Converts a color from HSV space to RGB.

Call this function before using any other GTK functions in your GUI applications. It will initialize everything needed to operate the toolkit and parses some standard command line options.

This function does the same work as gtk_init() with only a single change: It does not terminate the program if the windowing system can’t be initialized. Instead it returns FALSE on failure.

Use this function to check if GTK has been initialized with gtk_init() or gtk_init_check().

Creates a new GParamSpec instance for a property holding a GtkExpression.

Runs a page setup dialog, letting the user modify the values from page_setup. If the user cancels the dialog, the returned GtkPageSetup is identical to the passed in page_setup, otherwise it contains the modifications done in the dialog.

Runs a page setup dialog, letting the user modify the values from page_setup.

Renders an activity indicator (such as in GtkSpinner). The state GTK_STATE_FLAG_CHECKED determines whether there is activity going on.

Renders an arrow pointing to angle.

Renders the background of an element.

Renders a checkmark (as in a GtkCheckButton).

Renders an expander (as used in GtkTreeView and GtkExpander) in the area defined by x, y, width, height. The state GTK_STATE_FLAG_CHECKED determines whether the expander is collapsed or expanded.

Renders a focus indicator on the rectangle determined by x, y, width, height.

Renders a frame around the rectangle defined by x, y, width, height.

Renders a handle (as in GtkPaned and GtkWindow’s resize grip), in the rectangle determined by x, y, width, height.

Renders the icon in texture at the specified x and y coordinates.

Renders layout on the coordinates x, y

Renders a line from (x0, y0) to (x1, y1).

Renders an option mark (as in a radio button), the GTK_STATE_FLAG_CHECKED state will determine whether the option is on or off, and GTK_STATE_FLAG_INCONSISTENT whether it should be marked as undefined.

Converts a color from RGB space to HSV.

Sets the GTK debug flags.

A convenience function for showing an application’s about dialog.

This function launches the default application for showing a given uri, or shows an error dialog if that fails.

This function launches the default application for showing a given uri.

Finishes the gtk_show_uri() call and returns the result of the operation.

Checks whether the accessible property of accessible is set to a specific value.

Checks whether the accessible relation of accessible is set to a specific value.

Checks whether the accessible state of accessible is set to a specific value.

Checks whether the GtkAccessible has property set.

Checks whether the GtkAccessible has relation set.

Checks whether the GtkAccessible:accessible-role of the accessible is role.

Checks whether the GtkAccessible has state set.

This function is used to initialize a GTK test program.

Return the type ids that have been registered after calling gtk_test_register_all_types().

Force registration of all core GTK object types.

Enters the main loop and waits for widget to be “drawn”.

Creates a content provider for dragging path from tree_model.

Obtains a tree_model and path from value of target type GTK_TYPE_TREE_ROW_DATA.

Retrieves the GtkExpression stored inside the given value, and acquires a reference to it.

Retrieves the GtkExpression stored inside the given value.

Stores the given GtkExpression inside value.

Stores the given GtkExpression inside value.

This macro should be used to emit a warning about and unexpected type value in a GtkBuildable add_child implementation.

This macro should be used to emit a standard warning about unexpected properties in set_cell_property() and get_cell_property() implementations.

Returns TRUE if the version of the GTK header files is the same as or newer than the passed-in version.

Checks whether a GtkAccessible implementation has the given role, and raises an assertion if the condition is failed.

Evaluates to TRUE if value was initialized with GTK_TYPE_EXPRESSION.

Binds a callback function defined in a template to the widget_class.

Binds a child widget defined in a template to the widget_class.

Binds a child widget defined in a template to the widget_class, and also makes it available as an internal child in GtkBuilder, under the name member_name.

Binds a child widget defined in a template to the widget_class, and also makes it available as an internal child in GtkBuilder, under the name member_name.

Binds a child widget defined in a template to the widget_class.

An undefined value. The accessible attribute is either unset, or its value is undefined.

Like gtk_get_binary_age(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Constant to return from a signal handler for the ::input signal in case of conversion failure.

Like gtk_get_interface_age(), but from the headers used at application compile time, rather than from the library linked against at application run time.

The value used to refer to a guaranteed invalid position in a GListModel. This value may be returned from some functions, others may accept it as input. Its interpretation may differ for different functions.

The name used for the stock full offset included by GtkLevelBar.

The name used for the stock high offset included by GtkLevelBar.

The name used for the stock low offset included by GtkLevelBar.

Like gtk_get_major_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Like gtk_get_micro_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.

Like gtk_get_minor_version(), but from the headers used at application compile time, rather than from the library linked against at application run time.
