今天我向大家介绍一种方法，用X++写一个方法就可以完成上述功能。
1、在窗体下写下如下两个方法：
1 1、 2 3 public void gotoMainTable(Object ctrl, boolean isParmObject=false, container refFrom=connull()) 4 { 5 TableName tableName; 6 FormName formName; 7 int tableID; 8 int fieldID; 9 int i, selectedMenu; 10 Args args; 11 FormRun formrun; 12 QueryBuildDataSource qbs; 13 FormDataSource formDataSource; 14 PopupMenu master = new PopupMenu(element.hWnd()); 15 int masterItem = master.insertItem('@SYS7706'); 16 int breakItem = master.insertBreak(); 17 int CancelItem = master.insertItem('@SYS50163'); 18 ; 19 selectedMenu = master.draw(); 20 if(refFrom!=connull()) 21 { 22 switch(selectedMenu) 23 { 24 case -1: break; 25 case masterItem: 26 formName = conpeek(refFrom, 1); 27 tableID = conpeek(refFrom, 2); 28 fieldID = conpeek(refFrom, 3); 29 tableName = tableid2name(tableID); 30 if(formName && TreeNode::findNode('\\Forms\\'+formName)) 31 { 32 args = new args(formName); 33 if(isParmObject)args.parmObject(ctrl); 34 args.parm("showALL"); 35 formrun = ClassFactory.FormRunClass(args); 36 formrun.init(); 37 formDataSource = SysFormDataSource::findDataSource(formRun, tableID); 38 qbs = formDataSource.query().dataSourceTable(tableID); 39 qbs.addRange(fieldID).value(ctrl.text()); 40 formrun.run(); 41 formrun.detach(); 42 } 43 break; 44 } 45 } 46 } 47 2、 48 public container getJournalType(HnTransType _transType) 49 { 50 container refFrom; 51 ; 52 switch(_transType) 53 { 54 case HnTransType::Purch : 55 refFrom=[formstr(PurchTable),tableNum(PurchTable), fieldNum(PurchTable, PurchId)]; 56 break; 57 case HnTransType::Sales : 58 refFrom=[formstr(SalesTable),tableNum(SalesTable), fieldNum(SalesTable, SalesId)]; 59 break; 60 case HnTransType::Prod : 61 refFrom=[formstr(ProdTable),tableNum(ProdTable), fieldNum(ProdTable, ProdId)]; 62 break; 63 default : 64 refFrom=connull(); 65 break; 66 } 67 return refFrom; 68 }
2、重载控件的 context方法。
1 public void context() 2 { 3 ; 4 element.gotoMainTable(this,false,element.getJournalType(HnTransTable.TransType)); 5 }
