将GUI添加到Python脚本

-1

我试图将GUI（tkinter）添加到我的脚本中，但无济于事。如果有人能帮助我，我会很感激。我正在使用Python 3.6，我认为最新的opencv？将GUI添加到Python脚本

我只在2周前开始编程。所以，有点新到这一切。基本上，我想创建一个窗口，从我的文件夹中选择图像，然后通过脚本进行处理，以便每当我想使用其他图像时，我都不必更改脚本。我希望这是有道理的..

这是我从youtube从Chris Dahms采取的脚本，并设法将其更改为我想要的。

尝试并更具体地了解您所寻找的内容，并且只包含与您的问题直接相关的代码。你会得到更多有用的答案，因为人们会知道你需要什么帮助。 – darrenvba

我的不好，这是我第一次尝试在这里问问题。我想添加GUI到脚本。我想创建一个窗口，从我的文件夹中选取图像，然后通过脚本处理它，以便每当我想使用其他图像时，我都不必更改脚本。我希望有道理..我会再次编辑说明.. 谢谢你的答复。 –

如果所有你想要的窗口选择一个文件，然后这应该工作。

import Tkinter 
from Tkinter import * 
import tkSimpleDialog 
from tkFileDialog import askopenfilename 

master = Tk() 
master.withdraw() 
my_file = askopenfilename() 
mainloop()

谢谢你，它的工作原理..但是对于Python 3，只是改为tkinter，第三行改为从tkinter导入simpledialog，第四行改为从tkinter.filedialog导入askopenfilename并且它应该运行.. 再次感谢您帮助我 –

我建议Gtk3您的GUI。这里有一个简单的Gtk窗口按钮：

#!/usr/bin/env python3 

import gi 
gi.require_version('Gtk', '3.0') 
from gi.repository import Gtk 

class Window(Gtk.Window): 
    def __init__(self): 
     Gtk.Window.__init__(self) 
     self.connect('destroy', lambda q: Gtk.main_quit()) 

     button = Gtk.Button("Gtk.Button") 
     button.connect("clicked", self.on_button_clicked) 

     grid = Gtk.Grid() 
     grid.attach(button, 0, 0, 1, 1) 

     self.add(grid) 
     self.show_all() 

    def on_button_clicked(self, button): 
     print("Gtk.Button was clicked") 

w = Window() 
Gtk.main()

非常感谢你的回复。我会尝试在我的项目中使用它。在这里我撕裂同事和我的头发，因为我没有足够的能力来完成的东西..再次感谢你.. –
