Deprecation warning
See class PanelNodeStyle for more details.Properties
Gets the color from the style.
Gets the layout of the node this renderer is currently configured for.
Remarks
Node.Layout.Gets or sets the currently configured node.
Gets or sets the currently configured style.
Methods
Prepares this instance for subsequent calls after the style and node have been initialized.
Remarks
Upon invocation the style and node properties have been populated by the getVisualCreator, getBoundsProvider, getHitTestable, or getMarqueeTestable methods.
This is an empty implementation. Subclasses might have to override this method.
This method is called by the framework to create a Visual that will be included into the IRenderContext.
Remarks
Parameters
A map of options to pass to the method.
- context - IRenderContext
- The context that describes where the visual will be used.
Returns
- ↪Visual
- The visual to include in the canvas object visual tree. This may be
null.

- the context to calculate the bounds for
Returns
Implements
Configures the style and node parameters, calls configure and returns this.

Parameters
A map of options to pass to the method.

Implements
Hit tests the node using the current style.
Remarks
Parameters
A map of options to pass to the method.
- context - IInputModeContext
- the context the hit test is performed in
- location - Point
- the coordinates in world coordinate system
Returns
- ↪boolean
- whether something has been hit
Implements
Tests the node using the current style for an intersection with the given box.
Remarks
Parameters
A map of options to pass to the method.
- context - IInputModeContext
- the current input mode context
- rectangle - Rect
- the box describing the marquee's bounds
Returns
- ↪boolean
trueif the node is considered to be captured by the marquee
Implements
Checks whether the given coordinate lies within the shape's geometric bounds.
Determines whether an element might intersect the visible region for a given context.
Remarks
true.Parameters
A map of options to pass to the method.
- context - ICanvasContext
- The context to determine the visibility for.
- rectangle - Rect
- The visible region clip.
Returns
- ↪boolean
falseif and only if it is safe not to paint the element because it would not affect the given clipping region.
Implements
Returns an instance that implements the given type or null.
Remarks
null implementations for the types, nor does it have to return the same instance any time. Also it depends on the type and context whether the instance returned stays up to date or needs to be reobtained for subsequent use.Type Parameters
- T: any
Parameters
A map of options to pass to the method.
- type - Class<T>
- The type for which an instance shall be returned.
Returns
- ↪T
- an instance that is assignable to type or
null

Implements
This method updates or replaces a previously created Visual for inclusion in the IRenderContext.
Remarks
The CanvasComponent uses this method to give implementations a chance to update an existing Visual that has previously been created by the same instance during a call to createVisual. Implementation may update the oldVisual and return that same reference, or create a new visual and return the new instance or null.
I most cases oldVisual is a visual instance that has been returned by the createVisual method of this instance. This is, however, not guaranteed. Implementations have to be aware of this.
Parameters
A map of options to pass to the method.
- context - IRenderContext
- The context that describes where the visual will be used in.
- oldVisual - Visual
- The visual instance to be updated.
Returns
- ↪Visual
oldVisual, if this instance modified the visual, or a new visual that should replace the existing one in the canvas object visual tree.
