WebKit2.WebView.prototype.set_background_color

function set_background_color(rgba: Gdk.RGBA): void {
    // Gjs wrapper for webkit_web_view_set_background_color()
}
  

Sets the color that will be used to draw the web_view background before the actual contents are rendered. Note that if the web page loaded in web_view specifies a background color, it will take precedence over the rgba color. By default the web_view background color is opaque white. If the rgba color is not fully opaque, the parent window must have a RGBA visual and #GtkWidget:app-paintable property set to true, for the transparencies to work.

<informalexample><programlisting> static void browser_window_set_background_color (BrowserWindow *window, const GdkRGBA *rgba) { WebKitWebView *web_view;

if (rgba->alpha < 1) { GdkScreen *screen = gtk_window_get_screen (GTK_WINDOW (window)); GdkVisual *rgba_visual = gdk_screen_get_rgba_visual (screen);

if (!rgba_visual) return;

gtk_widget_set_visual (GTK_WIDGET (window), rgba_visual); gtk_widget_set_app_paintable (GTK_WIDGET (window), TRUE); }

web_view = browser_window_get_web_view (window); webkit_web_view_set_background_color (web_view, rgba); } </programlisting></informalexample>
