2

。清除网格布局中的所有小部件...

3

。最后根据tat特定文件夹中文件和文件名的数量重新创建我的所有小部件，例如添加小部件并刷新库..，但顺序与之前相同。.]]

        Files = self.getfiles_by_Date(Path)

            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功能，可以按创建日期对文件夹文件进行排序..现在我的网格布局以正确的顺序排列我的按钮..但是按钮的位置在跳跃..就像它们之间的缝隙..我已经上传了我的屏幕截图也

从布局中删除所有小部件看起来像这样：

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()
