Question

我的程序有一个库，可以打开一个新窗口

这是库（名为make_entry）：

use Hexavel\Console\AppNameCommand;
use Illuminate\Console\Events\ArtisanStarting;
use Illuminate\Contracts\Events\Dispatcher;
use Illuminate\Support\ServiceProvider;

class NameCommandProvider extends ServiceProvider
{
    /**
     * Register any other events for your application.
     *
     * @param  \Illuminate\Contracts\Events\Dispatcher  $events
     * @return void
     */
    public function boot(Dispatcher $events)
    {
        $events->listen(ArtisanStarting::class, function ($event) {
            $event->artisan->resolve('command.app.name');
        }, -1);
    }

    /**
     * Register the service provider.
     *
     * @return void
     */
    public function register()
    {
        $this->app->singleton('command.app.name', function ($app) {
            return new AppNameCommand($app['composer'], $app['files']);
        });
    }
}

如果我自己运行这个库，那么一切正常，但是当我从另一个程序导入它时，唯一不起作用的是from tkinter import * def Create(): Window = Tk() # window Window.geometry("900x500+50+50") # heightxwidth+x+y mainPanel = Canvas(Window, width = 900, height = 500) # main screen mainPanel.pack() anyvar = StringVar() # the text in the entry entry = Entry(mainPanel, width = 40, font = ("Purisa", 12, "bold"), justify = "center", textvariable = anyvar) # the entry mainPanel.create_window(200, 100, window = entry) anyvar.set("This doesnt work!!!!!") Window.mainloop() #Create()。

这是我导入它的地方:(大部分代码被删除）

anyvar.set("This doesnt work!!!!!")

有没有办法解决这个问题而不删除任何窗口？

你有两个Tk（）实例混淆了Tkinter。我猜测StringVar（）将转到另一个（第一个）实例。相反，将唯一的实例传递给函数，并使用Toplevel作为新窗口。

from tkinter import *

def Create(root):
    window=Toplevel(root)    
    window.geometry("900x500+50+50") # heightxwidth+x+y

    mainpanel = Canvas(window, width = 900, height = 500) # main screen
    mainpanel.pack()

    anyvar = StringVar() # the text in the entry
    entry = Entry(mainpanel, width = 40, font = ("Purisa", 12, "bold"), justify = "center", textvariable = anyvar) # the entry
    mainpanel.create_window(200, 100, window = entry)
    anyvar.set("This doesnt work!!!!!")

和

from tkinter import *
Window = Tk()
import make_entry
make_entry.Create(Window)
Window.mainloop()

StringVar.set（“...”）在多个tkinter窗口中不起作用
