v2.6 is the last release for 2.x update serries.

Probably there will be some fundamental changes in the next release of SimpleGraph.

Please post here whatever you wish for the next release of SimpleGraph, and of course bugs you may find in the current release.

Cheers

After compiled with 2.6 I set explicit to cmViewOnly,
but now I can still click on Nodes and edit.
This was not the case on <2.6.
Anything changed there?

Some more obeservations to this:

Mouse access is on on cmViewOnly, so I can
select, drag size and edit the nodes.
But keyboard action is disabled.

Could you please clarify what do you mean by "last object"?
Is it the one on the top of the pile or the one at the bottom?

Thanks

What do you think about merging:

It seems more compact that way.

So, you started!!

Are GraphGroups virtual objects (that is, with no other visualization apart from their member objects)? It would be nice (well, at least for me Embarassed

) to be able to visualize it. For example, have a GraphNode associated with it.

In a second thought I think it serves the group idea well, because you can use it to establish move, resize, background coloring, ect. The only requirement is to give the group object mouse priority. Objects belonging to a group should not be selectable (although modern apps - OfficeXP - allows direct selection inside the group). I am not sure though if Groups should be handled in a special way from the core lib. Have you make up your mind?

EDIT: One question that puzzles me regarding groups is the relationship with its member objects. Where to put the associations? Store the member IDs in the group OR store the groupID in each member object?

Kambiz · Posted: 31/03/06 17:14 Post subject:

Althought a Group is a TGraphObject, but it doesn't draw its client.

Each group has a Members property as type TGraphObjectList. Also, each object has a Group property as type TGraphGroup.

Each group treats as a single object, and its members does not appear in Objects property of SimpleGraph. The members are accessible only by Members property of the group.

The objects within a group are selectable but they will be treated as locked. Therefore, the group members cannot be moved or resized individually.

As well as other object types, a new group class can be derived from TGraphGroup and be registered in the control.
