| 34 | +/** | |
| 35 | + * An implementation of <code>Printable</code> for printing | |
| 36 | + * <code>JTable</code>s. | |
| 37 | + * <p> | |
| 38 | + * This implementation spreads table rows naturally in sequence | |
| 39 | + * across multiple pages, fitting as many rows as possible per page. | |
| 40 | + * The distribution of columns, on the other hand, is controlled by a | |
| 41 | + * printing mode parameter passed to the constructor. When | |
| 42 | + * <code>JTable.PrintMode.NORMAL</code> is used, the implementation | |
| 43 | + * handles columns in a similar manner to how it handles rows, spreading them | |
| 44 | + * across multiple pages (in an order consistent with the table's | |
| 45 | + * <code>ComponentOrientation</code>). | |
| 46 | + * When <code>JTable.PrintMode.FIT_WIDTH</code> is given, the implementation | |
| 47 | + * scales the output smaller if necessary, to ensure that all columns fit on | |
| 48 | + * the page. (Note that width and height are scaled equally, ensuring that the | |
| 49 | + * aspect ratio remains the same). | |
| 50 | + * <p> | |
| 51 | + * The portion of table printed on each page is headed by the | |
| 52 | + * appropriate section of the table's <code>JTableHeader</code>. | |
| 53 | + * <p> | |
| 54 | + * Header and footer text can be added to the output by providing | |
| 55 | + * <code>MessageFormat</code> instances to the constructor. The | |
| 56 | + * printing code requests Strings from the formats by calling | |
| 57 | + * their <code>format</code> method with a single parameter: | |
| 58 | + * an <code>Object</code> array containing a single element of type | |
| 59 | + * <code>Integer</code>, representing the current page number. | |
| 60 | + * <p> | |
| 61 | + * There are certain circumstances where this <code>Printable</code> | |
| 62 | + * cannot fit items appropriately, resulting in clipped output. | |
| 63 | + * These are: | |
| 64 | + * <ul> | |
| 65 | + * <li>In any mode, when the header or footer text is too wide to | |
| 66 | + * fit completely in the printable area. The implementation | |
| 67 | + * prints as much of the text as possible starting from the beginning, | |
| 68 | + * as determined by the table's <code>ComponentOrientation</code>. | |
| 69 | + * <li>In any mode, when a row is too tall to fit in the | |
| 70 | + * printable area. The upper most portion of the row | |
| 71 | + * is printed and no lower border is shown. | |
| 72 | + * <li>In <code>JTable.PrintMode.NORMAL</code> when a column | |
| 73 | + * is too wide to fit in the printable area. The center of the | |
| 74 | + * column is printed and no left and right borders are shown. | |
| 75 | + * </ul> | |
| 76 | + * <p> | |
| 77 | + * It is entirely valid for a developer to wrap this <code>Printable</code> | |
| 78 | + * inside another in order to create complex reports and documents. They may | |
| 79 | + * even request that different pages be rendered into different sized | |
| 80 | + * printable areas. The implementation was designed to handle this by | |
| 81 | + * performing most of its calculations on the fly. However, providing different | |
| 82 | + * sizes works best when <code>JTable.PrintMode.FIT_WIDTH</code> is used, or | |
| 83 | + * when only the printable width is changed between pages. This is because when | |
| 84 | + * it is printing a set of rows in <code>JTable.PrintMode.NORMAL</code> and the | |
| 85 | + * implementation determines a need to distribute columns across pages, | |
| 86 | + * it assumes that all of those rows will fit on each subsequent page needed | |
| 87 | + * to fit the columns. | |
| 88 | + * <p> | |
| 89 | + * It is the responsibility of the developer to ensure that the table is not | |
| 90 | + * modified in any way after this <code>Printable</code> is created (invalid | |
| 91 | + * modifications include changes in: size, renderers, or underlying data). | |
| 92 | + * The behavior of this <code>Printable</code> is undefined if the table is | |
| 93 | + * changed at any time after creation. | |
