Problem creating custom gwt theme

[mitratul]

Hi,

I am trying to create my own theme and use it. But while launching Dev
mode, it is giving the following errors in eclipse console:

Initializing AppEngine server
Loading modules
com.mitratul.theme.standard.Standard
Translatable source found in...
[WARN] No source path entries; expect subsequent failures
Bootstrap link for command-line module
'com.mitratul.theme.standard.Standard'
Linking module 'com.mitratul.theme.standard.Standard'
Constructing StandardLinkerContext
[ERROR] Primary linker is null. Does your module
inherit from com.google.gwt.core.Core or com.google.gwt.user.User?

com.mitratul.theme.standard.Standard is my theme module. I have
followed the same directory structure inside the module as i found
inside GWT inbuilt themes.

Can anybody tell me why is this error coming?

Thanks
Ratul

Ensure that your "theme" module "inherits" from
"com.google.gwt.user.User" so as to get a "default-linker".

Your theme has to be <inherit/>ed in an application, not compiled
standalone.

(this is from an old thread I know, but the question hasn't been answered fully in this forum anywhere I see)

So I want to create a custom gwt theme. To do this, I created a standalone maven project with a similar dir structure that I see with the gwt standard theme inside gwt-user.jar. I package it as a jar so it looks like this:

com/mycompany/mytheme/StandardRTL.gwt.xml

com/mycompany/mytheme/Standard.gwt.xml

com/mycompany/mytheme/StandardResources.gwt.xml

com/mycompany/mytheme/public/css/standard.css

com/mycompany/mytheme/public/css/standard_rtl.css

com/mycompany/mytheme/public/images/thumb_vertical.png

com/mycompany/mytheme/public/images/circles.png

com/mycompany/mytheme/public/images/vborder_ie6.png

com/mycompany/mytheme/public/images/thumb_horz.png

com/mycompany/mytheme/public/images/vborder.png

com/mycompany/mytheme/public/images/corner_ie6.png

com/mycompany/mytheme/public/images/hborder_ie6.png

com/mycompany/mytheme/public/images/circles_ie6.png

com/mycompany/mytheme/public/images/corner.png

com/mycompany/mytheme/public/images/hborder.png

then I specify this mytheme.jar as a maven dependency on a gwt project, the idea being that more than one project will use it. In the gwt project, I inherit my custom theme in my gwt module file like this:

<inherits name='com.mycompany.mytheme.Standard' />

and all css styles from standard*.css are used so it works fine, *except* for the images which are simply not used/found.

What do I need to do so that the images are found and used properly when referenced from the css file? (how are custom themes supposed to be packaged?)

I realized soon after posting how to solve my problem... so here's the solution; you have to use the path conventions that the gwt themes use so that your resources can be found. I should have known that because long time ago I got a custom theme from the GWT Theme Generator (http://works.sen-sei.in/gtg/). The css and image files need to be in the public directory and then follow a "gwt/{projectName}/" subdirectory, so the project looks like this now:

com/mycompany/standard/StandardRTL.gwt.xml

com/mycompany/standard/Standard.gwt.xml

com/mycompany/standard/StandardResources.gwt.xml

com/mycompany/standard/public/gwt/standard/standard.css

com/mycompany/standard/public/gwt/standard/standard_rtl.css

com/mycompany/standard/public/gwt/standard/images/thumb_vertical.png

com/mycompany/standard/public/gwt/standard/images/circles.png

com/mycompany/standard/public/gwt/standard/images/vborder_ie6.png

com/mycompany/standard/public/gwt/standard/images/thumb_horz.png

com/mycompany/standard/public/gwt/standard/images/vborder.png

com/mycompany/standard/public/gwt/standard/images/corner_ie6.png

com/mycompany/standard/public/gwt/standard/images/hborder_ie6.png

com/mycompany/standard/public/gwt/standard/images/circles_ie6.png

com/mycompany/standard/public/gwt/standard/images/corner.png

com/mycompany/standard/public/gwt/standard/images/hborder.png

and it works... that's what I get from trying to optimize/modify the structure I copied from the GWT Clean theme.
