Variable Screen WAD 7.X

Hi All,

We have 1 issue while Migrating templates from WAD 3.X to WAD 7.X .WAD 3.X is based on ABAP stack and WAD 7.X is based on JAVA Stack.In WAD 3.X there is 1 class for variable screen . Is there any class for Variable Screen in WAD 7.X so that we can customize it ?Below is the screenshot for the reference .

Is there any way to hide the content in the red block and change the button description i.e. from OK to Execute .

Any help will be greatly appreciated.

Regards ,
