SetVideoDriver

Install a new video driver.

Declaration

Source position: videoh.inc line 196

function SetVideoDriver(

  const Driver: TVideoDriver

):Boolean;

Description

SetVideoDriver sets the videodriver to be used to Driver. If the current videodriver is initialized (after a call to InitVideo) then it does nothing and returns False.

A new driver can only be installed if the previous driver was not yet activated (i.e. before a call to InitVideo) or after it was deactivated (i.e after a call to DoneVideo).

For more information about installing a videodriver, see viddriver.

For an example, see the section on writing a custom video driver.

Errors

If the current driver is initialized, then False is returned.
