Re: Problem creating custom gwt theme

2012-04-05 Thread El Mentecato Mayor

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.

Re: Want to have another gwt module in source package. But GWT can't find it then

2012-04-05 Thread saida dhanavath

In eclipse project explorer

1. Right click on your project -->Run As-->Run configurations...
2. Select your GWT web application project
3. Open Arguments tab from right panel
4. Update program arguments, meaning remove which are not entry points in
your case "com.san.San''.

and run it again, it should work!.

This occurs in few cases, one among them is say you have created an entry
points module1 and entry point module2. the eclipse GWT plugin will add
these entry points to program parameters to be able to allow you run them
easily, in this case it will add two entry points will be added into
program parameters, and now, say  you delete module1 from the project and
try running module2 and you will end-up getting the above error because it
is not able to find module1  from the program parameters in Run
configurations...

Hope this helps you!

Best Regards,
Saida.

Re: Problem creating custom gwt theme

2012-04-05 Thread El Mentecato Mayor

(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:



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?)

Re: cannot use css background-image

2012-04-05 Thread Thad

Did you find a solution to this?

I dunno how background images behave with HorizontalPanels. My guess is 
"not well" given that HorizontalPanels are cell panels--they use HTML 
tables, not divs--and are not recommended for standards mode 
(https://developers.google.com/web-toolkit/doc/latest/DevGuideUiPanels#Standards).

That said, I have used background images in AbsolutePanels with both 
UiBuilder via sprites and plain GWT and CSS.

Displaying a Widget or a Composite in a DataGrid

2012-04-05 Thread Hervé Brun

Hi everybody !!

I'd like to know if someone ever managed to display a widget in a
datagrid's column ?
I mean, as there is a TextCell class, did anyone managed to
successfully program a WidgetCell class ?

By extension, does anyone knows if there is any way to continue to
write pure widgets inheriting Widget and use these classes in a
CellWidget ?
I find it very bizarre (to say the least) to have a Widget class and
not being able to use it in a DataGrid ... :S

Use composition rather than inheritance; or use the "inner class" trick I 
described earlier (that's entirely private to the super-class, so it 
shouldn't affect your subclasses).

Re: UiBinder view inheritance troubles

2012-04-05 Thread Márcio Menezes

Hey, guys, thanks for the answers...

Thomas, I think what u said is the cause of my problem. I have two ui.xml
files, one for the super and another for the sub class. And I'm trying to
bind both and put them together in a container afterwards.. ://
I see the limitation, "you cannot use a single class hierarchy as the
target for two UiBinders". But I didn't want to have to move the fields of
the super class to the sub or the other way around.
What I'm trying to get is a view extending from another view. Why do I want
to do this? Because I have a set of views with the same visual pattern, ie:
"CRUD" views that need to have save and cancel button, and I didn't want to
repeat my self in all the sub views by re-adding the save and cancel
button. Nothing new... Pure O.O. concepts.

Really? Isn't there a way of doing this?

Re: code splitting question

2012-04-05 Thread dodo dard

Hello,

It depends on the dependency between your module. The best way to deal with 
code splitting is to start it. And than you can analyse each your code 
splitting combination. Google provide the tools to do that.

CellTree, like all Cell widgets, is *based* on databinding (unless you 
don't have the same definition for databinding as me)

It doesn't support those features, but your model (TreeViewModel) can (most 
likely using a *decorator* pattern around you *real* TreeViewModel). The 
hardest part is to fire the appropriate events so that the CellTree 
re-renders your tree with the updated model.
I've implemented a live outline of a rich-text editor (as soon as you 
add/remove a heading, the outline tree updates; same if you change the 
heading level; and if you type in the heading, the corresponding tree item 
updates with the new heading text). In my case, I used ListDataProviders 
within DefaultTreeNodes, and to update the tree I simply replace the whole 
list (ListDataProvider#setList). When an element has changed –but not the 
structure of the list– (e.g. when a heading's text changes), then I get the 
parent node's children list and call setList with the same value, it'll 
redraw the children of the parent node, so will redraw our updated node
