Python Tkinter wraps widgets in a frame if they reach the end of the screen

Is there something like a new line package for the Tk geometry manager? I use the package to place widgets inside a frame. On a high-resolution screen, widgets are installed next to each other. However, if you place it on a smaller screen, the widgets will work outside the room in the frame.

We mainly go from:

Before

in

after

You can see how it disables the Processors input field. Relevant Code:

options_frame = ttk.LabelFrame(
        parent_frame, text="Blast Options")
options_frame.pack(side=TOP, fill=X, expand=1, padx=5, pady=5)
        self._set_up_blast_options(options_frame)

def _set_up_blast_options(self, options_frame):
    self.evalue = Tkinter.DoubleVar()
    self.evalue.set(1)
    self.word_size = Tkinter.IntVar()
    self.word_size.set(4)
    self.penalty_mismatch = Tkinter.DoubleVar()
    self.penalty_mismatch.set(-4)
    self.min_d_match = Tkinter.IntVar()
    self.min_d_match.set(5)
    self.proc_count = Tkinter.IntVar()
    self.proc_count.set(cpu_count())

    # evalue
    e_value_label = ttk.LabelFrame(
        options_frame, text="e-Value Threshold")
    e_value_entry = ttk.Entry(e_value_label)
    e_value_entry.insert(0, self.evalue.get())
    e_value_entry.bind('<Return>', self._validate_e_value)
    e_value_entry.bind('<FocusOut>', self._validate_e_value)
    e_value_label.pack(side=LEFT, expand=1, pady=5, padx=5, fill=X)
    e_value_entry.pack(side=TOP, expand=1, pady=5, padx=5, fill=X)

    # word size
    word_size_label = ttk.LabelFrame(
        options_frame, text="Word Size")
    word_size_entry = ttk.Entry(word_size_label)
    word_size_entry.insert(0, self.word_size.get())
    word_size_entry.bind('<Return>', self._validate_word_value)
    word_size_entry.bind('<FocusOut>', self._validate_word_value)
    word_size_label.pack(side=LEFT, expand=1, pady=5, padx=5, fill=X)
    word_size_entry.pack(side=TOP, expand=1, pady=5, padx=5, fill=X)

    penalty_mismatch_label = ttk.LabelFrame(
        options_frame, text="Penalty Mismatch")
    penalty_mismatch_entry = ttk.Entry(penalty_mismatch_label)
    penalty_mismatch_entry.insert(0, self.penalty_mismatch.get())
    penalty_mismatch_entry.bind(
        '<Return>', self._validate_penalty_mismatch_value)
    penalty_mismatch_entry.bind(
        '<FocusOut>', self._validate_penalty_mismatch_value)
    penalty_mismatch_label.pack(side=LEFT, expand=1, pady=5,
                                padx=5, fill=X)
    penalty_mismatch_entry.pack(side=TOP, expand=1, pady=5,
                                padx=5, fill=X)
    # Min D Nucleotides
    min_d_match_label = ttk.LabelFrame(
        options_frame, text="Minimal Number of D Nucleotides")
    min_d_match_entry = ttk.Entry(min_d_match_label)
    min_d_match_entry.insert(0, self.min_d_match.get())
    min_d_match_entry.bind(
        '<Return>', self._validate_min_match_value)
    min_d_match_entry.bind(
        '<FocusOut>', self._validate_min_match_value)
    min_d_match_label.pack(side=LEFT, expand=1, pady=5, padx=5, fill=X)
    min_d_match_entry.pack(side=TOP, expand=1, pady=5, padx=5, fill=X)

    # how many cpus to use
    proc_count_label = ttk.LabelFrame(
        options_frame, text="Processors")
    proc_count_entry = ttk.Entry(proc_count_label)
    proc_count_entry.insert(0, self.proc_count.get())
    proc_count_entry.bind(
        '<Return>', self._validate_proc_count_value)
    proc_count_entry.bind(
        '<FocusOut>', self._validate_proc_count_value)
    proc_count_label.pack(side=LEFT, expand=1, pady=5, padx=5, fill=X)
    proc_count_entry.pack(side=TOP, expand=1, pady=5, padx=5, fill=X)
