ShowDialog

void OSD::ShowDialog ( const MythOSDDialogData &  Data )

protectedslot

Show a dialog menu, removing any existing dialog.

This slot deliberately uses a const reference despite the minor performance penalty. This simplifies memory management (e.g. if the signal is not delivered when there is no OSD) and allows for possible future changes where the OSD and TV objects do not reside in the same thread.
