<![CDATA[Forcing GetDDescription() refresh in ToolData plugin (EventAdd not working)]]>Hi,
I’m writing a ToolData plugin with the C++ SDK.
I see that GetDDescription() is automatically called when:
the tool is first activated (before InitTool()),the user interacts with the Attribute Manager (e.g. clicks on a choice control),and when parameters change.
That works fine.

But I also need to refresh the Attribute Manager description when my tool state changes during runtime (for example inside MouseInput(), or after some internal state update).

I tried calling : EventAdd(EVENT_FORCEREDRAW);
…but this does not cause GetDDescription() to be called again for my tool.

So my questions are:
What is the correct way to force GetDDescription() to run again for a ToolData plugin?
Is there a specific event or API call I should use to tell the Attribute Manager to rebuild the description?
Any best practices for dynamically updating tool descriptions at runtime?

Thanks!

No further testing is needed—this works very well.
I’m calling it from the ToolData::MouseInput() callback at the end, which is sufficient. The panel updates nicely after the mouse event finishes (on mouse up).

SendCoreMessage(COREMSG_CINEMA, BaseContainer(COREMSG_CINEMA_FORCE_AM_UPDATE));
GeUpdateUI();

You can close this thread.
Thanks!
V.

With that's said here are few hints (at least what I would try first).

  • Send COREMSG_CINEMA_FORCE_AM_UPDATE.
  • Call GeUpdateUI.
  • It may not be possible at all to do during a drag operation (but I will ask about it only once the two previous solutions are confirmed to not work, which I do not have the time to test right now).

Cheers,
Maxime
