wxpython listctrl

[shuf]

Hello,

I was wondering if anyone knows how to change the color of a selected item in a listctrl (for example, on my system a selected item is highlighted in blue). I could not find any information on this, other than it is a system defined parameter. Any help is greatly appreciated.

Thanks in advance,
Stephen

In your EVT_LIST_ITEM_RIGHT_CLICK handler:

item = event.GetItem()
SetItemBackgroundColour(item, colorTuple)

In your EVT_LIST_ITEM_RIGHT_CLICK handler:

item = event.GetItem()
SetItemBackgroundColour(item, colorTuple)

Of course, you'll probably want to keep the old value returned by

GetItemBackgroundColour()

around and set it back when you get an EVT_LIST_ITEM_DESELECTED event.

item = event.GetItem()
SetItemBackgroundColour(item, colorTuple)

I wanted to do the above on the EVT_LIST_ITEM_SELECTED event, so I assume that it will not be different. I bound the event to the following method:

def OnSelected(self, event):
    item = event.GetItem()
    self.listctrl.SetItemBackgroundColour(item, wx.RED)
 

But, I get an error that a number is expected for argument number 2 (item). So if I change the code to:

def OnSelected(self, event):
    item = self.listctrl.GetFirstSelected()
    self.listctrl.SetItemBackgroundColour(item, wx.RED)
 

It changes the color under the selection highlighting (I can only see the color if I deselect the item). Is there a way to change the selection highlighting color? Thanks again for your response.

Yeah, I don't see anything about setting the selected color to a different color from the default either.

Thanks for your help.

a wx.Grid has what you are looking for:

        self.grid1.SetSelectionBackground(wx.Colour(115, 247, 121))

I'm fully aware this is in old thread, but I cam across exactly the same problem and this was the only directly relevent page that came up so I thought i'd post the solution here for anyone else that has the same issue in future.

You need to bind an event handler on EVT_LIST_ITEM_SELECTED then change the item's state flags in the handler like so:

ls = wx.ListCtrl
ls.Bind(wx.EVT_LIST_ITEM_SELECTED, _item_selected)
 
def _item_selected(evt):
    i = evt.GetIndex() # Find item selected
    ls.SetItemState(i, wx.LIST_STATE_FOCUSED, wx.LIST_STATE_SELECTED) # Clear selected flag and just leave focused flag so that a box is drawn round selected item
    evt.Skip() # Let the event propogate

Thank you very much. It's always appreciated when we get this kind of contribution.
