FlowPanel

FlowPanel is a Python package for creating a customizable graphical user interface (GUI) using tkinter. It allows users to configure a panel with various types of input fields and execute a function with multithreading support.

Features

• Dynamic Input Fields: Supports multiple input types including entry fields, comboboxes, checkboxes, and listboxes.
• Progress Tracking: Provides a progress bar to indicate ongoing operations.
• Messaging System: Appends messages to a text area with color-coding based on the message type.
• Help Functionality: Opens a help window with support for text and PDF files.
• Multithreading: Runs background tasks without freezing the GUI.
• Customizable GUI: Easily adjust the panel title, descriptions, and input fields.

Installation

To use FlowPanel, you need to have Python 3.x installed on your system. Clone the repository or download the package files.

Install the package locally using:

pip install flow_panel

Usage

Here’s a basic example of how to use the FlowPanel class:

import time
from flow_panel import FlowPanel


def example_run_function(panel: FlowPanel):
    panel.update_progress(0, 10)
    for i in range(10):
        if panel.should_stop or panel.stop_event.is_set():
            panel.append_message("Process stopped by user.")
            break
        time.sleep(1)
        panel.update_progress(i + 1, 10)
        panel.append_message(f"Step pass {i + 1} completed.")
    if not panel.should_stop:
        panel.append_message("Process finished.")


if __name__ == "__main__":
    gui = FlowPanel(
        title_short="Test Panel",
        title_long="Test Panel GUI",
        list_descriptions=["Run a test process", "with multiple steps."],
        list_user_entries=[
            ["Input 1", "entry", True, None],
            ["Input 2", "combobox", False, ["Option 1", "Option 2"]],
            ["Input 3", "checkbox", False, None],
        ],
        run_function=example_run_function,
        help="This is an example help text."
    )
    gui.mainloop()
