PushButton

__init__(
    self,
    master,
    command=None,
    args=None,
    text="Button",
    image=None,
    pady=10,
    padx=10,
    grid=None,
    align=None,
    icon=None,
    visible=True,
    enabled=None,
    width=None,
    height=None)

What is it?

The PushButton object displays a button with text or an image, which calls a function when pressed.

How do I make one?

Create a PushButton object like this:

from guizero import App, PushButton
def do_nothing():
    print("Button was pressed")

app = App()
button = PushButton(app, command=do_nothing)
app.display()

Create a picture PushButton with an image like this:

from guizero import App, PushButton
def do_nothing():
    print("A picture button was pressed")

app = App()
button = PushButton(app, image="button.gif", command=do_nothing)
app.display()

Depending on your operating system and whether you installed the guizero additional image features will determine what image types you can use for PushButton. By default GIF and PNG are supported, except macOS which only supports GIF.

Starting parameters

When you create a PushButton object you must specify master and you can specify any of the optional parameters. Specify parameters in the brackets, like this: button = PushButton(app)

Parameter	Takes	Default	Compulsory	Description
master	App, Window or Box	-	Yes	The container to which this widget belongs
command	function name	None	-	The name of a function to call when the button is pressed.
align	string	None	-	Alignment of this widget within its container. Possible values: "top", "bottom", "left", "right".
args	list	None	-	If you wish to pass any arguments to the function specified in the command parameter, you can specify them as a list
grid	List [int, int]	None	-	[x,y] coordinates of this widget. This parameter is only required if the master object has a grid layout.
image	string	None	-	The file path, tkinter.PhotoImage or PIL.Image you wish to display. If both an image and text are specified, the image will override the text.
padx	int	10	-	How much horizontal padding to add between the text/icon and the edge of the button.
pady	int	10	-	How much vertical padding to add between the text/icon and the edge of the button.
text	string	"Button"	-	The text to display on the button
visible	boolean	True	No	If the widget should be visible.
enabled	boolean	None	No	If the widget should be enabled. If None (the default) the enabled property will be inherited from the master
width	size	None	No	Set the width of the widget in characters or pixels if its an image button or to "fill"
height	size	None	No	Set the height of the widget in characters or pixels if its an image button or to "fill"

Methods

You can call the following methods on a PushButton object.

Method	Takes	Returns	Description
after(time, command, args=None)	time (int), command (function name), args (list of arguments)	-	Schedules a single call to command after time milliseconds. (To repeatedly call the same command, use repeat())
cancel(command)	command (function name)	-	Cancels a scheduled call to command
destroy()	-	-	Destroys the widget
disable()	-	-	Disables the widget so that it is "greyed out" and cannot be interacted with
enable()	-	-	Enables the widget
focus()	-	-	Gives focus to the widget
hide()	-	-	Hides the widget from view. This method will unpack the widget from the layout manager.
padding(padx, pady)	padx (int), pady(int)	-	Sets the amount of x (horizontal) and y (vertical) padding between the text/icon and the edge of the button
repeat(time, command, args=None)	time (int), command (function name), args (list of arguments)	-	Repeats command every time milliseconds. This is useful for scheduling a function to be regularly called, for example updating a value read from a sensor.
resize(width, height)	width (int), height (int)	-	Sets the width and height of the widget
show()	-	-	Displays the widget if it was previously hidden
toggle()	-	-	Changes the state of the button to the opposite of its current state - if it is currently enabled, disable it and vice versa.
update_command(command, args =None)	command (function name), args (Optional List of arguments to be passed to command)	-	Updates the function to call when the button is pressed .

Properties

You can set and get the following properties:

Method	Data type	Description
align	string	The alignment of this widget within its container
bg	color	The background colour of the widget
enabled	boolean	True if the widget is enabled
font	string	The font of the text on the button
grid	List	[x,y] coordinates of this widget. This parameter is only required if the master object has a grid
height	size	Set the height of the widget in characters or pixels if its an image button or to "fill"
image	image_source (string)	The file path, tkinter.PhotoImage or PIL.Image you wish to display.
master	App or Box	The container to which this widget belongs
text	string	The text on the button
text_color	color	The colour of the text on the button
text_size	int	The size of the text on the button
text_bold	boolean	Whether the text is bold
text_italic	boolean	Whether the text is italic
text_underline	boolean	Whether the text is underlined
text_overstrike	boolean	Whether the text is overstruck
tk	tkinter.Button	The internal tkinter object, see Using tkinter
value	int	Returns 1 when the button is pressed, 0 if the button is released
visible	boolean	If this widget is visible
width	size	Set the width of the widget in characters or pixels if its an image button or to "fill"

Refer to a property as <name of widget>.property. For example, if your PushButton object is called button you would write button.value.

You can set the property (for example button.bg = "red") or get the value of the property to use (for example print(button.bg)).
