wxPython ListCtrl OnClick Event

So, I have a wxPython ListCtrl which contains rows of data. How can I make an event that calls a function, with the row contents, when one of the rows if clicked on?

You can use the Bind function to bind a method to an event. For example,

import wx

class MainWidget(wx.Frame):

    def __init__(self, parent, title):
        super(MainWidget, self).__init__(parent, title=title)

        self.list = wx.ListCtrl(parent=self)
        for i,j in enumerate('abcdef'):
            self.list.InsertStringItem(i,j)
        self.Bind(wx.EVT_LIST_ITEM_ACTIVATED, self.OnClick, self.list)

        self.Layout()

    def OnClick(self, event):
        print event.GetText()



if __name__ == '__main__':
    app = wx.App(redirect=False)
    frame = MainWidget(None, "ListCtrl Test")
    frame.Show(True)
    app.MainLoop()

This app will print the item in the ListCtrl that is activated (by pressing enter or double-clicking). If you just want to catch a single click event, you could use wx.EVT_LIST_ITEM_SELECTED.

The important point is that the Bind function specifies the method to be called when a particular event happens. See the section in the wxPython Getting Started guide on event handling. Also see the docs on ListCtrl for the events that widget uses.
