我们从Python开源项目中,提取了以下7个代码示例,用于说明如何使用ctypes.wintypes.VARIANT_BOOL。
def test_variant_bool(self): from ctypes import wintypes # reads 16-bits from memory, anything non-zero is True for true_value in (1, 32767, 32768, 65535, 65537): true = POINTER(c_int16)(c_int16(true_value)) value = cast(true, POINTER(wintypes.VARIANT_BOOL)) self.assertEqual(repr(value.contents), 'VARIANT_BOOL(True)') vb = wintypes.VARIANT_BOOL() self.assertIs(vb.value, False) vb.value = True self.assertIs(vb.value, True) vb.value = true_value self.assertIs(vb.value, True) for false_value in (0, 65536, 262144, 2**33): false = POINTER(c_int16)(c_int16(false_value)) value = cast(false, POINTER(wintypes.VARIANT_BOOL)) self.assertEqual(repr(value.contents), 'VARIANT_BOOL(False)') # allow any bool conversion on assignment to value for set_value in (65536, 262144, 2**33): vb = wintypes.VARIANT_BOOL() vb.value = set_value self.assertIs(vb.value, True) vb = wintypes.VARIANT_BOOL() vb.value = [2, 3] self.assertIs(vb.value, True) vb.value = [] self.assertIs(vb.value, False)
