This subject came up on the DaniWeb Python discussion board, and I was curious about it:
(http://www.daniweb.com/techtalkforums/thread70746.html) The issue is an apparent difference between PCs and Macs in interpreting key holds. The following code: --- from Tkinter import * class MyFrame(Frame): def __init__(self, master): Frame.__init__(self, master) self.go = False self.bind('<a>', self.showJudgments) self.bind('<KeyRelease-a>', self.makeChoice) self.pack(expand=YES, fill=BOTH) self.focus_force() def showJudgments(self, event=None): if self.go == False: self.go = True self.showJudgmentsA() else: self.keepShowing() def keepShowing(self): print 'a key being pressed' def showJudgmentsA(self): print "key-press started" def makeChoice(self, event=None): print "choice made" self.go = False mainw = Tk() mainw.f = MyFrame(mainw) mainw.f.grid() mainw.mainloop() --- on a PC produces this output: --- key-press started # pressed 'a' here a key being pressed a key being pressed ... a key being pressed choice made # let go here --- and on a Mac, this output: --- key-press started choice made key-press started choice made key-press started choice made key-press started choice made --- Apparently, Macs interpret held keys as press/release, press/release, ... Is this correct? Thanks, Jeff _______________________________________________ Tkinter-discuss mailing list [email protected] http://mail.python.org/mailman/listinfo/tkinter-discuss
