Problem setting different icon for node type

[blevinson]

Hello, I am using SmartGWTEE 2.2 to build a user management component. I am customizing the SmartGWTEE showcase example. I need help getting a different icon image to indicate that a user is of a certain role. For example, I would like it to default to person.png, although if it's a manager, have it change to manager.png. Can someone assist me?

Here is the relevant code so far:
EntryPoint:

 treeGrid.setDataSource(DataSource.get("employees"));
        treeGrid.setNodeIcon("icons/16/person.png");
        treeGrid.setFolderIcon("icons/16/person.png");
        treeGrid.setCanReorderRecords(true);
        treeGrid.setCanDragRecordsOut(true);
        treeGrid.setCanAcceptDroppedRecords(true);
        treeGrid.setAutoFetchData(true);
        treeGrid.setShowOpenIcons(false);
        treeGrid.setDropIconSuffix("into");
        treeGrid.setClosedIconSuffix("");

employees.ds.xml:

<field name="partyId" title="Party ID" type="text"  primaryKey="true"  required="true"/>
<field name="managerPartyId" title="Manager" type="text"  required="true" foreignKey="partyId"  rootValue="MY_INC" detail="true"/>
<field name="roleTypeIdTo" title="roleTypeIdTo"  hidden="false" type="text" length="128"/>

Sample Data Output (expressed in XML)

<List>
	<employee>
		<partyId>TRONIX</partyId>
		<managerPartyId>MY_INC</managerPartyId>
		<roleTypeIdTo>DEPARTMENT</roleTypeIdTo>
	</employee>
	<employee>
		<partyId>JohnSmith</partyId>
		<managerPartyId>MY_INC</managerPartyId>
		<roleTypeIdTo>EMPLOYEE</roleTypeIdTo>
	</employee>
	<employee>
		<partyId>JaneDoe</partyId>
		<managerPartyId>MY_INC</managerPartyId>
		<roleTypeIdTo>MANAGER</roleTypeIdTo>
	</employee>
</List>

You can use an override of TreeGrid.getIcon():

Thanks for getting back to me. Could you please be more specific. Could you please give me some example code of how I would accomplish this.

Please note that I am using SmartGWTEE/DMI and am using an object on the session. Here is the full employees.ds.xml:

<DataSource
    ID="employees"
    serverType="generic"
>
    <fields>
     <field name="partyId"      title="Party ID"     type="text"  primaryKey="true"  required="true"/>
        <field name="managerPartyId"       title="Manager"         type="text"  required="true" 
               foreignKey="partyId"  rootValue="MY_INC" detail="true"/>
        <field name="firstName" title="First Name"    hidden="true"  type="text"     length="128"/>
<field name="lastName"            title="Last Name" hidden="true"    type="text"     length="128"/>
<field name="suffix" title="Suffix"    hidden="true"        type="text"     length="128"/>
<field name="fullName" title="Name"    type="text"     length="128"/>

<field name="roleTypeIdTo" title="roleTypeIdTo"    hidden="false"        type="text"     length="128"/>

 <field name="reviewerPartyId" title="reviewerPartyId"    hidden="true"        type="text"     length="128"/>
  <field name="managerName" title="managerName"    hidden="true"        type="text"     length="128"/>
   <field name="reviewerName" title="reviewerName"    hidden="true"        type="text"     length="128"/>
    <field name="reviewer" title="reviewer"    hidden="true"        type="text"     length="128"/>
        <field name="email"           title="Email"           type="text"     length="128"/>
        <field name="department"         title="Department"        type="text"     length="128"/>
         <field name="subdept" title="Sub-Department"    hidden="true"        type="text"     length="128"/>
    </fields>
    <serverObject lookupStyle="attribute" attributeScope="session" attributeName="EmployeesDMI" className="EmployeesDMI"/>
    
</DataSource>

You'd add an override like this to your TreeGrid instance:

public String getIcon (Record node, boolean defaultState) {
   if ("MANAGER".equals(node.getAttribute("roleTypeIdTo"))) {
       return "manager.png";
   }
    return "employee.png";
}

Okay, I think this gets me close although I have a couple questions.

1) Would I put this code in my EntryPoint or do I make a new class?
2) In your sample code, it has record.getAttribute("roleTypeIdTo"), this gives me an error regarding the "record" definition.

You'd add an override like this to your TreeGrid instance:

public String getIcon (Record node, boolean defaultState) {
   if ("MANAGER".equals(record.getAttribute("roleTypeIdTo"))) {
       return "manager.png";
   }
    return "employee.png";
}

Like any method override in Java, you need to create a subclass.

Yes, the variable should have been "node" not "record".

I got it going, thank you very much for your help!
