Error catching in wx.html2 window 
  I'm using a wx.html2 (wx2.9) window to show an HTML help file. This works fine, but I can't figure out how to catch any errors. It's possible that the user might get a site-down or 404 error. Is there a way to catch these errors? (Or any more detailed information on the new html2 control?) In the attached code, I'd hoped OnError would be called and would raise an... more »

Mac-noob advice for installing 
  I'm helping a friend at a distance set up a Python/wxPython (and other libraries) environment on his Mac (OSX Lion)...he was able to get wxPython to work using the Mac-installed version of Python but it might be balking now for Matplotlib, so I'm going to suggest he install the Python.org version of Python 2.7.3 and try again.... more »

Select() for ListCtrl not same as mouse-click-select? 
  I have a ListCtrl (REPORT_MODE and SINGLE_SEL). The user can click in this to highlight an entry in it and it appears reversed. There are times where I want to change the selected entry programmatically. I can do this with: across_clues.Focus(idx) across_clues.Select(idx) (the Focus() makes sure the selected item is currently scrolled to; the... more »

Interrupting computation 
  Guys, I know this is a topic for the Python list, not the wxPython, but you guys are so ressourceful that I dare submitting my problem to you. As in most of the software, an 'Cancel computation' button is required and I have trouble to make it work clean. Here is how my application works. The Cancel computation button is, of... more »

TwoStageCreation Initialization 
  Hello, I'm trying to add a custom listcontrol to an XRC dialog following the TwoStageCreation <[link]> description in the wiki. As suggested in the example, I am adding columns to my control in the wx.EVT_WINDOW_CREATE handler. However, I don't understand at which point I can safely use the created... more »

Mouse middle button has strange effect in grids 
  The middle button seems to have a strange effect in grids. In particular, if I hold it down it creates a visual selection of cells, like a range selection, but that does not trigger a EVT_GRID_RANGE_SELECT event. What I would like to do is that my grid completely ignores all click events on the middle button. I have tried to catch EVT_MIDDLE_DOWN, EVT_MIDDLE_UP,... more »

Momentary button 
  Am I right in thinking that wxButton cannot bind in a momentary fashion, ie trigger an event when the mouse button is pressed (on the button), and another when it is released? I have tried to bind it using wx.EVT_LEFT_DOWN, but the event is not triggered. I get the feeling that the only event that can be detected is that the mouse button has... more »

Setting Focus to Grid when Clicking on Grid Label 
  Hi wxPython users: I'm not sure if this is a feature, or a bug. I have a Grid control and TextCtrl on the same panel. I expect the focus to shift to the Grid control when the user clicks on a row or column label, but it does not. Keyboard operations are still directed to the last active control, which is a... more »

dc.DrawText performance issues 
  I'm drawing a network graph with wx.PaintDC. For each link in my graph I draw the source and destination port numbers on a box over the link 30pixels away from the endpoints. This works fine when I'm only drawing the ports for a single link, but when I draw the ports for all of the links (I'm testing on tree with 12 links) I get a major... more »
