tkmacosx 1.0.5

Tkmacosx is a Python library extension to the Tkinter module that let you change background color of the button on macOS.

This module provides some modified widgets of Tkinter which fixes many issues with widgets not working properly on macOS platform. For example Button of tkmacosx which looks and feels exactly like a native Tkinter button can change its background and foreground color and has a lot more functionality, Issues with Radiobutton are also fixed with this library. The library also offers some more useful functionality.

Read more about all the classes and methods in the tkmacosx documentation.

Button Widget

The tkmacosx Button widget is alternative to tkinter's Button that supports all features on a macos that were not possible with tkinter Button like background, relief, overrelief, activebackground, and some other features can be set. There is a blue focus ring that tells if the button has the focus or not to disable or hide the focus ring, either set takefocus=0 or focuscolor=''.

• Configurable options for a button widget. Syntax: Button(root, options=value, ...)

  Options	Description
  activebackground	What background color to use when the button is active. The default is system specific. Give tuple of two colors for gradient effect in active background.
  activeforeground	What foreground color to use when the button is active. The default is system specific.
  activeimage	What Image to display when the button is active. No image to display by default. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  activebitmap	What Bitmap to display when the button is active. No bitmap to display by default. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  anchor	Where the text is positioned on the button. For example, anchor=tk.NE would position the text at the top right corner of the button.
  bordercolor	The color to use for the highlight border when the button does not have focus. The default is system-specific. Same as highlightbackground.
  borderless	Blend the button with its parent's background results in a clean look with no square borders. It will change color automatically. The default is False. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  bd or borderwidth	Width of the border around the outside of the button. The default is two pixels.
  bg or background	Normal background color.
  command	Function or method to be called when the button is clicked.
  cursor	Selects the cursor to be shown when the mouse is over the button.
  disabledforeground	The color to use when the button is disabled. The default is system specific.
  focuscolor	The color to use for the focus border when the button have focus. The default is system specific. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  focusthickness	The width of the focus border (pixels). The default is system specific. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  fg or foreground	Normal foreground (text) color.
  font	Text font to be used for the button's label.
  height	The height of the button. The size is given in pixels for both text and images.
  highlightbackground	Color of the focus highlight when the widget does not have focus.
  highlightcolor	The color of the focus highlight when the widget has focus.
  highlightthickness	Thickness of the focus highlight.
  image	Image to be displayed on the button (instead of text).
  justify	How to show multiple text lines: tk.LEFT to left-justify each line; tk.CENTER to center them; or tk.RIGHT to right-justify.
  overbackground	Alternative background to use when the mouse is moved over the widget. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  overforeground	Alternative foreground to use when the mouse is moved over the widget. Note: This option is exclusive to only this libraray, the option doesn't exist by default in tkinter.
  overrelief	The relief style to be used while the mouse is on the button; the default relief is tk.RAISED.
  padx	Additional padding left and right of the text.
  pady	Additional padding above and below the text.
  relief	Specifies the relief type for the button. The default relief is tk.RAISED.
  repeatdelay	See repeatinterval, below.
  repeatinterval	Normally, a button fires only once when the user releases the mouse button. If you want the button to fire at regular intervals as long as the mouse button is held down, set this option to a number of milliseconds to be used between repeats, and set the repeatdelay to the number of milliseconds to wait before starting to repeat. For example, if you specify “ repeatdelay=500, repeatinterval=100 ” the button will fire after half a second, and every tenth of a second thereafter, until the user releases the mouse button. If the user does not hold the mouse button down at least repeatdelay milliseconds, the button will fire normally.
  state	Set this option to "disabled" to gray out the button and make it unresponsive. Has the value "active" when the mouse is over it. Keep the button pressed with "pressed". Default is "normal".
  takefocus	Normally, keyboard focus does visit buttons, and a space character acts as the same as a mouse click, “pushing” the button. You can set the takefocus option to zero to prevent focus from visiting the button.
  text	Text displayed on the button. Use internal newlines to display multiple text lines.
  textvariable	An instance of StringVar() that is associated with the text on this button. If the variable is changed, the new value will be displayed on the button.
  width	The width of the button. The size is given in pixels for both text and images.

• Methods on Button objects:

  Methods	Description
  .invoke()	Calls the button's command callback, and returns what that function returns. Has no effect if the button is disabled or there is no callback.

• Example:

  from tkinter import Tk
  from tkmacosx import Button
  
  root = Tk()
  root.geometry('200x150')
  B0 = Button(root, text='Button')

CircleButton Widget

BETA-Disclaimer: Please note that this is a BETA version. Issues can be reported here.

