Bug 27028 – [gtk] Pasteboard/GtkClipboard can't handle the "text/html" target.

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Jiahua Huang]

when I select some html content, and Copy them use Ctrl-C,
the Pasteboard/GtkClipboard can't handle the "text/html" target.

I found that the "text/html" target 
only in X clipboard (GDK_SELECTION_CLIPBOARD),
but not gtk Desktop clipboard (GDK_SELECTION_PRIMARY).

So we can't use Ctrl-C to Copy rich text from WebkitGtk.

it can use Ctrl-C to Copy rich text from WebkitGtk page now.

Maybe we can remove this altogether by grabbing the target infos via m_helper?

I think a proper fix for this is to add a function in WebKit/gtk/WebCoreSuppoer/PasteboardHelperGtk.cpp that will return the value of WEBKIT_WEB_VIEW_TARGET_INFO_HTML, and use that in clipboard_get_contents_cb.

Is there any reason for this change?

I think calling generalPasteboard() is unnecessary here.

What's this for?

Looks fine otherwise. r- for now as the patch needs to be revised.

Remove the improper set of enum WebKitWebViewTargetInfo
in platform/gtk/PasteboardGtk.cpp,
and use the enum in webkitwebview.h

This is a layering violation. WebCore should not depend on WebKit. It should go through the *Client interface, or in the case of Pasteboard, should go through PasteboardHelper. The previous patch was already doing that. Why the change?

r- because of the layering violation.

  Cound you mend it for me, please?

  Thank you very much.

The braces should be removed as there's only one statement here.

I've looked into this again and seems I overlooked a few things in my review. This patch is fine. r=me.
