| virtual void character | ( | int | column, |
| int | row, | ||
| int | c | ||
| ) | [pure virtual, inherited] |
writes a character to the specified position must be public because it is used during delegation
- Parameters:
-
column The horizontal position from the left, indexed from 0 row The vertical position from the top, indexed from 0 c the character
Implemented in DogmLCDSPI, HD44780LCD8bit, KS0108LCD8bit, MultiWindow, SED1335TextLCD, SubWindow, TeeWindow, Terminal, and TextLCDAdapter.

| void locate | ( | int | column, |
| int | row | ||
| ) | [virtual, inherited] |
set (internal) cursor to a screen column and row
- Parameters:
-
column The horizontal position from the left, indexed from 0 row The vertical position from the top, indexed from 0

| int printf | ( | const char * | format, |
| ... | |||
| ) | [inherited] |
Write a formated string to the LCD, on the position specified by the cursor does wrap around (as specified by putc)
- Parameters:
-
format A printf-style format string, followed by the variables to use in formating the string.
Reimplemented in TextLCDAdapter.
| int putc | ( | int | c ) | [inherited] |
Write a character to the LCD, on the position specified by the cursor sets the cursor to the next position, and wraps (from right to left, next line, and from bottom back to top)
- Parameters:
-
c The character to write to the display
Reimplemented in TextLCDAdapter.
| virtual void writeText | ( | const unsigned int | column, |
| const unsigned int | row, | ||
| const char | text[] | ||
| ) | [pure virtual, inherited] |
write text into the window, at the given position.
this doesn't change the internal cursor position Implementations should check for the length of the text and shorten it accordingly. columns the column where to write row the line where to write text the text to write
