Elenco di tutti gli eventi Tkinter

Question

In Python tkinter modulo, <Button-1>, <Button-2> e <Button-3> vengono utilizzati per identificare i clic del pulsante del mouse rispettivamente per i pulsanti sinistro, centrale e destro.

Allo stesso modo, <KeyPress-Return> viene utilizzato per la pressione del tasto di ritorno.

Dove posso trovare un elenco di tutti questi eventi, compresi i nomi dei vari tasti della tastiera?

Tcl bind manual non dispone di quelli.

Answer 1

un elenco generale per Associazioni ed eventi sono disponibili sul effbot.org o nel docs provided by New Mexico Tech, mentre il nome di diverse chiavi sono elencati here oltre al original documentation.

Ecco una sintesi degli eventi più comuni con alcuni nomi di pressione dei tasti spiegato:

<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.
