Create a new OffScreen Chromium Browser

The address (URL) which the browser control is currently displaying. Will automatically be updated as the user navigates to another page (e.g. by clicking on a link).

Contains the last rendering from Chromium. Direct access to the underlying Bitmap - there is no locking when trying to access directly, use BitmapLock where appropriate. A new bitmap is only created when it's size changes, otherwise the back buffer for the bitmap is constantly updated. Read the InvokeRenderAsync(BitmapInfo) doco for more info.

Gets or sets the bitmap factory.

Gets the browser settings.

A flag that indicates if you can execute javascript in the main frame. Flag is set to true in IRenderProcessMessageHandler.OnContextCreated. and false in IRenderProcessMessageHandler.OnContextReleased

A flag that indicates whether the state of the control current supports the GoBack action (true) or not (false).

A flag that indicates whether the state of the control currently supports the GoForward action (true) or not (false).

Determines whether the specified object is equal to the current object.

Finalizes an instance of the ChromiumWebBrowser class.

Returns the current CEF Browser Instance

Serves as the default hash function.

Gets the Type of the current instance.

Invoked from CefRenderHandler.OnPaint A new Bitmap is only created when CreateNewBitmap is true, otherwise the new buffer is simply copied into the backBuffer of the existing Bitmap for efficiency. Locking provided by OnPaint as this method is called in it's lock scope.

Loads the specified URL.

Creates a shallow copy of the current Object.

Registers a Javascript object in this specific browser instance.

Starts a task that waits for the next rendering from Chrome. Chrome also renders the page loading, so if you want to see a complete rendering, only start this task once your page is loaded (which you can detect via FrameLoadEnd or your own heuristics based on evaluating JavaScript). It is your responsibility to dispose the returned Bitmap. The bitmap size is determined by the Size property set earlier.

Immediately returns a copy of the last rendering from Chrome, or null if no rendering has occurred yet. Chrome also renders the page loading, so if you want to see a complete rendering, only start this task once your page is loaded (which you can detect via FrameLoadEnd or your own heuristics based on evaluating JavaScript). It is your responsibility to dispose the returned Bitmap. The bitmap size is determined by the Size property set earlier.

Sets the Bitmap to render with a copy of bitmap in parameter.

Returns a string that represents the current object.

Occurs when [address changed]. It's important to note this event is fired on a CEF UI thread, which by default is not the same as your application UI thread. It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread. (The exception to this is when your running with settings.MultiThreadedMessageLoop = false, then they'll be the same thread).

Event handler that will get called when the browser is done loading a frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method will always be called for all frames irrespective of whether the request completes successfully.

Event handler that will get called when the browser begins loading a frame. Multiple frames may be loading at the same time. Sub-frames may start or continue loading after the main frame load has ended. This method may not be called for a particular frame if the load request for that frame fails. For notification of overall browser load status use OnLoadingStateChange instead.

It is unwise to block on this thread for any length of time as your browser will become unresponsive and/or hang.. To access UI elements you'll need to Invoke/Dispatch onto the UI Thread.

Event handler that will get called when the Loading state has changed. This event will be fired twice. Once when loading is initiated either programmatically or by user action, and once when loading is terminated due to completion, cancellation of failure.
