Stylize status overlay

Files devs, does this element currently have a theme-able class? If not, can we create one?

The name of the widget is "MarlinViewOverlayBar". The problem is that it has a built-in CSS stylesheet that is not overridable from the user's theme. I will lower the priority of that stylesheet and mark this bug as fixed for pantheon-files.

Daniel, it's all yours now. Please use the "files-overlay-bar" style class.

Okay, so I ran into so problems. It looks like status overlay doesn't accept padding, but also border-radius and transparency don't work. There is some kind of background behind this widget.

Daniel, all the problems you've mentioned are fixed now.

Okay Victor, a couple more things xD

1. In the attached screenshot you can see that there are little gray corners here for some reason.

2. Is there a way to add padding around the outside of this box so it's not directly up against the side of the window?

You need to set the EventBox's child window to be invisible (the one recieving events)
http://www.valadoc.org/#!api=gtk+-3.0/Gtk.EventBox.set_visible_window

i.e. yourEventBox.set_visible_window (false)
You want to avoid any dependency on GTK drawing via extension methods, instead rely
solely on a cairo drawing function (using the draw event, cairo's expose)

This should correct the issue for you (Also ensure to pad the rectangle clipping 1 or 2px)

Ikey, thanks for the suggestion! I forgot to set that property to false. Drawing directly with Cairo is not recommended in this case though, because we want full theming support, and the family of gtk_render_*() is there to give us that for free.

Daniel,

> 1. In the attached screenshot you can see that there are little gray corners here for some reason.
Yeah, I forgot to do what Ikey suggested above.

> 2. Is there a way to add padding around the outside of this box so it's not directly up against the side of the window?
Yes, it is :) Although we're no longer talking about padding here, but the "margin" style property. The correct order is margin/border-width/padding, where padding refers to internal spacing. Margin support is still not implemented, but I'll add it as soon as possible.

Again, all fixed. Please mark the bug as "fix committed" if everything works as you expect.

Glad I could be of assistance (And quite happy to see that GTK3 is now much more willing to listen than it previously
was :))

Looking sexy, marking both as fixed. Thanks Victor (and Ikey!)
