How to using displayOption method switch color on Form

首先要在 form 中的 datasource 中重载 displayoption方法。
1：控制行的颜色
public void displayOption(Common _record, FormRowDisplayOption _options)
{
    PushTbBOMConfiguration  config;
    config = _record;
    if (config.Color=='Red')
    {
        _options.textColor(WinAPI::RGB2int(255,0,0));
    }
    super(_record, _options);
}
  效果图：



2：控制列的颜色
public void displayOption(Common _record, FormRowDisplayOption _options)
{
    PushTbBOMConfiguration  config;
    config = _record;
   // PushTbBOMConfiguration_Size02 为表格中的某一个列
    PushTbBOMConfiguration_Size02.colorScheme(FormColorScheme::RGB);       
    PushTbBOMConfiguration_Size02.foregroundColor(WinAPI::RGB2int(255,0,0));       
    _options.affectedElementsByField(fieldnum(PushTbBOMConfiguration,size02));
       
    super(_record, _options);
}
  效果图：



3：控制单元格的颜色
public void displayOption(Common _record, FormRowDisplayOption _options)
{
    PushTbBOMConfiguration  config;
    config = _record;
   // PushTbBOMConfiguration_Size02 为表格中的某一个列
    if (config.Color=='Red')
    {
         _options.affectedElementsByControl(PushTbBOMConfiguration_Size02.id());
         _options.textColor(WinAPI::RGB2int(255,0,0));
    }
    super(_record, _options);
}
  效果图：