Circle shaped tkinter Button can contain text or images, and you can associate a Python function or method with each button. There is a blue focus ring that tells if the button has the focus or not to disable or hide the focus ring, either set takefocus=0 or focuscolor=''. The CircleButton widget supports all the configurable options of tkmacosx Button.

• Configurable options for a button widget. Syntax: CircleButton(root, options=value, ...) All the options are pretty much the same as tkmacosx Button. Other options:

  Options	Description
  radius	Set the size of the button using radius (in pixels). If width or height are given then radius value gets cancelled out.

• Methods on CircleButton objects:

  Methods	Description
  .invoke()	Calls the button's command callback, and returns what that function returns. Has no effect if the button is disabled or there is no callback.

• Example:

from tkinter import *
from tkmacosx import CircleButton

root = Tk()
B0 = CircleButton(root, text='Button')
B0.grid(row=0)
B1 = CircleButton(root, text='Button', bg='#ADEFD1',
            fg='#00203F', borderless=1)
B1.grid(row=0, column=1)
B2 = CircleButton(root, text='Button', bg='#E69A8D',
            fg='#5F4B8B', borderless=1,
            activebackground=('#AE0E36', '#D32E5E'),
            activeforeground='#E69A8D')
B2.grid(row=0, column=2)
root.mainloop()

SFrame Widget

The tkmacosx SFrame widget is just like a tkinter Frame but can be vertically scrolled. The SFrame supports intelligent mousewheel scrolling where it let you use mousewheel with other children widgets also having mousewheel scrolling without interfering with other widgets scrolling, a list of widgets having mousewheel scrolling can be passed to avoidmousewheel argument (ex: avoidmousewheel=(text1, text2, sframe) or just one avoidmousewheel=text2).

• Configurable options for a sframe widget. Syntax: SFrame(root, options=value, ...)

  Options	Description
  avoidmousewheel	Give widgets that also having the mousewheel scrolling and is a child of SFrame, this option will configure widgets to support their mousewheel scrolling as well and not interfere with SFrame mousewheel scrolling. For example: Text widget inside SFrame can have mousewheel scrolling as well as SFrame.
  autohidescrollbar	Auto hides the scrollbar when not in use or when the cursor is not around the scrollbar location. The scrollbar will reappear when mousewheel scrolling is used or the cursor is moved over the scrollbar location. Default is False.
  autohidescrollbardelay	Time taken for the scrollbar to hide after reappearing.
  bg or background	The frame's background color.
  bd or borderwidth	Width of the frame's border. The default is 0 (no border).
  cursor	The cursor used when the mouse is within the frame widget.
  height	The vertical dimension of the new frame. This will be ignored unless you also call .grid_propagate(0) on the frame.
  highlightbackground	Color of the focus highlight when the frame does not have focus.
  highlightcolor	Color is shown in the focus highlight when the frame has the focus.
  highlightthickness	The thickness of the focus highlight.
  mousewheel	Set mousewheel scrolling. The default is False
  padx	Normally, a Frame fits tightly around its contents. To add N pixels of horizontal space inside the frame, set padx=N.
  pady	Used to add vertical space inside a frame. See padx above.
  relief	The default relief for a frame is tk.FLAT, which means the frame will blend in with its surroundings. To put a border around a frame, set its borderwidth to a positive value and set its relief to one of the standard relief types.
  scrollbarwidth	Set the width of scrollbar.
  takefocus	Normally, frame widgets are not visited by input focus. However, you can set takefocus=1 if you want the frame to receive keyboard input. To handle such input, you will need to create bindings for keyboard events.
  width	The horizontal dimension of the new frame. This value be ignored unless you also call .grid_propagate(0) on the frame

• Example:

  from tkinter import *
  from tkmacosx import SFrame, Button
  
  root = Tk()
  root.geometry('350x300')
  frame = SFrame(root, bg='#333')
  text = Text(frame, background='#5F4B8B',
              width=35, height=10, foreground='white')
  text.pack(pady=(0,20))
  
  frame2 = SFrame(frame, bg='#E69A8D', scrollbarwidth=3)
  frame2.pack(pady=20)
  
  frame.config(avoidmousewheel=(text, frame2))
  frame.pack(expand=1, fill='both')
  for i in range(50):
     Button(frame2, text='Button %s'%i).pack()
     text.insert('end', 'Text Line: %s\n'%i)
  
  root.mainloop()

Radiobutton Widget

Radiobutton of tkmacosx are fixed from multiple issues i.e. background color not showing properly when indicator=0, activebackground, activeforeground options not working, few other issues are fixed in tkmacosx Radiobutton. Radiobuttons are sets of related widgets that allow the user to select only one of a set of choices. Each radiobutton consists of two parts, the indicator and the label.

