| 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. | ||
