[GTK] Toggle buttons are blurry with GTK+ 3.19

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Michael Catanzaro]

Since 3.19.7 we can get at min-width and min-height as style properties:

https://git.gnome.org/browse/gtk+/commit/gtk/gtkcssstylepropertyimpl.c?id=ea69bf8c17dd5c9e7f76bf3cb4f56ec07b2e821f

According to Company, we need to use these by default, rather than indicator-size. If either one is zero, ignore them and fall back to indicator-size. That should fix our blurry toggle buttons (checkbuttons, radio buttons).

We should also audit all our other uses of style properties to make sure we're matching GTK+ 3.19.

Thanks, I presume you tested it.

Look what style checker caught: gtk_style_context_get_state (

> Source/WebCore/rendering/RenderThemeGtk.cpp:555
> +        minSize.setHeight(minHeight);

Company's suggestion was to do this:

if (minWidth && minHeight) {
    minSize.setWidth(minWidth);
    minSize.setHeight(minHeight);
}

Any particular reason for not following that?

Ditto

Ditto

To be 100% absolutely exact, it's

if (minWidth)
  minSize.setWidth(minWidth);
if (minHeight)
  minSize.setHeight(minHeight);

because that's what the code in https://git.gnome.org/browse/gtk+/tree/gtk/gtkbuiltinicon.c#n56 essentially does.

Which is exactly what the patch does.
