Bug 57909 – REGRESSION: Drag & Drop Gmail Attachments doesn't work

• Status: RESOLVED
• Resolution: FIXED
• Component: WebKit2

[Enrica Casucci]

* STEPS TO REPRODUCE:
1) Open Gmail in Safari
2) Compose a message
3) Drag a file from Finder to the Safari window.

* EXPECTED RESULTS:
The formatting bar should change to 'Drop Files' box and dropping the file should attach it to the message and upload it. 

* ACTUAL RESULTS:
Nothing. The formatting bar doesn't change to the 'Drop Files' box, and if you do drop the file, Safari opens it in the current tab instead of attaching it to the message.

r=me as is, but you’ll probably have to merge with my change to this file and you may want to consider changes based on the comments

> Source/WebCore/platform/DragData.h:121
> +    NSPasteboard* pasteboard() { return m_pasteboard.get(); }

We’re supposed to format Objective-C type pointer expressions as “NSPasteboard *” rather than “NSPasteboard*”.

> Source/WebKit2/UIProcess/API/mac/WKView.mm:85
> +@interface NSView (WebNSViewDetails)

The right prefix to use in WebKit2 is WK rather than Web, so this should be WKNSViewDetails.

> Source/WebKit2/UIProcess/API/mac/WKView.mm:1458
> +// This code is needed to support drag and drop. AppKit calls _hitTest on all the views in the application

I don’t understand what you mean by “on all views in the application” here. I think the comment should say that we need to override this to allow us to support drags of all types without declaring all the types in advance. Unless that’s not the reason.

> Source/WebKit2/UIProcess/API/mac/WKView.mm:1464
> +    NSView *hitView = [super _hitTest:point dragTypes:types];
> +    if (!hitView && [[self superview] mouse:*point inRect:[self frame]])

> +    return hitView;

I think we could instead just say:

    if ([[self superview] mouse:*point inRect:[self frame]])
        return self;
    return nil;

Then we would not need to declare the WebNSViewDetails category above.
