Cannot configure windows height/width when init file is enabled. Expected behavior?

[ultgift]

Hello,

Great thanks to your work, I am enjoying great deal of help for writing a GUI interface to my experiment instruments.
I have noticed while enabling the init file, the window item no longer responds to manually setting height and width.
Is this an intended behavior?

import dearpygui.dearpygui as dpg

dpg.create_context()

# enabling init file.
dpg.configure_app(init_file=os.path.join(os.getcwd(), "dpg.ini"))

with dpg.window() as win_id:
    ...

# configuring height/width: No longer works when init_file is set.
dpg.set_item_height(win_id, 200)
dpg.set_item_width(win_id, 800)

dpg.create_viewport()
dpg.setup_dearpygui()
dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

This is correct behavior. The init file overrides the initial window height/width. You can set them after. i.e.

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.configure_app(init_file="dpg.ini")
dpg.create_viewport()
dpg.setup_dearpygui()

def callback():
    # configuring height/width: No longer works when init_file is set.
    dpg.set_item_height("win", 200)
    dpg.set_item_width("win", 800)


with dpg.window(tag="win"):
    dpg.add_button(label="Press me", callback=callback)



dpg.show_viewport()
dpg.start_dearpygui()
dpg.destroy_context()

Thank you for the reply. I was looking for a way to programmatically initialize the window sizes but it seems that init file will override any configuration commands registered before the rendering loop. I found that adding a one-time initialization inside a custom rendering loop, as shown below works. Would there be any other recommended way of initializing UI items? Thanks again.

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.configure_app(init_file="dpg.ini")
dpg.create_viewport()
dpg.setup_dearpygui()

def callback():
    dpg.set_item_height("win", 200)
    dpg.set_item_width("win", 200)

with dpg.window(tag="win"):
    dpg.add_button(label="Press me", callback=callback)

dpg.show_viewport()


i = 0
while dpg.is_dearpygui_running():
    # custom initialization
    if i == 0 :
        dpg.set_item_height("win", 400)
        i = 1

    dpg.render_dearpygui_frame()

dpg.destroy_context()

After a short while, I found out that just rendering once before the loop will do the trick!

import dearpygui.dearpygui as dpg

dpg.create_context()
dpg.configure_app(init_file="dpg.ini")
dpg.create_viewport()
dpg.setup_dearpygui()

with dpg.window(tag="win"):
    ...

dpg.show_viewport()

# Render once!
dpg.render_dearpygui_frame()

# Initialize!
dpg.set_item_height("win", 400)

dpg.start_dearpygui()
dpg.destroy_context()
