DefaultRenderHandler Class

Create a new instance of DefaultRenderHadler

Contains the last bitmap buffer. Direct access to the underlying buffer - there is no locking when trying to access directly, use BitmapLock where appropriate.

The popup Bitmap.

Gets or sets a value indicating whether the popup is open.

Gets the popup position.

Gets the size of the popup.

Dispose of this instance.

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

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Serves as the default hash function.

Called to allow the client to return a ScreenInfo object with appropriate values. If null is returned then the rectangle from GetViewRect will be used. If the rectangle is still empty or invalid popups may not be drawn correctly.

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

Gets the Type of the current instance.

Called to retrieve the view rectangle which is relative to screen coordinates. This method must always provide a non-empty rectangle.

Creates a shallow copy of the current Object.

Called when an element has been rendered to the shared texture handle. This method is only called when SharedTextureEnabled is set to true

Called when the browser's cursor has changed.

Called when the IME composition range has changed.

Called when an element should be painted. Pixel values passed to this method are scaled relative to view coordinates based on the value of DeviceScaleFactor returned from GetScreenInfo. This method is only called when SharedTextureEnabled is set to false. Called on the CEF UI Thread

Called when the browser wants to show or hide the popup widget.

Called when the browser wants to move or resize the popup widget.

Called when an on-screen keyboard should be shown or hidden for the specified browser.

Called when the user starts dragging content in the web view. Contextual information about the dragged content is supplied by dragData. OS APIs that run a system message loop may be used within the StartDragging call. Don't call any of the IBrowserHost.DragSource*Ended* methods after returning false. Return true to handle the drag operation. Call DragSourceEndedAt(Int32, Int32, DragOperationsMask) and DragSourceSystemDragEnded either synchronously or asynchronously to inform the web view that the drag operation has ended.

Returns a string that represents the current object.

Called when the web view wants to update the mouse cursor during a drag & drop operation.

Need a lock because the caller may be asking for the bitmap while Chromium async rendering has returned on another thread.
