Is it possible to create screens at runtime?

[thiago borges martins]

Good afternoon, colleagues,

I'm on a project where I need to create screens using smart-gwt, but the creation of the screens will be in runtime system.

This is possible using Smart-gwt?

I thank everyone's attention.

Unless I don't understand your question, this is THE main GWT feature, thus smart-gwt too !

I will explain better.

My application will have a screen that has the functionality to create a new screen with fields, business rules (insert, update and delete) and searches in the database. It's as if I've been developing the screen with fields, combobox, checkbox and grid's that will integrate with the database by an IDE (Eclipse), but it is the system that will do this.

Hi Thiago,

With SmartGWT (Pro and above), you can save screen definitions in XML and load them at runtime:

http://www.smartclient.com/smartgwtee/javadoc/com/smartgwt/client/rpc/RPCManager.html#loadScreen(java.lang.String,
com.smartgwt.client.rpc.LoadScreenCallback, java.lang.String[])

So you could build some kind of editing interface that allows new screens to be designed, then save them to a database or file in XML, and be able to load them at runtime using loadScreen().

You can also dynamically generate XML DataSource definitions, which contain data validators and other business rule definitions, enforced on both client and server:

http://www.smartclient.com/smartgwtee/server/javadoc/com/isomorphic/datasource/DataSource.html#addDynamicDSGenerator(com.isomorphic.datasource.DynamicDSGenerator,java.lang.String)

Hum understand, I had thought of something like that, but I was in doubt because GWT (smartgwt) and compiled to javascript and have part of the RF (RequestFactory), but I've thought a one implementation. Without wanting to abuse his good vontante you have an example of a loading screen.

There are samples of using XML screen definitions in the SmartGWT EE Showcase under the folder "Component XML", but you have to download a 4.0 build to get them:

    http://smartclient.com/builds

The Component XML overview explains how to provide dynamic Component XML that's stored in a DB - see "Dynamic Component XML":
