I know I can use list_ctrl.GetStringValueAt() like so to get the value for a particular object in the ObjectListView:
class myOLV(ObjectListView):
... code to handle specific events
class myPanel(wx.Panel):
def __init__(self, parent):
wx.Panel.__init__(self, parent)
self.list_ctrl = myOLV(self, wx.ID_ANY, style=wx.LC_REPORT)
self.setColumns()
# . . .
self.submit_button = wx.Button(self, label="Submit")
# ... add to sizer here, skipping tedious stuff in this example
self.submit_button.Bind(wx.EVT_BUTTON, self.onSubmit)
def setColumns(self):
self.list_ctrl.SetColumns([
ColumnDefn("Column 1", "left", 128, "col1"),
ColumnDefn("Column 2", "left", 128, "col2"),
ColumnDefn("Column 3", "left", 128, "col3")
)]
def onSubmit(self, event):
objects = self.list_ctrl.GetObjects()
for obj in objects:
col1 = self.list_ctrl.GetStringValueAt(obj, 1)
# how could I change the above value here?
col2 = self.list_ctrl.GetStringValueAt(obj, 2)
col3 = self.list_ctrl.GetStringValueAt(obj, 3)
But what if I want to change the value of a string given the obj in this current loop and column index? The documentation doesn't seem to have a method that takes the current object and a column index as a parameter, so how could I do this (without removing and repopulating the element)?
I see from the docs that there is a SetValue(modelObjects, preserveSelection=False) method but it sets the list of modelObjects to be displayed by the control, which is not what I'm trying to do.
Is there a SetStringValueAt(modelObject, columnIndex) method or workaround to do the same thing in this context?
You can turn on cell "editability" by setting your ObjectListView instance's cellEditMode. Something like this would work:
self.list_ctrl.cellEditMode = ObjectListView.CELLEDIT_SINGLECLICK
The ObjectListView documentation talks about this here:
I also mention it in the following tutorial:
UPDATE: Iterating over objects and changing them programmatically is a bit trickier. Fortunately, ObjectListView provides RefreshObject, which allows us to change a specific object and then refresh it. Here's an example script:
