Get/set the size of the Chromium viewport, in pixels. This also changes the size of the next rendered bitmap.

Create the underlying browser. The instance address, browser settings and request context will be used.

Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Releases unmanaged and - optionally - managed resources.

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

Called to retrieve the translation from view coordinates to actual screen coordinates.

Gets the Type of the current instance.

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.

Starts dragging.

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).

Occurs when [browser initialized]. 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.

Event handler for receiving Javascript console messages being sent from web pages.

(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. 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.

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'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.

Event handler that will get called when the resource load for a navigation fails or is canceled. 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.

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. 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.

Fired on the CEF UI thread, which by default is not the same as your application main thread. Called when an element should be painted. Pixel values passed to this method are scaled relative to view coordinates based on the value of ScreenInfo.DeviceScaleFactor returned from GetScreenInfo. |type| indicates whether the element is the view or the popup widget. |buffer| contains the pixel data for the whole image. |dirtyRects| contains the set of rectangles in pixel coordinates that need to be repainted. |buffer| will be |width|*|height|*4 bytes in size and represents a BGRA image with an upper-left origin.

Event handler for changes to the status message. 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).

Occurs when [title 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.
