Checking type for a GimpDisplayShell in 2.3.16

Hi all -

After presenting ingimp (http://www.ingimp.org) at LGM a week ago, it was suggested we port it to the 2.3.x developer branch. The port is almost complete, but I'm trying to understand a particular change between the 2.2.x and 2.3.x code trees.

In our interaction logging, we do a check to make sure a particular pointer is actually a GimpDisplayShell by using GIMP_IS_DISPLAY_SHELL(). In 2.2.x, this worked, but in 2.3.x there is a link error (undefined reference to gimp_display_shell_get_type). Our interaction logging code is linked in with app/core; where does this missing function reside so that we can use GIMP_IS_DISPLAY_SHELL?

Thanks for any help,

Michael Terry

Yay!

This is in app/display/gimpdisplayshell.h.

Hope this helps, Simon

Thanks for the quick response! The specific issue I'm encountering is that our code compiles just fine (we include app/display/gimpdisplayshell.h), but linking fails because it cannot find the gimp_display_shell_get_type function. I think the issue is that in app/display, this function exists *somewhere*, but when we link our logging code, the function cannot be found.

I'm probably missing something really simple here, but I know that in the 2.2.x branch, gimp_display_shell_get_type is explicitly defined in app/display/gimpdisplayshell.c. However, in 2.3.x, it is not explicitly defined in source code as far as I can tell. But it appears to exist somewhere because it can be found in the object files in the app/display directory. What am I missing?

Thanks,

Michael

It is defined by means of the G_DEFINE_TYPE() macro. The macro expands to pretty much the same code as you find in the 2.2 tree.

I knew it would be something simple...

The link error was due to the ingimp logging code being linked in with gimp-console, which doesn't have GUI code linked to it.

Thanks for the assistance.
