Wxpython Ultimatelistctrl Error After Deleting Row

I have been working with wxPython and UltimateListCtrl to create a GUI for a project. For my GUI is have a few panels that have UltimateListCtrls and have I run into an issue I ca

Solution 1:

You can get around this issue by rebuilding the listctrl using the list t_col1.

import wx
from wx.lib.agw import ultimatelistctrl as ULC

classMywin(wx.Frame):
    t_col1 = ['PICTURE 1', 'PICTURE 2', 'PICTURE 3', 'PICTURE 4', 'PICTURE 5', 'PICTURE 6', 'PICTURE 7']
    t_col4 = ['1', '1', '3', '5', '5', '1', '2']

    def__init__(self, parent, title):
        wx.Frame.__init__(self, parent)
        box2 = wx.BoxSizer(wx.VERTICAL)
        title = wx.StaticText(self, wx.ID_ANY, label='Pictures On Frame:')
        box2.Add(title, 0, wx.ALL, 5)
        self.list = ULC.UltimateListCtrl(self, agwStyle = ULC.ULC_REPORT | ULC.ULC_HAS_VARIABLE_ROW_HEIGHT)
        colhead = ["", "File", "Ext", "Size", "Rating"]
        colwidth = [30, 300, 45, 45, 45]
        for x inrange(0, len(colhead)):
            self.list.InsertColumn(x, colhead[x], width=colwidth[x])
        box2.Add(self.list, 1, wx.EXPAND)
        btnSizer2 = wx.BoxSizer(wx.HORIZONTAL)
        btnC = wx.Button(self, label="Clear")
        btnC.Bind(wx.EVT_BUTTON, self.on_clear)
        btnSizer2.Add(btnC, 0, wx.ALL | wx.CENTER, 5)
        box2.Add(btnSizer2, 1, wx.EXPAND)
        self.SetSizer(box2)
        self.SetTitle('Picture Frame Selector')
        self.Centre()
        self.Maximize()
        self.CreateList()
        self.Show()

    defCreateList(self):
        rb_list = ["1", "2", "3", "4", "5"]
        for x inrange(0 , len(self.t_col1)):
            self.list.InsertStringItem(x, '')
            cBox = wx.CheckBox(self.list)
            self.list.SetItemWindow(x, 0, cBox)
            self.list.SetStringItem(x, 1, self.t_col1[x])
            self.list.SetStringItem(x, 2, '.jpg')
            dBox = wx.ComboBox(self.list, value=self.t_col4[x], choices=rb_list, style=wx.CB_READONLY)
            self.list.SetItemWindow(x, 4, dBox, expand=True)

    defon_clear(self, event):
        for x inrange(len(self.t_col1) -1 , -1, -1):
            if self.list.GetItemWindow(x, 0).IsChecked():
                self.t_col1.pop(x)
        self.list.DeleteAllItems()
        self.CreateList()
        event.Skip()

if __name__ == "__main__":
    ex = wx.App()
    Mywin(None, 'Row Delete Issue')
    ex.MainLoop()

Note that items are removed from the list in reverse, for obvious reasons and I use list.pop() so that I can use its position from range rather than list.remove() I have not allowed for saving changes made to choices under the Rating column.
