问题 I have written a Python Add-In for ArcGIS program ArcMap that uses the wxPython package to generate a wx.Frame window with multiple controls, including an Exit button that closes the window.

However, after a variable number of times running the Add-in, I get a fatal error on running the Add-In again. (Sometimes it fails the second time I run it. Sometimes I can run it

问题 I want to add spreadsheet functionality to my wxpython application running on Windows. The CSheet module seems broken in the latest 2.9 version. It shows: TypeError: EndEdit() takes exactly 4 arguments (5 given) May I know if there is any suggestions to fix it or any other python module with good spreadsheet functionality ?

问题 In Mozilla Thunderbird mail you can assing items in a list a colour. The "focus selector" usually has the "cursor colour" that is defined by the window theme on your OS. Now, when you select a coloured item in Thunderbird, the focus cursor changes colour accordingly. That is to indicate that this item has a colour.

问题 I have a section of code which returns events generated by a slider. I bind the event with self.Bind(wx.EVT_SCROLL,self.OnSlide) . The code which handles the event reads something like: def OnSlide(self,event): widget = event.GetEventObject() This is great but an error gets thrown every time the code is executed. It reads: AttributeError: 'PyEventBinder' object has no attribute 'GetEventObject' I want to be able to see which of the sliders generated the event but the error appears every time

问题 I want to have a repeatable and isolated install for a wxpython project on linux , so i thought that using virtualenv + buildout would be the way to go. Is there a buildout recipe available for this? The link install wxpython in buildout seems to be gone :( 回答1: That link works for me. Maybe it was just down temporarily. 来源： https://stackoverflow.com/questions/5415930/install-wxpython-using-buildout-and-virtualenv
