Bug 53206 – SPI to temporarily disable updating the size of the drawing area during WKView frame resizes.

• Component: WebKit2
• Status: RESOLVED FIXED

[Jing]

Clients that have to call setFrame multiple times can use this to enforce only one resize per group of actions, which can help performance.

I am saying review+ here, but I don’t think this merits adding WKViewPrivate.

This is no more SPI than any other aspect of WebKit2. I suggest not using the term SPI.

>> +@interface WKView (Private)

This is a bug in the style queue.

> Source/WebKit2/UIProcess/API/mac/WKViewPrivate.h:34
> +// Stops updating the size of the page as the WKView frame size updates.
> +// This should always be followed by enableFrameSizeUpdates. Calls can be nested.
> +- (void)disableFrameSizeUpdates;
> +// Immediately updates the size of the page to match WKView's frame size
> +// and allows subsequent updates as the frame size is set. Calls can be nested.
> +- (void)enableFrameSizeUpdates;
> +- (BOOL)frameSizeUpdatesDisabled;

I don’t think these need to be in a separate private header. Why wouldn’t we make these public for any client of WKView?

I talked to Anders about making it API, but he preferred to keep it SPI in case we wanted to change it later, since this was created to solve a specific problem that may or may not remain.
