NAME
XIconifyWindow, XWithdrawWindow, XReconfigureWMWindow - manipulate top-
level windows
SYNTAX
Status XIconifyWindow(Display *display, Window w, int screen_number);
Status XWithdrawWindow(Display *display, Window w, int screen_number);
Status XReconfigureWMWindow(Display *display, Window w, int
screen_number, unsigned int value_mask, XWindowChanges *values);
ARGUMENTS
display Specifies the connection to the X server.
screen_number
Specifies the appropriate screen number on the host server.
value_mask
Specifies which values are to be set using information in the
values structure. This mask is the bitwise inclusive OR of
the valid configure window values bits.
values Specifies the XWindowChanges structure.
w Specifies the window.
DESCRIPTION
The XIconifyWindow function sends a WM_CHANGE_STATE ClientMessage event
with a format of 32 and a first data element of IconicState (as
described in section 4.1.4 of the Inter-Client Communication
Conventions Manual) and a window of w to the root window of the
specified screen with an event mask set to SubstructureNotifyMask|
SubstructureRedirectMask. Window managers may elect to receive this
message and if the window is in its normal state, may treat it as a
request to change the window’s state from normal to iconic. If the
WM_CHANGE_STATE property cannot be interned, XIconifyWindow does not
send a message and returns a zero status. It returns a nonzero status
if the client message is sent successfully; otherwise, it returns a
zero status.
The XWithdrawWindow function unmaps the specified window and sends a
synthetic UnmapNotify event to the root window of the specified screen.
Window managers may elect to receive this message and may treat it as a
request to change the window’s state to withdrawn. When a window is in
the withdrawn state, neither its normal nor its iconic representations
is visible. It returns a nonzero status if the UnmapNotify event is
successfully sent; otherwise, it returns a zero status.
XWithdrawWindow can generate a BadWindow error.
The XReconfigureWMWindow function issues a ConfigureWindow request on
the specified top-level window. If the stacking mode is changed and
the request fails with a BadMatch error, the error is trapped by Xlib
and a synthetic ConfigureRequestEvent containing the same configuration
parameters is sent to the root of the specified window. Window
managers may elect to receive this event and treat it as a request to
reconfigure the indicated window. It returns a nonzero status if the
request or event is successfully sent; otherwise, it returns a zero
status.
XReconfigureWMWindow can generate BadValue and BadWindow errors.
DIAGNOSTICS
BadValue Some numeric value falls outside 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 can
generate this error.
BadWindow A value for a Window argument does not name a defined Window.
