Re: New to the BB application development

Thanks for the welcome irvin. I am really looking forward to have a great time around here and I hope the knowledge I get via this forums  help me on my project.

As of now mayor challenges :

 

1.  handeling multiple screen. My application has 7 and hopelly there is not need for data retention when moving from screen to screen. Can I have multiple main screen or I should implement just one and the rest full screens.

 

2. Placing bitmaps or bottuns on specifics locations of the screens. So far I am using field Managers to  handle the objects to screen .

 

Thanks in advance  for your help

 

Regards

 

Osvaldo

1. Multiple screens isn't that big an issue, but I don't think you'll be able to switch between them without dropping the previous screen. It's not so much a matter of drawing Screen B over Screen A as it is replacing Screen A with Screen B. As for data retention, use of the runtime store (session) or a persistent store (until cleared) will get you all the retention you need, and they aren't difficult to implement. This becomes a little more complex when you include an alternate entry point, but if your application is purely GUI then that's not necessary.

 

2. I don't actually have much experience with GUI, so I'm afraid I can't help you there. When it gets to that point, I'm sure there are threads posted about it somewhere in the Java Development section. If not, feel free to start a new one.

 

Hope that helps,

~Dom

Re: New to the BB application development

Any time :smileytongue:

 

On a side note, I've looked into GUI's a little more and I'm not entirely sure my intial response was completely correct. I've seen a few applications that can close screens without closing the application, meaning that another screen from the same application comes up to replace it. Try calling pushScreen whenever you need to include a separate window. This should technically create a new screen to supplant the previous screen. The behaviour of hte previous screen is not something I can verify, however.
