Member Function Documentation

void cDvbOsd::CloseWindow (  cWindow *    Window )  [protected, virtual]

Close the window and release any OSD hardware resources allocated for it. Implements cOsdBase. Definition at line 121 of file dvbosd.c. References Cmd(), and SetWindow(). Referenced by ~cDvbOsd().

void cDvbOsd::Cmd (  OSD_Command    cmd, int    color = 0, int    x0 = 0, int    y0 = 0, int    x1 = 0, int    y1 = 0, const void *    data = NULL )  [private]

Definition at line 52 of file dvbosd.c. References osdDev. Referenced by CloseWindow(), CommitWindow(), HideWindow(), MoveWindow(), OpenWindow(), SetWindow(), and ShowWindow().

void cDvbOsd::CommitWindow (  cWindow *    Window )  [protected, virtual]

Write any modified data and color definitions to the OSD hardware. Use the window's Dirty() function to find out which area of data actually needs to be transferred. If the window has not yet been explicitly shown through a call to ShowWindow(), no visible activity shall take place. Implements cOsdBase. Definition at line 87 of file dvbosd.c. References Cmd(), cWindow::Data(), cBitmap::Dirty(), eDvbColor, cPalette::NewColors(), SetWindow(), and cBitmap::Width().

void cDvbOsd::HideWindow (  cWindow *    Window, bool    Hide )  [protected, virtual]

Temporarily hide the window (if 'Hide' is 'true') or make a previously hidden window visible again (if 'Hide' is 'false'). Implements cOsdBase. Definition at line 109 of file dvbosd.c. References Cmd(), and SetWindow().

void cDvbOsd::MoveWindow (  cWindow *    Window, int    x, int    y )  [protected, virtual]

Move the window to a new location. Implements cOsdBase. Definition at line 115 of file dvbosd.c. References Cmd(), SetWindow(), cOsdBase::X0(), and cOsdBase::Y0().

bool cDvbOsd::OpenWindow (  cWindow *    Window )  [protected, virtual]

Opens the window on the OSD hardware, without actually showing it (the initial state shall be "hidden"). Implements cOsdBase. Definition at line 78 of file dvbosd.c. References cWindow::Bpp(), Cmd(), cBitmap::Height(), SetWindow(), cBitmap::Width(), cWindow::X0(), cOsdBase::X0(), cWindow::Y0(), and cOsdBase::Y0().

void cDvbOsd::SetDvbDevice (  const cDvbDevice *    DvbDevice )  [static]

Definition at line 32 of file dvbosd.c. References dvbDevice. Referenced by cDvbDevice::MakePrimaryDevice().

bool cDvbOsd::SetWindow (  cWindow *    Window )  [private]

Definition at line 37 of file dvbosd.c. References Cmd(), esyslog, cWindow::Handle(), and MAXNUMWINDOWS. Referenced by CloseWindow(), CommitWindow(), HideWindow(), MoveWindow(), OpenWindow(), and ShowWindow().

void cDvbOsd::ShowWindow (  cWindow *    Window )  [protected, virtual]

Make the window actually visible on the OSD hardware. Implements cOsdBase. Definition at line 103 of file dvbosd.c. References Cmd(), SetWindow(), cWindow::X0(), cOsdBase::X0(), cWindow::Y0(), and cOsdBase::Y0().
