Python PyQt5.QtCore 模块，QSortFilterProxyModel() 实例源码
我们从Python开源项目中，提取了以下3个代码示例，用于说明如何使用PyQt5.QtCore.QSortFilterProxyModel()。
def __init__(self, parent, data=None):
super(ListFrame, self).__init__(parent, data_manager=data)
self.ui = topics_list.Ui_topicsList()
self.ui.setupUi(self)
self._filter = QtCore.QSortFilterProxyModel()
self._model = ListModel(self.data.idea_names.values(), self)
self._onselect_listener = listener.Listener()
self._filter.setSourceModel(self._model)
self.ui.listWidget.setModel(self._filter)
self.ui.listWidget.selectionModel().selectionChanged.connect(self._on_select_model)
self.ui.filterText.textEdited.connect(self._filter.setFilterFixedString)
def setModel(self, model):
smodel = QtCore.QSortFilterProxyModel(parent=self)
smodel.setSourceModel(model)
ret = super(VqtView, self).setModel(smodel)
c = len(model.columns)
for i in range(c):
self.resizeColumnToContents(i)
return ret
def __init__(self, parent=None):
super(AdvComboBox, self).__init__(parent)
self.setFocusPolicy(QtCore.Qt.StrongFocus)
self.setEditable(True)
# add a filter model to filter matching items
self.pFilterModel = QSortFilterProxyModel(self)
self.pFilterModel.setFilterCaseSensitivity(QtCore.Qt.CaseInsensitive)
self.pFilterModel.setSourceModel(self.model())
# add a completer, which uses the filter model
self.completer = QCompleter(self.pFilterModel, self)
# always show all (filtered) completions
self.completer.setCompletionMode(QCompleter.UnfilteredPopupCompletion)
self.setCompleter(self.completer)
# connect signals
def filter_function(text):
self.pFilterModel.setFilterFixedString(str(text))
self.lineEdit().textEdited.connect(filter_function)
self.completer.activated.connect(self.on_completer_activated)
# on selection of an item from the completer, select the corresponding item from combobox
