Overview

Package gendata contains data used to generate GTK4 bindings for Go. It exists primarily to be used externally.

var ConversionProcessors = []ConversionProcessor{

var DynamicLinkNamespaces = []string{
	"GLib-2",
	"GObject-2",
	"Graphene-1",
	"GdkPixbuf-2",
}

DynamicLinkNamespaces lists namespaces that should be generated directly using Cgo. It includes important core packages as well as packages that are small but performance-sensitive.

var ExtraGoContents = map[string]string{
	"gtk/v3/gtk.go": `
		// Init binds to the gtk_init() function. Argument parsing is not
		// supported.
		func Init() {
			C.gtk_init(nil, nil)
		}
	`,
}

ExtraGoContents contains the contents of files that are appended into generated outputs. It is used to add custom implementations of missing functions.

Filters defines a list of GIR types to be filtered. The map key is the namespace, and the values are list of names.

var GenerateExceptions = []string{
	"cairo-1",
	"Atspi-2",
}

GenerateExceptions contains the keys of the underneath ImportOverrides map.

View Source 
var ImportOverrides = map[string]string{}

ImportOverrides is the list of imports to defer to another library, usually because it's tedious or impossible to generate.

Not included: coreglib (gotk3/gotk3/glib).

var Main = genmain.Data{
	Module:                Module,
	Packages:              Packages,
	ImportOverrides:       ImportOverrides,
	PkgExceptions:         PkgExceptions,
	GenerateExceptions:    GenerateExceptions,

	DynamicLinkNamespaces: DynamicLinkNamespaces,
	SingleFile:            true,
}

Main contains all of gendata's variables as one big genmain.Data value.

This stays ugly just because it's the main gotk4 package with exposed gendata. Don't actually do this; just make a global genmain.Data instead.

View Source 
var Packages = []genmain.Package{
	{Name: "glib-2.0", Namespaces: []string{
		"GLib-2",
		"GObject-2",
		"Gio-2",
	}},
	{Name: "gobject-introspection-1.0", Namespaces: []string{

		"Pango-1",
		"PangoCairo-1",
	}},
	{Name: "gtk4"},
	{Name: "gtk+-3.0"},
}

Packages lists pkg-config packages and optionally the namespaces to be generated. If the list of namespaces is nil, then everything is generated.

View Source 
var PkgExceptions = []string{
	"core",
	"cairo",
	"LICENSE",
}

PkgExceptions contains a list of file names that won't be deleted off of pkg/.

View Source 
var PkgGenerated = []string{
	"atk",

	"gdk",
	"gdkpixbuf",
	"gdkpixdata",
	"gdkwayland",
	"gdkx11",
	"gio",
	"glib",
	"gobject",
	"graphene",
	"gsk",
	"gtk",
	"pango",
	"pangocairo",
}

PkgGenerated contains a list of file names that are packages generated using the given Packages list. It is manually updated.

var Postprocessors = map[string][]girgen.Postprocessor{

Postprocessors is similar to Append, except the caller can mutate the package in a more flexible manner.

Preprocessors defines a list of preprocessors that the main generator will use. It's mostly used for renaming colliding types/identifiers.

Functions

func GLibAliases 

func GLibAliases(nsgen *girgen.NamespaceGenerator) error

GLibAliases generates aliases in the glib/v2 package to the core/glib package. It is generated so that users don't have to import both glib packages.

func GLibDateTime 

func GLibDateTime(nsgen *girgen.NamespaceGenerator) error

GLibDateTime generates NewTimeZoneFromGo and NewDateTimeFromGo.

func GLibLogs 

func GLibLogs(nsgen *girgen.NamespaceGenerator) error

GLibLogs adds the following g_log_* functions:

  • g_log_set_handler
  • g_log_set_handler_full

func GLibObjectComparer 

func GLibObjectComparer(nsgen *girgen.NamespaceGenerator) error

func GLibVariantIter 

func GLibVariantIter(nsgen *girgen.NamespaceGenerator) error

func GdkPixbufFromImage 

func GdkPixbufFromImage(nsgen *girgen.NamespaceGenerator) error

func GioArrayUseBytes 

func GioArrayUseBytes(nsgen *girgen.NamespaceGenerator) error

GioArrayUseBytes is the postprocessor that adds gio/v2.UseBytes.

func GtkInvalidListItem 

func GtkInvalidListItem(nsgen *girgen.NamespaceGenerator) error

func GtkLockOSThread 

func GtkLockOSThread(nsgen *girgen.NamespaceGenerator) error

func GtkNewDialog 

func GtkNewDialog(nsgen *girgen.NamespaceGenerator) error

func GtkNewMessageDialog 

func GtkNewMessageDialog(nsgen *girgen.NamespaceGenerator) error

func ImportGError 

func ImportGError(nsgen *girgen.NamespaceGenerator) error
