可以使用 ptHimetricLocationRaw 字段// 由于 ptHimetricLocationRaw 采用的是 pointerDeviceRect 坐标系,需要转换到屏幕坐标系// 转换方法就是先将 ptHimetricLocationRaw 的 X 坐标,压缩到 [0-1] 范围内,然后乘以 displayRect 的宽度,再加上 displayRect 的 left 值,即得到了...

Pointers to objects ofstructanduniontype may also appear as the left-hand operands of themember access through pointeroperator->. Because of thearray-to-pointerimplicit conversion, pointer to the first element of an array can be initialized with an expression of array type: ...
Whereas in C we may have something like this: typedef struct node { int value; struct node* left; struct node* right; } node; the equivalent code in Java would be: class Node { public: int value; Node left; Node right; } In the sense that pointers are necessary for the implement...
解决办法:将该结构体定义到.h文件中,然后再包含该头文件,或者直接将该结构体定义到当前.c文件中。 #include<stdio.h>#include<stdlib.h>#include<malloc.h>#ifndef __linkedList__H#define__linkedList__H//防止头文件被多次包含#defineMaxSize 100typedefintelementType;/*链表的定义*/typedefstruct{//***正...
