有一个更好的解决方案,我刚刚在我的工作中应用了一个类似的案例。
我通过将以下配置添加到表中来做到这一点:
// make checkbox cells editable
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITABLE_RULE, IEditableRule.ALWAYS_EDITABLE, DisplayMode.EDIT, CONFIG_LABEL_CHECKBOX);
// register the checkbox editor for DisplayMode.EDIT
configRegistry.registerConfigAttribute(EditConfigAttributes.CELL_EDITOR, new CheckBoxCellEditor(), DisplayMode.EDIT, CONFIG_LABEL_CHECKBOX);
// register the checkbox painter for DisplayMode.NORMAL
configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new CheckBoxPainter(), DisplayMode.NORMAL, CONFIG_LABEL_CHECKBOX);
// register the painter for empty cells in DisplayMode.NORMAL
configRegistry.registerConfigAttribute(CellConfigAttributes.CELL_PAINTER, new BackgroundPainter(), DisplayMode.NORMAL, CONFIG_LABEL_EMPTY);
基本上,这为可编辑复选框引入了配置标签 CONFIG_LABEL_CHECKBOX,为空单元格引入了 CONFIG_LABEL_EMPTY。
现在您所要做的就是将一个附加IConfigLabelAccumulator
到您的bodyDataLayer
:
bodyDataLayer.setConfigLabelAccumulator(new IConfigLabelAccumulator()
{
public void accumulateConfigLabels(LabelStack configLabels, int columnPosition, int rowPosition)
{
if(columnPosition == CHECKBOX_COLUMN_INDEX)
{
if(someCodeToCheckIfRowIsEditable(rowPosition))
{
configLabels.add(CONFIG_LABEL_CHECKBOX);
}
else
{
configLabels.add(CONFIG_LABEL_EMPTY);
}
}
}
}
