Ahoy, ChucKists - I've just coded myself a perfectly serviceable metronome, and it works fine except for a small nagging thing in the MAUI. In my metronome, I have 2 toggle type buttons, "thirds" and "sixteenths". If one is on, the other is off, so i'm always subdividing the pulse one way or the other. As it is, if I turn "thirds" on and off, the "sixteenth" button dutifully goes off and on in a complementary way. If I do this, though: - toggle "thirds" on ("quarters" stays off) - toggle "quarters" on ("thirds" politely turns off) - toggle "thirds" on At this point they're *both* on. I can get back to a one-or-the- other state by fussing around and toggling the right combo of things, but i'd rather not do that. I've attached just the button-related code below - i've got two functions set up that are turning the other button on or off depending on whether or not they're off or on. It's bending my brain a bit to figure out why it sometimes behaves the way it does - any insights out there? thanks, as always, j. ------code------ MAUI_View view; view.size(400,200); MAUI_Button thirds; thirds.toggleType(); thirds.size(110,110); thirds.position(0, 100); thirds.name("thirds"); view.addElement(thirds); MAUI_Button sixteenths; sixteenths.toggleType(); sixteenths.size(110,110); sixteenths.position(110, 100); sixteenths.name("sixteenths"); view.addElement(sixteenths); view.display(); fun void controlThirds() { while (true) { thirds => now; sixteenths.state(0); <<<"thirds on">>>; thirds => now; sixteenths.state(1); <<<"thirds off">>>; } } fun void controlSixteenths() { while (true) { sixteenths => now; thirds.state(0); <<<"sixteenths on">>>; sixteenths => now; thirds.state(1); <<<"sixteenths off">>>; } } spork ~ controlThirds(); spork ~ controlSixteenths(); while (true) { 1::second => now; }
