Detailed Description
A common base class for Text displays.
Definition at line 23 of file TextDisplay.h.
Constructor & Destructor Documentation
| TextDisplay | ( | const char * | name = NULL ) |
Create a TextDisplay interface.
- Parameters:
-
name The name used in the path to access the strean through the filesystem
Definition at line 8 of file TextDisplay.cpp.
Member Function Documentation
| void background | ( | uint16_t | colour ) | [virtual] |
set the background color
- Note:
- this method may be overridden in a derived class.
- Parameters:
-
color is color to use for background drawing.
Definition at line 61 of file TextDisplay.cpp.
| virtual void character | ( | int | column, |
| int | row, | ||
| int | c | ||
| ) | [pure virtual] |
output a character at the given position
- Parameters:
-
column column where charater must be written row where character must be written c the character to be written to the TextDisplay
- Note:
- this method may be overridden in a derived class.
Implemented in GraphicsDisplay.
| bool claim | ( | FILE * | stream ) | [virtual] |
redirect output from a stream (stoud, sterr) to display
- Parameters:
-
stream stream that shall be redirected to the TextDisplay
- Note:
- this method may be overridden in a derived class.
- Returns:
- true if the claim succeeded.
Definition at line 65 of file TextDisplay.cpp.
