/**
|
|
16 |
* HTML table view copied from javax.swing.text.html.TableView.java.
|
|
17 |
*
|
|
18 |
* The original intention was to implement a box painter other
|
|
19 |
* than StyleSheet.BoxPainter which obviously is not complete.
|
|
20 |
*
|
|
21 |
* This could have been a simple task just overriding TableView.create
|
|
22 |
* with our own ViewFactory implementing an alternate BoxPainter.
|
|
23 |
*
|
|
24 |
* Unfortunately while create is public, TableView itself is
|
|
25 |
* not (why???). We have to copy the whole thing and just
|
|
26 |
* adapt one line to make inner class CellView a subclass of
|
|
27 |
* our own SHTMLBlockView instead of javax.swing.text.html.BlockView.
|
|
28 |
*
|
|
29 |
* To make things worse, TableView uses some methods from class CSS which
|
|
30 |
* are not public as well (again not clear why) so these had to be
|
|
31 |
* copied into this class too.
|
|
32 |
*
|
|
33 |
* All in all a totally ugly solution which hopefully can be corrected
|
|
34 |
* once Sun decided to tidy up the CSS part of Swing.
