Hi,
This behavior is already present in the textbox when used in non-multiline
way. This is provided by the textbox_frontend.c:textbox_ignorekey()
function, right?
Then we test the following:
---------8<-----------
/* Find keys to ignore */
int textbox_ignorekey(struct widget *self, int key) {
/* Ignore some keys in single-line mode: */
if (!DATA->doc->multiline)
switch (key) {
case PGKEY_TAB:
case PGKEY_UP:
case PGKEY_DOWN:
case PGKEY_ESCAPE:
case PGKEY_RETURN:
return 1;
}
/* Ignore up key on the first line */
else if( (DATA->doc->crsr->par->prev == NULL ) && \
(DATA->doc->crsr->line->prev == NULL ) ) {
switch (key) {
case PGKEY_UP:
return 1;
}
}
/* Ignore down key on the last line */
else if( (DATA->doc->crsr->par->next == NULL ) && \
(DATA->doc->crsr->line->next == NULL ) ) {
switch (key) {
case PGKEY_DOWN:
return 1;
}
}
return 0;
}
---------8<-----------
Which give good result to enter/get out of a textbox with the up/down
keyboard keys. The behavior stay if you add chars in the textbox but if
you make a new paragraphe (hitting return) you cannot get out of the
widget any more. This certainly due to creation of a new paragraphe
Any tips?
TIA,
