PyQt5 QListWidget自定义项目
PyQt5 QListWidget自定义项目
提问于 2020-02-05 18:48:10
我对PyQt5非常陌生，我正在尝试用python3+为qlistwidget制作一个自定义的qlistwidgetitem，但到目前为止还没有成功。
原来的代码，我喜欢并试图移植是从这个链接。不幸的是，它是用PyQt4编写的：
import sys
from PyQt4 import QtGui
class QCustomQWidget (QtGui.QWidget):
def __init__ (self, parent = None):
super(QCustomQWidget, self).__init__(parent)
self.textQVBoxLayout = QtGui.QVBoxLayout()
self.textUpQLabel = QtGui.QLabel()
self.textDownQLabel = QtGui.QLabel()
self.textQVBoxLayout.addWidget(self.textUpQLabel)
self.textQVBoxLayout.addWidget(self.textDownQLabel)
self.allQHBoxLayout = QtGui.QHBoxLayout()
self.iconQLabel = QtGui.QLabel()
self.allQHBoxLayout.addWidget(self.iconQLabel, 0)
self.allQHBoxLayout.addLayout(self.textQVBoxLayout, 1)
self.setLayout(self.allQHBoxLayout)
# setStyleSheet
self.textUpQLabel.setStyleSheet('''
color: rgb(0, 0, 255);
''')
self.textDownQLabel.setStyleSheet('''
color: rgb(255, 0, 0);
''')
def setTextUp (self, text):
self.textUpQLabel.setText(text)
def setTextDown (self, text):
self.textDownQLabel.setText(text)
def setIcon (self, imagePath):
self.iconQLabel.setPixmap(QtGui.QPixmap(imagePath))
class exampleQMainWindow (QtGui.QMainWindow):
def __init__ (self):
super(exampleQMainWindow, self).__init__()
# Create QListWidget
self.myQListWidget = QtGui.QListWidget(self)
for index, name, icon in [
('No.1', 'Meyoko', 'icon.png'),
('No.2', 'Nyaruko', 'icon.png'),
('No.3', 'Louise', 'icon.png')]:
# Create QCustomQWidget
myQCustomQWidget = QCustomQWidget()
myQCustomQWidget.setTextUp(index)
myQCustomQWidget.setTextDown(name)
myQCustomQWidget.setIcon(icon)
# Create QListWidgetItem
myQListWidgetItem = QtGui.QListWidgetItem(self.myQListWidget)
# Set size hint
myQListWidgetItem.setSizeHint(myQCustomQWidget.sizeHint())
# Add QListWidgetItem into QListWidget
self.myQListWidget.addItem(myQListWidgetItem)
self.myQListWidget.setItemWidget(myQListWidgetItem, myQCustomQWidget)
self.setCentralWidget(self.myQListWidget)
app = QtGui.QApplication([])
window = exampleQMainWindow()
window.show()
sys.exit(app.exec_())欢迎任何帮助。
