I'm having trouble hiding objects within a resourcce. I've tried changing the object's flag (i.e. obj.ob_flag = HIDETREE) and redrawing the tree - but no go. I can do anything else (make selectable, crossed, deselected, etc...) but I can't hide the object. I'm sure this is possible (the Resource Construction Kit allows it). Also, when I decompile a resource containing both hidden and unhidden objects (using the resdecomp) the listing states those objects that were hidden with the entry "OPTION: hidden". And when I execute the resource, sure enough, the objects with "OPTION: hidden" are hidden and those without are displayed. Any suggestions? Thanks, Sean Sterling Foiles / Univ.

No. You hide the object by setting the HIDETREE flag bit on the object you wish to hide, but you must then redraw the parent of the object being hidden. This actually makes sense, once you think about it. When an object is hidden, it is ignored by the object drawing routines. If you draw an object, then set the HIDETREE bit, and redraw it, it gets ignored. This means that it still appears to be on the display, since there was no visible change. If you redraw the parent of the object, it replaces the old image. Then, since the hidden object gets ignored, the portion of the parent which is "behind" the hidden object continues to be visible on the display. -- * George R.
