Implementations§
source§impl MouseEvent
impl MouseEvent
sourcepub fn new(
typ: MouseEvent_Type,
button: MouseEvent_MouseButton,
pointer: Point,
modifiers: i32,
) -> Result<MouseEvent>
pub fn new( typ: MouseEvent_Type, button: MouseEvent_MouseButton, pointer: Point, modifiers: i32, ) -> Result<MouseEvent>
Constructs a MouseEvent.
§Parameters
- type: Type of the event. This can be MouseMove, MouseButtonPress, MouseButtonRelease, MouseScrollDown, MouseScrollUp, MouseDblClick.
- button: Mouse button. This can be NoButton, LeftButton, MiddleButton, RightButton, VScroll.
- pointer: Position of the event.
- modifiers: Signals if alt, ctrl or shift are pressed or their combination.

unsafe fn modify_inplace<Res>( &mut self, f: impl FnOnce(&Mat, &mut Mat) -> Res, ) -> Res
Helper function to call OpenCV functions that allow in-place modification of a
Mat
or another similar object. By passing
a mutable reference to the Mat
to this function your closure will get called with the read reference and a write references
to the same Mat
. This is unsafe in a general case as it leads to having non-exclusive mutable access to the internal data,
but it can be useful for some performance sensitive operations. One example of an OpenCV function that allows such in-place
modification is imgproc::threshold
. Read more
