GNOME Calendar

gnome-calendar (Ubuntu)

Bug Description

* Impact

the gnome-calendar window corners don't look right (white squares instead of rounded)

* Test case
start gnome-calendar under unity and look at the windows corner, they should be rounded. The update also include a bugfix new revesion so make sure calendar events are correctly listed and that the calendar works correctly

* Regression potential
the update has only small bugfixes and should be safe but keep an eye for new issues


Gnome Calendar still looks like it is not using the proper CSD that other Gnome apps do (maps, weather, etc.) nor does it look like a patched Unity app.

This should be fixed in Xenial. An LTS should look more polished!

White corners are, I think, because g-cal has it's own CSS file "gtk-styles.css". Line 5 of this file sets .views to have a background colour of @theme_base_color.

Our CSS tries to override this on the GcalWindow object and set the colour to transparent. I think this is being over-ridden in turn by the hard-coded (?) gtk-styles.css. Setting our override CSS to GcalWindow.views is not effective.

In gcal-applicaiton.c:

#define CSS_FILE "resource:///org/gnome/calendar/gtk-styles.css"

Why are we using CSD at all? With gtk3-nocsd ( it works quite well. Screenshot:

Why should disable headerbar under unity and patch menubar just like we do for gedit and other apps.

Will Cooke (willcooke) wrote :

Applying this patch to gtk-styles.css in gnome-calendar and then adding the corresponding patch to the theme "fixes" the issue.

Will Cooke (willcooke) wrote :

Removing the .views CSS from the gtk-styles.css in Calendar and moving it to our Ubuntu theme's calendar.css. This needs to be applied in conjunction with the patch to gnome-calendar's gtk-styles.css

The yakkety changelog has a wrong LP bug number,

gnome-calendar (3.20.2-0ubuntu1) yakkety; urgency=medium

  * New upstream version
    - Use the theme's CSS instead of our custom one (lp: #565267)

It should be 1565267.

The changelog missed Bug #1573636. It is fixed in 3.20.2.

status: In Progress → Fix Committed
tags: added: verification-needed
tags: added: verification-done
removed: verification-needed

Actually I'm not sure if it should be marked as verification-done.

That's because as far as I can see it only resolves the problem for Ubuntu default themes Ambiance and Radiance all the other 3rd party themes still render incorrectly. Even Adwaita the default GNOME theme renders incorrectly.

Well, no plan to block something which is better just because it's not perfect. We can do another update to fix remaining issues later

I have been testing it on one of my install that pre-release updates enabled and so far it has been good.
