Hi there,

I wanted to know if and how the Section widget of eclipse forms is
styleable withing RWT?
I've found no example of how to do so and just adding a 'Section' to our
theme.css seems not to work.

Thanks for any help

The Section widget is not yet themeable. Actually, the only themeable
widgets in the Forms plug-in are Hyperlink and FormText.

Since the Forms widgets are usually created by FormToolkit, which also
applies an initial styling to the widgets, I'm not sure whether theming
would be appropriate here. The theming for background color, font, etc.
would be overwritten by FormToolkit anyway.

What exactly do you try to achieve?

Best regrads,
Ralf

since we think the section widget is missing some kind of header styling
(in eclipse SWT it has a background on the title bar) we tried to create
this within RWT but failed. The styling the FormToolkit offers is not
enough in this kind of styling, since we could not add a header graphic
which is at the top of the section and repeats over the horizontal axis.

Maybe this does work when adding a styling data node
(WidgetUtil.CUSTOM_VARIANT) to the section. But we currently have not
tried this.

Any idea?

I did some work on this and we've been using it without problems.
There is a patch attached to the following ticket.

https://bugs.eclipse.org/bugs/show_bug.cgi?id=213193

The patch does the normal eclipse form heading & section heading
decoration and shading. There are some other methods that need to
be implemented as suggested in the ticket, bit it does go some way
to providing a solution. Note that it uses AWT graphics2d to do
some of the rendering.

Cheers,
Paul

thanks for that hint, but we run on a headless unix server (and no X
installed). Therefore we could not use the patch.
We could install an Xvfb but thats not an option for us.

Thanks

No it does not work. It seems that the Section widget get no styling
besides the methods from the api. :/

is there some documentation on how to implement this? The official
documentation for RWT/RAP on theming is outdated and I've found no docs
on howto implement custom theming.

Thanks

Noone asked for the custom widget theming documentation for some time,
so we put our efforts into other areas. But we will include an updated
help into the 1.2 release.

Anyway, the help that is installed with the RAP tooling is not entirely
out of date. The syntax of the theme.xml files, appearances, and also
the ThemeAdapters has changed (you can use existing RAP code as an
example here), but the steps to follow are basically still the same.

If you have any problems, don't hesitate to ask.

Best regards, Ralf

does this bug cover your problems: 213193: [Forms] Section
setTitleBarBackground
https://bugs.eclipse.org/bugs/show_bug.cgi?id=213193

If not, please open an enhancement request and list the themeable
properties that you miss. Maybe also a screenshot of the problem.

Best regards, Ralf

I'll try to create some styling code for the section. Thanks for your
help :)
I'll sure ask if I can't go on for some reason.

(And basically the bug you mentioned in the other response cover our needs)
