我正在嘗試創建自定義小部件列表，用戶單擊它們以打開圖片/電影。我一切正常，但我失去了通常隨項目一起出現的選擇突出顯示。我知道它不在那里，因為我使用的是自定義小部件。如何在小部件上獲得選擇突出顯示？我希望該項目顯示一層透明的藍色。奇怪的是，當我將視圖模式更改為列表模式時，您可以看到藍色選擇。我已經在示例代碼中注釋掉了它。他是一個條紋背的例子，以及條紋背，因為我無論如何都能得到它。切換列表視圖并選擇一個項目以查看不同的行為。import sysfrom datetime import datetimefrom PyQt5 import QtWidgetsfrom PyQt5 import QtCorefrom PyQt5 import QtGuiclass EntryWidget(QtWidgets.QWidget): def __init__(self): super(EntryWidget, self).__init__() self.setCursor(QtGui.QCursor(QtCore.Qt.PointingHandCursor)) # controls self.thumbnail = QtWidgets.QLabel() self.version = QtWidgets.QLabel() self.date = QtWidgets.QLabel() self.name = QtWidgets.QLabel() self.name.setAlignment(QtCore.Qt.AlignCenter) self.author = QtWidgets.QLabel() self.author.setAlignment(QtCore.Qt.AlignRight) self.dummy = QtWidgets.QLabel(" ") # layout main_layout = QtWidgets.QVBoxLayout() main_layout.setContentsMargins(0, 0, 0, 0) main_layout.setSpacing(0) main_layout.addWidget(self.name) main_layout.addWidget(self.thumbnail) main_layout.addWidget(self.version) main_layout.addWidget(self.date) main_layout.addWidget(self.author) main_layout.addWidget(self.dummy) main_layout.addStretch() self.setLayout(main_layout) def set_size(self, w, h): self.thumbnail.setFixedSize(w, h) def set_version(self, name): self.version.setText(" Version:" + str(name)) def set_date(self, name): date_string = " Date: {0}/{1}/{2}\n Time: {3}:{4}:{5}".format( str(name.day).zfill(2), str(name.month).zfill(2), name.year, name.hour, name.minute, name.second) self.date.setText(date_string) def set_name(self, name): self.name.setText(name) def set_author(self, name): self.author.setText(name + " ")

好吧，我已經找到了一種行之有效的方法。我在QListWidgetItem中添加了一些空白文本，并使字體變得非常大。這帶回了項目的突出顯示。
media_item.setText(" ") # set the item with a dummy string
media_item.setFont(QFont('Verdana', 180)) # make the font big so it covers the whole widget
經過一些研究，我發現使用QListView和Q代表是做到這一點的方法。我找不到使用PyQt5的好例子/教程，所以我現在只使用它。
這是代碼
