Hello All,
I solved the problem of starting a callback without associating it to a
callback by calling the callback the following way;
modifyGraph ((Widget)NULL, (Widget)shell, (XtPointer)NULL);
This may not be the correct way (?) but it is a good hack since it worked
very well.
On the other hand, Can anyone give me a hint on the following problem?
When darwing object in a Drawing Area, I use XDrawString to draw some
weight of the object next to the object. But when I click on object, I get
a (Moo-tiff) window from which I can change the object properties including
its weight.
The problem is that when using XDrawString to re-write the new weight, it
comes on top of the old weight and it becomes messy. How to remove the old
weight that I wrote using XDrawString? knowing that I know the coordinates
of the writtings.
Thanks a lot.
Best Regards,
