解决方案思路来自https://stackoverflow.com/questions/6920302/how-to-pass-arguments-to-a-button-command-in-tkinter 其实使用的都是封装的方法,只是有不同的实现。 方案一:lambda函数 个人比较喜欢这个方法 ttk.Button(frame,text='button',command=lambda:func(param)) 值得注意的是,这里存在一个小细节,不了解...

<Button-1>事件中,event会返回两个坐标数组,其中rootx, rooty是相对于窗口左上角顶点的坐标,因此Label只能创建在主窗口中。 在文本框里,文字始终在文本框内部,而且可以滚动,因此使用event.x, event.y更加方便。 需要注意的是,这篇文章只是在文本框实现的小功能,并不是之前那篇文章的升级,因此需要注意使用场合和...

pass ttk.Button(frame, command=lambda: thread.submit(run_in_thread, callback=on_data_received)) 1. 2. 3. 4. 5. 6. 7. 8. 9. 如果忽略 thread 的话,这样的写法和传统的同步代码写法并没有什么区别,类似于button.on_click = lambda: do_something() ...
pass ttk.Button(frame, command=lambda: thread.submit(run_in_thread, callback=on_data_received)) 如果忽略 thread 的话,这样的写法和传统的同步代码写法并没有什么区别,类似于button.on_click = lambda: do_something() 其实,Python 中 concurrent.futures 的 Future 就有类似的方法: ...
In many ways, a button is just a label that you can click! The same keyword arguments that you use to create and style a Label will work with Button widgets. For example, the following code creates a button with a blue background and yellow text. It also sets the width and height ...
To do that, we can use the resizable() method, which takes two boolean arguments: width specifies whether the window can be horizontally resized. height specifies whether the window can be vertically resized. If you pass False for both arguments, you will disable resizing in both directions. ...
It's also possible to pass arguments to after callbacks: # run print('hello') after 1 secondany_widget.after(1000,print,'hello')# run foo(bar, biz, baz) after 3 secondsany_widget.after(3000,foo,bar,biz,baz) Threads can handle arguments too, but they do it slightly differently: ...
