java - 删除过滤后 Jtable 结果错误

Question

我的 gui 中有一个 Jtable，我在其中投影一些结果!我还有 3 个 JCheckBox 用作过滤器!问题是，当我第一次检查 JCheckBox 时，结果被正确过滤，但是当我取消选中 JCheckBox 时，结果与应用的过滤器保持相同，这是我不希望的!

JCheckBox 监听器:

cEntertainment.addItemListener(new ItemListener(){
        public void itemStateChanged(ItemEvent e){
            int state = e.getStateChange();
            if (state == ItemEvent.SELECTED) {
                man.setEnabled(true);
                woman.setEnabled(true);
                child.setEnabled(true);
                newFilter(cEntertainment.getText());
            } else {
                man.setEnabled(false);
                man.setSelected(false);
                woman.setEnabled(false);
                woman.setSelected(false);
                child.setEnabled(false);
                child.setSelected(false);

            }
        }
    });

新的过滤方法:

private void newFilter(String type){
    RowFilter<DefaultTableModel,Object> rf = null;
    try{
        rf = RowFilter.regexFilter(type);
    }catch(java.util.regex.PatternSyntaxException e){
        return;
    }
    sorter.setRowFilter(rf);
}

问题似乎是当选中该复选框时，您永远不会删除添加到行排序器的过滤器。这样，无论复选框状态如何，过滤器都将正常工作。你应该做这样的事情:

cEntertainment.addItemListener(new ItemListener(){
    public void itemStateChanged(ItemEvent e){
        int state = e.getStateChange();
        if (state == ItemEvent.SELECTED) {
            ...
            newFilter(cEntertainment.getText());
        } else {
            ...
            removeFilter();
        }
    }
});

...

private void newFilter(String type) {
    RowFilter<DefaultTableModel,Object> rf = null;
    try{
        rf = RowFilter.regexFilter(type);
    }catch(java.util.regex.PatternSyntaxException e){
        return;
    }
    sorter.setRowFilter(rf);
}

private void removeFilter() {
    sorter.setRowFilter(null);
}

根据 DefaultRowSorter.setRowFilter(RowFilter filter) javadoc(备注是我的):

Sets the filter that determines which rows, if any, should be hidden from the view. The filter is applied before sorting. A value of null indicates all values from the model should be included.
