Basically what is up is that a oFileList and a oDirList are children of the ScrolledWindow, and not of the FileSelectionBox. Beacuse of this when accessing the scrollbar regions, they have to be children of the ScrolledWindow not the FileSelectionBox. Since FileSelectionBox has two ScrolledWindows (and ScrolledLists) there was no way to find out if you were looking at the DirList scrollbar regions or the FileList scrollbar regions. Fix is to look to see if you are in a scrolledWindow. Then see if a FileList or a DirList is a child of the ScrolledWindow, if it is then adjust the object_type_stack and look at the rest of the children. */ if (object->id.object_type == oScrolledWindow && object_type != oFileListItem && object_type != oDirListItem && object_type != oFileList1 && object_type != oDirList1 && widget_class_code == mvsXmFileSelectionBoxWidgetClass) { tmp_object = object->first_child; /* Look down the scrolledWindow childrens list to see if you have a directory list or filelist object code */ while (tmp_object != NULL && ! in_dir_file_list) if (tmp_object->id.object_type == object_type_stack[tindx - 1]) in_dir_file_list = True; else tmp_object = tmp_object->next_sibling; /* If you have the dirlist of filelist then adjust the object_type stack.
