Description of Options

  • label: The format string for the CPU usage label. You can use placeholders like {info[percent][total]} to dynamically insert CPU information.
  • label_alt: The alternative format string for the CPU usage label. Useful for displaying additional CPU details.
  • class_name: Additional CSS class name for the widget. This allows for custom styling.
  • update_interval: The interval in milliseconds at which the widget updates its information. Minimum is 1000 ms (1 second).
  • cpu_thresholds: A dictionary specifying the thresholds for CPU usage levels. The keys are low, medium, and high, and the values are the percentage thresholds.
  • hide_decimal: Whether to hide decimal places in the CPU widget.
  • histogram_icons: A list of icons representing different levels of CPU usage in the histogram. 8 icons are typically used, representing usage from 0% to 80%+.
  • histogram_num_columns: The number of columns to display in the CPU usage histogram.
  • callbacks: A dictionary specifying the callbacks for mouse events. The keys are on_left, on_middle, and on_right, and the values are the names of the callback functions.
  • animation: A dictionary specifying the animation settings for the widget. It contains three keys: enabled, type, and duration. The type can be fadeInOut and the duration is the animation duration in milliseconds.
  • container_shadow: Container shadow options.
  • label_shadow: Label shadow options.
  • progress_bar: A dictionary containing settings for the progress bar. It includes:
  • enabled: Whether the progress bar is enabled.
  • position: The position of the progress bar, either "left" or "right".
  • size: The size of the progress bar.
  • thickness: The thickness of the progress bar.
  • color: The color of the progress bar. Color can be single color or gradient. For example, color: "#57948a" or color: ["#57948a", "#ff0000"]" for a gradient.
  • background_color: The background color of the progress bar.
  • animation: Whether to enable smooth change of the progress bar value.
  • menu: Configuration for the popup menu that displays a usage graph and detailed CPU statistics. It includes:
  • enabled: Whether the popup menu is enabled. Default: false.
  • blur: Whether to apply a blur effect to the popup background. Default: true.
  • round_corners: Whether the popup has rounded corners. Default: true.
  • round_corners_type: The type of rounded corners, either "normal" or "small". Default: "normal".
  • border_color: The border color of the popup. Default: "System".
  • alignment: Horizontal alignment of the popup relative to the widget: "left", "center", or "right". Default: "right".
  • direction: Whether the popup opens "up" or "down". Default: "down".
  • offset_top: Vertical offset in pixels from the widget. Default: 6.
  • offset_left: Horizontal offset in pixels from the widget. Default: 0.
  • show_graph: Whether to show the usage history graph. Default: true.
  • show_graph_grid: Whether to display a square grid overlay on the graph. Default: false.
  • graph_history_size: Number of data points to keep in the graph history. Must be between 10 and 180. Default: 60.
  • pin_icon: Icon displayed on the pin button when the popup is unpinned. Default: "\ue718".
  • unpin_icon: Icon displayed on the pin button when the popup is pinned. Default: "\ue77a".

Available Placeholders

Core Information

  • {info[cores][physical]} - Number of physical CPU cores
  • {info[cores][total]} - Total number of CPU cores (including logical/hyperthreaded cores)

Frequency Information

  • {info[freq][current]} - Current CPU frequency in MHz (includes turbo boost, matches Windows Task Manager)
  • {info[freq][max]} - Base/nominal CPU frequency in MHz

Usage Percentages

  • {info[percent][total]} - Total CPU usage percentage (0-100)
  • {info[percent][core]} - List of per-core CPU usage percentages

Histograms

  • {info[histograms][cpu_freq]} - CPU frequency histogram using configured icons
  • {info[histograms][cpu_percent]} - CPU percentage histogram using configured icons
  • {info[histograms][cores]} - Per-core usage histogram using configured icons

Note: The CPU widget uses Windows Performance Data Helper (PDH) API for accurate real-time metrics. If PDH counters are corrupted, the widget will display default values. To repair broken PDH counters, run lodctr /r as Administrator.
