Methods

CreateControl() 

public virtual void CreateControl()

CreateLabel() 

public SkiaLabel CreateLabel()

Returns

SkiaLabel

DisposePlatform() 

public void DisposePlatform()

GetCursorPosition(float, float)

Input in pixels

protected int GetCursorPosition(float x, float y)

Parameters

x float
y float

Returns

int

MoveCursorTo(double, double)

Translate cursor from the left top corner, params in pts.

protected virtual void MoveCursorTo(double x, double y)

Parameters

x double
y double

MoveInternalCursor()

Sets native contol cursor position to CursorPosition and calls UpdateCursorVisibility

protected void MoveInternalCursor()

OnControlCreated() 

protected virtual void OnControlCreated()

OnCreatingLabel(SkiaLabel) 

protected virtual SkiaLabel OnCreatingLabel(SkiaLabel label)

Parameters

label SkiaLabel

Returns

SkiaLabel

OnDisposing()

Base performs some cleanup actions with Superview

public override void OnDisposing()

OnFocusChanged(bool)

This will be called only for views registered at Superview.FocusedChild. The view must return true of false to indicate if it accepts focus.

public override bool OnFocusChanged(bool focus)

Parameters

focus bool

Returns

bool

OnLayoutChanged()

DrawingRect size changed

protected override void OnLayoutChanged()

OnMeasuring(float, float, float)

If you call this while measurement is in process (IsMeasuring==True) will return last measured value.

public override ScaledSize OnMeasuring(float widthConstraint, float heightConstraint, float scale)

Parameters

widthConstraint float
heightConstraint float
scale float

Returns

ScaledSize

OnWillDisposeWithChildren()

The OnDisposing might come with a delay to avoid disposing resources at use. This method will be called without delay when Dispose() is invoked. Disposed will set to True and for Views their OnWillDisposeWithChildren will be called.

public override void OnWillDisposeWithChildren()

ProcessGestures(SkiaGesturesParameters, GestureEventProcessingInfo) 

public override ISkiaGestureListener ProcessGestures(SkiaGesturesParameters args, GestureEventProcessingInfo apply)

Parameters

args SkiaGesturesParameters
apply GestureEventProcessingInfo

Returns

ISkiaGestureListener

SetCursorPositionNative(int, int) 

public void SetCursorPositionNative(int position, int stop = -1)

Parameters

position int
stop int

SetCursorPositionWithDelay(int, int)

We have to sync with a delay after text was changed otherwise the cursor position is not updated yet. Using restarting timer, every time this is called the timer is reset if callback wasn't executed yet.

protected void SetCursorPositionWithDelay(int ms, int position)

Parameters

ms int
position int

SetFocus(bool) 

public void SetFocus(bool focus)

Parameters

focus bool

SetFocusInternal(bool) 

protected void SetFocusInternal(bool value)

Parameters

value bool
