Error

public class Error
extends java.lang.Error

X server core error. This class is based on Error instead of Exception or RuntimeException because X server error should be regarded as fatal. Instead of setting error handler with XSetErrorHandler in C programming, we should utilize the exception facility of Java programming.

Field Detail

SUCCESS

public static final int SUCCESS

Constant Field Values

BAD_REQUEST

public static final int BAD_REQUEST

The major or minor opcode does not specify a valid request. This usually is an Xlib or server error.

See Also:

Constant Field Values

BAD_VALUE

public static final int BAD_VALUE

Some numeric value falls outside of the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives typically can generate this error (due to the encoding).

See Also:

Constant Field Values

BAD_WINDOW

public static final int BAD_WINDOW

A value for a window argument does not name a defined window.

See Also:

Constant Field Values

BAD_PIXMAP

public static final int BAD_PIXMAP

A value for a pixmap argument does not name a defined pixmap.

See Also:

Constant Field Values

BAD_ATOM

public static final int BAD_ATOM

A value for an Atom argument does not name a defined Atom.

See Also:

Constant Field Values

BAD_CURSOR

public static final int BAD_CURSOR

A value for a cursor argument does not name a defined cursor.

See Also:

Constant Field Values

BAD_FONT

public static final int BAD_FONT

A value for a font argument does not name a defined font (or, in some cases, GContext).

See Also:

Constant Field Values

BAD_MATCH

public static final int BAD_MATCH

In a graphics request, the root and depth of the graphics context do not match those of the drawable. An InputOnly window is used as a drawable. Some argument or pair of arguments has the correct type and range, but it fails to match in some other way required by the request. An InputOnly window lacks this attribute.

See Also:

Constant Field Values

BAD_DRAWABLE

public static final int BAD_DRAWABLE

A value for a drawable argument does not name a defined window or pixmap.

See Also:

Constant Field Values

BAD_ACCESS

public static final int BAD_ACCESS

A client attempts to grab a key/button combination already grabbed by another client.

A client attempts to free a colormap entry that it had not already allocated or to free an entry in a colormap that was created with all entries writable.

A client attempts to store into a read-only or unallocated colormap entry.

A client attempts to modify the access control list from other than the local (or otherwise authorized) host.

A client attempts to select an event type that another client has already selected.

See Also:

Constant Field Values

BAD_ALLOC

public static final int BAD_ALLOC

The server fails to allocate the requested resource. Note that the explicit listing of BadAlloc errors in requests only covers allocation errors at a very coarse level and is not intended to (nor can it in practice hope to) cover all cases of a server running out of allocation space in the middle of service. The semantics when a server runs out of allocation space are left unspecified, but a server may generate a BadAlloc error on any request for this reason, and clients should be prepared to receive such errors and handle or discard them.

See Also:

Constant Field Values

BAD_COLORMAP

public static final int BAD_COLORMAP

A value for a Colormap argument does not name a defined Colormap.

See Also:

Constant Field Values

BAD_GC

public static final int BAD_GC

A value for a GContext argument does not name a defined GContext.

See Also:

Constant Field Values

BAD_ID_CHOICE

public static final int BAD_ID_CHOICE

The value chosen for a resource identifier either is not included in the range assigned to the client or is already in use. Under normal circumstances, this cannot occur and should be considered a server or Xlib error.

See Also:

Constant Field Values

BAD_NAME

public static final int BAD_NAME

A font or color of the specified name does not exist.

See Also:

Constant Field Values

BAD_LENGTH

public static final int BAD_LENGTH

The length of a request is shorter or longer than that required to contain the arguments. This is an internal Xlib or server error. The length of a request exceeds the maximum length accepted by the server.

See Also:

Constant Field Values

BAD_IMPLEMENTATION

public static final int BAD_IMPLEMENTATION

The server does not implement some aspect of the request. A server that generates this error for a core request is deficient. As such, this error is not listed for any of the requests, but clients should be prepared to receive such errors and handle or discard them.
