Bug 50225 – [GTK] Use gtk_widget_render_icon() to render media buttons using gtk stock icons

• Component: WebKitGTK
• Status: RESOLVED DUPLICATE

[Carlos Garcia Campos]

gtk_widget_render_icon() returns the right version of the icon depending on the widget direction, so we don't need to change the icon name. It also uses the gtk icon cache, so we can avoid loading the icons from files.

Great. Just a couple small issues.

I think you should just use this this directly.

> +        RefPtr<BitmapImage> img = BitmapImage::create();

No need to cache this. You can simply return BitmapImage::create();

> WebCore/platform/gtk/RenderThemeGtk.cpp:91
> +    RefPtr<BitmapImage> img = BitmapImage::create(surface);
> +    return img.release();

Same here, I believe.

It also uses gtk_widget_render_icon() for search entry icons.

This patch seems to contain some bits from your other media styling patch. Other than that it looks pretty good. I have a few comments.

Consider using a PlatformRefPtr here.

Instead of basing this on the size of the icon, it should be based on the height / width of the search box. Otherwise the icon might paint outside the box or be very small in relation to the field size.

Now might be a good time to make searchImage a member of RenderThemeGtk so that it can be properly freed.

> WebCore/platform/gtk/RenderThemeGtk.cpp:524
> +    static Image* cancelImage = loadStockIcon(GTK_WIDGET(gtkEntry()), GTK_STOCK_CLEAR, GTK_ICON_SIZE_MENU).releaseRef();

Maybe time to make this a member as well?
