74. Settings

PyAero keeps its runtime behavior in a small set of plain-text configuration files. The most important locations are:

• config/config.ini

• resources/Shortcuts/shortcuts.json

• config/shortcuts_user.json

75. Main Runtime Settings

Most application settings live in config/config.ini.

Important sections include:

[Paths]

Controls the data directory, airfoil library root, output folder, and log folder.

[Application]

Controls the predefined airfoil, decimal separator, and exit behavior.

[Window]

Controls the startup window mode and the three configurable window-size presets.

[Graphics]

Controls marker size, zoom anchoring, zoom limits, rubber-band threshold, and view style.

[Magnifier]

Controls the built-in magnifier size and magnification.

[Dialogs]

Defines the default file filters used by dialogs.

[Logging]

Controls message coloring and related behavior.

The settings editor in the GUI exposes these same groups in an editable dialog, which is useful when you want to inspect or adjust advanced values without opening the INI file directly.

76. Airfoil Paths

Two settings matter most for everyday use:

• AIRFOILS defines the root of the airfoil library

• DEFAULT_AIRFOIL defines what is loaded by the predefined-airfoil action

The local airfoil library is managed automatically below the configured airfoil root.

77. Keyboard Shortcuts

PyAero’s shortcut system is registry-driven.

• Built-in defaults live in resources/Shortcuts/shortcuts.json

• User overrides are stored in config/shortcuts_user.json

The shortcut editor in the GUI reads and writes these same definitions, so manual edits and GUI edits stay aligned.

78. Menus and Toolbar

Menus and toolbar content are assembled from layout data under resources/Menus/ while actions themselves are defined centrally in src/ActionRegistry.py.

This split keeps three things clean:

• the UI layout

• the action definitions

• the shortcut bindings

79. Maintenance Dialogs

Two additional dialogs help with UI maintenance and general reference work:

• Icon Preview shows the semantic icons and bundled app artwork used across the interface

• About PyAero summarizes the application, licensing, and environment details

Icon preview dialog for checking semantic icons and bundled assets.

About dialog with project, license, and environment information.

80. Launch Location

PyAero should be started from the repository root. The application expects bundled resources such as menus, icons, and airfoil data to resolve relative to that location.

81. Window Presets

The View menu now contains a Window Size submenu with:

• a cycle action

• preset 1

• preset 2

• preset 3

The presets are configured in config/config.ini as x, y, width, height tuples. The startup mode can either be maximized or one of the preset entries.
