Method Detail

getDrawingSurface

public static JAWT_DrawingSurface getDrawingSurface(java.awt.Component component)

Obtains drawing surface for a given component. The surface should be freed by calling freeDrawingSurface().

Parameters:

component - the target component (should be a window or a canvas for native rendering).

Returns:

the drawing surface structure for the specified component.

freeDrawingSurface

public static void freeDrawingSurface(JAWT_DrawingSurface ds)

Releases the drawing surface.

Parameters:

ds - a drawing surface structure.

lockAWT

public static void lockAWT()

Locks the AWT for synchronization purposes.

unlockAWT

public static void unlockAWT()

Unlocks the AWT.

getComponentFromHandle

public static java.awt.Component getComponentFromHandle(Pointer.Void handle)

Gets an AWT component by a given native handle.

Parameters:

handle - a handle.

Returns:

a component that corresponds to the given handle or null if no such component exists.
