Note: If you just want to pass a pointer to an object to a foreign function call, you should use byref(obj) which is much faster. 简单翻译一下就是:POINTER()创建并返回一个新的指针类型,pointer()创建一个新的指针实例,一个是针对类型,一个是针对实际对象,这里还提到了byref(),上面有说到,如果...

Use this function to retrieve a pointer to the parent tabbed window. Sometimes it is not enough to call GetParent, because a pane may be inside a docking wrapper ( CDockablePaneAdapter Class) or inside a pane adapter ( CDockablePaneAdapter Class). By using GetParentTabWnd you will be able ...

I create a Objective-C function that returns the appropriate class: Class<Object> classObject(void) { if (myFlag) { return [sObject class]; } else { return [oObject class]; } } Swift deals with this really well - I can create an initialized object using: let object = classObject()...
