SM_CYDRAG top-level constant Null safety

int const SM_CYDRAG

The number of pixels above and below a mouse-down point that the mouse pointer can move before a drag operation begins. This allows the user to click and release the mouse button easily without unintentionally starting a drag operation. If this value is negative, it is subtracted from above the mouse-down point and added below it.


const SM_CYDRAG = 69;
