From 3c832377fb4c4b32fcbdbc60fdfedb57296bc8c0 Mon Sep 17 00:00:00 2001 From: Antony Lee Date: Sun, 31 Jan 2021 18:54:43 +0100 Subject: [PATCH] Set the GTK background color to white. This is consistent with the other backends (although this seems to be broken on wx too), which allows semi-transparent figures to be rendered against a consistent background (this can be checked e.g. with `figure(facecolor=(0, 0, 0, 0))` or `figure(facecolor=(1, 1, 1, .5))`), which would previously be rendered differently on gtk3 when using a dark theme. --- lib/matplotlib/backends/backend_gtk3.py | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/lib/matplotlib/backends/backend_gtk3.py b/lib/matplotlib/backends/backend_gtk3.py index 68e43ca2b32b..86fd208e1226 100644 --- a/lib/matplotlib/backends/backend_gtk3.py +++ b/lib/matplotlib/backends/backend_gtk3.py @@ -127,6 +127,12 @@ def __init__(self, figure=None): self.set_can_focus(True) + css = Gtk.CssProvider() + css.load_from_data(b".matplotlib-canvas { background-color: white; }") + style_ctx = self.get_style_context() + style_ctx.add_provider(css, Gtk.STYLE_PROVIDER_PRIORITY_APPLICATION) + style_ctx.add_class("matplotlib-canvas") + renderer_init = _api.deprecate_method_override( __class__._renderer_init, self, allow_empty=True, since="3.3", addendum="Please initialize the renderer, if needed, in the " pFad - Phonifier reborn
