Add ImageButton to Treegrid Problem

[shortpasta]

Using 3.1d-2012-10-30, I do not see an extraIcon field in the TreeNode class.

I tried this with no luck:

final String iconUrl = "/favicon.ico";
treeNode.setAttribute ("extraIcon", iconUrl);

And also this with no luck:

final String iconUrl = "/favicon.ico";
final String iconHtml = Canvas.imgHTML (iconUrl);
treeNode.setAttribute ("extraIcon", iconHtml);

How can this be done?

Also, is this limited to a single icon?

You can put an icon there via the extraIcon feature by setting TreeNode.extraIcon. In 3.1d builds there's an API treeGrid.isOverExtraIcon() to check if a mouse event is over the extra icon so you can make it interactive.

Hi..
Iam using TreeGrid. I have only one column like Name in TreeGrid. i added user icons
Using below code.
treeGrid.setNodeIcon("/images/Group_Menu.png");
treeGrid.setFolderIcon("/images/Group_Menu.png");

Before the user icons and after the "+ or -" symbols i want to add one more image button with handler.
Is there any possibility to achieve this.
Please find the below ScreenShot.
