我在 Pyside 工作。每次我重新打开窗口时，它都会弹回屏幕中间。如何让 Maya 或 Windows 记住位置和大小？

这是我正在使用的一些基本代码：

import traceback
from PySide import QtCore
from PySide import QtGui
from shiboken import wrapInstance
import maya.cmds as cmds
import maya.OpenMayaUI as omui
import pymel.core as pm
import maya.cmds as cmds

def maya_main_window():
     '''
     Return the Maya main window widget as a Python object
     '''
     main_window_ptr = omui.MQtUtil.mainWindow()
     return wrapInstance(long(main_window_ptr), QtGui.QWidget)

class TestTool(QtGui.QDialog):


 def __init__(self, parent=maya_main_window()):
      super(TestTool, self).__init__(parent)
      self.qtSignal = QtCore.Signal()
      #################################################################
 def create(self):
     '''
      Set up the UI prior to display
      '''
      self.setWindowTitle("Test")
      self.setWindowFlags(QtCore.Qt.Tool)
      #self.resize(400, 250) # re-size the window
     self.setGeometry(650, 200, 600, 300)
      self.setFixedHeight(580)
      self.setFixedWidth(300)

      QtGui.QToolTip.setFont(QtGui.QFont('SansSerif', 10))




if __name__ == "__main__":
     try:
          ui.deleteLater()
     except:
          pass
     ui = TestTool()
     try:
          ui.create()
          ui.show()
     except:
          ui.deleteLater()
          traceback.print_exc()

【解决方案1】：

您可以使用的一个选项是QWidget.saveGeometry() 和QWidget.restoreGeometry()。有了这个，您可以在工具关闭时保存窗口的位置和大小，然后在初始化时将其恢复。

通常对于像这样保存工具状态的东西，我会将数据存储到带有QtCore.QSettings 的某个位置的ini 文件中。这样，即使您关闭 Maya 或运行多个会话，它也会恢复到上一个状态。

这是一个例子：

import traceback
from PySide import QtCore
from PySide import QtGui
from shiboken import wrapInstance
import maya.cmds as cmds
import maya.OpenMayaUI as omui
import pymel.core as pm
import maya.cmds as cmds
import os

def maya_main_window():
    '''
    Return the Maya main window widget as a Python object
    '''
    main_window_ptr = omui.MQtUtil.mainWindow()
    return wrapInstance(long(main_window_ptr), QtGui.QWidget)

class TestTool(QtGui.QDialog):

    def __init__(self, parent=maya_main_window()):
        super(TestTool, self).__init__(parent)
        self.qtSignal = QtCore.Signal()

        # Using an env variable makes the path more generic, but use whatever you want
        self.settings_path = os.path.join(os.getenv('HOME'), "settingsFile.ini")

        #################################################################

    def create(self):
        '''
        Set up the UI prior to display
        '''
        self.setWindowTitle("Test")
        self.setWindowFlags(QtCore.Qt.Tool)
        self.resize(400, 250) # re-size the window
        self.setGeometry(650, 200, 600, 300)
        self.setFixedHeight(580)
        self.setFixedWidth(300)

        QtGui.QToolTip.setFont(QtGui.QFont('SansSerif', 10))

        # Restore window's previous geometry from file
        if os.path.exists(self.settings_path):
            settings_obj = QtCore.QSettings(self.settings_path, QtCore.QSettings.IniFormat)
            self.restoreGeometry(settings_obj.value("windowGeometry"))

    def closeEvent(self, event):
        # Save window's geometry
        settings_obj = QtCore.QSettings(self.settings_path, QtCore.QSettings.IniFormat)
        settings_obj.setValue("windowGeometry", self.saveGeometry())

if __name__ == "__main__":
    try:
        ui.deleteLater()
    except:
        pass

    ui = TestTool()

    try:
        ui.create()
        ui.show()
    except:
        ui.deleteLater()
        traceback.print_exc()

由于您将大小设置为固定，这只会影响位置。希望对您有所帮助！
