J2MEPolish无法编译示例应用程序

Question

我想编译“诺基亚/系列60E3”设备的J2ME波兰示例应用程序“空白”。我得到一个编译错误。我做错了什么？

似乎访问了父对象的私有属性，因此无法编译。如果我尝试将它编译为"Generic/AnyPhone“设备，它可以正常工作。

它看起来像是SourcedLazyContainer类中的一个错误。它们指的是lastPointerPressY和lastPointerPressYOffset字段，仅当设备有指针事件时才可用。它们在Container类中定义如下：

//#ifdef polish.hasPointerEvents
/** vertical pointer position when it was pressed the last time */ 
protected int lastPointerPressY;
/** scrolloffset when this container was pressed the last time */
protected int lastPointerPressYOffset;
/** time in ms when this container was pressed the last time */
protected long lastPointerPressTime;
//#endif

由于您的目标设备没有此功能，因此未定义这些字段。在Generic/AnyPhone的情况下，此功能已定义，因此构建成功。您可以尝试将"hasPointerEvents“功能添加到您的devices.xml / custom-devices.xml文件中，或者在您的ant目标中设置polish.hasPointerEvents属性。
