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: ...
A mutable pointer to the elements of an array is implicitly created when you pass the array using inout syntax. This example uses implicit bridging to pass a pointer to the elements ofnumberswhen callingprintInt(atAddress:). varnumbers=[5,10,15,20]printInt(atAddress:&numbers)// Prints "5...
In my System code I create a struct and fill it with the inputs of the System. Now I want to pass a pointer to that struct to my extern send function (with some other arguments). Here is the Code: 테마복사 toFluco_struct = struct('velo...
