Bug 34405 – MediaControlTimeDisplayElement should defer time formatting to the theme

• Component: Media
• Status: RESOLVED FIXED

[Nick Young]

Currently, there exists two media control elements which display time related information: The current time display and the remaining time display.
The inner text of these elements is defined in the MediaControlTimeDisplayElement (platform independent code).

It should be possible for the theme to decide what times are shown in these elements, and how these times are formatted.

Initial Patch

This patch addresses the problem by introducing three new virtual methods to RenderTheme:

virtual String formatMediaControlsTime(float time);
virtual String formatMediaControlsCurrentTime(float currentTime, float duration);
virtual String formatMediaControlsRemainingTime(float currentTime, float duration);

The first method can be reimplemented by those only wishing to change how the times are formatted.
The latter two methods can be reimplemented by those wishing to change what times are shown in each element.

The motivating use case for this patch is to hide the time remaining element and augment the current time element -

String RenderThemeXX::formatMediaCurrentTime(float currentTime, float duration)
{
    return formatMediaTime(currentTime) + " / " + formatMediaTime(duration);
}

> +    virtual String formatMediaControlsTime(float time);
> +    virtual String formatMediaControlsCurrentTime(float currentTime, float duration);
> +    virtual String formatMediaControlsRemainingTime(float currentTime, float duration);

These should all be const.

r=me with this change, thanks!

There's an unused parameter there. I've left it in (but commented it out) so that reimplementers don't have to guess what it is.

Why is this one the RenderTheme (which is runtime switchable) instead of part of WebCore/platform?

[Eric Carlson]

Because some platforms support more than one media controller theme?
