In download_images() I want to prompt the user if the last updated data for the data is correct and if they want to proceed. To do this, I am using a popup window. However, after the user selects 'yes' the code in download_images() is never resumed.
def download_images(self, pat, name):
tableau_config = {
"tableau_prod": {
"server": "https://tableau.****.com",
"api_version": "3.19",
"personal_access_token_name": name,
"personal_access_token_secret": pat,
"site_name": "Consolidated",
"site_url": "Consolidated",
}
}
connection = TableauServerConnection(
config_json=tableau_config, env="tableau_prod", ssl_verify=False
)
connection.sign_in()
wb = connection.query_workbook(
workbook_id="3eed5185"
)
# Cred check
if wb.status_code != 200:
self.okPopup("Invalid Credentials, try again.")
workbook_views = json.loads(wb.content.decode("utf-8").replace("'", '"'))[
"workbook"
]["views"]["view"]
for rows in workbook_views:
if rows["name"] == "Senior Management (CIO)":
self.yesNoPopup(
f"The data was last updated on {rows['updatedAt'][:10]}. Would you like to proceed?"
)
if not self.yesNoValue:
break

I believe this issue has something to do with how the root.mainloop and popup.mainloop interact. I've tried closing the main window, and the code will resume executing, but then, I don't have my main window anymore. I've tried popup.quit() instead of popup.destroy() and this also works but leaves the popup window open for the rest of the execution.
You shouldn't be calling mainloop a second time. As a general rule of thumb you should call it exactly once during the life of the program.
Instead, use the wait_window method which will not return until the window has been destroyed.

popup = tk.Toplevel()

popup.wait_window()
