## Member Function Documentation

void VideoDriver_Win32::AcquireBlitterLock | ( |  | ) |
| virtual

Acquire any lock(s) required to be held when changing blitters.

These lock(s) may not be acquired recursively.

Reimplemented from VideoDriver.

Definition at line 1340 of file win32_v.cpp.

References ThreadMutex::BeginCritical().

bool VideoDriver_Win32::AfterBlitterChange | ( |  | ) |
| virtual

Callback invoked after the blitter was changed.

This may only be called between AcquireBlitterLock and ReleaseBlitterLock.

Returns
  True if no error.

Reimplemented from VideoDriver.

Definition at line 1335 of file win32_v.cpp.

References MakeWindow().

bool VideoDriver_Win32::ChangeResolution | ( | int | w,
|  | int | h
| ) |  |
| virtual

Change the resolution of the window.

Parameters

  w | The new width.
  h | The new height.

Returns
  True if the change succeeded.

Implements VideoDriver.

void VideoDriver_Win32::EditBoxLostFocus | ( |  | ) |
| virtual

An edit box lost the input focus.

Abort character compositing if necessary.

Reimplemented from VideoDriver.

Definition at line 1350 of file win32_v.cpp.

const char* VideoDriver_Win32::GetName | ( |  | ) | const
| inline virtual

Get the name of this driver.

Returns
  The name of the driver.

Implements Driver.

Definition at line 42 of file win32_v.h.

void VideoDriver_Win32::MakeDirty | ( | int | left,
|  | int | top,
|  | int | width,
|  | int | height
| ) |  |
| virtual

Mark a particular area dirty.

Parameters

  left | The left most line of the dirty area.
  top | The top most line of the dirty area.
  width | The width of the dirty area.
  height | The height of the dirty area.

Implements VideoDriver.

Definition at line 1171 of file win32_v.cpp.

bool VideoDriver_Win32::MakeWindow | ( | bool | full_screen | ) |

Instantiate a new window.

Parameters

  full_screen | Whether to make a full screen window or not.

Returns
  True if the window could be created.