• Configurable options for a Colorscale widget. Syntax: Radiobutton(root, options=value, ...)

  Options	Description
  activebackground	The background color when the mouse is over the radiobutton.
  activeforeground	The foreground color when the mouse is over the radiobutton.
  anchor	If the widget inhabits a space larger than it needs, this option specifies where the radiobutton will sit in that space. The default is anchor=tk.CENTER. For other positioning options. For example, if you set anchor=tk.NE, the radiobutton will be placed in the top right corner of the available space.
  bg or background	The normal background color behind the indicator and label.
  bitmap	To display a monochrome image on a radiobutton, set this option to a bitmap.
  bd or borderwidth	The size of the border around the indicator part itself. Default is two pixels.
  command	A procedure to be called every time the user changes the state of this radiobutton.
  compound	If you specify both text and a graphic (either a bitmap or an image), this option specifies where the graphic appears relative to the text. Possible values are tk.NONE (the default value), tk.TOP, tk.BOTTOM, tk.LEFT, tk.RIGHT, and tk.CENTER. For example, compound=tk.BOTTOM would position the graphic below the text. If you specify compound=tk.NONE, the graphic is displayed but the text (if any) is not.
  cursor	If you set this option to a cursor name, the mouse cursor will change to that pattern when it is over the radiobutton.
  disabledforeground	The foreground color used to render the text of a disabled radiobutton. The default is a stippled version of the default foreground color.
  font	The font used for the text.
  fg or foreground	The color used to render the text.
  height	The number of lines (not pixels) of text on the radiobutton. Default is 1.
  highlightbackground	The color of the focus highlight when the radiobutton does not have focus.
  highlightcolor	The color of the focus highlight when the radiobutton has the focus.
  highlightthickness	The thickness of the focus highlight. Default is 1. Set highlightthickness=0 to suppress the display of the focus highlight.
  image	To display a graphic image instead of text for this radiobutton, set this option to an image object. The image appears when the radiobutton is not selected; compare selectimage, below.
  inidicatoron	Normally a radiobutton displays its indicator. If you set this option to zero, the indicator disappears, and the entire widget becomes a “push-push” button that looks raised when it is cleared and sunken when it is set. You may want to increase the borderwidth value to make it easier to see the state of such a control.
  justify	If the text contains multiple lines, this option controls how the text is justified: tk.CENTER (the default), tk.LEFT, or tk.RIGHT.
  offrelief	If you suppress the indicator by asserting indicatoron=False, the offrelief option specifies the relief style to be displayed when the radiobutton is not selected. The default values is tk.RAISED.
  overrelief	Specifies the relief style to be displayed when the mouse is over the radiobutton.
  padx	How much space to leave to the left and right of the radiobutton and text. Default is 1.
  pady	How much space to leave above and below the radiobutton and text. Default is 1.
  relief	By default, a radiobutton will have tk.FLAT relief, so it doesn't stand out from its background. You can also use relief=tk.SOLID, which displays a solid black frame around the radiobutton.
  selectcolor	The color of the radiobutton when it is set. Default is red.
  selectimage	If you are using the image option to display a graphic instead of text when the radiobutton is cleared, you can set the selectimage option to a different image that will be displayed when the radiobutton is set.
  state	The default is state=tk.NORMAL, but you can set state=tk.DISABLED to gray out the control and make it unresponsive. If the cursor is currently over the radiobutton, the state is tk.ACTIVE.
  takefocus	By default, the input focus will pass through a radiobutton. If you set takefocus=0, focus will not visit this radiobutton.
  text	The label displayed next to the radiobutton. Use newlines ('\n') to display multiple lines of text.
  textvariable	If you need to change the label on a radiobutton during execution, create a StringVar to manage the current value, and set this option to that control variable. Whenever the control variable's value changes, the radiobutton's annotation will automatically change to that text as well.
  underline	With the default value of -1, none of the characters of the text label are underlined. Set this option to the index of a character in the text (counting from zero) to underline that character.
  value	When a radiobutton is turned on by the user, its control variable is set to its current valueoption. If the control variable is an IntVar, give each radiobutton in the group a different integer value option. If the control variable is a StringVar, give each radiobutton a different string value option.
  variable	The control variable that this radiobutton shares with the other radiobuttons in the group. This can be either an IntVar or a StringVar.
  width	The default width of a radiobutton is determined by the size of the displayed image or text. You can set this option to a number of characters ( not pixels) and the radiobutton will always have room for that many characters.
  wraplength	Normally, lines are not wrapped. You can set this option to a number of characters and all lines will be broken into pieces no longer than that number.

