Problem with 2 tree views

[user6965273]

Hi,

I have 2 TreeViewWidgets in my dialog box. However when I dynamically populate 1 the other also gets populated.

Attached is the .fr file.

How do I keep upload of these 2 TreeViewWidgets  seperate

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.

Did you debugged to find the crash point ?

Did you debug your TreeViewHierarchyAdapter and TreeViewWidgetMgr ?

When you instantiate the dialog, then TreeViewHierarchyAdapter and TreeViewWidgetMgr gets called for both tree views.

or there could be problem related to duplicate IDs defined in WatermarkUIID.h. Did you tried running your plugin with InDesign debug build  ? you could get some asserts.

Hi Rahul,

The program is not crashing now. I have created 2 TreeViewWidgets. I have created 2 TreeViewHierarchyAdapter, 2 TreeViewWidgetMgr and 2 TreeNodeWidgets for each TreeViewWidgets. 

One of  the TreeView is populated on initialization from a file, this is happening.

In the other tree, a node is added on click of button, but this is not happening. PS the image below: 

The "ApplyDataToWidget" method of the TreeViewWidgetMgr associated with this tree is not getting called at all.

Kindly help.

Rahul ji,

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.

@Rahul_Rastogi,  you have a typo in your signature - should be "plugin".
