Description

Some color widgets throughout the layer properties dialog (line color for diagrams, options of symbol layer type) have a "Transparent fill/Border/outline" checkbox in their drop-down menu.
Check that option and the color becomes transparent.
But once transparent, the checkbox remains unchecked, leading to inability to remove that transparency without opening the "Choose color" dialog.

Mathieu, assigning this to you as you recently work with symbols and colors. Couldn't check if it was fixed in master though.

Harissou, the transparent color menu item is a shortcut to drop the transparency value to 0. It's not a toggle or a checked state, nor meant to be.

For me, -1. That said, this color button widget is Nyall's creation, so I'll let him rule on this :)

It's a wontfix from me too... Like Mathieu said, this is just a shortcut to a transparent color rather than a toggle.

hmmmm, my bad... Sorry. I gave another look at the widget and what I supposed to be a checkbox is actually the icon of a transparent color. So just forget this as a bug report.
Thanks for your quick replies.

Would that then make sense to have a feature request to move the button to a checkbox widget so that user can easily toggle between a full transparency and another level of transparency (might be 0 or not) previous color?