• Methods on Radiobutton widget objects:

  Methods	Description
  .deselect()	Clears (turns off) the radiobutton.
  .flash()	Flashes the radiobutton a few times between its active and normal colors, but leaves it the way it started.
  .invoke()	You can call this method to get the same actions that would occur if the user clicked on the radiobutton to change its state.
  .select()	Sets (turns on) the radiobutton.

• Example:

  import tkinter as tk
  import tkmacosx as tkm
  
  root = tk.Tk()
  var = tk.IntVar()
  
  r1 = tkm.Radiobutton(root, text='Radiobutton1', value=1,
                       variable=var, indicatoron=0, padx=20)
  r2 = tkm.Radiobutton(root, text='Radiobutton2', value=2,
                       variable=var, indicatoron=0, padx=20)

ColorVar Variable

ColorVar of tkmacosx set same color to each widget it is assigned to. As ColorVar is a tkinter variable wrapper so it will change the color of widgets whenever the change is made to ColorVar instances. ColorVar takes HEX values and all the color names which tkinter supports but the get() method returns only the HEX value. It will work with all of the following keyword arguments of different widgets (eg:- Canvas, Frame, Button, Label, Canvas items, ...). 'fg', 'foreground', 'bg', 'background', 'activebackground', 'activeforeground', 'disabledforeground', 'highlightbackground', 'highlightcolor', 'selectforeground', 'readonlybackground', 'selectbackground', 'insertbackground', 'disabledbackground', 'activefill', 'activeoutline', 'disabledfill','disabledoutline', 'fill', 'outline' (might work with more but have not tested).

• Configurable options for a ColorVar variable. Syntax: ColorVar(root, options=value, ...)

  Options	Description
  value	The value is an optional value (defaults to "").
  name	The name is an optional Tcl name (defaults to PYVARnum). If _name matches an existing variable and value is omitted then the existing value is retained.

• Methods on ColorVar variable objects:

  Methods	Description
  .get()	Returns the current value of the variable.
  .set(value: str)	Changes the current value of the variable. If any widget options are slaved to this variable, those widgets will be updated when the main loop next idles.

• Example:

  from tkinter import Tk, Label
  from tkmacosx import ColorVar, Button, gradient
  
  root = Tk()
  root['bg'] = '#333'

DictVar Variable

DictVar of tkmacosx stores python dictionary. It is very similar to tkinter StringVar with few modifications to it. DictVar.get() returns an instance of dict type whereas StringVar returns str type also DictVar method get() is a bit different get(key=None, d=None) get a key from get() method if key=None it will return the complete dictionary.

• Configurable options for a DictVar variable. Syntax: DictVar(root, options=value, ...)

  Options	Description
  value	The value is an optional value (defaults to {}).
  name	The name is an optional Tcl name (defaults to PYVARnum). If _name matches an existing variable and value is omitted then the existing value is retained.

• Methods on DictVar variable objects:

  Methods	Description
  .get(key: any=None, d: any=None)	Returns the current value of the variable. To get a specific value of dictionary use key, give a default value to d if the key is not available.
  set(value: str)	Changes the current value of the variable. If any widget options are slaved to this variable, those widgets will be updated when the main loop next idles.

• Example:

  from tkinter import *
  from tkmacosx import DictVar
  
  root = Tk()
  dictionary = DictVar(value = {'width': 100, 'height': 200})
  
  print(type(dictionary.get()))
  print(dictionary.get())
  print(dictionary.get('width'))

SaveVar

SaveVar of tkmacosx will let you save and load values of tkinter variables (StringVar, IntVar, ..). SaveVar uses pickle module to save values of variables into a file and when the program is executed next time, it will load the same values as they were last time. If the content of the .py file changes, it might not load correct values to the assigned variables. To avoid this issue use name argument to refer to the exact assigned values later.

• Configurable options for a SaveVar function. Syntax: SaveVar(var, master=None, value=None, name=None, filename='data.pkl')

  Parameters	Description
  var	Give the tkinter.Variable class like (tk.StringVar, tk.IntVar)
  master	Parent widget.
  value	The value is an optional value (Given variable's default value).
  name	Set a name to group variables or to refer to assigned value when loaded.
  filename	Set the name of the save file. (To make the file invisible in the directory start the name of the file with "." like ".cache-savevar")

• Example:

  from tkinter import *
  from tkmacosx import SaveVar
  
  root = Tk()
  var1 = SaveVar(StringVar, root, 'Enter Username', 'Var1', '.cache-savevar')
  var2 = SaveVar(StringVar, root, 'Enter Password', 'Var2', '.cache-savevar')
  Entry(root, textvariable=var1).pack()
  Entry(root, textvariable=var2).pack()
  root.mainloop()
