Is there a datawindow color magic number for theme background and foreground?

Like there's 553648127 for transparency and 1073741824 for Window Background?

If all else fails, then create a new button on the window with the appropriate colors set and hide it with a taborder of zero.

When you need it, take the current button, set the taborder to zero, and hide this button. Then take the OTHER button - the one with the color you want - set the taborder to the correct taborder of the button, set the X and Y coordinates to that of the original button, and SHOW the button.

How about setting a different color button for a particular button through the theme?  UI Themes support making exceptions to apply a different theme to a particular instance of an object rather than global.  Please refer to the "Custom theme definition files for selected objects or controls" section in this tech article: https://community.appeon.com/index.php/articles-blogs/tutorials-articles/2-powerbuilder/301-applying-a-new-ui-theme-to-your-application-2

Hi Tomas.

In this specific case inheritance won't help.

I don't believe that you can change dw button's background color when a theme is set. Neither setting an expression with modify or in dw painter will work unless you are not using a theme.

Hi Andreas

What is the exact version of PB you are using?

- PB2021 and PB2022. I tried both and the result was always same. So I think this is intentional.

What are those cases?

- Anything where you need a user's focus at the button. Like:

  There are new records or events touching this topic

  There are new replies to this thread

  The time is Over (at button 'Done' in a tasklist)

Maybe you could achieve what you want with inheritance and custom themes...

- I'm not sure I understand you. The idea is: The button has to be red if some conditions based on the business logic are met. Otherwise the theme color is used.

- I've observed that for columns the theme is applied only at the creation point. So I can easily modify background.color. For buttons this is not possible (or I haven't found how to do it).

- Of course it would be nice to have classes for datawindow objects like CSS class in HTML and power to change the class with "modify" or datawindow expressions. But this is not there at this time.
