Detailed Description
This class handles Kate's caching of layouting information (in KateLineLayout and KateTextLayout).
This information is used primarily by both the view and the renderer.
We outsource the hardcore layouting logic to the renderer, but other than that, this class handles all manipulation of the layout objects.
This is separate from the renderer 1) for clarity 2) so you can have separate caches for separate views of the same document, even for view and printer (if the renderer is made to support rendering onto different targets).

Member Function Documentation
| KateLineLayoutPtr KateLayoutCache::line | ( | int | realLine, |
| int | virtualLine = -1 |
||
| ) |
Returns the KateLineLayout for the specified line.
If one does not exist, it will be created and laid out. Layouts which are not directly part of the view will be kept until the cache is full or until they are invalidated by other means (eg. the text changes).
- Parameters
-
realLine real line number of the layout to retrieve. virtualLine virtual line number. only needed if you think it may have changed (ie. basically internal to KateLayoutCache)
Definition at line 283 of file katelayoutcache.cpp.
| KateLineLayoutPtr KateLayoutCache::line | ( | const KTextEditor::Cursor & | realCursor | ) |
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Definition at line 336 of file katelayoutcache.cpp.
| KateTextLayout KateLayoutCache::textLayout | ( | const KTextEditor::Cursor & | realCursor | ) |
Returns the layout describing the text line which is occupied by realCursor.
Definition at line 341 of file katelayoutcache.cpp.
| KateTextLayout KateLayoutCache::textLayout | ( | uint | realLine, |
| int | viewLine | ||
| ) |
Returns the layout of the specified realLine + viewLine.
if viewLine is -1, return the last.
Definition at line 346 of file katelayoutcache.cpp.
| KateTextLayout & KateLayoutCache::viewLine | ( | int | viewLine | ) |
Returns the layout of the corresponding line in the view.
Definition at line 351 of file katelayoutcache.cpp.
| int KateLayoutCache::viewLine | ( | const KTextEditor::Cursor & | realCursor | ) |
This returns the view line upon which realCursor is situated.
The view line is the number of lines in the view from the first line The supplied cursor should be in real lines.
