Trying to set TreeBranch expandedIcon in WTKX file

[Roger L. Whitcomb]

Hi,

                I'm currently using version 1.5, and I can successfully
create a tree with the following snippet of WTKX:

<TreeView wtkx:id="databasesTree"

      styles="{backgroundColor:'#E8E8E8'}"

      xmlns:wtkx="http://pivot.apache.org/wtkx";

      xmlns:content="org.apache.pivot.wtk.content"

      xmlns="org.apache.pivot.wtk">

      <nodeRenderer>

            <content:TreeViewNodeRenderer showIcon="true"/>

      </nodeRenderer>

      <treeData>

            <content:TreeBranch>

                  <content:TreeBranch wtkx:id="userdb" text="Databases"
icon="images/folder-closed-16.png">

                

                But, I'd like to set the "expandedIcon" in the WTKX file
like I can in code by doing this:

                  <content:TreeBranch wtkx:id="userdb" text="Databases"
icon="images/folder-closed-16.png"
expandedIcon="images/folder-open-16.png" >

 

                However, when I do this I get the following exception:

An error occurred while processing  element <content:TreeBranch>
starting at line number 11 in file
file:/C:/Projects/tooldev/src/director.jar!/com/ingres/director/install_
tree.wtkx:

I must be doing something wrong, but I can't see what it is....  I have
tried various other syntax for the image location (like "@images..." and
"%images..." and "../../../images..." all to no avail (I get the same
exception all the time).  So, I can't tell if it just can't find the
image, or if there is some other problem trying to set the
"expandedIcon" value.  The image I want to load does exist and is in the
same directory as the regular icon file (and is in the .jar file).

 

Thanks for any help.... J
