有我剛纔應用到類似的情況在我的工作,更好的解決方案。
我做到了通過添加下面的配置表中:
// 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,這引入了配置標記CONFIG_LABEL_CHECKBOX爲可編輯的複選框,用於CONFIG_LABEL_EMPTY一個空單元格。
現在,所有你需要做的是將IConfigLabelAccumulator
連接到您的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);
}
}
}
}
