wxPython create a huge clickable list with sub-lists during run time?

In wxPython, you can create a clickable list with sub-lists using the wx.ListCtrl widget. To make it behave like a tree-like structure with sub-lists, you can use the wx.LC_REPORT style and add columns to represent the hierarchy. Here's a step-by-step guide on how to create a clickable list with sub-lists using wxPython:

1. Import the required modules:

pythonCopy code
import wx

1. Create the main frame and panel:

pythonCopy code
class MyFrame(wx.Frame):

    def __init__(self, parent, title):

        super(MyFrame, self).__init__(parent, title=title, size=(500, 400))



        self.panel = wx.Panel(self)



        # Create the list control

        self.list_ctrl = wx.ListCtrl(self.panel, style=wx.LC_REPORT)



        # Add columns to represent the hierarchy

        self.list_ctrl.InsertColumn(0, "Item")

        self.list_ctrl.InsertColumn(1, "Sub-Item")



        # Bind the click event

        self.list_ctrl.Bind(wx.EVT_LIST_ITEM_ACTIVATED, self.on_item_click)



        # Create a sizer to layout the list control

        sizer = wx.BoxSizer(wx.VERTICAL)

        sizer.Add(self.list_ctrl, 1, wx.EXPAND)

        self.panel.SetSizer(sizer)



    def on_item_click(self, event):

        # Get the selected item and sub-item

        item = event.GetIndex()

        sub_item = self.list_ctrl.GetItem(item, 1).GetText()



        # Handle the click event based on the selected item and sub-item

        print(f"Clicked: {sub_item}")



if __name__ == "__main__":

    app = wx.App(False)

    frame = MyFrame(None, "Clickable List with Sub-Lists")

    frame.Show()

    app.MainLoop()

In this example, we create a wx.Frame with a wx.ListCtrl widget that has two columns. When an item in the list is double-clicked, the on_item_click method is called, and you can handle the click event based on the selected item and sub-item.

You can add items and sub-items dynamically to the list using the InsertItem and SetItem methods of the wx.ListCtrl widget. This way, you can create a huge clickable list with sub-lists during runtime.
