<H2>DESCRIPTION</H2>
|
|
|
|
<P>
|
|
|
|
<I>Xev</I> creates a window and then asks the X server to send it
|
|
<I>events</I> whenever anything happens to the window (such as it being
|
|
moved, resized, typed in, clicked in, etc.). You can also attach it to an
|
|
existing window. It is useful for seeing what causes events to occur and to
|
|
display the information that they contain; it is essentially a debugging and
|
|
development tool, and should not be needed in normal usage.

|
|
<H2>OPTIONS</H2>
|
|
|
|
<DL COMPACT>
|
|
<DT id="1"><B>-display </B><I>display</I>
|
|
|
|
<DD>
|
|
This option specifies the X server to contact.
|
|
<DT id="2"><B>-geometry </B><I>geom</I>
|
|
|
|
<DD>
|
|
This option specifies the size and/or location of the window, if a window is
|
|
to be created.
|
|
<DT id="3"><B>-bw </B><I>pixels</I>
|
|
|
|
<DD>
|
|
This option specifies the border width for the window.
|
|
<DT id="4"><B>-bs </B><I>{NotUseful,WhenMapped,Always}</I>
|
|
|
|
<DD>
|
|
This option specifies what kind of backing store to give the window.
|
|
The default is NotUseful. Backing store refers to the the pixels saved
|
|
off-screen when the X server maintains the contents of a window; NotUseful
|
|
means that the xev process will redraw its contents itself, as necessary.
|
|
<DT id="5"><B>-id </B><I>windowid</I>
|
|
|
|
<DD>
|
|
This option specifies that the window with the given id should be
|
|
monitored, instead of creating a new window.
|
|
<DT id="6"><B>-root</B>
|
|
|
|
<DD>
|
|
This option specifies that the root window should be
|
|
monitored, instead of creating a new window.
|
|
<DT id="7"><B>-s</B>
|
|
|
|
<DD>
|
|
This option specifies that save-unders should be enabled on the window. Save
|
|
unders are similar to backing store, but they refer rather to the saving of
|
|
pixels off-screen when the current window obscures other windows. Save
|
|
unders are only advisory, and are normally set for popup dialogs and other
|
|
transient windows.
|
|
<DT id="8"><B>-name </B><I>string</I>
|
|
|
|
<DD>
|
|
This option specifies the name to assign to the created window.
|
|
<DT id="9"><B>-rv</B>
|
|
|
|
<DD>
|
|
This option specifies that the window should be in reverse video.
|
|
<DT id="10"><B>-event </B><I>event_mask</I>
|
|
|
|
<DD>
|
|
Select which events to display.
|
|
The
|
|
<B>-event</B>
|
|
|
|
option can be specified multiple times to select multiple types of events.
|
|
When not specified, all events are selected.
|
|
Available event masks: keyboard mouse expose visibility structure substructure
|
|
focus property colormap owner_grab_button randr button
|
|
<DT id="11"><B>-version</B>
|
|
|
|
<DD>
|
|
This option prints the program version and exits.
