JTree and Icon

[pradeep selvaraj]

Hi,
My application has a tree structure representing packages and the classes and interfaces that they contain.

Each package contains classes and interfaces. I wanted to change the default leaf icon and did it with the following code

    DefaultTreeCellRenderer renderer = new DefaultTreeCellRenderer();
    renderer.setLeafIcon(customLeafIcon);
    tree.setCellRenderer(renderer);

By using the above code both the classes and the inferfaces can only have the same imageicon. Is there a way to set different imageicon depending on weather they are interfaces or classes.

Thanks

Serish

Is there a way by implmenting TreeCellRenderer? If it can be done that way please let me know how?

Hi Serish,

You just need implement the TreeCellRenderer ineterface and provide implementation for the getTreeCellRendererComponent method.

Ex::
MyRenderer implements TreeCellRenderer
{

public Component getTreeCellRendererComponent(JTree tree, Object value,
boolean selected, boolean expanded, boolean leaf, int row,boolean hasFocus)

{
If (value is Class)
{
setIcon();

}
else
{
}


}

}

setIcon(Class Icon);

}
else
{
setIcon(Interface Icon);
}


}

}

Then add this render obj to the Jtree.
