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')
B0.pack(padx=20, pady=(20,0))
B1 = Button(root, text='Button', bg='#ADEFD1',
fg='#00203F', borderless=1)
B1.pack(padx=20, pady=10)
B2 = Button(root, text='Button', bg='#E69A8D',
fg='#5F4B8B', borderless=1,
activebackground=('#AE0E36', '#D32E5E'),
activeforeground='#E69A8D')

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:

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',

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.

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',

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

r2.pack(padx=10)
r3.pack(pady=10)

root.mainloop()







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).

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()
