使用自定义窗口小部件填充QListWidget

Question

我想创建一个包含许多这些项的QListView或QListWidget。 我已经看过做代表，也使用过setItemWidget来设置小部件。 我都遇到困难。

下面是在QT Designer中创建的，然后有一个UIC文件，该文件使用uic.loadUi加载到子类QWidget中，没有崩溃，但listWidgetItems为空。

任何帮助，将不胜感激。 我将在下面对此进行迭代，因此我希望能够动态加载UIC。

可能会有成千上万的动画，因此，我希望尽可能保持其高性能。

因此，我无法使用委托来执行此操作，但是以下代码用于加载从QtDesigner生成的自定义小部件，并使用setItemWidget将其加载到listView中：

import os, sys
import xml.etree.ElementTree as et
from PyQt4 import QtGui, QtCore, uic

class uiControlTest(QtGui.QMainWindow):
    def __init__(self):
        super(uiControlTest, self).__init__()
        self.ui = uic.loadUi('uiControlTest.ui')
        self.ui.show()

        for i in range(0,300):
            wid = animItemWidget()
            wid.label_2.setText('Last edited by chrise @2014.06.21:23:17')
            wid.label.setText('Animation ' + str(i) + '       ')

            wid2 = QtGui.QListWidgetItem()
            wid2.setSizeHint(QtCore.QSize(100, 40))
            self.ui.list.addItem(wid2)
            self.ui.list.setItemWidget(wid2, wid)

        def awesomeButtonPressed():
            print 'awesome!'
