EXT-GWT and GWTDesigner

[gzoniko]

Hi,

We're currently evaluate to purchase a GWTDesigner license and had been trying to search inside forum and couldn't find much about the support of ext-gwt.
I know that ext-gwt is a new version of myGWT but wonder how well GWTDesigner support ext-gwt?

I tried to create a new project and includes gxt.jar in my project and also inherits com.extjs.gxt.ui.GXT in my project module.
However, when I try to add a com.extjs.gxt.ui.client.widget.button.Button in designer(thru Palette -> Choose Widget) , I got the following exception:

Code: Select all

Any idea? Thanks for the help!

GWT Designer does not have any support for EXT GWT yet.

That will come later this year.

Hi, just wanted to ask if there was another estimate when ext-gwt support would be added.

No. It is still planned for later this year. Probably late in Q4.

[SCAI_Andre]

Hi!

Any updates on this?

We have decided to finish support for GWT-Ext first as that seems to be much more popular.

EXT GWT (GXT) support will happen in Q1.

[MeMyself]

+1 for GXT support at the soonest possible opportunity

GXT is not really "friendly" if you don't do full open-source or commercial development, however it does have some benefits being a full GWT/Java solution/implementation and not only a wrapper around a JavaScript library. In the previous incarnation of MyGWT is was the most popular GWT library for good reasons. In our specific case we are doing commercial development with licenses for both GWT Designer and GXT. We cannot use the GUI designer features yet, but do look forward in having it available.

[Eric Clayberg]

GXT is on our short list, although I must say that we received many more requests for GWT-Ext support than for MyGWT/GXT support.

[vampie]

you should provide SmartGWT support after gwt ext support...
btw gwt-ext license has changed.. and i think only smartgwt is free and looks robust.

SmartGWT is on our list after GXT.

btw gwt-ext license has changed.. and i think only smartgwt is free and looks robust.

I know the MyGWT/EXT GWT/GXT license changed.

The GWT-Ext license change as well? It still seems to be listed as LGPL.

[vampie]

current version has LGPL but next version will be GPL v3 because of underlying EXT-JS version changed...
That is why SmartGWT born...

I have read it somewhere... you can also look about it. Supporting EXT in long term would be a trouble for commercial application
developers...

I still haven't read anything that suggests that the license on GWT-Ext is going to change.

We do plan to support SmartGWT next year.

[vampie]

gwt-ext will not change but it will stuck on ext js 2.0.2 version coz from that version ext js is GPL..
so gwt-ext will be not supporting next version of browsers...

Yes. That is my understanding. GWT-Ext is not going to change.

GWT-Ext is pretty dead long term, but it is still quite popular for some reason (we get 10-1 requests for it vs. GXT or SmartGWT).

We ar going to finish our support for GWT-Ext as best we can (some of it is too buggy to support) and then tackle GXT and SmartGWT.

Hi,
we used to use gwt-ext in our application but as gwt-ext will not be supported and the developement stops in the near future because they are going towards smartgwt, we are thinking about using ext-gwt now. Can you please give an update on progress concerning the support of ext-gwt in Gwt Designer that was planned to be realized in Q1 2009? Thank you.
