[issue29559] Detect mouse over lines on canvas while mouse button is down
New submission from Ted Shaneyfelt: There way mouse captures are done, mouse-over events seem to be disabled while dragging. This makes it difficult to provides hints as feedback, and more complicated than it should be to detect when dropping over a particular line object. Tk may not directly support it, but is there any way of getting into its guts to provide an option to re-enable mouse-over events while dragging? Or even providing a tuple with the pending mouse-overs upon release? or perhaps even simulate a mouse-up-mouse-down sequence to allow the events to propagate through and consume the noise within tkinter? Or even detect that there is a pending mouseover waiting for the mouseup event and delivering it along with the mouseup or notifying within the event that there is one pending? -- components: Tkinter messages: 287789 nosy: Ted Shaneyfelt2 priority: normal severity: normal status: open title: Detect mouse over lines on canvas while mouse button is down type: enhancement versions: Python 3.6 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29559> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue29467] Allow return mismatch to be caught by function
New submission from Ted Shaneyfelt: def f(): try: return 0 except: return 1,2 x = f() # x is 0 x,y = f() # proposal: x,y should be 1,2 instead of uncaught TypeError It would make sense to be able to catch [TypeError: 'int' object is not iterable] and return the correct number of values. Yes, the way it's done now, the function is no longer running when it is caught - but is it possible and practical to determine if parameters match before the function returns instead of afterward, allowing the called function to catch the error attempting to return? -- components: Interpreter Core messages: 287173 nosy: Ted Shaneyfelt priority: normal severity: normal status: open title: Allow return mismatch to be caught by function type: enhancement versions: Python 3.5 ___ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29467> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
