Difference between gwt-ext and ext-gwt

由 末鹿安然 提交于 2019-12-03 12:26:24
Am I taking crazy pills, or are these two things pretty much identical? Having spent significant time with both frameworks at this point I would say that they are not "pretty much identical". While they may both use the same graphical assets, the way that they go about getting there is very different and depending on your needs/development style you may find one preferable to the other. GWT-EXT encapsulates Ext-JS by wrapping the Ext-JS framework which can lead to frustration when attempting to extend functionality because you don't have access to the implementation at a low enough level.

How can I tell what events fire from GXT?

由 百般思念 提交于 2019-12-03 10:20:00
问题 I cannot seem to find any documentation of what events fire and when in GXT. The API docs have lists of all the events that could fire (in Events ). And it describes how to handle events that you catch. But I'm interested in the opposite side, which events are fired when I take a certain action. I can set some listeners for various different components, or I can use addListener with a specific event code to catch individual events. That's spotty, and I seem to be using trial-and-error to

How to configure Ext GWT with GWT Designer?

由 房东的猫 提交于 2019-12-03 10:08:51
问题 I have problem with configuration GXT with GWT Designer. I have all new releases of Eclipse, GWT plugin and GXT and cannot configure GXT to work with GWT Designer. I setup my project so that I can compile my GXT project and run it in browser. However I can't design in GWT Designer. I don't see any GXT widget in GWT Designer. All forums reffer to Google Web Toolkit -> Configure for using Ext-GWT (GXT) but I don't have this option. I have done all steps defined in setup.txt of GXT. The only

Design patterns for enabling user interface elements based on user permissions?

由 杀马特。学长 韩版系。学妹 提交于 2019-12-03 05:13:52
问题 We have a web application and its front end is implemented with GWT/GXT. Users can belong to various groups and these groups can then have various permissions. The permissions are quite fine grained, for example comment_create, comment_edit, comment_delete and comment_read. What would be the best way to enable and disable user interface controls based on user permissions? We have an utility method that returns boolean value with given user and permission name. But at the moment each control

@Override is not allowed when implementing interface method

由 冷暖自知 提交于 2019-12-03 00:37:18
问题 I have the problem mentioned in the title. You could say that this thread duplicates another one: How do I turn off error validation for annotations in IntelliJ IDEA? But the solution given there doesn't work. They say that I need to take the following action: In the Project Structure | Project dialog, change the Project language Level to 6.0 - @Override in interfaces. However, the Project language Level is 6.0 at the moment, but I still see the error. Vic, here is the window and there is no

GWT or not for enterprise apps

由 别等时光非礼了梦想. 提交于 2019-12-02 21:29:43
I am working on an tool to create enterprise level applications on app-engine. This needs to be cross browser (also including IE8), works on mobile, and at a later point of time also supports desktop clients through (Qt4/GTK/etc) The problem that I consistently face is this: For my web-application - should I use GWT(GoogleWebToolkit) or not? I am pretty good at using "EXT-JS", but its not a choice due to its open-source policy. There is another framework "SmartClient" which has a better opensource license- Its pretty mature and better than EXT-JS (based on some POCs), but its documentation
