Member Function Documentation

CreateCursorFromRGBABuffer()

void * FLinuxCursor::CreateCursorFromRGBABuffer ( const FColor *  Pixels, int32  Width, int32  Height, FVector2D  InHotSpot  )

overridevirtual

Creates a hardware cursor from bitmap data. Can return nullptr when not available.

Reimplemented from ICursor.

GetPosition()

FVector2D FLinuxCursor::GetPosition ( ) const

overridevirtual

The position of the cursor

Implements ICursor.

GetSize()

void FLinuxCursor::GetSize ( int32 &  Width, int32 &  Height  ) const

overridevirtual

Gets the size of the cursor

Implements ICursor.

GetType()

virtual EMouseCursor::Type FLinuxCursor::GetType ( ) const

inlineoverridevirtual

Gets the current type of the cursor

Implements ICursor.

InvalidateCaches()

void FLinuxCursor::InvalidateCaches

(

)

Invalidates whatever cached data cursor may have

IsCreateCursorFromRGBABufferSupported()

virtual bool FLinuxCursor::IsCreateCursorFromRGBABufferSupported ( ) const

inlineoverridevirtual

Is CreateCursorFromRGBABuffer() supported by this cursor?

Reimplemented from ICursor.

IsHidden()

bool FLinuxCursor::IsHidden

(

)

Lock()

void FLinuxCursor::Lock ( const RECT *const  Bounds )

overridevirtual

Locks the cursor to the passed in bounds

Parameters

Bounds

The bounds to lock the cursor to. Pass NULL to unlock.

Implements ICursor.

SetCachedPosition()

void FLinuxCursor::SetCachedPosition	(	const float	X,
		const float	Y
	)

Set the internal cached position, setting the cache to valid

SetCustomShape()

void FLinuxCursor::SetCustomShape ( SDL_HCursor  CursorHandle )

virtual

Defines a custom cursor shape for the EMouseCursor::Custom type.

Parameters

CursorHandle

A native cursor handle to show when EMouseCursor::Custom is selected.

SetPosition()

void FLinuxCursor::SetPosition ( const int32  X, const int32  Y  )

overridevirtual

Sets the position of the cursor

Implements ICursor.

SetType()

void FLinuxCursor::SetType ( const EMouseCursor::Type  InNewCursor )

overridevirtual

Sets the cursor

Implements ICursor.

SetTypeShape()

void FLinuxCursor::SetTypeShape ( EMouseCursor::Type  InCursorType, void *  CursorHandle  )

overridevirtual

Allows overriding the shape of a particular cursor.

Implements ICursor.

Show()

void FLinuxCursor::Show ( bool  bShow )

overridevirtual

Shows or hides the cursor

Parameters

bShow

true to show the mouse cursor, false to hide it

Implements ICursor.
