/**
* Enhanced Table component with support for general SwingX sorting/filtering,
* rendering, highlighting, rollover and search functionality. Table specific
* enhancements include runtime configuration options like toggle column
* visibility, column sizing, PENDING JW ...
*
* Sorting and Filtering
*
* JXTable supports sorting and filtering of rows (switched to core sorting).
*
* Additionally, it provides api to apply
* a specific sort order, to toggle the sort order of columns identified
* by view index or column identifier and to reset all sorts. F.i:
*
*
* table.setSortOrder("PERSON_ID", SortOrder.DESCENDING);
* table.toggleSortOder(4);
* table.resetSortOrder();
*
*
* Sorting sequence can be configured per column by setting the TableColumnExt's
* comparator property. Sorting can be disabled per column - setting the TableColumnExt's
* sortable or per table by {@link #setSortable(boolean)}.
* The table takes responsibility to propagate these
* properties to the current sorter, if available
*
* Note that the enhanced sorting controls are effective only if the RowSorter is
* of type SortController, which it is by default. Different from core JTable, the
* autoCreateRowSorter property is enabled by default. If on, the JXTable creates and
* uses a default row sorter as returned by the createDefaultRowSorter method.
*
*
* Typically, a JXTable is sortable by left clicking on column headers. By default, each
* subsequent click on a header reverses the order of the sort, and a sort arrow
* icon is automatically drawn on the header.
*
*
*
*
Rendering and Highlighting
*
* As all SwingX collection views, a JXTable is a HighlighterClient (PENDING JW:
* formally define and implement, like in AbstractTestHighlighter), that is it
* provides consistent api to add and remove Highlighters which can visually
* decorate the rendering component.
*
*
* An example multiple highlighting (default striping as appropriate for the
* current LookAndFeel, cell foreground on matching pattern, and shading a
* column):
*
*
*
* Highlighter simpleStriping = HighlighterFactory.createSimpleStriping();
* PatternPredicate patternPredicate = new PatternPredicate("ˆM", 1);
* ColorHighlighter magenta = new ColorHighlighter(patternPredicate, null,
* Color.MAGENTA, null, Color.MAGENTA);
* Highlighter shading = new ShadingColorHighlighter(
* new HighlightPredicate.ColumnHighlightPredicate(1));
*
* table.setHighlighters(simpleStriping,
* magenta,
* shading);
*
*
*
* To fully support, JXTable registers SwingX default table renderers instead of
* core defaults (see {@link DefaultTableRenderer}) The recommended approach for
* customizing rendered content it to intall a DefaultTableRenderer configured
* with a custom String- and/or IconValue. F.i. assuming the cell value is a
* File and should be rendered by showing its name followed and date of last
* change:
*
*
* StringValue sv = new StringValue() {
* public String getString(Object value) {
* if (!(value instanceof File)) return StringValues.TO_STRING.getString(value);
* return StringValues.FILE_NAME.getString(value) + ", "
* + StringValues.DATE_TO_STRING.getString(((File) value).lastModified());
* }};
* table.setCellRenderer(File.class, new DefaultTableRenderer(sv));
*
*
* In addition to super default per-class registration, JXTable registers a default
* renderer for URIs which opens the default application to view the related
* document as supported by Desktop. Note: this action is triggered only if
* rolloverEnabled is true (default value) and the cell is not editable.
*
*
* Note: DefaultTableCellRenderer and subclasses require a hack to play
* nicely with Highlighters because it has an internal "color memory" in
* setForeground/setBackground. The hack is applied by default which might lead
* to unexpected side-effects in custom renderers subclassing DTCR. See
* {@link #resetDefaultTableCellRendererHighlighter} for details.
