I am not a web application pro but need to start working on a project so I need to know if pyjamas ( or shall I say the javascript generated o/p of pyjamas ) is as good as pyqt in terms of 2d graphics and widget features. I have a desktop python application which has some rich 2d graphics (with animations / collision detection etc..) implemented using pyqt.
Now I am specifically looking for equivalent web client with similar graphics and widget features . Does pyjamas support all the pyqt UI features with same look and feel??
I am also exploring GWT for this since I believe GWT has a good set of UIs and also supports decent 3rd party tools like vaadin,smartgwt but my preference is for pyjamas because its python and I am writing a equivalent pyqt based desktop app so am more comfortable with python then java. Also am not sure if GWTs look and feel would match with that of pyqt based UI on windows.
Any insights would be very helpful
Thanks in advance

Probably too late, but if anyone else would need an answer,
Pyjamas' widgets are mostly same as GWT's (most are direct translation from GWT, but we have some own widgets too), and do not target Qt, GTK or any other toolkit.
If you are looking into using webkit, you could get best of the two worlds, and use Pyjamas with PyJD. This way your very same application could be compiled into html/css/javascript and run in web browsers and at the same time you could run it in pyqt-webkit, xulrunner or mshtml with original python code.

I have been working on a project model and pretty much completed it. Now I must implement the view of the project. I like eclipse view layout very much and tried to implement like this but I couln't. And then download source code of eclipse but couldn't find my specific code snippet in all of the source code. I mean I want to take basic layout implementation like eclipse Coolbar,ctabfolder and events. any suggections ?
Thanks.
If you like the Eclipse look and feel and the components used, you should have a look into the technologies used with Eclipse:
SWT is the GUI toolkit. It differs from Swing in that it uses the native widgets, if possible. This makes an application using it behave more like a native application than Swing does, which has its own set of components. You will find the raw components that you mention here.
JFace is an application framework based on SWT. It provides higher level conceptual components.
Eclipse RCP is a platform for building application. It takes away some common tasks of application building but, of course, you need to learn the concepts first.
Swing has similar components, but does not use the native widgets. It draws them itself. In my opinion Swing is easier to learn and to use but the results of SWT are often nicer - you can often "feel" that a Swing application behaves not completely right. It is better if Swing applications do not try to mimic the native look and feel to avoid the uncanny valley effect. So expect your resulting application to look and feel different.
There are more documentation and third-party libraries available for Swing, for example the very nice Netbeans RCP that let's you easily build applications.
What you are looking for is a docking framework. What the best framework is is open for debate.
You might have a look at this question for a list of popular frameworks
Is there any good browser plugin that has Python as its primary scripting language. It is ok even if it has very minimal graphical abilities like just taking inputs through HTML forms or parameters and rendering text as output.
One option is running Python on server side. But unfortunately, I am not allowed to install any Python server side framework.
EDIT
It seems that Silverlight can use IronPython as its language. But any other more cross platform solutions are still welcome.
You can look at the PyXPCOM add-on to Firefox. It seems to do what you're looking for.
I'd like to try out WebGL but do not like JavaScript that much. Are there any *-to-JavaScript compilers like GWT (Java to JavaScript) which you can recommend for WebGL development?
GwtGl allows the use of WebGL in a GWT project.
I've found gwt-g3d to be the best.
Examples worked the first time for me and it comes with lots of useful utilities e.g. common shader types, common matrix functions etc.
I also vote for GwtGL! It was very easy to write WebGL applications with this wrapper. I can use all benefits from Java and interact with other, state of the art, javascript libraries like gl-matrix to get matrix functions. I've written some posts how to use GwtGL based on the famous learningwebgl.com tutorials here http://gibberfish.net/learning-webgl-lesson-1-with-gwtgl/.
is there a difference between Ext GWT and GWT-Ext? Cos i was surfing Ext GWT and saw this page http://gwt-ext.com/demo/. any help guys?
ExtGWT is marketed and maintained by the same guys who developed ExtJs library. ExtGWT shares its look and feel and API structure with ExtJS. Contrary to popular perception, ExtGWT is not a wrapper around ExtJS javascript, but written ground up using GWT DOM and other low level GWT API's. It is 99% java based and uses no (or very little) JSNI to get things done. It also supports data binding. This library is actively supported and also has a paid commercial version.
On the other hand GWT Ext was developed by Sanjeev Jeevan as a wrapper around LGPL version (no support now) of ExtJS. So the library is a very shallow wrapper around ExtJS javascript and uses JSNI extensively. This can create problems, particularly if you need to debug the library. GWT Ext does not enjoy the same level of community support as ExtGWT and also the original author has long since moved on to a different project. Read about the reasons here.
If you have to choose between the two, and plain old GWT is not an option, choose ExtGWT. Keep in mind that it is GNU GPL licensed.
Neither. You'll have nothing, but problems with third-party GWT widget libraries. I've wasted four years on significantly more refined and mature SmartGWT and finally gave up.
Styling standard GWT components that wrap native browser controls is easy. You should strive for native portable control set and you'll rarely need anything more for a modern minimalistic mobile-friendly UX. However if you still crave some third-party widgets, look at GWT-Bootstrap3: https://github.com/gwtbootstrap3/gwtbootstrap3
Well the topic says it all. Can I use google web toolkit to generate my views to be used in Castle Monorail project and render it through nvelocity view engine. Is it at all possible?
I don't know of anyone that has tried this, but GWT is a server-independent technology so in principle I don't see why it wouldn't work. GWT needs some server-side plumbing which you'll probably have to write yourself (again because I haven't found anyone that has done this before).
You might want to check out Script# which is similar to GWT but you code in .Net, it has MSBuild support, Visual Studio integration, etc.
