 java.awt.ComponentXWindow
All known Subclasses: java.awt.HeavyweightComponentXWindow,
| ComponentXWindow | | class ComponentXWindow (Code) | | The X window used by a component to get mouse events from the X server. This winow represents an InputOnly
window in X (an invisible window that can be used to select and receive events).

| Field Summary | |
| Component | component
The component this X window is for. | | int | windowID
The native X Window id. | | boolean | zeroSize
true if size is set to zero in either width or height. |
| Method Summary | |
| void | create()
Creates the component's X window. | | native void | dispose()
Destroys the X window. | | native Point | getLocationOnScreen()
Gets the location of the X window on the screen. | | void | map()
Maps the X window. | | native void | mapNative()
Maps the X window using XMapWindow xlib function. | | void | postMouseButtonEvent(int id, long when, int modifiers, int x, int y)
Called when a mouse button event is received from the X server for this X window.
Posts required AWTEvents into the Java event queue for processing. | | void | postMouseEvent(int id, long when, int modifiers, int x, int y)
Called when a mouse motion event is received from the X server for this X window.
Posts required AWTEvents into the Java event queue for processing. | | void | setBackground(Color c)
Sets the background for this x window. | | void | setBounds(int x, int y, int width, int height)
| | native void | setBoundsNative(int x, int y, int width, int height)
Sets the bounds for this X window using XMoveResizeWindow xlib function. | | void | setCursor(Cursor cursor)
| | native void | setCursorNative(int type)
| | native void | setMouseEventMask(long mask)
Sets the event mask for the X window using the supplied event mask (see AWTEvent).
This lets the X server know what kinds of events we are interested in. | | native void | unmap()
Unmaps the X window using the XUnmapWindow xlib function. |
| windowID | | int windowID(Code) | | The native X Window id.
|
| zeroSize | | boolean zeroSize(Code) | | true if size is set to zero in either width or height. This is necessary
as X doesn't allow 0 size windows.
|
| create | | void create()(Code) | | Creates the component's X window.
|
| dispose | | native void dispose()(Code) | | Destroys the X window.
|
| getLocationOnScreen | | native Point getLocationOnScreen()(Code) | | Gets the location of the X window on the screen.
|
| map | | void map()(Code) | | Maps the X window. This will only map the window if the size is non zero for
both the width and height.
|
| mapNative | | native void mapNative()(Code) | | Maps the X window using XMapWindow xlib function.
|
| postMouseButtonEvent | | void postMouseButtonEvent(int id, long when, int modifiers, int x, int y)(Code) | | Called when a mouse button event is received from the X server for this X window.
Posts required AWTEvents into the Java event queue for processing. This method will
determine the click count.
|
| postMouseEvent | | void postMouseEvent(int id, long when, int modifiers, int x, int y)(Code) | | Called when a mouse motion event is received from the X server for this X window.
Posts required AWTEvents into the Java event queue for processing.
|
| setBackground | | void setBackground(Color c)(Code) | | Sets the background for this x window. As this is an InputOnly X window we don't do anything
but sub classes need to override this if the X window is an InputOutput X window.
|
| setBounds | | void setBounds(int x, int y, int width, int height)(Code) | | |
| setBoundsNative | | native void setBoundsNative(int x, int y, int width, int height)(Code) | | Sets the bounds for this X window using XMoveResizeWindow xlib function. Note that
this function should not be called with a width or height of zero as X will generate errors.
|
| setCursorNative | | native void setCursorNative(int type)(Code) | | |
| setMouseEventMask | | native void setMouseEventMask(long mask)(Code) | | Sets the event mask for the X window using the supplied event mask (see AWTEvent).
This lets the X server know what kinds of events we are interested in.
|
| unmap | | native void unmap()(Code) | | Unmaps the X window using the XUnmapWindow xlib function.
