I made a callback function for an value_input field so that the beginning 0 was
to disapere when an other value was entered.
Here i noticed that if the value_input would say 01..07 it was equal to the
value 1..7. All good that far but if you enter 08 or 09 the value will still be
0 if you read it and also the callback function wont be called.
Simple example code:
#include "input_field_ex.h"
Fl_Value_Input *my_input=(Fl_Value_Input *)0;
void modify_value(Fl_Value_Input*, void*){
int a= my_input->value();
my_input->value(1);//Trick compiler to not opimize code
value(value(my_input))
my_input->value(2);// trick compiler cont.
my_input->value(a);
}
int main(int argc, char **argv) {
Fl_Double_Window* w;
{ Fl_Double_Window* o = new Fl_Double_Window(475, 268);
w = o;
{ my_input = new Fl_Value_Input(25, 25, 25, 25);
my_input->maximum(50000);
my_input->step(1);
my_input->callback((Fl_Callback*)modify_value);
} // Fl_Value_Input* my_input
o->end();
} // Fl_Double_Window* o
w->show(argc, argv);
return Fl::run();
}
Here default value is 0, enter 1 or 2 or .. 7 you will only see 7. Enter 8 or 9
you will see 08 or 09. If you make an alert in the callback function you will
see that it doesnt even get called for the last 2 cases.
