how to force view update when non using getter/setter?

[peterblazejewicz]

Hello,

Question is related to "Design" view in GWT editor window:

When subitem state is changed via getter/setter then component design view is refreshed,
e.g. I set "isBusy" property on subcomponent and view updates to reflect changes in desing of subcomponents (applied via code or css change)
But when non-property related state is changed (e.g. by using Event tab in property inspector) view does not update,
e.g. I change view when adding and removing click listener to subcomponent. Design view does not update on that change.
Only after such main component is attached to e.g. main view it correctly shows that state of subcomponents is changed,

someone knows how to solve that for click listeners assignment?

regards,
Peter

I'm not sure why adding or removing an event listener would have any effect on the design view. Event handlers only take effect at runtime, so they would typically not have any effect at design time.

A code example showing what you are trying to do would be useful.

hi Eric,

ok, here is how it looks like:
some items can could have different layout implemented depending if they have some action assigned to them or not (either listeners or by adding Command reference),
Good example is iPhone list interface:

There is consistent design for such items. 45px height box with arrow icon on the right.
That icon only appears on those items in list which have command/action assigned (usually it moves screen to another one with other list),
So i'm implementing the same. As you say there is no problem at runtime because either using "addStyleDependantName" or other way of changin UI simply works. As I posted it also works if I put container of such items into another design view (e.g. into final target class that will be working as logical screen unit) - in that view internal state of items in nexted objects is already updated on design screen.
I know that should be possible somehow because you're already applying such information when item has event assigned in current design view: it design properties Editor "event" circle, green-ish icon is put over item icon in widget tree

Peter

I think we need to see the source for this component in order to understand why its look would change at design time due to adding an event handler. That is very unusual behavior and not something we have ever seen in any other widget for GWT, Swing or SWT. Event handlers only trigger at runtime, so they have no opportunity to affect a widget at design time. Typically, you would use some other attribute to affect the actual look of the widget.
