Thank you!
If you are still in good mood please consider adding a method to equally size selected nodes (like those for alignment you added in 2.5).
size widths of selected to widest/narrowest node
size heights of selected to tallest/shortest node
Thanks again for improving such a great component in such a ...burst pace.

Also many thanks.
Will test with the background-transparency.
Time to port!

Made some test with background-transparency.
Can use it like in sgdemo and make the underlying label visible.
The question of the plugin-user goes beyond, because he want transparency through the form. Since form transparency is supported
by delphi7, I made the sgdemo work there with setting the form to transparent (not TSimpleGraph). But seems to work only when that window is the top-level window (and higher windows-versions). But a plugin window is a child of the host-app and does not work that way. Also when I use delphi7 I still have problems with the hint-shadows, which does not get reset.
So I could provide somewhat like an background-layer with a seperate object behind TSimpleGraph using its transparent-property. I will stay on delphi5 (hints) for now and will check which use can make sense.

Is it intentional behaviour or a bug that LoadFromFile/LoadFromStream does set the commandmode to cmEdit?
It should be possible to use them in 'cmViewOnly' I think.
(MergeFromFile/MergFromStream does not set anything.)

Taransparency in SimpleGrpah is achieved by drawing parent's canvas on the SimpleGraph's canvas. Therefore, form transparency is not supported.
Regarding Delphi 7, according to my experiences, WinXP Theme support in Delphi has lot of bugs.

Both behaviors are intentional. The developer can change the command mode after loading the graph (look at SGDemo).

I thought more about your question. What do you think about the following rules?
- Clear sets CommandMode to cmEdit
- LoadFromStream sets CommandMode to cmViewOnly
- MergeFromStream sets CommandMode to cmEdit

By default I would none of the commands change something on CommandMode.
Then it would be the responsibility of the developer how it is used.
Just my 2 cents!

Some developers are not responsible. JK
It causes a compatibility problem.

Only some?
Do whatever you want and what is needed.

IMHO, it's a minor issue (to be honnest, it's a non-issue). I think your trick serves those with such needs well.

What do you think about having OnObjectMouseEnter and OnObjectMouseLeave events?
