/*
de.kupzog.ktools.kprint* Version 1.1
_______________________________________________________________________
This is the source of a print layout package for Java SWT applications.
The features in short terms:
- creating well layouted printed documents by putting image and text
boxes on a document
- printing swt tables and ktables (see de.kupzog.ktable) within this framework
- a page setup dialog (sorry, only in german)
- a print preview dialog (sorry, also only in german)
For a detailed function description refer to the api documentation that
is included in the sourcefiles. For examples how to use KPrint, see the
de.kupzog.ktools.kprint.example package.
Known problems:
_______________________________________________________________________
- Oversized images and tables will be printed over the margins
(but not over the page border)
- No bold/italic words within other words in a text box available
(only the complete box can be bold)
- The Print Preview can differ from the printed document (slightly
different page breakes). This is because the space occupied by text
changes with the font resolution. You can observe this phenomenon
also in some cases by changing the preview size.

*
* The idea of KTable is to have a flexible grid of cells to display data in it.
* The class focuses on displaying data and not on collecting the data to
* display. The latter is done by the KTableModel which has to be implemented
* for each specific case. The table asks the table model for the amount of
* columns and rows, the sizes of columns and rows and for the content of the
* cells which are currently drawn. Even if the table has a million rows, it
* won't get slower because it only requests those cells it currently draws.
* Only a bad table model can influence the drawing speed negatively.
*
* When drawing a cell, the table calls a KTableCellRenderer to do this work.
* The table model determines which cell renderer is used for which cell. A
* default renderer is available (KTableCellRenderer.defaultRenderer), but the
* creation of self-written renderers for specific purposes is assumed.
*
* KTable allows to resize columns and rows. Each column can have an individual
* size while the rows are all of the same height except the first row. Multiple
* column and row headers are possible. These "fixed" cells will not be scrolled
* out of sight. The column and row count always starts in the upper left corner
* with 0, independent of the number of column headers or row headers.
