Class ExposeEvent

public class ExposeEvent extends GtkEvent

Deprecated: This class is part of the java-gnome 2.x family of libraries, which, due to their inefficiency and complexity, are no longer being maintained and have been abandoned by the java-gnome project. Signal handling an connection has been completely re-implemented in java-gnome 4.0, so you will need to refactor any code attempting to use this class.

This event object is used to identify how expose has changed.

Method Detail

getArea

public Rectangle getArea()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the bounding box of region.

Returns: the bounding box of region.

getCount

public int getCount()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the number of contiguous EXPOSE events following this one. The only use for this is "exposure compression", i.e. handling all contiguous EXPOSE events in one go, though GDK performs some exposure compression so this is not normally needed.

Returns: the number of contiguous EXPOSE events following this one.

getRegion

public Region getRegion()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Returns the region that needs to be redrawn.

Returns: the region that needs to be redrawn.

getSendEvent

public boolean getSendEvent()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Check if the event was sent explicitly (eg using XSendEvent).

Returns: true if the event was sent explicitly (e.g. using XSendEvent), false otherwise.

getWindow

public Window getWindow()

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

The window which received the event.

Returns: the window which received the event.

isOfType

public boolean isOfType(ExposeEvent.Type test)

Deprecated: Superceeded by java-gnome 4.0; Signals all have individual interfaces each with a single method corresponding to the signature of the underlying callback.

Test to compare events.
