From 0c639b38b246484bebd7ff3b58c3ecb7fbe43272 Mon Sep 17 00:00:00 2001 From: lukefromdc Date: Mon, 12 Oct 2015 19:20:05 -0400 Subject: GTK3: Support custom panel themes and transparency This adds support for custom panel themes using the .mate-panel-menu-bar selector to control child widgets. The menus are controllled by .mate-panel-menu-bar .menu and most of the slider theme is that of the frame it is drawn in. The .mate-panel-menu-bar .frame selector will theme this frame, there is also an inner frame in the layout which will follow .mate-panel-menu-bar .frame .frame and otherwise display a second time anything specified in .mate-panel-menu-bar .frame. In most cases that can simply be set transparent. Themes can use alpha values for both menus and slider backgrounds. --- mate-volume-control/gvc-stream-status-icon.c | 28 +++++++++++++++++++++++++++- 1 file changed, 27 insertions(+), 1 deletion(-) diff --git a/mate-volume-control/gvc-stream-status-icon.c b/mate-volume-control/gvc-stream-status-icon.c index 3ede4b1..07354f9 100644 --- a/mate-volume-control/gvc-stream-status-icon.c +++ b/mate-volume-control/gvc-stream-status-icon.c @@ -250,8 +250,21 @@ on_status_icon_popup_menu (GtkStatusIcon *status_icon, GtkWidget *item; menu = gtk_menu_new (); - item = gtk_check_menu_item_new_with_mnemonic (_("_Mute")); +#if GTK_CHECK_VERSION (3, 0, 0) + /*Set up theme and transparency support*/ + GtkWidget *toplevel = gtk_widget_get_toplevel (menu); + /* Fix any failures of compiz/other wm's to communicate with gtk for transparency */ + GdkScreen *screen = gtk_widget_get_screen(GTK_WIDGET(toplevel)); + GdkVisual *visual = gdk_screen_get_rgba_visual(screen); + gtk_widget_set_visual(GTK_WIDGET(toplevel), visual); + /* Set menu and it's toplevel window to follow panel theme */ + GtkStyleContext *context; + context = gtk_widget_get_style_context (GTK_WIDGET(toplevel)); + gtk_style_context_add_class(context,"gnome-panel-menu-bar"); + gtk_style_context_add_class(context,"mate-panel-menu-bar"); +#endif + item = gtk_check_menu_item_new_with_mnemonic (_("_Mute")); gtk_check_menu_item_set_active (GTK_CHECK_MENU_ITEM (item), mate_mixer_stream_control_get_mute (icon->priv->control)); g_signal_connect (G_OBJECT (item), @@ -769,6 +782,19 @@ gvc_stream_status_icon_init (GvcStreamStatusIcon *icon) gvc_channel_bar_set_orientation (GVC_CHANNEL_BAR (icon->priv->bar), GTK_ORIENTATION_VERTICAL); + +#if GTK_CHECK_VERSION (3, 0, 0) + /* Set volume control frame, slider and toplevel window to follow panel theme */ + GtkWidget *toplevel = gtk_widget_get_toplevel (icon->priv->dock); + GtkStyleContext *context; + context = gtk_widget_get_style_context (GTK_WIDGET(toplevel)); + gtk_style_context_remove_class (context,GTK_STYLE_CLASS_BACKGROUND); + gtk_style_context_add_class(context,"mate-media-applet-slider"); + /* Make transparency possible in gtk3 theme */ + GdkScreen *screen = gtk_widget_get_screen(GTK_WIDGET(toplevel)); + GdkVisual *visual = gdk_screen_get_rgba_visual(screen); + gtk_widget_set_visual(GTK_WIDGET(toplevel), visual); +#endif #if GTK_CHECK_VERSION (3, 0, 0) box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 6); -- cgit v1.2.1
