删除workspaceControl/running uiScript，maya/pysid

Question

我在玛雅写了一件事，遇到麻烦了。真的不知道我做了什么，我要去做其他事情的时候，我做的最后一件事是在布局中添加一个按钮。 我已经在这方面乱搞了很长时间了，据我所知，uiScript标志不喜欢方法调用中传递的参数…？发生的是，它从不将还原标志设置为True，这样比特就不会命中。从而在maya中生成多个窗口。我也在想cmds.deleteUItry子句应该去，不一定在发生之前我在哪里有它。如果有人能提供任何见解，我将非常感激，干杯

在下面的脚本中，我用一个按钮替换了ui实例，它在行为上没有任何区别。

代码：

from PySide2 import QtWidgets, QtCore
from maya.app.general.mayaMixin import MayaQWidgetDockableMixin
import maya.OpenMayaUI as mui
import maya.cmds as cmds
import weakref

if not 'customMixinWindow' in globals():
    customMixinWindow = None

class DockableWidget(MayaQWidgetDockableMixin, QtWidgets.QWidget):


    instances = list()
    CONTROL_NAME = 'customMixinWindow'

    def __init__(self, parent=None):

        super(DockableWidget, self).__init__(parent=parent)

        DockableWidget.delete_instances()
        self.__class__.instances.append(weakref.proxy(self))
        self.main_layout = QtWidgets.QVBoxLayout()
        self.button = QtWidgets.QPushButton()
        self.main_layout.addWidget(self.button)
        self.setLayout(self.main_layout)
        self.setAttribute(QtCore.Qt.WA_DeleteOnClose)

    @staticmethod
    def delete_instances():
        print "deleting"
        for ins in DockableWidget.instances:
            try:
                ins.setParent(None)
                ins.deleteLater()
            except:
                pass
                DockableWidget.instances.remove(ins)
            del ins


def DockableWidgetUIScript(restore=False):

    global customMixinWindow

    if restore == True:
        restoredControl = mui.MQtUtil.getCurrentParent()

    customMixinWindow = DockableWidget()
    if customMixinWindow is None:
        #customMixinWindow = DockableWidget()
        customMixinWindow.setObjectName('customMayaMixinWindow')

    if restore == True:
        mixinPtr = mui.MQtUtil.findControl(customMixinWindow.objectName())
        mui.MQtUtil.addWidgetToMayaLayout(long(mixinPtr), long(restoredControl))

    else:
        try:
            cmds.workspaceControl('customMayaMixinWindowWorkspaceControl', e=True, close=True)
            cmds.deleteUI('customMayaMixinWindowWorkspaceControl')
        except:
            pass
        customMixinWindow.show(dockable=True, restore=True, height=400, width=400, uiScript='import dockWin; dockWin.DockableWidgetUIScript(restore=True)')

def main():

    ui = DockableWidgetUIScript()
    return ui


if __name__ == 'dockWin':
    main()

好的，问题解决了。 经过大量的故障排除，结果发现是我ui中的QSpacerItem导致窗口打开一次，然后第二次使maya崩溃。这让我觉得这和deleteUI有关。在

我添加了QSpacerItem，如下所示：

self.spacerFive = QtWidgets.QSpacerItem(5 , 5)
self.myLayout.addSpacerItem(self.spacerFive)

这使maya在删除UI/workspaceControl时完全崩溃… 不知道为什么，垃圾收集？在

这就解决了：

好了，一切又如期进行了。干杯
