Function Documentation

int GUI_edi_getModif ( MemObj mo)

GUI_edi_getModif get if buffer is modfied if buffer is modied: save; this call resets the state. returns 1=modified; 0=unmodified.

long GUI_edi_getEof ( MemObj mo)

GUI_edi_getEof get total nr of chars (not bytes)

gtk_text_buffer_get_char_count get nr of chars, not nr of bytes !

long GUI_edi_getLnMax ( MemObj mo)

GUI_edi_getLnMax get total-lines-nr

funcnam callback-function for Keypress & FocusIn-Events (none: NULL)
mode 0 = do not wrap lines; 1=yes, wrap lines
opts options; (HorSiz,VertSiz)
HorSiz,VertSiz: size in characters; default is automatic size.
negative values: size in pixels.
'e' = expand widget; default is fixed size.
Examples: "" or "10" or "10e,e"
"10e,e" horiz. size 10 chars, hor. and vert. expandable.
prototyp funcnam:
int funcnam (MemObj *mo, void **data);

Example without callback-function:

Example with callback-function:
