[Olena-patches] last-svn-commit-483-ge632121 Two new features in Qt interface.

* demo/viewer/browser_widget.cc, * demo/viewer/browser_widget.hh: Add arrows to change image and keep XML step. * demo/viewer/key_widget.cc, * demo/viewer/key_widget.hh: Change ListWidget to TreeWidget, Items can be disabled/enabled in groups. * demo/viewer/step_widget.cc, * demo/viewer/step_widget.hh: Small changes to keep the step when next/prev. picture is chosen. * demo/viewer/viewer.cc, * demo/viewer/xml_widget.cc: Layout adjustement. --- scribo/ChangeLog | 20 ++++++ scribo/demo/viewer/browser_widget.cc | 56 +++++++++++++++-- scribo/demo/viewer/browser_widget.hh | 8 ++- scribo/demo/viewer/key_widget.cc | 113 +++++++++++++++++++++++---------- scribo/demo/viewer/key_widget.hh | 12 +++- scribo/demo/viewer/step_widget.cc | 38 +++++++++--- scribo/demo/viewer/step_widget.hh | 4 +- scribo/demo/viewer/viewer.cc | 24 +++++--- scribo/demo/viewer/xml_widget.cc | 3 +- 9 files changed, 213 insertions(+), 65 deletions(-) diff --git a/scribo/ChangeLog b/scribo/ChangeLog index ded2117..0db82ec 100644 --- a/scribo/ChangeLog +++ b/scribo/ChangeLog @@ -1,5 +1,25 @@ 2010-07-16 Arthur Crepin-Leblond &lt;crepin(a)ptaouchnok.lrde.epita.fr&gt;
