Question

这是我上一个问题的延续。“如何从左上角开始向gridlayout添加小部件”，感谢 X.Jacobs 来解决问题问题.. 现在我想删除所有窗口小部件并以相同的顺序重新创建相同的窗口小部件，例如刷新窗口小部件库。感谢

好的，这是我的ui ..当我点击createPose按钮时，它将调用3 Def ..

1 即可。在特定文件夹中创建一个txt文件

2 即可。清除网格布局中的所有小部件...

第3 即可。最后根据特定文件夹中的文件和文件名的数量重新创建我的所有小部件，例如添加小部件和刷新库..但是它的顺序与之前的顺序相同..

    self.connect(self.ui.CreatePose_pushButton, QtCore.SIGNAL("clicked()"), self.createPose)

def createPose(self):
            # To get Posename from UI
    self.__current_Posename = self.getPoseName()

    Path = 'D:\\PoseLibrary\\'

            # To Grab All files in tat Path
    Poses = self.findAllFiles(Path, '.xml')

    self.__NameSpace = self.ui.NameSpace_comboBox.currentText()

            #To find HighestTrailingNumber to Increment the file name
    if self.__current_Posename == "":
        newSuffix = self.findHighestTrailingNumber(Poses, self.__Default_Posename) + 1
        self.PoseName = self.__Default_Posename + str(newSuffix)
    else:
        self.PoseName = self.__current_Posename


    # Creating XML and Icon files
    open(Path + self.PoseName  + '.xml','w').close()

    icon = self.createIcon(self.PoseName, Path)
    # open(Path + self.PoseName  + '.png','w').close()


    self.refreshPoseLibrary(Path)
    self.ui.PoseName_lineEdit.clear()



def refreshPoseLibrary(self, Path ):
    # First Clear all my buttons in gridlayout
            self.deleteAll()

            # get all file fromm the path dir

    Files = self.getfiles_by_Date(Path)
    Poses = self.findAllFiles(Files, '.xml')

            # Create Btn 
    for Pose in Poses:
        icon = Path + Pose + '.png'
        self.icon.addPixmap(QtGui.QPixmap(icon), QtGui.QIcon.Normal, QtGui.QIcon.Off)
        self.button = QtGui.QPushButton('')
        self.button.setObjectName(Pose)
        self.buttonGroup.addButton(self.button)
        self.button.setIcon(self.icon)
        self.button.setIconSize(QtCore.QSize(128, 128))
        self.button.setMinimumSize(QtCore.QSize(128, 128))
        self.button.setMaximumSize(QtCore.QSize(128, 128))
        self.ui.gridLayout.addWidget(self.button)
        self.button.setContextMenuPolicy(QtCore.Qt.CustomContextMenu)
        self.connect(self.button, QtCore.SIGNAL('customContextMenuRequested(const QPoint&)'), self.popup)

def deleteAll(self):
    while self.ui.gridLayout.count():
        item = self.ui.gridLayout.takeAt(0)
        widget = item.widget()
        widget.deleteLater()


    def getfiles_by_Date(self, dirpath):
    Files = [s for s in os.listdir(dirpath)
         if os.path.isfile(os.path.join(dirpath, s))]
    Files.sort(key=lambda s: os.path.getmtime(os.path.join(dirpath, s)))
    return Files

现在我又添加了一个函数来按创建日期对文件夹文件进行排序..现在我的gridlayout以正确的顺序排列我的按钮..但是按钮的位置正在跳跃......就像它们之间的间隙...我有上传了我的屏幕截图

从布局中删除所有小部件如下所示：

while layout.count():
    item = layout.takeAt(0)
    widget = item.widget()
    # if widget has some id attributes you need to
    # save in a list to maintain order, you can do that here
    # i.e.:   aList.append(widget.someId)
    widget.deleteLater()
