panel transparency in 4.12.

Hi, 

It seems that panel transparency is broken in the 4.13 branch...

Attached a screenshot of what I do with 4.12.

Is this regression handled ?

Regards
JP

The transparency setting is not a separate setting anymore but instead has been moved into the colorpicker, because Gtk3 provides this feature out of the box now.
So you can use the color picker to apply an alpha.

Did I understand your question correctly?

Hi, 

Thanks for you answer. Please could you make it clear how I can turn on "total transparency" on the new version of the panel, as easily as before, from the XFCE panel preferences dialog ?

It's not clear for me... (although I'm a developer) : I don't get WTF is a "colorpicker" ...

Please take a look at the screenshot I provided above. 

Thanks
JP

Screenshot including panel

I also agree that something changed radically in how transparency is set for the panels in XFCE 4.13. The screenshot shows that both the icons and the panel background are faded, not just the background. I used to be able to have the icons on a fully transparent background (opacity set to 0) and the icons would appear to be floating over the screen background. Now if the opacity is set to 0, the icons are also fully transparent, not just the background. This is a major regression!

What's this ? written in Klingon ?

Is this part of the default GUI provided by XFCE ?

you wanted an alpha channel for the panel, the video shows how to get it. no additional software is used for this purpose. everything is in the Xfce panel settings.
Comment 7 Stephen Haffly 2018-11-06 15:31:51 CET
Please consider adding this information to the help files. Since I can't read the text in the video, having one done in English would be helpful, especially if it had a voice description of the new settings, not just music in the background.

I was finally able to figure out the transparency so it is not a bug. It is currently just not adequately documented. I could not find anything in the list of changes that describes this new behavior.
Comment 8 HYPERION 2018-11-06 16:46:17 CET
please provide a clear documentation about the xfce-panel GUI option that allows to configure transparency : as far as I know : there's no way to do it unless tweaking GTK3 CSS files. 1% of the XFCE USERS WILL BE ABLE TO MODIFY THE GTK3 THEME TO MAKE THE XFCE PANEL TRANSPARENT

So i's a MAJOR REGRESSION.

I've finally gotten round to writing a HowTo, it's really straightforward, please check it out.

Comment 10 Simon Steinbeiss editbugs 2019-04-19 17:35:41 CEST
I'm closing the report as invalid for now as the documentation how to achieve the same result as in 4.12 is now provided and the feature is still there.
