Member Function Documentation

◆ attachGui()

void tgui::BackendGLFW::attachGui ( BackendGui * gui )

overridevirtual

Informs the backend that a new gui object has been created.

Parameters

gui	Newly created gui

Implements tgui::Backend.

◆ detatchGui()

void tgui::BackendGLFW::detatchGui ( BackendGui * gui )

overridevirtual

Informs the backend that a gui object is being destroyed.

Parameters

gui	Gui object that is about to be deconstructed

Implements tgui::Backend.

◆ getClipboard()

String tgui::BackendGLFW::getClipboard ( ) const

overridevirtual

Returns the contents of the clipboard.

Returns: Clipboard contents

Reimplemented from tgui::Backend.

◆ isKeyboardModifierPressed()

bool tgui::BackendGLFW::isKeyboardModifierPressed ( Event::KeyModifier modifierKey )

overridevirtual

Checks the state for one of the modifier keys.

Parameters

modifierKey The modifier key of which the state is being queried

Returns: Whether queries modifier key is being pressed

Implements tgui::Backend.

◆ resetMouseCursorStyle()

void tgui::BackendGLFW::resetMouseCursorStyle ( Cursor::Type type )

overridevirtual

Parameters

gui	The gui that represents the window for which the mouse cursor should be changed
type	Which cursor to use

Implements tgui::Backend.

◆ setMouseCursorStyle()

void tgui::BackendGLFW::setMouseCursorStyle	(	Cursor::Type	type,
		const std::uint8_t *	pixels,
		Vector2u	size,
