ValueTrackerAttributes

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 Note that the bounds are updated during calls to Layout(), so may be out-of-date or even unset when called outside of the usual process.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 the bounds of the components central box. This box contains the component icon and possibly other elements such as the display name.

Gets the icon or name box.

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 or sets the label box.

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 without subclassing the responder itself.

Gets or sets whether the potential input grips are shown.

Gets or sets whether the potential input grips are shown.

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.

Enumerate over all tentative input grips, provided they are being drawn.

Enumerate over all tentative output grips, provided they are being drawn.

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

Internal drawing method. Consider overriding this one instead of Draw.

Render the owner object of these attributes.

Draw the capsule background.

Draw the capsule overlay and foreground.

Override this method to draw capsule decorations immediately after the capsule foreground is drawn, but before the tentative grips and variable parameter zui is drawn.

Draw the component icon.

Draw the input parameters.

Draw the component label text.

Draw the component name.

Draw the output parameters.

Draw the user name above or below the component capsule.

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.

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.

Layout the outer bounds of the component capsule and assign the result to the Bounds property. This is the last sub-layout method to be called during component layout.

Central box layout code with input/output parameter overrides.

Input parameter layout with parameter override.

Perform layout on all input parameters and assign their respective attribute properties. This method will only affect inputs with attributes of type 'InputParameterAttributes'. This method must be called *after* LayoutCentralBox.

Default output layout with parameter list override.

Perform layout on all output parameters and assign their respective attribute properties. This method will only affect outputs with attributes of type 'OutputParameterAttributes'. This method must be called *after* LayoutCentralBox.

Move these attributes a certain amount in X and Y.

Adds the left-hand grips to the input parameters.

Adds the right-hand grips to the output parameters.

Override this method to return custom details for a tooltip.
