[Iup-users] IupLoadImage causing Seg Fault for me

[Antonio Scuri]

  IupLoadImage returns an image, that is a resource not a control. 

  You must add a control like label or button, then associate the image to
the control. Can use for instance:

IupSetAttributeHandle(label, "IMAGE", IupLoadImage ("support/logo.png"));

  This will run even if IupLoadImage fails.

Best,
scuri
