Struct RegionIteratorIsOwned

pub struct RegionIteratorIsOwned<const OWNED: bool>(/* private fields */);

This class is used to iterate through the rectangles in a region, typically when examining the damaged regions of a window within an OnPaint call.

• RegionIterator represents a C++ wxRegionIterator class instance which your code has ownership, RegionIteratorIsOwned<false> represents one which don’t own.
• Use RegionIterator’s new() or Buildable::builder() (if available) to create an instance of this class.
• See C++ wxRegionIterator class’s documentation for more details.

Implementations

impl<const OWNED: bool> RegionIteratorIsOwned<OWNED>

pub fn new() -> RegionIteratorIsOwned<OWNED>

Default constructor.

See C++ wxRegionIterator::wxRegionIterator()’s documentation.

pub fn new_with_region<R: RegionMethods>( region: &R, ) -> RegionIteratorIsOwned<OWNED>

Creates an iterator object given a region.

See C++ wxRegionIterator::wxRegionIterator()’s documentation.

pub fn none() -> Option<&'static Self>

Trait Implementations

impl Clone for RegionIteratorIsOwned<false>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<const OWNED: bool> Drop for RegionIteratorIsOwned<OWNED>

fn drop(&mut self)

Executes the destructor for this type.

impl<const OWNED: bool> DynamicCast for RegionIteratorIsOwned<OWNED>

fn class_info() -> ClassInfoIsOwned<false>

fn as_unowned<T>(&self) -> Option<<T as WxRustMethods>::Unowned>

where T: DynamicCast,

impl<const OWNED: bool> From<RegionIteratorIsOwned<OWNED>> for ObjectIsOwned<OWNED>

fn from(o: RegionIteratorIsOwned<OWNED>) -> Self

Converts to this type from the input type.

impl<const OWNED: bool> ObjectMethods for RegionIteratorIsOwned<OWNED>

fn get_class_info(&self) -> Option<ClassInfoIsOwned<false>>

This virtual function is redefined for every class that requires run-time type information, when using the wxDECLARE_CLASS macro (or similar).

fn get_ref_data(&self) -> Option<ObjectRefDataIsOwned<false>>

Returns the wxObject::m_refData pointer, i.e. the data referenced by this object.

fn is_kind_of<C>(&self, info: Option<&C>) -> bool

where C: ClassInfoMethods,

Determines whether this class is a subclass of (or the same class as) the given class.

fn is_same_as<O>(&self, obj: &O) -> bool

where O: ObjectMethods,

Returns true if this object has the same data pointer as obj.

fn ref_<O>(&self, clone: &O)

where O: ObjectMethods,

Makes this object refer to the data in clone.

fn set_ref_data<O>(&self, data: Option<&O>)

where O: ObjectRefDataMethods,

Sets the wxObject::m_refData pointer.

fn un_ref(&self)

Decrements the reference count in the associated data, and if it is zero, deletes the data.

fn un_share(&self)

This is the same of AllocExclusive() but this method is public.

impl<const OWNED: bool> RegionIteratorMethods for RegionIteratorIsOwned<OWNED>

fn get_h(&self) -> c_int

An alias for GetHeight().

fn get_height(&self) -> c_int

Returns the height value for the current region.

fn get_rect(&self) -> Rect

Returns the current rectangle.

fn get_w(&self) -> c_int

An alias for GetWidth().

fn get_width(&self) -> c_int

Returns the width value for the current region.

fn get_x(&self) -> c_int

Returns the x value for the current region.

fn get_y(&self) -> c_int

Returns the y value for the current region.

fn have_rects(&self) -> bool

Returns true if there are still some rectangles; otherwise returns false.

fn reset(&self)

Resets the iterator to the beginning of the rectangles.

fn reset_region<R: RegionMethods>(&self, region: &R)

Resets the iterator to the given region.
