# Recipes
These are examples of how you can use `guizero` to create user interfaces. Don't be restricted to these ideas, check out [Using guizero](start.md) and the [widgets](app.md).
## Hello World
Create a guizero app and display some text.
```python
from guizero import App, Text
app = App()
text = Text(app, text="hello world")
app.display()
```
## Get some text
Get some data from the user using a `TextBox`.
```python
from guizero import App, TextBox
app = App()
name = TextBox(app, text="Enter your name")
app.display()
```
## Push a button
Use a `PushButton` to display a message when the button is pressed.
```python
from guizero import App, TextBox, PushButton, Text
def update_text():
label.value = name.value
app = App()
label = Text(app, text="What's your name?")
name = TextBox(app)
button = PushButton(app, command=update_text)
app.display()
```
## Display an image
Use a `Picture` object to display an image.
```python
from guizero import App, Picture
app = App()
pic = Picture(app, image="myimage.gif")
app.display()
```
## Toggle 2 buttons
Have 2 buttons, **start** and **stop** with them changing the `enabled` state of each other.
```python
from guizero import App, PushButton
def start():
start_button.disable()
stop_button.enable()
def stop():
start_button.enable()
stop_button.disable()
app = App()
start_button = PushButton(app, command=start, text="start")
stop_button = PushButton(app, command=stop, text="stop", enabled=False)
app.display()
```
## Change your apps appearance
Your app doesn't have to use the standard colors and text, let your user pick the background and text color from 2 combo's.
```python
from guizero import App, Combo, Text
def update_bg():
app.bg = bg_combo.value
def update_text():
app.text_color = text_combo.value
colors = ["black", "white", "red", "green", "blue"]
app = App()
app.bg = "black"
app.text_color = "white"
title1 = Text(app, text="Background color")
bg_combo = Combo(app, options=colors, selected=app.bg, command=update_bg)
title2 = Text(app, text="Text color")
text_combo = Combo(app, options=colors, selected=app.text_color, command=update_text)
app.display()
```
## Scale an image
Display an image on the screen with 2 sliders, 1 for height and 1 for width.
```python
from guizero import App, Slider, Picture
def resize():
picture.width = width.value
picture.height = height.value
app = App(layout="grid")
picture = Picture(app, image="image.gif", grid=[0,1])
width = Slider(app, command=resize, grid=[0,0], start=1, end=picture.width)
width.width = picture.width
width.value = picture.width
height = Slider(app, command=resize, horizontal=False, grid=[1,1], start=1, end=picture.height)
height.height = picture.height
height.value = picture.height
app.display()
```
## Double click a widget
To be able to react when a user double click's you will need to use [events](events.md).
```python
from guizero import App, Text
def double_click():
double_click_me.value = "Thanks"
app = App()
double_click_me = Text(app, text="Double click me")
double_click_me.when_double_clicked = double_click
app.display()
```
