dataexploreruser/autoscroll

Automatically scrolling logger window for Dear PyGui that meets the following requirements.

• Regularly update
• Scrollable
• Ability to automatically scroll to newest entry
• Ability to show and hide the log with a toggle button
• Text should be selectable
• Automatic scrolling can be turned on and off

Note

The code provided in autoscroll.py runs perfectly fine by itself. However, if you just process your log file directly with textwrap.fill you will get some very strange line breaking because it doesn't preserve the existing line breaks in the file, so you need to wrap each line individually and then join them with a newline. This is illustrated in the code below.

    def update_log_display(self):
        FRAME_PADDING = 3
        log_contents = self.read_log_file("latest.log")
        lines = log_contents.splitlines()

        wrapped_lines = [textwrap.fill(line, width=128, replace_whitespace=False) for line in lines]
        wrapped_log = "\n".join(wrapped_lines)

        if wrapped_log:
            dpg.set_item_height(self.log_text, dpg.get_text_size(wrapped_log)[1] + (2 * FRAME_PADDING))
            dpg.set_value(self.log_text, wrapped_log)
        if self.log_autoscroll:
            dpg.configure_item(self.log_text, tracked=True)
        else:
            dpg.configure_item(self.log_text, tracked=False)
