Also: separated tree size calculation from draw() code,
so that one can cause the tree to recalculate immediately
after making modifications to the tree by calling Fl_Tree::calc_tree().
Numerous improvements to docs for the tree as well, enough
to create a rather large diff.
Large internal changes were needed to do this properly.
The following was added to the CHANGES file:
- Fl_Tree: various related changes:
o Added horizontal scrollbar
o Separated draw() and tree size calculation
o Added new public methods:
> resize() -- uses optimized dim calc, avoids tree recalc
> next_item() -- added parameters: direction, visibility
> extend_selection() -- added parameters, improved algorithm
> calc_dimensions() -- calc tix/y/w/h, tox/y/w/h and scrollbars
> calc_tree() -- calc tree_w/tree_h
> recalc_tree() -- schedules calc_tree()
> first_visible_item(), last_visible_item(), next_visible_item()
> first_selected_item(), last_selected_item(), next_selected_item()
o Added protected variables:
> _tix/y/w/h -- tree widget 'inner' dimension
> _tox/y/w/h -- tree widget 'outer' dimension
> _tree_w,_tree_h -- entire tree hierarchy width/height
o Deprecated:
> item_clicked() -- use callback_item() instead
> first_visible() -- use first_visible_item() instead
> last_visible() -- use last_visible_item() instead
- Fl_Tree_Item: various related changes:
o Added Fl_Tree ptr: needed for auto-recalc when item modified directly
o Added new methods tree(), recalc_tree()
o Added new ctor that accepts Fl_Tree*
o draw() parameters changed to include tree size calculations
o Deprecated:
> ctor using Fl_Tree_Prefs parameter (Fl_Tree* version better,
and must be used for 1.3.3 ABI features to work correctly)
> next_displayed() -- use next_visible() instead
> prev_displayed() -- use prev_visible() instead
- test/tree: added tests for newly added features
