Hi, I get this error when trying to build graphic-forms-uitoolkit with SBCL 1.0.2 on Windows XP. d.

I'll make some wrappers to do it. On another subject, the list of controls you make available in graphic-forms is still limited. Is that because you haven't needed more, yet, or are there technical impediments? I would like to use most of the controls in MFC - http://msdn2.microsoft.com/en-us/library/47xcww9x(VS.80).aspx -, do you have some quick recipe ready for this? It'd be great to share user's widgets!

[graphic-forms-devel] Dialogs return values
by Edgar Gonçalves 25 Mar '07

Hi! I've just started playing with graphic-forms, and I wanted to build some macros to generate message-boxes (which I did based on your demo about-dialog), and some input-prompts, like Yes/No questions, or a simple OK/Cancel. But I'm not figuring how I can set a return value for such functions (they seem to return the value 4 once (gfw:show dlg t) is called). Right now I managed a dirty hack by placing a global variable and making the dialog change it. but this is not as functional as I would want... Any suggestions? Thanks, -- Edgar Gonçalves Instituto Superior Técnico, INESC-ID - Software Engineering Group, Portugal
