Wxpython, how to create wx.KeyEvent with given key code?

Question

I'm trying to create a wx.KeyEvent object, I need it to emulate key press in wx.TextCtrl. I don't want to propagate the event (if possible), just create an object. Is there a way to do this?

I've looked at wx.KeyEvent page on the wxpython.org, yet I didn't find any useful information. My only hint is that maybe I could create a wx.Event object and give it the parameters I want?

EDIT: I've tried instantiating an Event object with eventType=wx.EVT_KEY_DOWN, but I get the exception saying that it cannot be subclassed/instantiated. No wonder, cause how would I even pass parameters into it.

Creating low level events is not a good idea. Describe what you are trying to do, and we may find a better way. You can SetInsertPoint, select, edit, and what not. — Petr Blahos

I am trying to implement auto completion in wx.RichTextCtrl, If I remember it correctly then SetInsertionPoint couldn't help me, as I am also styling the text depending on the content. for example numbers are of different color than keywords or parantheses. I found that only EmulateKeyPress worked for me. Other forms would only work partially. — Chris P.

You can generate keys, text and mouse actions with wx.UIActionSimulator https://wxpython.org/Phoenix/docs/html/wx.UIActionSimulator.html

i.e.

keyinput = wx.UIActionSimulator()
keyinput.Char(ord("z"))
keyinput.Char(ord("\t"))

would simulate a "z" followed by a tab

Actions available are:

> Char  Press and release a key.
> KeyDown   Press a key.
> KeyUp Release a key.
> MouseClick    Click a mouse button.
> MouseDblClick Double-click a mouse button.
> MouseDown Press a mouse button.
> MouseDragDrop Perform a drag and drop operation.
> MouseMove Move the mouse to the specified coordinates.
> MouseUp   Release a mouse button.
> Text  Emulate typing in the keys representing the given string.

Thank you! This is exactly what I needed.

@Rolf of Saxony and what if I need to do the reverse thing - simulate an EVT_BUTTON event when a hotkey press is detected?

@ivan866 Best create a question with your scenario described in detail.

Note that wxUIActionSimulator requires wxWidgets to have been built with XTest support, which is currently not the case on Debian (see: bugs.debian.org/cgi-bin/bugreport.cgi?bug=1037164).
