public interface LogicalStructure

SmartGWT classes implementing

LogicalStructure

allow their JavaScript state to be viewed in an Eclipse Java debugging environment, using Eclipse's logical structure facility. To use this:

• In Eclipse, open the Preferences dialog, and navigate to the "Logical Structures" page (Java->Debug->Logical Structures). Add two new entries:
  1. Qualified type name:

     com.smartgwt.client.core.LogicalStructure

     
     Description: SmartGWT LogicalStructure
     Applies to subtypes: Checked
     Structure type: Single value
     Code:

     this.initNativeObject(); return this;

  2. Qualified type name:

     com.smartgwt.client.core.NativeObject

     
     Description: SmartGWT NativeObject
     Applies to subtypes: Checked
     Structure type: Single value
     Code:

     return this.o.getLogicalStructure();

• Debug your SmartGWT application in Eclipse as you normally would.
• When viewing variables structurally (e.g., in the "Variables" or "Expressions" view, or when hovering over a variable), objects implementing LogicalStructure will have a

  nativeObject

  field, the contents of which are described below:
  • The

    scClassName

    field contains the underlying SmartClient class name for the object.
  • The documented attributes for the SmartClient class, and its superclasses, are displayed as separate fields.

  • nativeObject

    field values are always cast to Strings in JavaScript, unless the field is a class which implements

    LogicalStructure

    , or is an array thereof (e.g.

    Layout.members

    ). In that case, the value of the field is the underlying SmartGWT object, which in turn has its own

    nativeObject

    field, etc.
  • The

    logicalStructureErrors

    field is a string describing all of the runtime errors encountered when displaying other

    nativeObject

    fields.
  • A

    null

    value for a

    nativeObject

    field may indicate any of the following:
    • The underlying JavaScript attribute is undefined.
    • The underlying JavaScript attribute is defined, but set to

      null

      .
    • An error occurred while attempting to read the attribute, which would be documented in the value of

      logicalStructureErrors

      .

  For more information on the JavaScript state of SmartGWT objects, consult the SmartClient documentation.
