Re: fundamental problems with predictive layout
you have to call force layout to calc sizes in the new space. k Sent from my iPhone On Sep 1, 2012, at 6:09 PM, Magnus wrote: > Hi, > > since I use GWT I have a fundamental problem with implementing a predictive > layout.

Re: GWT 2.4.0 - DataGrid - Differentiating between single click and double clicks on rows
sink a mousedown event and use a static double click bool flag when u see a
click check flag if its up the its a double click and reset the flag if not
then is a single click. add a timer too that will reset the flag after a delay
of like 100ms or something.

Re: Best serverside architecture(framework/stack) to use with GWT for large application...please show me the light
hibernate with jpa beans. run onto of a restful java servlet to serve up your DAL. if your not good with dep inj design use GIN and Guice for instantiating your widgets and composites. also if your new to gwt use the ui binder. advanced create a viewport and screen manager to inject your classes. and oracle for db since it works nicely with run native behind the scenes of your plsql views that u create in your db. also for quick and dirty apps use springroo to architect and develop your back end.

Re: Login form auto-complete and GWT-RPC (or RequestBuilder), a solution!
forms??? thats so 2000s. use event based design like u mentioned and submit via restful. using post get or update or whatever ur backend or api require. sometimes u need to use forms for file xfer or other specialized means. just keep in mind that not using forms can and does break usability / accessabilty guidelines. but then again i was never good at coloring or following the rules.

Re: CellTable - style specific columns
use css selectors to id your datagrid or cell table container. and by use child
and exclusion selectors u should be able to spefic the style on the td. u can
also use css expressions or some jsni for quick and dirty impl. however i woukd
implement it using my own custom cells to render via safe html templates. this
would allow u to not only wrap the inner content with a div for overflow
handling and or tooltips. iylt would also be the easiest way to specify a class
and or id name or other atreibutes. u could crawl it with the dom and element
methods but i dont recommend that
