SynthToolBarLayoutManager does not honor Component.getMinimumSize()

    Details

      Description

      FULL PRODUCT VERSION :
      I can reproduce on Java SE 6 update 6 and also Java SE 7 b30.

      ADDITIONAL OS VERSION INFORMATION :
      Linux 2.6.25-2-686-bigmem #1 SMP Fri Jun 27 04:07:13 UTC 2008 i686 GNU/Linux

      A DESCRIPTION OF THE PROBLEM :
      When a component whose preferred size is larger than that of the toolbar is added to the toolbar, that component is resized to its preferred size. Instead, it should be resized in such a way that it fits into the toolbar (so long as the resulting size is larger than the component's minimum size).


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run the attached source code on GTK. Press the "jButton1" button. The combo box is resized as described above.


      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      The combo box should be resized so that the "jButton1" is still visible. Note that this is the outcome if you comment out the UIManager.setLookAndFeel() call.


      REPRODUCIBILITY :
      This bug can be reproduced always.
