channelLayout, "right", 0),  \
            (filterLayout, "top", 0),  \
            (myRowLayout, "left", 0),  \
            (myRowLayout, "right", 0)],  \
            ac=[(myRowLayout, "top", 0, filterLayout), \
            (channelLayout, "top", 0, myRowLayout)])

为此，您可能必须使用PySide / PyQt。找到图形编辑器的指针，找到元素的布局方式。

以下是有关更改maya菜单样式表的示例：

from maya.OpenMayaUI import MQtUtil as omui
import sip
from PyQt4 import QtGui

def changeMayaMenuColors(fontStyle='italic', fontWeight='bold', fontColor='cyan'):
    # Get the widget
    widgetStr = mel.eval( 'string $tempString = $gMainCreateMenu' )
    ptr = omui.findControl( widgetStr )
    widget = sip.wrapinstance(long(ptr), QtGui.QWidget)
    widget.setStyleSheet('font-style:%s;'%fontStyle +'font-weight:%s;'%fontWeight + 'color:%s;'%fontColor)

这里有关于channelBox的sonme实验：

from PySide import QtGui, QtCore
from shiboken import wrapInstance
from maya.OpenMayaUI import MQtUtil


channelbox = wrapInstance(long(MQtUtil.findControl('mainChannelBox')), QtGui.QWidget)
channelbox_children = channelbox.children()

first_widget = channelbox_children[0] # EDIT
first_widget.hide()
#first_widget.show()
#---------------------------------------------------------------------------------------------------------------
mySubWdget = first_widget.children()

new_button = QtGui.QPushButton()
new_layout = QtGui.QVBoxLayout()
first_widget.setLayout(new_layout)
new_layout.addWidget(new_button)

def print_hodor():
    print 'HODOR'

new_button.clicked.connect(print_hodor)

你可以用所有maya小部件进行这项实验：找到指针，然后使用wrapInstance获取QT指针，然后遍历子项以找到你可能想要的布局。
