tree and onkeyxxx events

[lipe]

Hello, good monrning.

Is there a way to implements onkeyxxx events on trees?

I tried this:


<class name="treeLink" extends="tree">
<method event="onkeypress">
Debug.write( 'onkeypress' );
</method>
</class>

// my tree


But it doesn´t work at all. It would be nice if the user could fire my other actions from the keyboard.

Thanks!

Hi,

The reason tree isn't getting the keyboard event is because its implementation has its "item" receiving those events. Try this:


<canvas debug="true">

<include href="lz/tree.lzx"/>

<class name="treeLink" extends="tree">
<method event="onkeydown" reference="item">
Debug.write( 'keydown' );
</method>
<method event="onkeyup" reference="item">
Debug.write( 'keyup' );
</method>
</class>

<treeLink text="top">
<treeLink text="one" />
<treeLink text="two" />
</treeLink>

</canvas>


I'll file a todo item to add keyboard events on the tree itself. Hope this helps!

Thanks a lot!

I had this same problem width js + xul, and the solution wasn´t even near as elegant as this :D
