Description Olivier Fourdan 2010-04-20 12:42:17 UTC

Reproducer program

Description of problem:

Consider the attached reproducer program.

If the label text is modified while the window is smaller than the actual label width, the resulting size may be computed wrong and the label text truncated.

Version-Release number of selected component (if applicable):

openmotif-2.3.1

How reproducible:

Always

Steps to Reproduce:
1. Save and compile the attached reproducer program
   $ tar xjf simple_label.tar.bz2
   $ cd simple_label
   $ make
   $ ./simple_label
2. Click on "Modify Label"
3. Reduce the width of the window
4. Click again on "Modify Label"
5. Enlarge the window
  
Actual results:

The label is truncated

Expected results:

The label is seen in its entirety

Additional info:

It seems the size set in GeometryManager() from Form.c based on the XmFormConstraint preferred_width field is not updated when the label is changed and still contains on previous label length.

Curent openmotif cvs still suffer the same problem.

Possible patch

This patch fixes the issue for the reproducer.

Also, tested not to break the fix for upstream bug 1298 [1], as tested with the reproducer in [2].

However, due to the fairly complex nature of XmForm, this patch needs more testing.
