31 // This implements the WebThemeEngine API used by the Windows version of
32 // Chromium to render native form controls like checkboxes, radio buttons,
34 // The normal implementation (native_theme) renders the controls using either
35 // the UXTheme theming engine present in XP, Vista, and Win 7, or the "classic"
36 // theme used if that theme is selected in the Desktop settings.
37 // Unfortunately, both of these themes render controls differently on the
38 // different versions of Windows.
40 // In order to ensure maximum consistency of baselines across the different
41 // Windows versions, we provide a simple implementation for DRT here
42 // instead. These controls are actually platform-independent (they're rendered
43 // using Skia) and could be used on Linux and the Mac as well, should we
44 // choose to do so at some point.
