PathMapperAttributes

Gets the aggregate bounds of this object. This will include the bounds of all objects attached in some way to this object.

Gets the total outer bounds of the attributes. The attributes are assumed not to exist beyond this limit. Note that the bounds are updated during calls to Layout(), so may be out-of-date or even unset when called outside of the usual process.

Override this property if the hosted control ought to be drawn on top of the underlying attributes.

Gets the hosting bounds as currently layed out.

Gets whether the pivot of these attributes is always rounded to integer coordinates. By default this property returns true, as the vast majority of objects ought to be laid out in integer coordinates.

Gets the minimum allowed width of the hosting region.

Gets or sets the pivot point for these attributes. The pivot is the main point around which the attribute geometry is positioned during layout.

Gets the Responses dispatcher for these attributes. Subclasses can subscribe to the hook events on the returned object to extend interaction behaviour beyond what the UserInputAttributes<T>.HostMouseDown(ResponseMouseArgs) family covers.

Gets whether these attributes can be used to align other objects on the canvas. Return false specifically when your object shape is not rectangular.

The horizontal layout stack along the apex row. Derived classes typically (re)assign this during Attributes<T>.Layout(Shape) and reference sub-regions via class-local index constants. The default Attributes<T>.PivotMoved(PointF, PointF) translates the stack along with Attributes<T>.Bounds.

Gets the bounds of the UI popup button. Empty if the button is not shown. Exposed so external consumers (such as canvas hints) can target the button without reaching into the protected layout stack.

Create the tooltip fields which are associated with this object by default.

Internal drawing method. Consider overriding this one instead of Attributes<T>.Draw(Context, Skin).

Handle a double click operation on these attributes. Since this is such a common operation it is provided by the base interface, rather than requiring an IResponseAttribues implementation.

Override to supply a cursor for a point over the hosted control, e.g. hover feedback over interactive elements the host draws. Called by the ICursorAwareAttributes implementation once the resize-grip cursors have been ruled out. Return null (the default) for the standard cursor.

Invoked when the bounds of the hosting control are changed. Override this method if you want to take action upon a resize.

Override to respond to a rotation gesture (trackpad two-finger rotate) over the host region. Default: no-op.

Test whether a given rectangle intersects the shape of these attributes.

Signals that the attribute's visual appearance has changed without affecting layout. Fires the owner's DocumentObject.OnDisplayChanged(), which propagates through the document to the canvas redraw subscription.

Marks the layout as dirty so it gets recomputed on the next draw cycle. Subclasses typically flip an internal _layoutValid flag. Most callers should also raise OnLayoutChanged on the owner to actually trigger a canvas redraw.

Test whether a given point is considered to be on the interior of these attributes.

Test whether the shape of these attributes is fully contained within a given rectangle.

Move these attributes a certain amount in X and Y.

Override this method if your attributes need to handle pivot motion. The default implementation translates Bounds and Stack by the pivot delta. Overrides should typically chain to this base implementation.

Override this method to return custom details for a tooltip.
