This week, I needed to figure out how to attach an event handler that would fire when I double-clicked an item (i.e. row) in an ObjectListView widget that was in LC_REPORT mode. For some reason, there isn’t an obvious mouse event for that. There is an EVT_LIST_ITEM_RIGHT_CLICK and an EVT_LIST_ITEM_MIDDLE_CLICK, but nothing for LEFT clicks of any sort. After a bit of searching on Google, I found that I can get it to work by using EVT_LIST_ITEM_ACTIVATED. This will fire when an item is double-clicked and when an item is selected and the user presses ENTER. Here’s a code example:
import wx
from ObjectListView import ObjectListView, ColumnDefn
########################################################################
class Results(object):
""""""
#----------------------------------------------------------------------
def __init__(self, tin, zip_code, plus4, name, address):
"""Constructor"""
self.tin = tin
self.zip_code = zip_code
self.plus4 = plus4
self.name = name
self.address = address
########################################################################
class DCPanel(wx.Panel):
""""""
#----------------------------------------------------------------------
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent=parent)
mainSizer = wx.BoxSizer(wx.VERTICAL)
self.test_data = [Results("123456789", "50158", "0065", "Patti Jones",
"111 Centennial Drive"),
Results("978561236", "90056", "7890", "Brian Wilson",
"555 Torque Maui"),
Results("456897852", "70014", "6545", "Mike Love",
"304 Cali Bvld")
]
self.resultsOlv = ObjectListView(self, style=wx.LC_REPORT|wx.SUNKEN_BORDER)
self.resultsOlv.Bind(wx.EVT_LIST_ITEM_ACTIVATED, self.onDoubleClick)
self.setResults()
mainSizer.Add(self.resultsOlv, 1, wx.EXPAND|wx.ALL, 5)
self.SetSizer(mainSizer)
#----------------------------------------------------------------------
def onDoubleClick(self, event):
"""
When the item is double-clicked or "activated", do something
"""
print "in onDoubleClick method"
#----------------------------------------------------------------------
def setResults(self):
""""""
self.resultsOlv.SetColumns([
ColumnDefn("TIN", "left", 100, "tin"),
ColumnDefn("Zip", "left", 75, "zip_code"),
ColumnDefn("+4", "left", 50, "plus4"),
ColumnDefn("Name", "left", 150, "name"),
ColumnDefn("Address", "left", 200, "address")
])
self.resultsOlv.CreateCheckStateColumn()
self.resultsOlv.SetObjects(self.test_data)
########################################################################
class DCFrame(wx.Frame):
""""""
#----------------------------------------------------------------------
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, parent=None, title="Double-click Tutorial")
panel = DCPanel(self)
#----------------------------------------------------------------------
if __name__ == "__main__":
app = wx.App(False)
frame = DCFrame()
frame.Show()
app.MainLoop()
Pretty straight-forward, right? I hope it’ll help you if you ever need to know how to do this. This method should work with a ListCtrl as well.
