Hi Klaas,
My IDE marked them as errors. I didn't notice that they were only
warnings. I got the first problem fixed. BUT I'm having a lot of
difficulty getting events connected properly in wxArt2d. I was hoping
you could steer me in the right direction. Here's what I have (and need):
I have a wxDialog which has a a2dCanvas in it. I want the user to be
able to draw and edit rectangles on the canvas, but I need to capture
data about the rectangles. The only things I need are:
- I need to know when a new rectangle is created, and need to get a
pointer to the rectangle.
- I need to know when an existing rectangle is edited (moved or resized
only), and be able to access the new dimensions of the rectangle.
I've tried connecting wxEVT_CANVASOBJECT_RESIZE_EVENTs to the rectangle
and giving the rectangle an event handler function, I've tried the same
giving my wxDialog class the event handler function. I've tried
connecting many different types of events to the a2dstToolContr, I've
tried deriving my own rectangle class and connecting events, I've tried
deriving my own tool control from a2dstToolContr and connecting events,
I've tried getting events from the a2dDrawRectangleTool, and I can't get
anything to work.
How do I capture these events?
I appreciate how responsive you are, thanks!
- Mike

Hi Mike,
All/Mostly warnings I would say, it does compile I see.
Only when linking there is a problem.
Did you set the verbose flag in cmake?
I don't see any libraries linked.
What real errors do you see ?
Regards,
Klaas
PS I do not test mingw, but on Linux it compiles oke.

Hello,
We have a project that we're trying to upgrade from wxWidgets 2.8.11
to wxWidgets 3.0, and we are simultaneously upgrading to wxArt2d 963.
We were able to compile the wxArt2d library against wxWidgets,
however, the project will not compile.
The project was able to compile with no errors before the upgrades.
We are seeing some weird errors in wxArt2d modules, so I decided to
attempt to compile the wxArt2d sample project samples/canvas/simple.
Here is a sample of some of the errors:

What is causing these errors? I've included the entire build log at
the end of this message.
Thanks,
