Sizes

You can set the width and height of widgets in guizero.

Widgets are sized by either pixels or characters depending on the widget and what it contains.

Some widgets size can also be set to "fill" where it will use up all of the available space.

from guizero import App, PushButton, Slider, ListBox

app = App()

# A PushButton's size is noted in characters
button = PushButton(app, width=30, height=5)

# A Slider's size is noted in pixels
slider = Slider(app, width=300, height=30)

# Some widgets such as ListBox can also be told to fill all the available space
listbox = ListBox(app, width="fill", height="fill")

app.display()
