python - Maya PySide 窗口 - 记住位置和大小

Question

我在 Pyside 工作。每次我重新打开窗口时，它都会弹回到屏幕中间。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()

您可以使用的一个选项是QWidget.saveGeometry() 和QWidget.restoreGeometry()。这样，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内容，我会将数据存储到带有 QtCore.QSettings 的 ini 文件中。这样，即使您关闭 Maya 或运行多个 session ，它也会恢复到最后的状态。

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()

由于您将尺寸设置为固定，因此这只会影响位置。希望对您有帮助!
