[Laszlo-user] handler "ondblclick" does not work in <grid>

[Alejandro Alanis]

Hi,

untested with your code, and made for an earlier version but should
still work:

  <class name="dblclickablegridrow" extends="basegridrow">
  	<!--
  		extends basegridrow with the ability to fire   ondblclick-Event to
the grid :)
  	-->
  	<handler name="ondblclick">
  		this.parent.parent.parent.ondblclick.sendEvent(this);
  	</handler>
  </class>

in your grid, overwrite the _rowclass-attribute like this:
  <grid _rowclass="dblclickablegridrow" ...



HTH, Alex Alanis
