I am having trouble getting lzSetCanvasAttribute to work.
Two files are given below: setAttrTest.lzx and setAttrTest.html
In lzx file, the attribute attr is defined in canvas. The method onattr
prints a message in a debug window when value of attr is changed. Test
this by clicking on text "test"
In html file, a button calls a java function func() which calls an
alert box and then calls lzSetCanvasAttribute which changes the value
of the attribute. I expected to see a debug message but nothing
happens.
What am I missing? Thanks for any help!
<!--setAttrTest.lzx-->
<canvas debug="true" height="200">
<debug width="200" height="100" x="200" y="50"/>
<attribute name="attr" type="string" value="initial" />
<method event="onattr" >
Debug.write("in onattr");
</method>
<text name="test"> test method
<method event="onclick">
canvas.setAttribute("attr", "new value");
</method>
</text>
</canvas>
<!-- setAttrTest.html --->
