From 3cbce9896b9fab95b05399680706057aeb4ae96d Mon Sep 17 00:00:00 2001 From: Samuel Creshal Date: Fri, 19 Mar 2010 21:08:28 +0100 Subject: [PATCH] Implement page icon based tab colors Colorful Tabs now uses the icon of a page as the basis for the tab color, if it has one, otherwise falls back to the previous address based hash. The forground color is also adjusted for dark colored tabs. --- extensions/colorful-tabs.c | 110 +++++++++++++++++++++++++++++-------- 1 file changed, 88 insertions(+), 22 deletions(-) diff --git a/extensions/colorful-tabs.c b/extensions/colorful-tabs.c index 01a0bd7b..d9c108ef 100644 --- a/extensions/colorful-tabs.c +++ b/extensions/colorful-tabs.c @@ -1,5 +1,6 @@ /* Copyright (C) 2009 Christian Dywan + Copyright (C) 2010 Samuel Creshal This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser General Public @@ -11,56 +12,118 @@ #include +static void +colorful_tabs_modify_fg (GtkWidget* child, + GdkColor* color) +{ + if (GTK_IS_LABEL (child)) + { + gtk_widget_modify_fg (child, GTK_STATE_ACTIVE, color); + gtk_widget_modify_fg (child, GTK_STATE_NORMAL, color); + } +} + static void colorful_tabs_view_notify_uri_cb (MidoriView* view, GParamSpec* pspec, MidoriExtension* extension) { + GtkWidget* box; GtkWidget* label; SoupURI* uri; - gchar* hash; gchar* colorstr; GdkColor color; + GdkColor fgcolor; + GdkPixbuf* icon; label = midori_view_get_proxy_tab_label (view); - /* Find a color that is unique to an address.
