TreeViewerAttributes

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 Note that the bounds are updated during calls to Layout(), so may be out-of-date or even unset when called outside of the usual process.

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 maximum allowed size for these attributes.

Gets the minimum allowed size for these attributes.

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 thickness of the band along each side of the bounds within which a drag resizes rather than moves. Override when the object draws its own grips and the bands should line up with them; sides which cannot resize at all are zeroed on top of this, so an override only describes the bands it wants.

Gets the Responses dispatcher for these attributes. Subclasses can subscribe to the hook events on the returned object to extend interaction behaviour without subclassing the responder itself.

Gets or sets the current size of these attributes. Note that setting the value doesn't cause any automatic updates.

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.

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.

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.

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.
