6.6.0-dev (?)

Thank you to everyone who has already purchased a commercial license! Your support is very important to our ongoing development.

Setup and Uninstall now both support dark mode, forced or automatic. Custom styles are also supported.

This new feature does not increase the size of Setup if not used and is fully backward compatible.

• Enhanced [Setup] section directive WizardStyle with new appearance modes:
  • Added appearance modes: light (default, forced light mode, same appearance as previous versions), dark (forced dark mode, new appearance), and dynamic (automatically follows Windows system settings).
  • For example, to use the modern style and automatically switch between light and dark appearance based on the user's Windows system settings:

    WizardStyle=modern dynamic

  • Dark mode automatically replaces icons, wizard images, and adjusts colors while maintaining a consistent user experience. It still allows a custom main icon, and custom images and colors. Includes support for styled task dialogs.
    Example screenshot of Setup using the built-in dark style, at 175% DPI.

    Includes full right to left support.
  • See the updated WizardStyle help topic for more information and special considerations.
• Added four new DynamicDark directives to the [Setup] section, for specifying separate custom images and colors used specifically when dynamic mode switches to dark appearance.
• For example, to specify two custom colors, one for light mode and one for dark mode:

  WizardStyle=modern dynamic
  WizardImageBackColor=clWhite
  WizardImageBackColorDynamicDark=#2b2b2b

  Note: Forced dark mode (dark) does not use the DynamicDark settings; it uses the standard settings. Example:

  WizardStyle=modern dark
  WizardImageBackColor=#2b2b2b

• The default style can be customized by specifying a VCL Styles file using the new WizardStyleFile directive and a fifth DynamicDark directive.
  
  • For example, to specify two custom styles, one for light mode and one for dark mode:

    WizardStyle=modern dynamic
    WizardStyleFile=MyStyleLight.vsf
    WizardStyleFileDynamicDark=MyStyleDark.vsf

    Example screenshot of Setup using the Polar Light style, at 175% DPI.

    Example screenshot of a task dialog using the Zircon style, at 125% DPI.
  • When forced light (light) or dynamic dark (dynamic with Windows in light mode) is active, the default style is the system's native light style. Otherwise, the default style is a built-in custom dark style.
  • When a custom style (including the built-in custom dark style) is active, all text labels, except for the label associated with the BeveledLabel message, are transparent rather than opaque.
  • The Polar style shown above is available built-in and directly supported by the WizardStyle directive. For example:

    WizardStyle=modern dynamic polar

  • Two more custom styles are available built-in and directly supported by the WizardStyle directive: slate and zircon. slate uses medium gray for both the light and dark appearances, and zircon is an alternative light-only style, shown above. For example:

    WizardStyle=modern zircon

• Compiler IDE: Added a new Wizard Style page to the New Script Wizard, allowing to choose a style and view example screenshots.
• Pascal Scripting: Add new support functions IsWinDark and IsDarkInstallMode.

• [Setup] section directive WizardImageBackColor and the other three BackColor directives now accept the #rrggbb color format in addition to $bbggrr.
• Pascal Scripting: Added support for command link buttons (the button style used in task dialogs). See CodeClasses.iss for an example.
