Hi,
I am trying to add my custom layout in eclipse using VE but I am not able
to see my Custom Manager in the layout properties list.
The structure of the project is:
package: com.layout contains the following code
1) CustomLayout.java
2) CustomLayoutBeanInfo.java
package: com.layout.helper contains the following code
1) CustomLayoutEditPolicy.java
2) CustomLayoutPolicyFactory.java
Folder: overrides.com.layout
1) LayoutManager.override
2) CustomLayout.override
Is it necessary to write the PolicyFactory class and EditPolicy class to
view the CustomLayout manager class in the properties list???
Code is as follows:
LayoutManager.override
