Some Error in Rendering or so

[svn-josh]

so i got a small scrolable button frame wiht some entrys and a search bar:

# create archive frame & search bar
self.archiv_frame = customtkinter.CTkFrame(self, corner_radius=0, fg_color="transparent")
self.archiv_frame.rowconfigure(1, weight=1)
self.archiv_frame.columnconfigure(0, weight=1)
self.archiv_frame_scrollable_button_frame = ScrollableLabelButtonFrame(
master=self.archiv_frame, width=300, corner_radius=0, command=self.archiv_button_reprint_event)
self.archiv_frame_scrollable_button_frame.grid(row=1, column=0, columnspan=2, padx=20, pady=20, sticky="nsew")

self.archiv_frame_search_entry = customtkinter.CTkEntry(self.archiv_frame)
self.archiv_frame_search_entry.grid(row=0, column=0, padx=20, pady=[20, 0], sticky="ew")

self.search_button = customtkinter.CTkButton(self.archiv_frame, text="Suchen", image=self.search_image, command=self.search_archive_thread)
self.search_button.grid(row=0, column=1, padx=[0, 20], pady=[20, 0], sticky="e")

def search_archive_thread(self):
    t = threading.Thread(target=self.search_archive)
    t.start()

def search_archive(self):
    search_term = self.archiv_frame_search_entry.get()
    archive_list = self.ftp.get_archiv_list()
    if archive_list:
        self.archiv_frame_scrollable_button_frame.clear_items()
        for item in archive_list:
            if search_term.lower() in item.lower():
                self.archiv_frame_scrollable_button_frame.add_item(item)

When Clicking the Search Button once, everything is fine, but when clicking a second time it throws a error i think is related to some kind of Rendering

Also my code again but this time in pastebin: https://pastebin.com/RbPPnZdB

This is probably due to the use of Threading. Modifying widgets in thread differents from main thread is dangerous because of the non-thread-safe property of Tkinter.
Try in a first place to remove the thread !

the problem without using theading ist whenever the search button is pressed the whole app times out and gets no response from windows for like 10sek ...... hmm....

You can still use threads just don't do any tkinter operations in a different thread. You can still use event_generate in a different thread to act as a callback
