的文档中找到有关绑定和事件的常规列表,而此处除了原始文档之外,还列出了几个键的名称。

以下是最常见事件的摘要,并解释了一些按键名称:

<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.
