Properties
AggregateBounds
public RectangleF AggregateBounds { get; }
Gets the aggregate bounds of this object. This will include the bounds of all objects attached in some way to this object.
Implements: AggregateBounds
Bounds
public RectangleF Bounds { get; protected set; }
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 Note that the bounds are updated during calls to Layout(), so may be out-of-date or even unset when called outside of the usual process.
Implements: Bounds
Inlet
public virtual PointF Inlet { get; }
Gets the location for wire connections towards the sources of this parameter.
Implements: Inlet
IntegerPivot
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.
Outlet
public virtual PointF Outlet { get; }
Gets the location for wire connections towards the recipients of this parameter.
Implements: Outlet
Owner
public T Owner { get; }
Pivot
public PointF Pivot { get; set; }
Gets or sets the pivot point for these attributes. The pivot is the main point around which the attribute geometry is positioned during layout.
Implements: Pivot
Snappable
Gets whether these attributes can be used to align other objects on the canvas. Return false specifically when your object shape is not rectangular.
Implements: Snappable
Stack
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.
Methods
DefaultTooltipContent
Create the tooltip fields which are associated with this object by default.
Parameters:
| point (PointF) | Point for tooltip. |
| icon (out IIcon) | Icon. |
| caption (out string) | Caption text. |
| message (out string) | Message text. |
| details (out object) | Either text or an Action<Context, Rectangle> or null. |
| warnings (out bool) | Boolean flag indicating the existence of warnings. |
| errors (out bool) | Boolean flag indicating the existence of errors. |
Returns: True if a tooltip ought to be shown for this object at the given location.
Draw
#Overrides: Attributes<T>.Draw
Draw
Render the owner object of these attributes.
Intersects
Test whether a given rectangle intersects the shape of these attributes.
Parameters:
| box (RectangleF) | Intersection box. |
Returns: True if rectangle intersects these attributes.
Implements: Intersects
InvalidateDisplay
public virtual void InvalidateDisplay()
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.
Implements: InvalidateDisplay
IsCoincident
Test whether a given point is considered to be on the interior of these attributes.
Parameters:
| point (PointF) | Test point. |
Returns: True if point is on the object.
Implements: IsCoincident
IsContained
Test whether the shape of these attributes is fully contained within a given rectangle.
Parameters:
| box (RectangleF) | Containment box. |
Returns: True if rectangle contains these attributes.
Implements: IsContained
Layout
#public override void Layout(Shape shape)
Parameters:
| shape (Shape) |
Overrides: Attributes<T>.Layout
PivotMoved
#protected override void PivotMoved(PointF oldPivot, PointF newPivot)
Parameters:
| oldPivot (PointF) | |
| newPivot (PointF) |
Overrides: Attributes<T>.PivotMoved
TooltipDetails
Override this method to return custom details for a tooltip.
Parameters:
| point (PointF) | |
| state (ObjectSolutionState) |
Returns: One of the acceptable types of data for details. For example an array of LazyStrings or a Action<Context, RectangleF>.
