如果我有:
struct LineChartScene::LineChartSceneImpl
{
enum ContextMenuAction {ShowLabels, ShowPoints, SaveAsImage};
};
如何在LineChartScene:LineChartSceneImpl:ContextMenuAction:ShowLabels
工作会奏效,但无。 I m using C++, Qt Publishing 2.2.1.

enum class Enum2 : unsigned int {Val1, Val2};
列举范围也界定为列举名称的范围。 采用数字名称要求进行明确的范围。 <><>>> 附件 Enum2:Val1 的定义。
此外,C++11将使旧式的列举能够提供明确的范围以及基本类型的定义:
enum Enum3 : unsigned long {Val1 = 1, Val2};
清单名称在列举范围( 代码>)中界定。 Enum3:Val1 ,但对于落后的兼容性,也把点名列入封面范围。
使用:
LineChartScene::LineChartSceneImpl::ShowLabels
无<代码>的通知 ContextMenuAction in the line. 这是因为在 类型内没有涵盖面值标签,而是在范围上加以界定,在这种情况下,范围是类别。 我知道这段话题是
你不需要大事的名称,但你正在正确轨道上:
LineChartScene::LineChartSceneImpl::ShowLabels
