自定义按钮，如何设置图标？

一：这是活动单据增加“批示”按钮的例子，可以参考
void m_BillInterface_OnBarInitialize(object sender, EventArgs e)
{
//活动批示
m_BillInterface.RemoveBarItem("mnuEditComment");
m_BillInterface.AddBarItem("mnuEditComment", "批示", "批示", "批示", null, "imgtbtn_log", null, "", true, true, true, false, true);
m_BillInterface.AddBarItemLink("ToolBar", "mnuEditComment", "mnuToolBarSepaPreview", true);
m_BillInterface.AddBarItemLink("mnuEdit", "mnuEditComment", "mnuEditCancel", true);
}

imgtbtn_log是图片资源，放在C:\Program Files\Kingdee\K3ERP\KDHR\SITEFILE\WEBUI\IMAGES\ToolBar\chs这个路径下，图片名tbtn_log，在插件中引用需要在前面加img
二：下面则是将现有的删除按钮命名为“移除”，并替换图标的
m_ListInterface.SetBarItemProperty("mnuEditDelete", Enu_BarItemProperty.Caption, "移除");
m_ListInterface.SetBarItemProperty("mnuEditDelete", Enu_BarItemProperty.Description, "移除");
m_ListInterface.SetBarItemProperty("mnuEditDelete", Enu_BarItemProperty.ImageKey, "imgtbtn_allfinitialize");
