Hi,
I'm using fltk2-6844. I had created a class that is derived from fltk::Button.
This class should store additional type information in Widget::type() as
described in the docs: "Widget subclasses may store values in the range 0-99
here (larger values are reserved for use by FLTK)". But when I store and value
in this area the button works always as a toggle button.
Looking in the FLTK source code I've found the problem: The button state is
always checked like this:
if (type() == RADIO) {
...
} else if (type()) { // TOGGLE
...
} else {
...
}
So any type unequal zero or unequal RADIO will force a toggle button. If the
toggle button is explicit checked like the radio button (e.g. if (type() ==
TOGGLE)) this will force any subclass type to a normal push button which is
also not desired. I think the best way will be only to check the reserved bits
of the type variable like this.
if (type() & RADIO) {
...
} else if (type() & TOGGLE {
...
} else {
...
}
This will make it possible to use the free range of the type variable in
subclasses.
