Autoconfig allows you to edit any Go struct with a Qt interface based on MIQT.

type Foo struct {                []----------------------[]
    Name string                  |  Name:  [___________]  |
}                                |                [Save]  |
                                 []----------------------[]

Creating a dialog:

// Passed in struct should be a pointer value
var foo MyStruct
autoconfig.OpenDialog(&foo, nil, "Dialog title", func() {
	// The value of 'foo' has been updated
})

Embedding into an existing layout:

var foo MyStruct
saveCallback := autoconfig.MakeConfigArea(&foo, qt6.QFormLayout)

// To save changes from the GUI into the struct, call the saveCallback() function.
// However, warning that nested fields may be mutated automatically without calling.

Only public fields are supported. This is a limitation of the standard library reflect package.

• All Go primitive types
  • string
  • bool
  • int
    • including uintptr, uint, and fixed-width versions
    • A custom QSpinBox is implemented for large bit-width types
  • float
  • complex
  • pointer (optional)
    • struct tags on the pointer are passed in to the child renderer
    • supports Resetter interface to allow resetting to default values
  • slice
  • []byte
    • supports MIME content detection, multiline text editor, and importing and exporting file content
  • fixed-size array
  • map
  • struct
    • child structs by value, and embedded structs, are rendered inline
    • struct tags on the slice are passed in to each child renderer
  • empty struct
• Standard library types
  • time.Time
• Custom types
  • AddressPort
  • EnumList
  • ExistingDirectory
  • ExistingFile
  • Header
  • MultilineString
  • Password
  • Any custom type that implements the Renderer interface
• Custom layouts
  • OneOf
  • TabGroup

Add struct tags to individual fields to customize the rendering:

Implement these interfaces to customize the rendering:

2026-01-16 v0.6.0

• Pointers: Allow resetting any pointer type that implements Resetter
• Allow scrolling tall dialog boxes
• Render "xxDir" string struct fields as if they were ExistingDirectory
• Render "xxPass", "xxPassword" string struct fields as if they were Password
• Fix overflow for int64 and uint32/64 by implementing custom QSpinBox

2026-01-04 v0.5.0

• Support map
• Support fixed-size arrays
• Support []byte with special handling, including MIME content detection and file import/export
• Support complex64 and complex128
• Add TabGroup
• Add yprefix and ysuffix support for int, uint, and float types
• Labels: Hide standalone : if a blank label was used
• Labels: Hide duplicate labels if text was already shown in dialog/tab/dropdown
• Fix label formatting for strings
• Show "" as the label formatting for the empty string

2025-12-03 v0.4.1

• Reduce flicker on Windows by enforcing Qt parent relationship during creation

2025-12-03 v0.4.0

• Reduce flicker on Windows by setting Qt UpdatesEnabled false during struct calculation
• OneOf: support Reset()
• Labels: Support String() on ExistingFile and ExistingDirectory
• Labels: Support labels on pointer types, with parenthesis
• Labels: Support labels on structs using OneOf
• Labels: Automatically convert CamelCase struct names to separated words
• Struct tags are now passed through to slice and pointer children (e.g. allowing yfilter on *ExistingFile)
• Use accurate type comparison for time.Time and OneOf, in case of naming conflict in other packages

2025-11-26 v0.3.0

• BREAKING: Rename InitDefaulter to Resetter, rename Autoconfiger to Renderer
• Add OneOf
• Renderer interface now supports being implemented on either value or pointer receiver
• AddressPort now renders a string description when used in a slice

2025-11-17 v0.2.0

• Support arbitrary pointers, slices, int, uintptr, float, time.Time
• Add Header
• Skip over unsupported types (func, interface, unsafe.Pointer)
• Fix cosmetic inconsistency when editing types

2025-11-15 v0.1.0

• Initial public release
