[e4-dev] CSS only in E4 now?

[Werner Keil <werner.keil@xxxxxxx>]

Hi,

 

I know this list seems very low-traffic, so not sure, if it still has enough active participants, but as I found a thread about E4, E3 and CSS here (https://www.eclipse.org/lists/e4-dev/msg02893.html) let me try.

 

I help a customer update an existing E3 RCP application to Eclipse 2020, when we came across new features like the minimize/maximize buttons on every view part.

 

 

Users don’t want to have them on most views, and I came across a nice and easy way to remove them from an E4 application via CSS:

.MPartStack

{

    swt-maximize-visible: false;

    swt-minimize-visible: false;

}

 

However, this does not seem to work in the E3 generation application, is it not possible there any more to use CSS files or is there a different, e.g. programatic way to hide or disable those min/max buttons?

 

Thanks in Advance,

Werner
