[comp.windows.x] Porting an HP widget to Motif....

luis@postgres.Berkeley.EDU (Luis Miguel) (07/14/89)

I have written a widget to be able to display and
manipulate arbitrary graphs. It works with the HP, R2
widget set.

I am interested in porting it to Motif, and need to
estimate how long it will take me, as well as how difficult
the port will be.

If you have experience dealing with both the HP widgets and 
Motif widget set, please let me know what you think.

Thanks,

/Luis

If you have written a widget, then most of your code would probably be
Xt Intrinsics or Xlib calls. If so, then there should be little or no
change to that code. I ported a widget from HP widgets to Motif with
no problems.

If your widget is a composite widget that uses specific HP widgets, then
you will have to find a similar widget in the Motif set. My feeling is
that there is a *pretty* good match between then two (add your favorite
disclaimer). 

A graph widget most likely uses a bunch of "generic" widgets (like
push buttons) and Xlib routines to draw the interconnections. I
don't see that you will have to change much except for some minor
naming convention differences.
