void cCursesOsd::DrawRectangle ( int  x1,
int  y1,
int  x2,
int  y2,
tColor  Color 
) [virtual]

Draws a filled rectangle defined by the upper left (x1, y1) and lower right (x2, y2) corners with the given Color.

Reimplemented from cOsd.

void cCursesOsd::DrawText ( int  x,
int  y,
const char *  s,
tColor  ColorFg,
tColor  ColorBg,
const cFont Font,
int  Width = 0,
int  Height = 0,
int  Alignment = taDefault 
) [virtual]

Draws the given string at coordinates (x, y) with the given foreground and background color and font.

If Width and Height are given, the text will be drawn into a rectangle with the given size and the given Alignment (default is top-left). If ColorBg is clrTransparent, no background pixels will be drawn, which allows drawing "transparent" text.

Reimplemented from cOsd.

void cCursesOsd::Flush ( void  ) [virtual]

Actually commits all data to the OSD hardware.

Flush() should return as soon as possible. For a true color OSD using the default implementation with in memory pixmaps, the Flush() function should basically do something like this:

LOCK_PIXMAPS; while (cPixmapMemory *pm = RenderPixmaps()) { int w = pm->ViewPort().Width(); int h = pm->ViewPort().Height(); int d = w * sizeof(tColor); MyOsdDrawPixmap(Left() + pm->ViewPort().X(), Top() + pm->ViewPort().Y(), pm->Data(), w, h, h * d); delete pm; }

void cCursesOsd::RestoreRegion ( void  ) [virtual]

Restores the region previously saved by a call to SaveRegion().

If SaveRegion() has not been called before, nothing will happen.

Reimplemented from cOsd.

Definition at line 126 of file skincurses.c.

References savedRegion, and window.

void cCursesOsd::SaveRegion ( int  x1,
int  y1,
int  x2,
int  y2 
) [virtual]

Saves the region defined by the given coordinates for later restoration through RestoreRegion().

Only one saved region can be active at any given time.
