问题描述

在Python中 tkinter 模块,< Button-1> -2> < Button-3> 分别用于识别左,中,右按钮的鼠标按钮点击。

In Python tkinter module, <Button-1>, <Button-2> and <Button-3> are used to identify mouse button clicks for left, middle and right buttons respectively.

同样,< KeyPress-Return> 用于返回键按。

在哪里可以找到所有这些事件的列表,包括各种键盘键的名称?

Where can I find a list of all such events, including the names for the various keyboard keys?

Tcl绑定手册没有这些。

推荐答案

有关绑定和事件的常规列表,请参见 effbot.org 或在文档,而列出了几个密钥的名称这里除了原始文档

A general list for Bindings and Events can be found on effbot.org or in the docs provided by New Mexico Tech whereas the name of several keys are listed here in addition to the original documentation.

以下是一些解释了一些按键名称的常见事件的摘要:

Here's a summary of the most common events with some keypress names explained:

<Button-1>        Button 1 is the leftmost button, button 2 is the middle button
                  (where available), and button 3 the rightmost button.

                  <Button-1>, <ButtonPress-1>, and <1> are all synonyms.

                  For mouse wheel support under Linux, use Button-4 (scroll 
                  up) and Button-5 (scroll down)

<B1-Motion>       The mouse is moved, with mouse button 1 being held down (use
                  B2 for the middle button, B3 for the right button).

<ButtonRelease-1> Button 1 was released. This is probably a better choice in 
                  most cases than the Button event, because if the user 
                  accidentally presses the button, they can move the mouse 
                  off the widget to avoid setting off the event.

<Double-Button-1> Button 1 was double clicked. You can use Double or Triple as 
                  prefixes.

<Enter>           The mouse pointer entered the widget (this event doesn’t mean 
                  that the user pressed the Enter key!).

<Leave>           The mouse pointer left the widget.

<FocusIn>         Keyboard focus was moved to this widget, or to a child of 
                  this widget.

<FocusOut>        Keyboard focus was moved from this widget to another widget.

<Return>          The user pressed the Enter key. For an ordinary 102-key 
                  PC-style keyboard, the special keys are Cancel (the Break 
                  key), BackSpace, Tab, Return(the Enter key), Shift_L (any 
                  Shift key), Control_L (any Control key), Alt_L (any Alt key), 
                  Pause, Caps_Lock, Escape, Prior (Page Up), Next (Page Down), 
                  End, Home, Left, Up, Right, Down, Print, Insert, Delete, F1, 
                  F2, F3, F4, F5, F6, F7, F8, F9, F10, F11, F12, Num_Lock, and 
                  Scroll_Lock.

<Key>             The user pressed any key. The key is provided in the char 
                  member of the event object passed to the callback (this is an 
                  empty string for special keys).

a                 The user typed an "a". Most printable characters can be used 
                  as is. The exceptions are space (<space>) and less than 
                  (<less>). Note that 1 is a keyboard binding, while <1> is a 
                  button binding.

<Shift-Up>        The user pressed the Up arrow, while holding the Shift key 
                  pressed. You can use prefixes like Alt, Shift, and Control.

<Configure>       The widget changed size (or location, on some platforms). The 
                  new size is provided in the width and height attributes of 
                  the event object passed to the callback.

<Activate>        A widget is changing from being inactive to being active. 
                  This refers to changes in the state option of a widget such 
                  as a button changing from inactive (grayed out) to active.


<Deactivate>      A widget is changing from being active to being inactive. 
                  This refers to changes in the state option of a widget such 
                  as a radiobutton changing from active to inactive (grayed out).

<Destroy>         A widget is being destroyed.

<Expose>          This event occurs whenever at least some part of your 
                  application or widget becomes visible after having been
                  covered up by another window.

<KeyRelease>      The user let up on a key.

<Map>             A widget is being mapped, that is, made visible in the 
                  application. This will happen, for example, when you call the 
                  widget's .grid() method.

<Motion>          The user moved the mouse pointer entirely within a widget.

<MouseWheel>      The user moved the mouse wheel up or down. At present, this 
                  binding works on Windows and MacOS, but not under Linux.

<Unmap>           A widget is being unmapped and is no longer visible.

<Visibility>      Happens when at least some part of the application window 
                  becomes visible on the screen.
