Constructor Detail

LwjglWindow

public LwjglWindow(JmeContext.Type type)

Method Detail

getType

public JmeContext.Type getType()

Specified by:

getType in interface JmeContext

Returns:

Type.Display or Type.Canvas

setTitle

public void setTitle(java.lang.String title)

Set the title if it's a windowed display

Specified by:

setTitle in interface JmeContext

Parameters:

title - the title to set

restart

public void restart()

Restart if it's a windowed or full-screen display.

Specified by:

restart in interface JmeContext

createContext

protected void createContext(AppSettings settings)

Apply the settings, changing resolution, etc.

Parameters:

settings - the settings to apply when creating the context.

showWindow

protected void showWindow()

setWindowIcon

protected void setWindowIcon(AppSettings settings)

Set custom icons to the window of this application.

Parameters:

settings - settings for getting the icons

destroyContext

protected void destroyContext()

Destroy the context.

create

public void create(boolean waitFor)

Description copied from interface: JmeContext

Creates the context and makes it active.

Specified by:

create in interface JmeContext

Parameters:

waitFor - If true, will wait until context has initialized.

initInThread

protected boolean initInThread()

Does LWJGL display initialization in the OpenGL thread

Returns:

returns true if the context initialization was successful

runLoop

protected void runLoop()

execute one iteration of the render loop in the OpenGL thread

deinitInThread

protected void deinitInThread()

De-initialize in the OpenGL thread.

run

public void run()

Specified by:

run in interface java.lang.Runnable

getJoyInput

public JoyInput getJoyInput()

Specified by:

getJoyInput in interface JmeContext

Returns:

Joystick input implementation. May be null if not available.

getMouseInput

public MouseInput getMouseInput()

Specified by:

getMouseInput in interface JmeContext

Returns:

Mouse input implementation. May be null if not available.

getKeyInput

public KeyInput getKeyInput()

Specified by:

getKeyInput in interface JmeContext

Returns:

Keyboard input implementation. May be null if not available.

getTouchInput

public TouchInput getTouchInput()

Specified by:

getTouchInput in interface JmeContext

Returns:

Touch device input implementation. May be null if not available.

setAutoFlushFrames

public void setAutoFlushFrames(boolean enabled)

Specified by:

setAutoFlushFrames in interface JmeContext

Parameters:

enabled - If enabled, the context will automatically flush frames to the video card (swap buffers) after an update cycle.

destroy

public void destroy(boolean waitFor)

Description copied from interface: JmeContext

Destroys the context completely, making it inactive.

Specified by:

destroy in interface JmeContext

Parameters:

waitFor - If true, will wait until the context is destroyed fully.

getWindowHandle

public long getWindowHandle()

getWindowContentScale

public Vector2f getWindowContentScale(Vector2f store)

Get the window content scale, for HiDPI support. The content scale is the ratio between the current DPI and the platform's default DPI. This is especially important for text and any UI elements. If the pixel dimensions of your UI scaled by this look appropriate on your machine then it should appear at a reasonable size on other machines regardless of their DPI and scaling settings. This relies on the system DPI and scaling settings being somewhat correct.

Parameters:

store - A vector2f to store the result

Returns:

The window content scale
