Detailed Description

Class used to represent a frame in the browser window.

When used in the browser process the methods of this class may be called on any thread unless otherwise indicated in the comments. When used in the render process the methods of this class may only be called on the main thread.

Member Function Documentation

◆ Copy()

virtual void CefFrame::Copy ( )

pure virtual

Execute copy in this frame.

◆ CreateURLRequest()

virtual CefRefPtr<CefURLRequest> CefFrame::CreateURLRequest	(	CefRefPtr< CefRequest >	request,
		CefRefPtr< CefURLRequestClient >	client
	)

pure virtual

Create a new URL request that will be treated as originating from this frame and the associated browser.

This request may be intercepted by the client via CefResourceRequestHandler or CefSchemeHandlerFactory. Use CefURLRequest::Create instead if you do not want the request to have this association, in which case it may be handled differently (see documentation on that method). Requests may originate from both the browser process and the render process.

For requests originating from the browser process:

POST data may only contain a single element of type PDE_TYPE_FILE or PDE_TYPE_BYTES.

For requests originating from the render process:

POST data may only contain a single element of type PDE_TYPE_BYTES.
If the response contains Content-Disposition or Mime-Type header values that would not normally be rendered then the response may receive special handling inside the browser (for example, via the file download code path instead of the URL request code path).

The |request| object will be marked as read-only after calling this method.

◆ Cut()

virtual void CefFrame::Cut ( )

pure virtual

Execute cut in this frame.

◆ Delete()

virtual void CefFrame::Delete ( )

pure virtual

Execute delete in this frame.

◆ ExecuteJavaScript()

virtual void CefFrame::ExecuteJavaScript	(	const CefString &	code,
		const CefString &	script_url,
		int	start_line
	)

pure virtual

Execute a string of JavaScript code in this frame.

The |script_url| parameter is the URL where the script in question can be found, if any. The renderer may request this URL to show the developer the source of the error. The |start_line| parameter is the base line number to use for error reporting.

◆ GetBrowser()

virtual CefRefPtr<CefBrowser> CefFrame::GetBrowser ( )

pure virtual

Returns the browser that this frame belongs to.

◆ GetIdentifier()

virtual int64 CefFrame::GetIdentifier ( )

pure virtual

Returns the globally unique identifier for this frame or < 0 if the underlying frame does not yet exist.

◆ GetName()

virtual CefString CefFrame::GetName ( )

pure virtual

Returns the name for this frame.

If the frame has an assigned name (for example, set via the iframe "name" attribute) then that value will be returned. Otherwise a unique name will be constructed based on the frame parent hierarchy. The main (top-level) frame will always have an empty name value.

◆ GetParent()

virtual CefRefPtr<CefFrame> CefFrame::GetParent ( )

pure virtual

Returns the parent of this frame or NULL if this is the main (top-level) frame.

◆ GetSource()

virtual void CefFrame::GetSource ( CefRefPtr< CefStringVisitor > visitor )

pure virtual

Retrieve this frame's HTML source as a string sent to the specified visitor.

◆ GetText()

virtual void CefFrame::GetText ( CefRefPtr< CefStringVisitor > visitor )

pure virtual

Retrieve this frame's display text as a string sent to the specified visitor.

◆ GetURL()

virtual CefString CefFrame::GetURL ( )

pure virtual

Returns the URL currently loaded in this frame.

◆ GetV8Context()

virtual CefRefPtr<CefV8Context> CefFrame::GetV8Context ( )

pure virtual

Get the V8 context associated with the frame.

This method can only be called from the render process.

◆ IsFocused()

virtual bool CefFrame::IsFocused ( )

pure virtual

Returns true if this is the focused frame.

◆ IsMain()

virtual bool CefFrame::IsMain ( )

pure virtual

Returns true if this is the main (top-level) frame.

◆ IsValid()

virtual bool CefFrame::IsValid ( )

pure virtual

True if this object is currently attached to a valid frame.

◆ LoadRequest()

virtual void CefFrame::LoadRequest ( CefRefPtr< CefRequest > request )

pure virtual

Load the request represented by the |request| object.

WARNING: This method will fail with "bad IPC message" reason INVALID_INITIATOR_ORIGIN (213) unless you first navigate to the request origin using some other mechanism (LoadURL, link click, etc).

◆ LoadURL()

virtual void CefFrame::LoadURL ( const CefString & url )

pure virtual

Load the specified |url|.

◆ Paste()

virtual void CefFrame::Paste ( )

pure virtual

Execute paste in this frame.

◆ Redo()

virtual void CefFrame::Redo ( )

pure virtual

Execute redo in this frame.

◆ SelectAll()

virtual void CefFrame::SelectAll ( )

pure virtual

Execute select all in this frame.

◆ SendProcessMessage()

virtual void CefFrame::SendProcessMessage	(	CefProcessId	target_process,
		CefRefPtr< CefProcessMessage >	message
	)

pure virtual

Send a message to the specified |target_process|.

Ownership of the message contents will be transferred and the |message| reference will be invalidated. Message delivery is not guaranteed in all cases (for example, if the browser is closing, navigating, or if the target process crashes). Send an ACK message back from the target process if confirmation is required.

◆ Undo()

virtual void CefFrame::Undo ( )

pure virtual

Execute undo in this frame.

◆ ViewSource()

virtual void CefFrame::ViewSource ( )

pure virtual

Save this frame's HTML source to a temporary file and open it in the default text viewing application.

This method can only be called from the browser process.

◆ VisitDOM()

virtual void CefFrame::VisitDOM ( CefRefPtr< CefDOMVisitor > visitor )

pure virtual

Visit the DOM document.

This method can only be called from the render process.
