示例1: testCurrentFilterExpression
# 需要导入模块: from qgis.gui import QgsAttributeFormEditorWidget [as 别名]
# 或者: from qgis.gui.QgsAttributeFormEditorWidget import currentFilterExpression [as 别名]
def testCurrentFilterExpression(self):
""" Test creating an expression using the widget"""
layer = QgsVectorLayer("Point?field=fldint:integer", "test", "memory")
parent = QWidget()
w = QgsDefaultSearchWidgetWrapper(layer, 0, parent)
af = QgsAttributeFormEditorWidget(None, None)
af.setSearchWidgetWrapper(w)
# test that filter combines both current value in search widget wrapper and flags from search tool button
w.lineEdit().setText('5.5')
af.searchWidgetToolButton().setActiveFlags(QgsSearchWidgetWrapper.EqualTo)
self.assertEqual(af.currentFilterExpression(), '"fldint"=5.5')
af.searchWidgetToolButton().setActiveFlags(QgsSearchWidgetWrapper.NotEqualTo)
self.assertEqual(af.currentFilterExpression(), '"fldint"<>5.5')示例2: testBetweenFilter
# 需要导入模块: from qgis.gui import QgsAttributeFormEditorWidget [as 别名]
# 或者: from qgis.gui.QgsAttributeFormEditorWidget import currentFilterExpression [as 别名]
def testBetweenFilter(self):
""" Test creating a between type filter """

af = QgsAttributeFormEditorWidget(None, form)
af.createSearchWidgetWrappers("DateTime", 0, {})
d1 = af.findChildren(QDateTimeEdit)[0]
d2 = af.findChildren(QDateTimeEdit)[1]
d1.setDateTime(QDateTime(QDate(2013, 5, 6), QTime()))
d2.setDateTime(QDateTime(QDate(2013, 5, 16), QTime()))
af.searchWidgetToolButton().setActiveFlags(QgsSearchWidgetWrapper.Between)
self.assertEqual(af.currentFilterExpression(), '"fldtext">=\'2013-05-06\' AND "fldtext"<=\'2013-05-16\'')
af.searchWidgetToolButton().setActiveFlags(QgsSearchWidgetWrapper.IsNotBetween)
self.assertEqual(af.currentFilterExpression(), '"fldtext"<\'2013-05-06\' OR "fldtext">\'2013-05-16\'')
