Hi

After adding theming possibilities for TableCombo and CDateTime widget, I've reopened the bug 411451 [1] for our beloved leader ;)

It is now possible to customize the Oscilloscope widget !

In order to do so, you just have to use the plugin org.eclipse.nebula.widgets.oscilloscope.css or the feature org.eclipse.nebula.widgets.oscilloscope.css.feature

An e4 sample application called "org.eclipse.nebula.widgets.oscilloscope.example.e4" is available under the /widgets/oscilloscope directory.

I've also created a documentation: please have a look at https://wiki.eclipse.org/Nebula_CSS_Oscilloscope

Good evening,

Laurent

Hi Matthias

On the latest snap of Nebula you'll find my work on "CDateTime Theming". The "css bridge" theming was pretty easy, but it was difficult to modify the CDateTime in order to make
it more customizable.

In order to do so, you just have to use the plugin org.eclipse.nebula.widgets.cdatetime.css or the feature org.eclipse.nebula.widgets.cdatetime.css.feature

Have a nice week,

Hi Matthias

Thank you for your feedback. If you have time you can update the example application, I'll be happy ;)

On my side, I've created the bug # 560694 [1] and I'll work on CSS theming for the CDateTime  widget

Have a nice day,

Laurent

Hi Laurent,

So maybe we should also add a separate sample section for the border color in the UI of org.eclipse.nebula.widgets.tablecombo.example.e4?
I could do that in case that's ok for you?

Comprehensive support for customization of the DateTime widget using E4 CSS-based theming would be great indeed.

Hi Matthias

I would like to apologize for my late answer (I was far away from Internet ;) )

I'm very happy if you appreciate this work !!

If you want to customize the border color, you have to use the property "tablecombo-border-color". There was an error in the documentation, it is fixed now.
Here is an example extracted from [1]

TableCombo#two {
      font: Verdana 11px;
      background-color: darkred;
      color: white;
      tablecombo-show-table-lines: true;
      tablecombo-show-table-header: true;
      tablecombo-border-color: red;
}

If I remember well, you wanted also the possibility to custom the "date time" widget.
Is it still ok for you ?

Have a nice day,

Laurent

Hi Laurent,

I am testing you new Table Combo CSS features and so far, your new features and the table combo CSS sample app work fine in my IDE.
Great work!

One small thing, though:
There's  support for setting the border color by a CSS property in the  TableComboPropertyHandler, but none in the sample app nor in the documentation - did I miss something?

You'll notice a little improvement : you can change the color for the border of the widget ;)

Have a nice week-end,

Hi Paul,

Well, to be honest I have time and I like to improve myself in subject I'm not good at.

If you can help me for testing, I can create plugins for TableCombo and CDateTime that handle css properties.

If you agree, I'll create entries in Bugzilla and work on it this week.

Cheers,

Laurent

Hi Laurent,

Merci for the quick response.
Indeed, it's E4 theming I was referring too.

Nebula widgets we were not able to style satisfyingly were in particular the TableCombo and the CDateTime widget (for the TableCombo the text field border and the button do not seem to be accessible for theming, while with the  CDateTimeWidget more or less the background only can be styled).
Yet, I do not ask someone else to fix this, but hope to come up with some support for that in the code base of the widgets by myself. 

But it would be nice when new widgets came along with the required CSS properties for E4 theming quite from the beginning.
If help is welcome here, I'd be willing to lend a hand (however, unfortunately I cannot  promise constant and quick response).

Hi Matthias,

Thank you for your message. I wrote many new widgets and I have to admit that I did not take care of this aspect (probably because I'm not able to work with the Dark Theme of Eclipse or VSCode).

When you are talking about theming, you're talking about e4 theming, right ? (like the dark mode in Eclipse)

Can you tell what widgets cause problem in your application ? Or post a screenshot if possible ?

Thank you for your feedback,

Laurent

Hi all,

I see a lot of new widgets being added to our beloved Nebula lately which is great!
Yet, I wonder whether also support for theming is considered by the authors when creating the first release versions for them?

Using a lot of the "classic" Nebula widgets in our RCP application (that includes theming as a matter of course), we noticed that theming support is rather sparse for the Nebula widgets so far; in my opinion, this is some sort of drawback for the acceptance of the Nebula widgets these days since good theming support is naturally expected by users of modern RCP applications.

Hence, I think it would be reasonable and productive to take theming support for new Nebula into account quite from the start.
