13. 属性和代码如下：
1. wroot_dw_query属性：
X = 9 Y = 1132 Width = 2912 Height = 712
Visible = true Enabled = true TitleBar = true Title = "定位查询"
ControlMenu = true Border = true WindowType = response! WindowState = normal!
BackColor = 79741120 |
2. 窗口实例变量：
Boolean ib_changed
Long MaxEditRow = 1
String sWhere, oldsql, orisql, is_title, is_section = 'WhereClause'
DataWindow dw_result,dw_detail
pfc_n_cst_string inv_string
string sSyntax |
注释：a.pfc_n_cst_string 为PFC用户对象。
3. 窗口事件代码：
3.1 close 事件：
功能：将用户本次所输入的查询条件记录到文件sIniFile的WhereClause1...n小节中去以备下次启动时置初始查询条件。
3.2 open 事件：
功能：设置初始值，具体请看代码中的注释。
