Overview

Package GiV (Cogent Core Views) provides a model / view framework to view Go data using reflection

Views are Widgets that automatically display and interact with standard Go data, including structs, maps, slices, and the primitive data elements (string, int, etc). This implements a form of model / view separation between data and GUI representation thereof, where the models are the Go data elements themselves.

This provides automatic, powerful GUI access to essentially any data in any other Go package. Furthermore, the Value framework allows for easy customization and extension of the GUI representation, based on the classic Go "Stringer"-like interface paradigm -- simply define a Value() method on any type, returning giv.Value that manages the interface between data structures and GUI representations.

See the wiki at: https://cogentcore.org/core/gi/v2/wiki/Views for more extensive docs.

Some of the most important view elements are:

Value

The Value provides a common API for representing values (int, string, etc) in the GUI, and are used by more complex views (StructView, MapView, SliceView, etc) to represents the elements of those data structures.

Do Ctrl+Alt+I in any window to pull up the Inspector which will show you ample examples of the Value interface in action, and also allow you to customize your GUI.

TreeView

The TreeView displays Cogent Core Node Trees, using a standard tree-browser with collapse / open widgets and a menu for typical actions such as adding and deleting child nodes, along with full drag-n-drop and clipboard Copy/Cut/Paste functionality. You can connect to the selection signal to e.g., display a StructView field / property editor of the selected node.

TableView

TableView displays a slice-of-struct as a table with columns as the struct fields and rows as the elements in the struct. You can sort by the column headers and it supports full editing with drag-n-drop etc. If set to ReadOnly, then it serves as a chooser, as in the FileView.

FuncButton

Provides GUI for calling methods, prompting the user for any args, using the Value system. The gti tool can capture comment data to provide tooltips for users: specify //gti:add for types and methods that are called. Much of your toolbar and menu level GUI can be implemented in this system. See gi/settings.go and giv/settingsview.go for how the Cogent Core Prefs dialog is implemented, and see the Cogent Code project for a more complex case.

var NoSentenceCaseFor []string

NoSentenceCaseFor indicates to not transform field names in [StructView]s into "Sentence case" for types whose full, package-path-qualified name contains any of these strings. For example, this can be used to disable sentence casing for types with scientific abbreviations in field names, which are more readable when not sentence cased. However, this should not be needed in most circumstances.

var ValueMap map[string]ValueFunc

The ValueMap is used to connect type names with corresponding Value representations of those types -- this can be used when it is not possible to use the Valuer interface (e.g., interface methods can only be defined within the package that defines the type -- so we need this for all types in gi which don't know about giv). You must use laser.LongTypeName (full package name + "." . type name) for the type name, as that is how it will be looked up.

Value is an interface for managing the GUI representation of values (e.g., fields, map values, slice values) in Views (StructView, MapView, etc). It is a GUI version of the reflect.Value, and uses that for representing the underlying Value being represented graphically. The different types of Value are for different Kinds of values (bool, float, etc) -- which can have different Kinds of owners. The ValueBase class supports all the basic fields for managing the owner kinds.

FieldToValue returns the appropriate Value for given field on a struct -- attempts to get the FieldValuer interface, and falls back on ToValue otherwise, using field value (fval) gopy:interface=handle

func NewSoloValue 

func NewSoloValue(val any) Value

NewSoloValue makes and returns a new Value from the given value. It does not configure the widget, so most end-user code should call NewValue instead. It is intended for use in internal code that needs standalone solo values (for example, for a custom TmpSave).

func NewValue 

func NewValue(par ki.Ki, val any, name ...string) Value

NewValue makes and returns a new Value from the given value and creates the widget for it with the given parent and optional name. It is the main way that end-user code should interact with giv. The given value needs to be a pointer for it to be settable.

NewValue is not appropriate for internal code configuring non-solo values (for example, in StructView), but it should be fine for most end-user code.

func ToValue 

func ToValue(it any, tags string) Value

ToValue returns the appropriate Value for given item, based only on its type -- attempts to get the Valuer interface and failing that, falls back on default Kind-based options. tags are optional tags, e.g., from the field in a struct, that control the view properties -- see the gi wiki for details on supported tags -- these are NOT set for the view element, only used for options that affect what kind of view to create. See FieldToValue for version that takes into account the properties of the owner.

	// the object that owns this value, either a struct, slice, or map, if non-nil -- if a Ki Node, then SetField is used to set value, to provide proper updating
	Owner any

	// if Owner is a struct, this is the reflect.StructField associated with the value
	Field *reflect.StructField

	// set of tags that can be set to customize interface for different types of values -- only source for non-structfield values
	Tags map[string]string `set:"-"`

	// if Owner is a map, and this is a value, this is the key for this value in the map
	Key any `set:"-" edit:"-"`

	// if Owner is a map, and this is a value, this is the value view representing the key -- its value has the *current* value of the key, which can be edited
	KeyView Value `set:"-" edit:"-"`

	// if Owner is a slice, this is the index for the value in the slice
	Idx int `set:"-" edit:"-"`

	// type of widget to create -- cached during WidgetType method -- chosen based on the Value type and reflect.Value type -- see Valuer interface
	WidgetTyp *gti.Type `set:"-" edit:"-"`

	// the widget used to display and edit the value in the interface -- this is created for us externally and we cache it during ConfigWidget
	Widget gi.Widget `set:"-" edit:"-"`

	// Listeners are event listener functions for processing events on this widget.
	// type specific Listeners are added in OnInit when the widget is initialized.
	Listeners events.Listeners `set:"-" view:"-"`

	// value view that needs to have SaveTmp called on it whenever a change is made to one of the underlying values -- pass this down to any sub-views created from a parent
	TmpSave Value `set:"-" view:"-"`
}

ValueBase provides the basis for implementations of the Value interface, representing values in the interface -- it implements a generic TextField representation of the string value, and provides the generic fallback for everything that doesn't provide a specific Valuer type.
