class GridFieldPrintButton implements GridField_HTMLProvider, GridField_ActionProvider, GridField_URLHandler
Adds an "Print" button to the bottom or top of a GridField.
Traits
Methods
Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located
Return the names of all the methods available on this object
Add an extension to a specific class.
No description
Get extra config sources for this class
Return TRUE if a class has a specified extension.
Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array
Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed
Get an extension instance attached to this object by name.
Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link has_extension()} to check if a class (not an instance) has a specific extension.
Get all extension instances for this specific object instance.

Handle the print, for both the action button and the URL

__call(string $method, array $arguments)
Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located
You can add extra methods to a class using {@link Extensions}, {@link Object::createMethod()} or {@link Object::addWrapperMethod()}

bool
hasMethod(string $method)
Return TRUE if a method exists on this object
This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions

array
allMethodNames(bool $custom = false)
Return the names of all the methods available on this object

static bool
add_extension(string $classOrExtension, string $extension = null)
Add an extension to a specific class.
The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.
As an alternative, extensions can be added to a specific class directly in the {@link Object::$extensions} array. See {@link SiteTree::$extensions} for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through {@link singleton()}).

static
remove_extension(string $extension)
Remove an extension from a class.
Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.
Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any {@link Object} instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through {@link singleton()} to avoid side-effects from stale extension information.

static bool
has_extension(string $classOrExtension, string $requiredExtension = null, boolean $strict = false)
Return TRUE if a class has a specified extension.
This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

invokeWithExtensions(string $method, mixed $arguments)
Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array

array
extend(string $method, mixed $arguments)
Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed
Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.
The extension methods are defined during {@link __construct()} in {@link defineMethods()}.

getExtensionInstance(string $extension)
Get an extension instance attached to this object by name.

bool
hasExtension(string $extension)
Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link has_extension()} to check if a class (not an instance) has a specific extension.
Caution: Don't use singleton(

Extension[]
getExtensionInstances()
Get all extension instances for this specific object instance.
See {@link get_extensions()} to get all applied extension classes for this class (not the instance).
This method also provides lazy-population of the extension_instances property.
