I am looking at:
function [x, y, button] = __fltk_ginput__ (f, n = -1)
I think a simple, and not toolkit specific, implementation could leverage the existence of the function waitfor. Conceptually, you can wait for a button press using something along those lines:set (gcf, 'windowbuttondownfcn', @(f) set (f, 'userdata', 1));waitfor (gcf, 'userdata');This is the core functionality. Then you need to wrap this up with:- save/restore windowbuttonfcn and userdata properties- loop to retrieve multiple mouse clicks- keep track of the pointer coordinates for each mouse click- listen for Enter key to stop the processAFAIK, "waitfor" works in both Qt and FLTK toolkits, so you'd have an implementation that works for both.Michael.What we need for sisotool is a non blocking mouse event grabber.The user , after a plot is drawn, MIGHT want to click on it or might not.I don't understand your concern. ginput also suspends octave...Michael.Is there any way to make a nonblocking mouse event function, using the uixxx type of logic?If there isn't then I don't see how we can do the sisotool using uixxx functions.
I could be made in qt c++ language but this is quit a different GSoC project.I'm assuming that many of the UI callbacks are not implemented yet?for a description of how you can register for mouse event through a callback function. This is how I normally do little GUI tools in Matlab, rather than ginput. I usually use ginput for cases where it is just a simple script with a known number of points.
