我用click编写了一个CLI。现在我想知道是否可以使用 Tkinter 将其集成到 GUI 中。 我知道有多种方法可以将控制台嵌入到 Tkinter 中,但我想具体知道是否可以将我的 CLI 添加到其中(通过“合理”的努力)。
所以我有一个脚本:
@cli.command()
def myfunction()
print("My Stuff")
现在我想构建一个 Tkinter GUI,其中有一个命令行,这样如果我在那里输入 myfunction
,它就会调用并执行这个 myfunction
这可能吗?或者我应该只使用 CLI 下的代码并用它构建一个独立于 CLI 的 Tkinter 应用程序?
最佳答案
为了好玩,我刚刚制作了这个 tkinterify
,它可以满足您的要求。
import tkinter
import click
import sys
from io import StringIO
def tkinterify(cli_group, app_name="Tkinterified App"):
# Create and configure root
root = tkinter.Tk()
root.wm_title(app_name)
tkinter.Grid.rowconfigure(root, 0, weight=1)
tkinter.Grid.columnconfigure(root, 0, weight=1)
# Create and configure frame
frame = tkinter.Frame(root)
frame.grid(row=0, column=0, sticky="nsew")
frame.columnconfigure(0, weight=1)
frame.columnconfigure(1, weight=1)
frame.columnconfigure(2, weight=1)
frame.rowconfigure(0, weight=1)
frame.rowconfigure(1, weight=1)
initial_output = "Valid commands:\n"
initial_command_name_list = list(cli_group.commands.keys())
for available_command_name in initial_command_name_list:
initial_output = initial_output + " " + available_command_name + "\n"
initial_output = initial_output + "Ready for input."
# Some GUI widgets
run_string = tkinter.StringVar()
entry_run = tkinter.Entry(root, textvariable=run_string, width=50)
scrollbar_widget = tkinter.Scrollbar(root)
text_widget = tkinter.Text(root)
def clear_callback():
# Because the text widget is usually disabled, we have to explicitly enable it before we can write to it.
text_widget.config(state='normal')
text_widget.delete(1.0, tkinter.END)
text_widget.insert(tkinter.END, initial_output)
text_widget.config(state='disabled')
def run_callback():
command_args = []
try:
command_parts = run_string.get().split()
command_name = command_parts[0]
except IndexError:
return
if len(command_parts) > 1:
command_args = command_parts[1:]
if command_name:
try:
# Redirect stdout so we can read the output into a string for display within out GUI
real_stdout = sys.stdout
fake_stdout = StringIO()
sys.stdout.flush()
sys.stdout = fake_stdout
# Obtain list of available commands
available_commands = cli_group.commands
command_name_list = list(cli_group.commands.keys())
if command_name in command_name_list:
try:
# Make a fake context in which to run the command
context = available_commands[command_name].make_context("tkinter", command_args)
# Invoke the command within the fake context
available_commands[command_name].invoke(context)
except click.exceptions.UsageError as e:
print(e)
print(initial_output)
else:
print("Command not found.\n")
print(initial_output)
# Put stdout back
sys.stdout.flush()
sys.stdout = real_stdout
sys.stdout.flush()
output_string = fake_stdout.getvalue()
fake_stdout.close()
# Update the text output widget
text_widget.config(state='normal')
text_widget.delete(1.0, tkinter.END)
text_widget.insert(tkinter.END, output_string)
text_widget.config(state='disabled')
except IndexError:
pass
# More GUI widgets
button_run = tkinter.Button(root, text="Run", command=run_callback)
button_clear = tkinter.Button(root, text="Clear", command=clear_callback)
text_widget.delete(1.0, tkinter.END)
text_widget.insert(tkinter.END, initial_output)
entry_run.grid(row=0, column=0, sticky="new")
button_run.grid(row=0, column=1, sticky="n")
button_clear.grid(row=0, column=2, sticky="n")
text_widget.grid(row=1, column=0, columnspan=2, sticky="nsew")
scrollbar_widget.grid(row=1, column=2, sticky="ns")
scrollbar_widget.config(command=text_widget.yview)
text_widget.config(yscrollcommand=scrollbar_widget.set)
text_widget.config(state='disabled')
root.mainloop()
我已将其放在 github 上:https://github.com/rbricheno/tkinterify示例如下:
import click
from tkinterify import tkinterify
@click.group()
def cli():
pass
@click.command()
def my_function():
print("My Stuff")
@click.command()
def my_other_function():
print("More Things")
cli.add_command(my_function)
cli.add_command(my_other_function)
tkinterify(cli)
如果您的脚本有大量输出或在其他方面很复杂,您可能需要修改它。我还没有测试它如何处理参数。希望这能让您了解如何做您想做的事情。
主要技巧是将我们的点击
命令添加到组
中。添加它们后,我们可以使用 the_group.commands
