Multiple Windows
A guizero application should only have have 1 App object, this is the main window and controller of your program.
If you want to create a 2nd (or 3rd, 4th, 5th) window, your program should use a Window object.
A 2nd Window
Creating a 2nd Window is easy and just like creating a widget you need to pass it the App:
from guizero import App, Window
app = App(title="Main window")
window = Window(app, title="2nd window")
app.display()
Adding widgets to the 2nd window is the same as adding them to an app, by passing the name of the window:
from guizero import App, Window, Text
app = App(title="Main window")
window = Window(app, title="2nd window")
text = Text(window, text="text")
app.display()
Opening and closing windows
When a Window
object is created it is immediately displayed on the screen, you can control it using the show()
and hide()
methods.
To make a window which is shown when a button on the App
is clicked and closed when a button is clicked on the Window
.
from guizero import App, Window
def open_window():
window.show()
def close_window():
window.hide()
app = App(title="Main window")
window = Window(app, title="2nd window")
window.hide()
open_button = PushButton(app, text="Open", command=open_window)
close_button = PushButton(window, text="Close", command=close_window)
app.display()
Modal windows
When a window is opened using show()
it is opening side by side with the main window, and both windows can be used at the same time
To open a "modal" window which prevents the other windows in the applcation being used until it is closed you can pass True
to the optional wait
parameter of show
e.g. window.show(wait=True)
.
This will force all other windows to wait until this window is closed before they can be used.
def open_window():
window.show(wait=True)
