1.文本输入使用TextInput组件可以创建一个文本输入框，以便用户可以输入文本。以下是创建一个TextInput组件的代码：import togadef text_input_handler(widget): print(widget.value) def build(app): text_input = toga.TextInput(on_change=text_input_handler) return toga.MainWindow(title=app.name, size=(640, 480)).with_content( toga.Box(children=[text_input], style=Pack(direction=COLUMN, padding=50)) )if __name__ == '__main__': app = toga.App('My Text Input App') app.startup = build app.main_loop()2.图片可以使用ImageView组件显示图像。以下是显示图像的代码：import togadef build(app): image_path = '<path_to_image_file>' image_view = toga.ImageView(image_path) return toga.MainWindow(title=app.name, size=(640, 480)).with_content( toga.Box(children=[image_view], style=Pack(direction=COLUMN, padding=50)) )if __name__ == '__main__': app = toga.App('My Image App') app.startup = build app.main_loop()
