Install4j 6.1.6组合框配置：Windows认证选项系统显示控制问询

Absolutely, you can set up a conditional visibility rule for the Windows Authentication option in your combo box to only show up on Windows systems—here's how to make it work with Installer 6.1.6:

1. Leverage Installer's Built-in OS Detection #

Installer 6.1.6 includes system properties that let you check the underlying operating system. The key property here is System.OSFamily (or System.OSName if that's what your installer version uses). This property returns values like Windows for Windows systems, and Linux/Unix for non-Windows environments.

2. Build the Combo Box with Both Options #

First, add your configuration form's combo box component with two list items:

• SQL Server Authentication (visible on all OSes)
• Windows Authentication (to be hidden on Linux)

3. Apply the Visibility Condition #

For the Windows Authentication list item, set a conditional expression using the installer's native expression language. The syntax should look like this:

System.OSFamily = "Windows"

This rule tells the installer to only render the Windows Authentication option when the OS is Windows. Linux users won't see this option at all, which aligns with your requirement.

4. Validate Across Platforms #

• Windows test: Confirm both authentication options appear in the combo box.
• Linux test: Verify only the SQL Server Authentication option is visible.

Quick Notes #

• If System.OSFamily doesn't work for your installer version, check the 6.1.6 docs for alternative OS properties (some versions use System.OSName which returns full OS strings like "Windows 11" or "Ubuntu 22.04").
• Ensure any Windows-specific form fields (like domain/username auto-fill) are also set to follow the same OS condition to avoid broken UI states on Linux.
