    You are using the same Implementation ID and same CPP files for TreeVierwWidgetMgr and TreeViewHierarchyAdapter.

     

    When treeview is displayed it calls functions such as GetNumOfItems, GetNthItem etc. Becuase your cpp files are common, both tree view widgets uses the same business logic and displays the same content.

     

    Solution -

    Create separate implementationID and corresponding cpp files.

    Hello Rahul,

     

    I did try with seperate implemention ID and corresponding cpp files, but it crashes on dialog creation: line 174 in WatermarkUIActionComponent.cpp.

     

    You can get the source code from this link .

     

    The sub directory "Data Text Files" contains all the text files used in the plugin.

    The sub directory "Build Related Files" contains *.vcxproj* files.

     

    This is my first plugin. Trying to build my plugin by modifying the watermarkui plugin in SDKSamples. Kindly help.

    Hi Ziauddin,

     

    On click of button do the following -

     

    1. Call ITreeViewMgr->ChangeRoot() and ITreeViewMgr->RefreshSubTree.

    This will make sure that tree will be initialized again and ITreeViewAdapter and ITreeViewWidgetMgrWidgetMgr functions gets called again to fill the tree view.

     

    2. After above functions are called you can debug and validate whether - ITreeViewHierarchyAdapter->GetNumListItems is getting called or not.

     

    Also, implement ITreeViewHierarchyAdapter->GetNthListItem.

     

    If ITreeViewHierarchyAdapter->GetNumListItems is returning 0 then "ApplyDataToWidget" will never gets called because you return 0 number of items in "GetNumListItems'.

     

    Hope this helps.
