mvKey_Prior / mvKey_Next mapping issue

[Dong-gwan]

Dear PyGui version:

2.3.1

Python version:

3.14.5

Operating system:

Windows 11 25H2

My issue/question:

I was using Python 3.14.3 + dpg 2.2, but recently updated to Python 3.14.5 + dpg 2.3.1.

After that, dpg.mvKey_Prior and dpg.mvKey_Next stopped working.

Upon checking the cause, I found that while dpg.mvKey_Prior outputs the previous value of 33, the actual key value is 517.

Considering that dpg.mvKey_Up is showing 515, I suspect there might have been some omission during the mapping value change.

It is working fine now that I have switched back to dpg 2.2.

Steps to reproduce:

1. add_key_press_handler
2. press key

Expected behavior:

Events are triggered on Page Up/Down keys

Screenshots:

N/A

Standalone, minimal, complete and verifiable example:

import dearpygui.dearpygui as dpg


def onKeyPressed(sender=None, appData=None, userData=None):
    print(f"key pressed: {appData}")


dpg.create_context()
dpg.create_viewport(title='123')

with dpg.handler_registry():
    dpg.add_key_press_handler(key=dpg.mvKey_Up, callback=onKeyPressed)
    dpg.add_key_press_handler(key=dpg.mvKey_Prior, callback=onKeyPressed)
    dpg.add_key_press_handler(key=dpg.mvKey_Next, callback=onKeyPressed)
    
print(f"mvKey_Up: {dpg.mvKey_Up}")
print(f"mvKey_Prior: {dpg.mvKey_Prior}")
print(f"mvKey_Next: {dpg.mvKey_Next}")

dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
