Seems like the Observer pattern is the best way to create this functionality On Apr 27, 5:16 pm, Kelo wrote: > I wrote a post like yours asking for a guidance or something that it > can explain how I can create > my own handlers and events, and how I can make a drag & drop using > mouse handlers but my issue disappeared. > > On 27 abr, 17:55, Micky wrote: > > > I’m building an application that is similar in layout to the Showcase > > example that is part of the GWT 1.6 install - there is central > > DeckPanel that contains a number of content widgets and only one of > > these widgets can be displayed at any one time.

Re: GWT 1.6 Custom Event Handler
I wrote a post like yours asking for a guidance or something that it can explain how I can create my own handlers and events, and how I can make a drag & drop using mouse handlers but my issue disappeared.

GWT 1.6 Custom Event Handler
I’m building an application that is similar in layout to the Showcase example that is part of the GWT 1.6 install - there is central DeckPanel that contains a number of content widgets and only one of these widgets can be displayed at any one time. However, whereas the content widget being displayed in the Showcase example is controlled by the Tree on the left of the screen, my content widgets need to cause other content widgets to display. I’d like to be able to fire an event (e.g. ChangeContentWidgetEvent) from the content widgets and then have an application level handler manage the change in the DeckPanel. Do I need to create a custom event for this? If so, can someone provide some guidance or good articles on doing so? Is there a better approach to what I’m trying to do? Thanks. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
