SmartGWT Datasource customization tutorial

Some details: I have a GWT project which uses a proprietary client-server protocol for fetching data (with an extensive API based on GWT classes). The server is non-GWT based, i.e. GWT is used only for client side. I'd like to use SmartGWT's widgets with this data by creating a custom DataSource which will interact with the existing GWT infrastructure. Does anybody know of such a resource? EDIT: Charles Kendrick's answer worked for me. For a working code example, you can see this

问题 I'm using SmartGWT/SmartClient LGPL, I can't use the Pro, due to project ties. I would like to create a RestDataSource from a jdbc connection, to be exposed from the server to the SmartGWT client. How could it be done? Any help is greatly appreciated. 回答1: Have you had a look at the source code for the RestDataSource Edit & Save example from the Showcase? It's a good starting point. If you want REST on the server I'd recommend Restlet talking to a JDBC backend. You could take the example

SmartGWT: hide a column in a grouped grid (which makes the group)

由 帅比萌擦擦* 提交于 2019-12-02 14:46:19
问题 I have a SmartGWT grid, where I want to display some data from JBoss-Server and it's grouped by one textfield that I fetch from JSON. So, but I want this textfield only in the header of each group. When I do .hideField on this field, then i'm loosing the group. grid.hideField("pool"); But when i hide it over the context-menue of the grid header, the column remains. Any idea how to do this? Roman. 回答1: There is simple and clean workaround. Just set width parameter of the filed to '0'.
