Interface Lwjgl3WindowListener

All Known Implementing Classes:

Lwjgl3WindowAdapter

public interface Lwjgl3WindowListener

Receives notifications of various window events, such as iconification, focus loss and gain, and window close events. Can be set per window via Lwjgl3ApplicationConfiguration and Lwjgl3WindowConfiguration. Close events can be canceled by returning false.

Method Summary

Modifier and Type	Method and Description
boolean	closeRequested() Called when the user requested to close the window, e.g.
void	created(Lwjgl3Window window) Called after the GLFW window is created.
void	filesDropped(java.lang.String[] files) Called when external files are dropped into the window, e.g from the Desktop.
void	focusGained() Called when the window gained focus.
void	focusLost() Called when the window lost focus to another window.
void	iconified(boolean isIconified) Called when the window is iconified (i.e.
void	maximized(boolean isMaximized) Called when the window is maximized, or restored from the maximized state.
void	refreshRequested() Called when the window content is damaged and needs to be refreshed.

Method Detail

created

void created(Lwjgl3Window window)

Called after the GLFW window is created. Before this callback is received, it's unsafe to use any Lwjgl3Window member functions which, for their part, involve calling GLFW functions. For the main window, this is an immediate callback from inside Lwjgl3Application(ApplicationListener, Lwjgl3ApplicationConfiguration).

Parameters:

window - the window instance

See Also:

Lwjgl3Application.newWindow(ApplicationListener, Lwjgl3WindowConfiguration)

iconified

void iconified(boolean isIconified)

Called when the window is iconified (i.e. its minimize button was clicked), or when restored from the iconified state. When a window becomes iconified, its ApplicationListener will be paused, and when restored it will be resumed.

Parameters:

isIconified - True if window is iconified, false if it leaves the iconified state

maximized

void maximized(boolean isMaximized)

Called when the window is maximized, or restored from the maximized state.

Parameters:

isMaximized - true if window is maximized, false if it leaves the maximized state

focusLost

void focusLost()

Called when the window lost focus to another window. The window's ApplicationListener will continue to be called.

focusGained

void focusGained()

Called when the window gained focus.

closeRequested

boolean closeRequested()

Called when the user requested to close the window, e.g. clicking the close button or pressing the window closing keyboard shortcut.

Returns:

whether the window should actually close

filesDropped

void filesDropped(java.lang.String[] files)

Called when external files are dropped into the window, e.g from the Desktop.

Parameters:

files - array with absolute paths to the files

refreshRequested

void refreshRequested()

Called when the window content is damaged and needs to be refreshed. When this occurs, Lwjgl3Graphics.requestRendering() is automatically called.
