One thing that drives me mad on fluid sometimes is to fine adjust
placement/size of widgets, with the left mouse button it is supposed to
increment/decrement at 1 steps but most of the time it
increments/decrements in ore than 1 step.
With the modification bellow to the Fl_Value_Input::handle if we press
CTRL key it is more likely to increment/decrement a 1 step.
--------------------------------
int Fl_Value_Input::handle(int event) {
...
case FL_DRAG:
if (!step()) goto DEFAULT;
delta = mx-ix;
if(Fl::event_ctrl()) { //new code
delta /= 5; //new code
} else { //new code
if (delta > 5) delta -= 5;
else if (delta < -5) delta += 5;
else delta = 0;
} //new code
switch (drag) {
case 3: v = increment(previous_value(), delta*100); break;
case 2: v = increment(previous_value(), delta*10); break;
default:v = increment(previous_value(), delta); break;
}
v = round(v);
