Hi,
I had a short look at your demo. You are mixing up two approaches to
create custom widgets. Either you use composition like you're doing in
the ApplicationHeader class, or you write a custom widget from scratch
that is completely build on a clientside javascript representation. The
widget instance itself works as stateholder on serverside.
Note that only the second approach currently allows individual theming
out of the box. But we are currently working on a enhancement of the
current theming mechanism that will allow to define style-class like
entries in the theme properties definitions. With that in place you will
also be able to style widgets created with composition.
By the way I didn't find the gradient fill in your code. Rendering
Gradients is currently not supported with RAP - so I was wondering if
some unsupported API sneeked into...
Ciao

Betreff: Custom widgets and Themes
Hi,
I am trying to write a custom widget to put a logo and text in a
Composite. I created a widget ApplicationHeader that extends composite
and created two labels (one for the logo and one for the text). I
created the LCA class, themes file and javascript files as explained in
the help documentation. I have also registered extensions for resources
and themablewidget.
The custom widget shows the logo and the text. Now I am trying to set
the background image (with gradient fill) for the composite and also
custom theme keys for the font for the title text. I have a few
questions. Basically I do not understand how all these different pieces
glue together. I looked at the various widgets defined in RAP and also
some examples posted in the newgroup. I still don't understand how all
these work together.
1. The background image for my custom widget and the gradient fill does
not show. I have defined the backgroundImage and backgroundRepeat
properties in the javascript files and also provided the apply method.
I have the background image file in resources directory under the plugin
directory.
2. How can I define custom theme keys for the title label widget. I
don't want to use the generic widget.font key. I want to define
somehting like applicationheader.title.font. How can I do that.
Thanks
Anand

Frank,
Thanks for the reply.
The reason I am doing this is to get gradient fill (since it is not
currently supported by RAP).
I got most of it to work. The LCA class was not getting invoked because
of package naming. Now I am able to see the logo, title and able to
change the title's font and foreground using theme file. But can't get
gradient to work.
I tried to copy the javascript code from qooxdoo It is is in
ApplicationHeader.js (in my plugin that I attached earler).
/**
* Mapping to native style property background-repeat.
*/
backgroundRepeat: {
check: "String",
nullable: true,
apply: "_applyBackgroundRepeat",
themeable: true
}
},
_applyBackgroundRepeat: function(value, old){
value ? this.setStyleProperty("backgroundRepeat", value) :
this.removeStyleProperty("backgroundRepeat");
}
I was trying to set the backgroundImage on my widget (which extends
composite) and set backgroundRepeat to "repeat-y".
I can't figure out what the targetPath should be in my theme xml file.
If I provide a "default" for image, I get an exception saying my image
file was not found. I have my image in
resource/widgets/applicationheader. If I specify this as the "default",
I get exception. Also, I don't understand where the image gets copied.
I looked into the target path. I don't see the image. I see it in
resource/Themes/Default/widgets/applicationheader directory.
One of the thing that I am trying to do is to let applications to
provide content for the application header. So I am creating an empty
composite in ApplicationHeader, which applications can use to add
content to the header. If I write my custom widget from scratch, will I
still be able to do this? How would I do that. Basically, I want a
method getHeaderContent() in ApplicationHeader that returns an empty
composite.

Hi,
If, in my <Widget>.theme.xml I have define the following, I get
IllegalArgumentException saying the image file is not found.
<image name="applicationheader.bgimage"
description="Background image for application header"
targetPath="applicationheader/headerBgGradient.gif"
default="resource/widgets/applicationheader/headerBgGradient.gif "/>
I looked at the registerThemeableWidgetImages method, it is trying to
load the image using the ThemeManager's class loader.
ClassLoader classLoader = ThemeManager.class.getClassLoader();
What is the purpose of the "default" attribute in the themes xml file?
If the theme manager is trying to load the image, will it find the
image, since the ThemeManager's class loader is being used, will the
resource defined in my plugin be visible to the theme manager's class
loader?

Hi Anand,
you're right, this is a bug in the ThemeManager. Thanks for pointing this
out. I filed https://bugs.eclipse.org/bugs/show_bug.cgi?id=220162.
This will be fixed with high priority, probably today or tomorrow.
Best,

Ralf,
I got the latest from CVS (again). This time it worked. I don't see the
exception anymore. But the image does not show up in my UI. I have a
custom component that extends Composite and I have the appearence defined as
appearances = {
// BEGIN TEMPLATE //
"application-header": {
style: function(states){
return {
backgroundImage: "aapplicationheader.bgimage",
};
}
},
"application-header-title": {
style: function(states){
return {
textColor: "applicationheader.title.foreground",
backgroundColor: null
};
}
}
// END TEMPLATE //
};
the textColor works, but the backgroundImage does not.
Thanks
Anand
