Query regarding a desired feature in PySimpleGUI TK version - input

Question

I have built a graphic oriented package using the Graph element. I need to do keyboard input based on Graph Element coordinates. Currently I am using the events that come in from the keyboard to place characters on the Graph element using draw_text. It works but is a bit slow and I get into problems with interpreting the key codes I get back from different platforms and the overhead with me doing the echoing back on to the Graph element does not help.
My Question. In PySimpleGui(Tk) is there a way to use the Tk Entry function directly on Graph Coordinates?

IMO, it can be done like your request, but much complex.
Here only a simple way to enter text on a Graph element.
import PySimpleGUI as sg
font = ('Courier New', 16, 'bold')
layout = [
[sg.Input(expand_x=True, key='INPUT')],
[sg.Graph((320, 240), (0, 0), (320, 240), enable_events=True, key='GRAPH',
background_color='green')],
]
window = sg.Window('Draw Text', layout, margins=(0, 0), finalize=True)
entry, graph = window['INPUT'], window['GRAPH']
while True:
event, values = window.read()
if event == sg.WIN_CLOSED:
break
elif event == 'GRAPH':
location, text = values['GRAPH'], values['INPUT']
if text:
graph.draw_text(text, location, font=font, color='white', text_location=sg.TEXT_LOCATION_LEFT)
window.close()
Here, something like your request, but much complex and tkinter code required.
import PySimpleGUI as sg
def entry_callback(event, graph, entry_id, font, location, color):
widget = event.widget
text = widget.get()
graph.widget.delete(entry_id)
if text:
graph.draw_text(text, location=location, font=font, color=color, text_location='sw')
font = ('Courier New', 16, 'bold')
layout = [
[sg.Graph((320, 240), (0, 0), (320, 240), enable_events=True, key='GRAPH',
background_color='green')],
]
window = sg.Window('Draw Text', layout, margins=(0, 0), finalize=True)
graph = window['GRAPH']
while True:
event, values = window.read()
if event == sg.WIN_CLOSED:
break
elif event == 'GRAPH':
location = tuple(map(int, graph._convert_xy_to_canvas_xy(*values['GRAPH'])))
entry = sg.tk.Entry(graph.widget, font=font, fg='white', bg='green', width=45)
entry_id = graph.widget.create_window(*location, window=entry, anchor="sw")
entry.bind('<Return>', lambda event, graph=graph, entry_id=entry_id, font=font, location=values['GRAPH'], color='white':entry_callback(event, graph, entry_id, font, location, color))
entry.focus_force()
window.close()
