使用自定义小部件填充 QListWidget

问题描述

我想创建一个包含许多这些项目的 QListView 或 QListWidget.我看过制作委托并使用 setItemWidget 来设置小部件.我在这两个方面都遇到了困难.

I would like to create a QListView or QListWidget that contains many of these items. I have looked at making delegates and also using setItemWidget to set the widget. I am having difficulties with both.

下面是在 QT Designer 中创建的，然后我有一个 UIC 文件，我将它加载到带有 uic.loadUi 的子类 QWidget 中，没有任何崩溃，但 listWidgetItems 为空.

This below was created in QT Designer, I then have a UIC file that I load in a subclassed QWidget with uic.loadUi, nothing is crashing, but the listWidgetItems are empty.

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.

Any help would be appreciated. I will be iterating on this below, so I would like to be able to load a UIC dynamically.

可能有数以千计的动画，所以如果可能的话，我想保持它的性能.

There could be thousands of animations, so I would like to keep it performant if possible.

推荐答案

所以，我不能用委托来做，但这里是通过加载从 QtDesigner 生成的自定义小部件加载到 listView 中的代码使用 setItemWidget:

So, I couldn't do it with a delegate, but here's the code for doing it with loading a custom widget generated from QtDesigner that is loaded into the listView with setItemWidget:

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!'

class animItemWidget(QtGui.QWidget):

    def __init__(self, parent=None):
        super(animItemWidget, self).__init__()

        self.button04.setObjectName(QtCore.QString.fromUtf8("button04"))
        self.horizontalLayout.addWidget(self.button04)
        self.button03 = QtGui.QPushButton(self)
        self.button03.setMaximumSize(QtCore.QSize(24, 24))

        self.connect(self.button02, QtCore.SIGNAL("clicked()"), self.awesome)

    def awesome(self):
        print self.label.text() + ' is awesome!'


if __name__ == "__main__":
    app = QtGui.QApplication(sys.argv)
    win = uiControlTest()
    sys.exit(app.exec_())
