C# 클래스 TransvoxelXnaStudio.Host.GraphicsDeviceControl

Disposes the control.

Derived classes override this to draw themselves using the GraphicsDevice.

Ends drawing the control. This is called after derived classes have finished their Draw method, and is responsible for presenting the finished image onto the screen, using the appropriate WinForms control handle to make sure it shows up in the right place.

Derived classes override this to initialize their drawing code.

Initializes the control.

Redraws the control in response to a WinForms paint message.

Ignores WinForms paint-background messages. The default implementation would clear the control to the current background color, causing flickering when our OnPaint implementation then immediately draws some other color over the top using the XNA Framework GraphicsDevice.

If we do not have a valid graphics device (for instance if the device is lost, or if we are running inside the Form designer), we must use regular System.Drawing method to display a status message.

Attempts to begin drawing the control. Returns an error message string if this was not possible, which can happen if the graphics device is lost, or if we are running inside the Form designer.

Helper used by BeginDraw. This checks the graphics device status, making sure it is big enough for drawing the current control, and that the device is not lost. Returns an error string if the device could not be reset.
