Synopsis #

Header: fxcg/keyboard.h
Syscall index: 0x121D
Function signature: void DisplayMBString(unsigned char *buffer, int start, int cursor, int x, int y)

Draws a multi-byte string for manual single-line text editing. A blinking cursor is provided and the string does not wrap.

Parameters #

• buffer - A multi-byte (i.e., supports special characters) text string that will be displayed, can be constant.
• start - Location of the first character to display. 0 is the beginning of the string, >0 will shift the string to the left. If cursor>start then the location of the first character will be cursor.
• cursor - Location of the cursor from the start of the string. This is absolute and is from the start of the displayed text (cursor of 3 and start of 2, the cursor is located after the first character displayed, not after the third). 0 is before the first character.
• x - X location to draw the string in “homescreen” coordinates, similar to PrintXY.
• y - Y location to draw the string in “homescreen” coordinates, similar to PrintXY.

Comments #

Function is non-blocking, meant for manual string entry. String editing has to be done with other function(s) like the conjunction of EditMBStringCtrl and EditMBStringChar. Cursor blinking cannot be moved unless this function is re-called with updated cursor.

Result of setting cursor out of bounds has not been tested, overflow characters are not drawn.
