### 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. |

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,

              activeforeground='#E69A8D')
  B2.pack()
  root.mainloop()
  ```

- Few sample of different styles of button that can be configured.

```python
# Options to get button in the first image.
b1 = Button(root, text='Button', activeforeground= '#EE3B3B', overrelief='flat', relief='flat', borderwidth=2,

### CircleButton Widget

**_BETA-Disclaimer:_** _Please note that this is a BETA version. Issues can be reported [here](https://github.com/Saadmairaj/tkmacosx/issues/new/choose)._

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](#button-widget).

- Configurable options for a button widget. Syntax: `CircleButton(root, options=value, ...)`
  All the options are pretty much the same as tkmacosx [Button](#button-widget). 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:

- **Example:**

```python
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:**

```python
  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()
  ```

root = Tk()
  root['bg'] = '#333'
  bgvar = ColorVar(value='#333')
  fgvar = ColorVar(value='white')
  Label(root, text="I am a Label, Hello! :-)",bg=bgvar, fg=fgvar).pack(pady=10)

### 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_.

### 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)._

### 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 PY*VARnum). 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:**

```python
  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:**

```python
  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()
  ```

  | _mode_     | Use mode for more control over the shade of the color. Use `mode='-'` for darker shade, use `mode='+'` for lighter shade, use `mode='auto'` to automatically decide the shade _(the deafult)_.
