select_input()

Open a file chooser dialog to select a file for input.

Examples

def file_selected(selection):
    if selection is None:
        py5.println("Window was closed or the user hit cancel.")
    else:
        py5.println("User selected " + selection)


def setup():
    py5.select_input("Select a file to process:", file_selected)

Description

Open a file chooser dialog to select a file for input. After the selection is made, the selected File will be passed to the callback function. If the dialog is closed or canceled, None will be sent to the function, so that the program is not waiting for additional input. The callback is necessary because of how threading works.

This method has some platform specific quirks. On macOS, this does not work when the Sketch is run through a Jupyter notebook. On Windows, Sketches using the OpenGL renderers (P2D or P3D) will be minimized while the select dialog box is open. This method only uses native dialog boxes on macOS.

Underlying Processing method: selectInput

    prompt: str,  # text prompt for select dialog box
    callback: Callable,  # callback function after selection is made
    default_file: str = None,  # default output file
