Detecting Super Dev Mode from GWT Application

As mentioned, there is a property superdevmode

you can use.

Here's a real-world example:

1. Create a class containing a method that says we're not in SuperDevMode:

   public class SuperDevModeIndicator {
       public boolean isSuperDevMode() {
           return false;
       }
   }
   
         
   
           
           
           
         
   
       

2. Extend the previous class and override the method to say we 're in SuperDevMode:

   public class SuperDevModeIndicatorTrue extends SuperDevModeIndicator {
       @Override
       public boolean isSuperDevMode() {
           return true;
       }
   }
   
         
   
           
           
           
         
   
       

3. Use only one appropriate class depending on the property superdevmode
   
   - use lazy binding - put this in your *.gwt.xml
   
   :

   <!-- deferred binding for Super Dev Mode indicator -->
   <replace-with class="com.adam.project.client.SuperDevModeIndicatorTrue">
     <when-type-is class="com.adam.project.client.SuperDevModeIndicator"/>
     <when-property-is name="superdevmode" value="on" />
   </replace-with>
   
         
   
           
           
           
         
   
       

4. SuperDevModeIndicator
   
   class SuperDevModeIndicator
   
   using lazy binding:

   SuperDevModeIndicator superDevModeIndicator = GWT.create(SuperDevModeIndicator.class);
   
         
   
           
           
           
         
   
       

5. Use it to check if you are in SuperDevMode or not:

   superDevModeIndicator.isSuperDevMode();
   
         
   
           
           
           
         
   
       

Voila!
