Hi there, I have derived my own class cMenuEditIpNumItem from cMenuEditItem. It displays 4 segments, seperated by dots.
My Problem is _SOMETIMES_ if kOk is pressed, the item remains in insert mode. If so, pressing kLeft, kRight release this behaviour.
Explanation: Edit mode are indicated with brakets:
"My IP Address 192.[168].10.3
int pos segment counter, range 0-4, greater than 0 means edit mode int digit digit of actual segment. unsinged char val[5] container for IP values. actuall 4 segments 1-4 are used. val[0] is not used. --- unsinged char will be used as unsigned int 0 -255.
char *value the actuall string displayed in menu item.
I have no Idea where the Problem coud be. Of course, the "ProccesKey"-Funktion gets the correct key code.
for the hole class see attachment.
