Hello, everyone. I don't know if this is the right place to ask, but I tried and couldn't find a gobject specific mail-list. Don't know where else to ask so here it goes. I am writing a class and would like to know if there is anyway that I can prevent the object from being created (or deleting it right after it, if the first alternative is impossible) when I find out problems in the constructor. The thing is: my class only makes sense when it is related with a file. Let's say it's called XFileBuffer (X_FILE_BUFFER) when a user asks for new object, like in g_object_new(X_TYPE_FILE_BUFFER, "file-name", "myfile.txt", NULL); I want to be able to check if "file-name" property is set to a file that can be read and read it to an internal buffer of my object, but I don't want it to be created when the file isn't available for some reason. Is it possible that I check the reasonable conditions inside my constructor and return NULL on the g_object_new() call the user made if they're not met ? If, so, what would be the best way of doing it (so that derived types, for instance, would automatically inherit such behavior). I believe what I am trying to make is *almost* like throwing an exception in a C++ constructor (although I don't know much C++)... and would like to know if GObject allows me to do anything like that. Thanks, Alexandre Moreira. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
