未在渲染器中设置RowSorter [英] RowSorter not set in renderer

问题描述

我在jTable中实现了用于对列进行排序的图标. 我有一个用于查找结果的按钮，并且在启动工作程序时实现默认的排序. 像这样:

I implement icon for sorting column in my jTable. I have a button for find result and i implement a default sorting when i launch the worker. Like this :

public void refreshStripedViewTable(final List<FlightBox> boxList,
        final List<FlightBoxModel> boxesModels, final String sortBy) {
        if (boxList != null && !boxList.isEmpty()) {
            stripedViewTableModel.setContent(boxesModels);
            tableRenderer.setStripedViewModelList(boxesModels);
            final RowSorter<? extends TableModel> sorter = tableFacade
                .getTooltipsTable().getRowSorter();
            if (sorter != null) {
                List<SortKey> sortKeys = new ArrayList<SortKey>();
                javax.swing.RowSorter.SortKey sk = new SortKey(getColumnIndex(
                    sortBy, tableFacade.getTooltipsTable()),
                    SortOrder.ASCENDING);
                sortKeys.add(sk);
                sorter.setSortKeys(sortKeys);
                tableFacade.getTooltipsTable().setRowSorter(sorter);
                tableFacade.getTooltipsTable().validate();
                tableFacade.getTooltipsTable().getModelTable()
                    .fireTableDataChanged();
            }
        }
    }

当用户单击我的JTable的标题时，我为setIcon添加了一个渲染器.

i add a renderer for setIcon when user click on header on my JTable.

public Component getTableCellRendererComponent(final JTable table,
        final Object value, final boolean isSelected, final boolean hasFocus,
        final int row, final int column) {
        setIcon(null);
        super.getTableCellRendererComponent(table, value, isSelected, hasFocus,
            row, column);
        setOpaque(false);
        setForeground(Color.white);
        final RowSorter<?> sorter = table.getRowSorter();
        if (sorter != null) {
            java.util.List<? extends javax.swing.RowSorter.SortKey> sortKeys = sorter
                .getSortKeys();
            if (sortKeys.size() > 0) {
                javax.swing.RowSorter.SortKey sk = sortKeys.get(0);
                // take in account if the user moves the column
                if (column == table.convertColumnIndexToView(sk.getColumn())) {
                    Icon icon = null;
                    if (sk.getSortOrder() == SortOrder.ASCENDING) {
                        icon = iconService
                            .getRessourceIcon(MediaHmiService.TABLE_SORT_ORDER_ASCENDING);
                    } else if (sk.getSortOrder() == SortOrder.DESCENDING) {
                        icon = iconService
                            .getRessourceIcon(MediaHmiService.TABLE_SORT_ORDER_DESCENDING);
                    }
                    setIcon(icon);
                }
            }
        }
        setHorizontalTextPosition(SwingConstants.LEFT);
        return this;
    }

当我这样做时，我有一个问题: -找到结果->在默认列排序上设置了图标，确定 -单击标题上的设置"图标，确定 -重新启动搜索->看不见图标. 我的渲染器没有sortKeys，但是我在我的方法中设置了rowSorter refreshStripedViewTable().我不明白为什么...

I have a problem when i do this : - Found result --> Icon is set on default column sorting OK - Click on header for set icon OK - Relaunch search --> Not icon is visible.KO My renderer don't have sortKeys but i set rowSorter in my methode refreshStripedViewTable().I don't understand why...

感谢大家的帮助. 问候.

Thanks guys for your help. Regards.

执行此操作时出现问题:-找到结果->图标设置为 默认列排序OK-单击设置图标的标题OK-重新启动 搜索->看不见图标.我的渲染器没有sortKeys，但是 我在我的方法refreshStripedViewTable()中设置了rowSorter. 了解为什么...

图标默认添加到UIManager，然后当前JVM中的所有JTable都具有相同的图标

Icon are added as defaults to UIManager, then all JTables in current JVM has the same Icons

• ASCENDING

• DESCENDING

• UNSORTED
