Function fltk::app::keyboard_screen_scaling

pub fn keyboard_screen_scaling(value: bool)

Controls the possibility to scale all windows by ctrl/+/-/0/ or cmd/+/-/0/

This function should be called before app::open_display runs. If it is not called, the default is to handle these keys for window scaling.

Pass a value of false to stop recognition of ctrl/+/-/0/ (or cmd/+/-/0/ under macOS) keys as window scaling.
