@ -5,6 +5,11 @@ HIGHLIGHTS:
Currently there are two modes supoported:
- Layout groups to predefined bounds, when you can specify rectangular bounds in which vertices are layed (Bounds must be supported by algorithm used to layout vertices group)
- Generate bounds from groups, when each group is layouted using its algorithm and bounds are automatically calculated to fit all vertices in the group and then group bounds overlaps can be removed.
* Added two new label controls AttachedEdgeLabelControl and AttachedVertexLabelControl which acts like separate entities in GraphArea visual tree and have weak references to graphx controls. Default EdgeLableControl and VertexLabelControl are designed to act as the part of their parent classes and this approach impacts their customization possibilities when these parent classes are limited in size. So with the new labels you can mitigate following restrictions:
- No more label cuts when vertex is strictly limited in width or height
- No more jerky edge endpoints when edge label is too large
- No more labels behind edges or vertices. You can control how to inject them.
To use new labels you have to add them using to GraphArea::AddCustomChildControl() method and assign either VertexControl or EdgeControl for them using label::Attach() method.
DETAILED CHANGELOG:
+ Added GroupId property to IGraphXVertex interface
@ -12,10 +17,16 @@ DETAILED CHANGELOG:
+ Added two methods to EdgeControl: GetEdgePointerForSource() and GetEdgePointerForTarget() which allows to get to edge pointer objects manualy
+ Added VertexShape.Ellipse math shape
+ Added support for reversing the geometry. This is required for animating shapes along a path where the direction needs to be reversed without using the Storyboard.AutoReverse property (thanks to bleibold)
+ Added two new attached label classes for Edge and Vertex controls.
+ Added EdgeControl::LabelMouseDown event
+ Added separate ID counter for edges while autoresolving missing id
+ Added EdgeControl.UpdateLabel() method to be able to update attached edge label manually (tech means to overcome some template quizes)
+ Fixed an exception in ZoomControl caused by Ctrl + Alt + DblClick combination (thanks to persalmi)
+ Fixed NaN result for FR algorithms calc (thanks to bleibold)
+ Fixed edge bundling in the case when empty Control points are present that would sometimes cause exceptions.(thanks to bleibold)
+ Fixed bindings to DefaultEdgePointer::Visibility property
+ Fixed numerous event issues with graphX controls where events wasn't passed down the hierarchy tree
+ Improved styles flexibility by working with dependency values instead of straight assignment in some places
+ Improved overall graph cleaning in different areas allowing to easily clean graph data and fix potentional memory leaks
+ Improved random layout algorithm randomness by seeding new Guid hash whcih fixes some odd behaviour in rare cases
+ Implemented edge cut logic for EdgePointer placed at edge 'source' to gain better visual quality like its 'target' counterpart
@ -25,6 +36,7 @@ DETAILED CHANGELOG:
BREAKING CHANGES:
* IExternalLayoutAlgorithm interface now demands TEdge generic specification and have one new method ResetGraph().
* All built-in algorithms now use IMutableVertexAndEdgeSet<TVertex, TEdge> for TGraph generic specification to be able to modify Graph data on demand.
* Made Vertex and Edge ID Int64 be default. Was Int32.
