flex - Setting 'property' on validator -

-

I am using calligraphy on each cell in a column on a datagrid. The source datagrid is set to the datapriver but the property is problematic. I can not just say 'text' because I use a label function to recover the property because it is nested inside the other object.

Any way to get around this? Do I need to create my own custom verifier? I hope not. Any suggestions are appreciated

Thanks! 

  & lt; Mx: numberValidator id = "security_locate_numberValidator" source = "{this.secId_dg.dataProvider}" The following ThanMinError = "One location is required." Property = "marketRule.locRule.locRuleId" minValue = "0" /> & Lt; Mx: DataGrid id = "secId_dg" editable = "correct" datataprakar = "{this.marketRuleServiceEntity.exceptionComposites}" itemEditEnd = "onSecurityPicked (event)" width = "100%" rowCount = "10" tab enabled = "false" & Gt; & Lt; Mx: column & gt; & Lt; Mx: DataGridColumn headerText = "Security ID" label function = "getSecId" editor DataAffield = "text" editable = "true" & gt; & Lt; Mx: itemEditor & gt; & Lt; Mx: component & gt; & Lt; Application: SecuritySuggestInput maxWidth = "160" minWidth = "160" tooltip = "Search on a ticker, CUSIP, or Sedol" width = "160" prompt = "search protection" /> & Lt; / Mx: Component & gt; & Lt; / Mx: itemEditor & gt; & Lt; / Mx: DataGridColumn & gt; & Lt; Mx: DataGridColumn headerText = "description" dataField = "description" width = "200" edit = "wrong" /> & Lt; mx: DataGridColumn headerText = "Detect" headerStyleName = "leftGridHeader" paddingRight = "4" textAlign = "right" labelFunction = "getLocate" editable = "true" dataField = "locRuleDesc" editorDataField = "selectedLabel" itemEditor = "com. Fidelity.primeservices.act.editor.overrides.LocatesEditor "/> & Lt; Mx: DataGridColumn headerText = "comments" width = "200" edit = "true" /> & Lt; Mx: DataGridColumn headerText = "delete" editable = "wrong" item service presenter = "com.fidelity.primeservices.act.renderer.overrides.SecuritiesDeleteIconRenderer" /> & Lt; / Mx: column & gt; & Lt; / Mx: data grid & gt;    
 
 
 The solution here  to use the proper combination of source   property  you were on the right track  
  source code for  says this.  
 
 supports this property strings to specify the dot-delimited nested properties   
 So in your case, you wanted to make your < code> source  property string a little more time, a few items that have reached the bottom of the vest to validate the property. Maybe:  
  source = "this.secId_dg.selectedItem.marketRule.locRule"   
 Then you'll just have to validate your property:  
  property = "locker id"

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.

Python's equivalent for Ruby's define_method? -

What is a Python equivalent for Ruby's define_method , which is the dynamic generation of class methods will allow? (As can be seen in Wikipedia) Functions are first-class objects in Python and assign them The properties of a class or an example can be a way of doing the same thing as a Wikipedia example: colors = {"black": "000", "red": "F00", "green": "0f0", "yellow": "ff0", "blue": "00f", "magenta": "fff", "cyan": "0ff", "white": " FFF "} Class MyStream (ARR): Pass for Name, Code in colors.iteritems (): def _in_colour ( W code = code): return '& lt; Span style = "color:% s" & gt;% s & lt; / Span & gt; ' % (Code, self) setter (histrive, "in_" + name, _in_ color)
