Thanks for the example. That really puts it in context.
I simplified the code a little by overriding close and passing the button name.
I think it makes it clearer.
What do you think?...
<?xml version="1.0" encoding="UTF-8" ?>
<canvas debug="true">
<class name="okcanceldialog" extends="modaldialog">
<method name="close" args="buttonHit">
if ( this['onclose'] ) {
onclose.sendEvent( buttonHit );
}
super.close();
</method>
<reverselayout axis="y" />
<view layout="axis:x" >
<button onclick="classroot.close(this.name)" name="ok" text="OK"
isdefault="true" />
<button onclick="classroot.close(this.name)" name="cancel" text="Cancel"
/>
</view>
</class>
<method name="handleClose" args="buttonHit" event="onclose" reference="dlg">
switch ( buttonHit ) {
case 'ok': Debug.write( 'Dialog returned ok' ); break;
case 'cancel': Debug.write( 'Dialog returned cancel' ); break;
default: Debug.warn( 'Dialog returned ', result ); break;
}
</method>
<okcanceldialog name="dlg">
<text>Hello World!</text>
</okcanceldialog>
<button x="20" y="20" text="click me" onclick="canvas.dlg.open()" />
</canvas>

The overarching theme here is that code has to be broken apart in
asynchronous settings. Here's your original dialog example using events:
<?xml version="1.0" encoding="UTF-8" ?>
<canvas debug="true">
<class name="okcanceldialog" extends="modaldialog">
<attribute name="buttonHit"/>
<method name="ok">
this.buttonHit = "ok";
this.close();
</method>
<method name="cancel">
this.buttonHit = "cancel";
this.close();
</method>
<reverselayout axis="y" />
<view layout="axis:x" >
<button text="OK" isdefault="true">
<method name="ok" event="onclick">
if ( classroot['onclose'] ) {
classroot.onclose.sendEvent( 'ok' );
}
classroot.close();
</method>
</button>
<button text="Cancel">
<method name="cancel" event="onclick">
if ( classroot['onclose'] ) {
classroot.onclose.sendEvent( 'cancel' );
}
classroot.close();
</method>
</button>
</view>
</class>
<method name="handleClose" args="result" event="onclose"
reference="dlg">
switch ( result ) {
case 'ok': Debug.write( 'Dialog returned ok' ); break;
case 'cancel': Debug.write( 'Dialog returned cancel' );
break;
default: Debug.warn( 'Dialog returned ', result );
break;
}
</method>
<okcanceldialog name="dlg">
<text>Hello World!</text>
</okcanceldialog>
<button x="20" y="20" text="click me">
<method name="showDialog" event="onclick">
canvas.dlg.open();
</method>
</button>
</canvas>
