¿Cómo se muestran las sugerencias sobre herramientas en Tkinter?

Question

La información sobre herramientas son pequeños pedacitos de texto que aparecen cuando el mouse se desplaza sobre un widget durante un período de tiempo determinado.

¿Cómo puedo agregar un mensaje de información sobre herramientas a mi aplicación tkinter Python?

Answer 1

La clase Pmw.Balloon del Pmw toolkit para Tkinter dibujará sobre herramientas.

También eche un vistazo a este blog post, que adapta algunos códigos de IDLE utilizados para mostrar sugerencias de herramientas con Tkinter.

Answer 2

Dado que está utilizando Windows 7, la instalación de Python probablemente ya incluya Tix. Utilice el widget Tix.Balloon. Sample code existe en el árbol fuente de Python.

Básicamente, usted crea un widget Tix.Balloon, lo vincula a otros widgets a través de su método .bind_widget y proporciona el mensaje de globo usando su argumento balloonmsg.

Answer 3

No recomendaría usar widgets Tix, ya que Tix ya no es compatible y suele causar muchos problemas.

El siguiente es un example de un texto de ayuda directamente tomada del módulo del pitón idlelib:

# general purpose 'tooltip' routines - currently unused in idlefork 
# (although the 'calltips' extension is partly based on this code) 
# may be useful for some purposes in (or almost in ;) the current project scope 
# Ideas gleaned from PySol 

from tkinter import *

    def __init__(self, button):

      self.button.after_cancel(id) 

    def showtip(self): 
     if self.tipwindow: 
      return 
     # The tip window must be completely outside the button;

     x = self.button.winfo_rootx() + 20

     self.tipwindow = tw = Toplevel(self.button)

     self.showcontents() 

    def showcontents(self, text="Your text here"): 
     # Override this in derived class 
     label = Label(self.tipwindow, text=text, justify=LEFT, 
         background="#ffffe0", relief=SOLID, borderwidth=1) 
     label.pack() 

    def hidetip(self): 
     tw = self.tipwindow 
     self.tipwindow = None 
     if tw: 
      tw.destroy() 


class ToolTip(ToolTipBase): 

    def __init__(self, button, text): 
     ToolTipBase.__init__(self, button) 
     self.text = text 

    def showcontents(self): 
     ToolTipBase.showcontents(self, self.text) 


class ListboxToolTip(ToolTipBase): 

    def __init__(self, button, items): 
     ToolTipBase.__init__(self, button) 
     self.items = items 

    def showcontents(self): 
     listbox = Listbox(self.tipwindow, background="#ffffe0") 
     listbox.pack() 
     for item in self.items: 
      listbox.insert(END, item) 

También puede importar el módulo directamente y utilizarla:

from idlelib.ToolTip import * 

def main(): 
    root = Tk() 
    b = Button(root, text="Hello", command=root.destroy) 
    b.pack() 
    root.update() 
    tip = ListboxToolTip(b, ["Hello", "world"]) 
    root.mainloop() 

if __name__ == '__main__': 
    main() 

estoy usando Python 3.4 , y es posible que otras distribuciones de Python no contengan este módulo ToolTip.

Answer 4

Probé el código en el blog post mencionado por ars, y también probé el código del IDLE lib.

Aunque ambos funcionaron, no me gustó cómo la información sobre herramientas de IDLE tenía un tamaño limitado (tenía que introducir manualmente nuevas líneas como listas separadas) y cómo las sugerencias aparecían inmediatamente en el código de la publicación del blog.

Así que hice un híbrido entre los dos. Se le permite especificar un tiempo de duración de envoltura y vuelo estacionario, sin restricción de cada uno:

Answer 5

He modificado el clase Tooltip crxguy52 ha sugerido. La clase que sigue ahora debería funcionar en casi cualquier caso, siempre que se necesite para crear una instancia que: NW, N, NE, E, SE, S, SW, W.

El único caso en mi clase no gestiona actualmente es aquel en el que la descripción es simplemente más alto que toda la pantalla (probablemente muy raro, pero simplemente ampliándola al pasar manualmente un mayor wraplength puede resolver inmediatamente este caso también).

Answer 6

En primer lugar, me gusta mucho Alberto Vassena's tool tip y traté de comentar su publicación con esta corrección de errores, pero como nuevo usuario no tengo suficientes puntos para hacer un comentario, por lo que estoy respondiendo. Espero que esto sea aceptable.

Hubo un error muy pequeño en Alberto Vassena's excellent answer y ToolTip mejorado.

Bug: Para la etiqueta real su código llama ttk.Label en lugar de tk.Label Esto resultó en el cuadro de información sobre herramientas que se queden pero no el texto real hasta que un evento aún más la interfaz de usuario tal como otro movimiento del ratón o un evento de teclado .
