| I wanted a slider that would only have odd integer values (for setting a gaussian kernel size). I set minimum=3 and maximum=11, step=2, linesize=2. But when using it, the values were even (multiples of step).
This can be changed by modifying handle_drag() in Valuator.cxx as follows:
Current:
void Valuator::handle_drag(double v) {
// round to nearest multiple of step:
if (step_ >= 1) {
v = rint(v/step_)*step_;
Modified:
void Valuator::handle_drag(double v) {
// round to nearest multiple of step:
if (step_ >= 1) {
v = rint((v-minimum_)/step_)*step_ + minimum_;
This way both even & odd work.
Cheers,
Barry | |
