Ok team, I need help with this one, I'm at a loss. I will not be able to provide a working example as the GUI I'm using you likely don't have (it's the TradeZero ZeroPro's stock/options trading desktop program that I use to place trades manually, would like to automate it), so I will do my best to provide screenshots and code samples so I can get some direction regardless.
This is what the window looks like:
Without going into too much here, the dropdown/combobox in question is the Strike
. It's not a text-editable box, it only wants a selection from the dropdown, which looks like this when expanded:
As you can see, there's a scroll wheel available as there's too many items. The item I want to select is "430.00", which is about half way down that list.
I will show you the code that I've created with the number of attempts I've tried and their results. I've also printed the outputs of the element's properties to help give you some insight. I'm at a loss for how to "select" 430.00
from that dropdown menu, between pywinauto
constantly changing its focus
to the Root
text box, and being at it for hours, I'm stuck!
# Format the strike_price as a string with two decimal places, like the list items in the dropdown menu
strike_price_str = "{:.2f}".format(strike_price)
print(strike_price_str)
>>> 430.00
# Inspect the dropdown menu's properties
strike_dropdown_element = option_chain_window_element["StrikeComboBox"]
print("Dropdown list's combo box properties:")
print(strike_dropdown_element.get_properties(), "\n")

# Timings set to 0! The gui keeps auto-focusing on the first text box in the top
# left of the window for some reason, so I have to keep re-setting the focus on
# the dropdown menu. This is very annoying, and makes the process extremely slow.
# It "scrolls down" one option every 2-3 seconds because of this weird behaviour,
# and this dropdown has many elements in it so this is not an acceptable solution.

except Exception as e:
scroll_count += 1
# This doesn't work either. It should scroll down more and more each time the

# very annoying!
I figured out that, it isn't the ComboBox that I should be trying to interact with, but the EDIT element that's attached to it!
Edit - '' (L23, T463, R89, B483)
['Edit4', 'StrikeEdit']
child_window(auto_id="[Editor] Edit Area",
Knowing that, I was able to make it work with this code:
# Get the strike price EDIT element, and set the value to the strike price
strike_dropdown_edit_element = option_chain_window_element["StrikeEdit"]
# print(strike_dropdown_element.get_value())
strike_dropdown_edit_element.set_text(str(430.00 * 100000))
The values were weird with the edit element too, which I think is just a ZeroPro thing as they have the values of the prices multiplied by one hundred thousand, so that's what I send as the text value and it worked.