*
*
* Note: by default JXTable disables the alternate row striping provided
* by Nimbus, instead it does use the color provided by Nimbus to configure the
* UIColorHighlighter. Like in any other LAF without striping support,
* client code has to explicitly turn on striping by
* setting a Highlighter like:
*
*
* table.addHighlighter(HighlighterFactory.createSimpleStriping());
*
*
* Alternatively, if client code wants to rely on the LAF provided striping
* support, it can set a property in the UIManager ("early" in the application
* lifetime to prevent JXTable to disable Nimbus handling it. In this case it is
* recommended to not any of the ui-dependent Highlighters provided by the
* HighlighterFactory.
*
*
* UIManager.put("Nimbus.keepAlternateRowColor", Boolean.TRUE);
*
*
* Rollover
*
* As all SwingX collection views, a JXTable supports per-cell rollover which is
* enabled by default. If enabled, the component fires rollover events on
* enter/exit of a cell which by default is promoted to the renderer if it
* implements RolloverRenderer, that is simulates live behaviour. The rollover
* events can be used by client code as well, f.i. to decorate the rollover row
* using a Highlighter.
*
*
* JXTable table = new JXTable();
* table.addHighlighter(new ColorHighlighter(HighlightPredicate.ROLLOVER_ROW,
* null, Color.RED);
*
*
* Search
*
* As all SwingX collection views, a JXTable is searchable. A search action is
* registered in its ActionMap under the key "find". The default behaviour is to
* ask the SearchFactory to open a search component on this component. The
* default keybinding is retrieved from the SearchFactory, typically ctrl-f (or
* cmd-f for Mac). Client code can register custom actions and/or bindings as
* appropriate.
*
*
* JXTable provides api to vend a renderer-controlled String representation of
* cell content. This allows the Searchable and Highlighters to use WYSIWYM
* (What-You-See-Is-What-You-Match), that is pattern matching against the actual
* string as seen by the user.
*
*
Column Configuration
*
* JXTable's default column model
* is of type TableColumnModelExt which allows management of hidden columns.
* Furthermore, it guarantees to delegate creation and configuration of table columns
* to its ColumnFactory. The factory is meant as the central place to
* customize column configuration.
*
*
* Columns can be hidden or shown by setting the visible property on the
* TableColumnExt using {@link TableColumnExt#setVisible(boolean)}. Columns can
* also be shown or hidden from the column control popup.
*
*
* The column control popup is triggered by an icon drawn to the far right of
* the column headers, above the table's scrollbar (when installed in a
* JScrollPane). The popup allows the user to select which columns should be
* shown or hidden, as well as to pack columns and turn on horizontal scrolling.
* To show or hide the column control, use the
* {@link #setColumnControlVisible(boolean show)}method.
*
*
* You can resize all columns, selected columns, or a single column using the
* methods like {@link #packAll()}. Packing combines several other aspects of a
* JXTable. If horizontal scrolling is enabled using
* {@link #setHorizontalScrollEnabled(boolean)}, then the scrollpane will allow
* the table to scroll right-left, and columns will be sized to their preferred
* size. To control the preferred sizing of a column, you can provide a
* prototype value for the column in the TableColumnExt using
* {@link TableColumnExt#setPrototypeValue(Object)}. The prototype is used as an
* indicator of the preferred size of the column. This can be useful if some
* data in a given column is very long, but where the resize algorithm would
* normally not pick this up.
*
*
*
*
*
* Keys/Actions registered with this component:
*
*
* - "find" - open an appropriate search widget for searching cell content.
* The default action registeres itself with the SearchFactory as search target.
*
- "print" - print the table
*
- {@link JXTable#HORIZONTALSCROLL_ACTION_COMMAND} - toggle the horizontal
* scrollbar
*
- {@link JXTable#PACKSELECTED_ACTION_COMMAND} - resize the selected column
* to fit the widest cell content
*
- {@link JXTable#PACKALL_ACTION_COMMAND} - resize all columns to fit the
* widest cell content in each column
*
*
*
*
* Key bindings.
*
*
* - "control F" - bound to actionKey "find".
*
*
*
* Client Properties.
*
*
* - {@link JXTable#MATCH_HIGHLIGHTER} - set to Boolean.TRUE to use a
* SearchHighlighter to mark a cell as matching.
