NAMEDtWsmGetWorkspaceInfo — get detailed workspace information
SYNOPSIS
#include <Dt/Wsm.h>
int DtWsmGetWorkspaceInfo(
Display *display,
Window root,
Atom aWorkspace,
DtWsmWorkspaceInfo **ppWsInfo);
DESCRIPTION
The DtWsmGetWorkspaceInfo function works with the CDE workspace man‐
ager, dtwm(1), and returns detailed information on a specific
workspace.
The display argument is the X display.
The root argument is the root window of the screen of interest.
The aWorkspace argument is the workspace name (converted to an X atom).
The *ppWsInfo argument is the address of a variable to receive the
returned pointer to the workspace information data.
The DtWsmWorkspaceInfo structure contains at least the following mem‐
bers:
Atom workspace The workspace name (con‐
verted to an X atom).
unsigned long bg The pixel ID used for the
background color of the
backdrop.
unsigned long fg The pixel ID used for the
foreground color of the
backdrop.
Atom backdropName The backdrop file name
(converted to an X atom).
The file must be in either
X Bitmap file format (with
extension .bm) or X Pixmap
file format (with extension
.pm). The workspace man‐
agement services look for
the file along the same
path used for searching
icons. The directory
/usr/dt/backdrops is the
default directory if the
file cannot be found along
the icon search path.
int colorSetId The colorset number used
for this workspace, which
affects the backdrop color
and the button color for
this workspace on the front
panel.
char *pchTitle The title displayed in the
button for this workspace
on the front panel. This
string is interpreted in
the locale in which the CDE
workspace manager, dtwm(1),
is running. The title is
different from the
workspace name. The
workspace name, when con‐
verted from an X atom, is
used as the identifier for
a workspace in the
workspace manager function
calls. The CDE workspace
manager, dtwm(1). also uses
the workspace name as a
resource name; thus, the
characters used in a
workspace name are
restricted to the charac‐
ters in the X Portable
Character Set. The
workspace name for a
workspace created from the
front panel is generated
automatically by the CDE
workspace manager, dtwm(1).
Window *backdropWindows A pointer to an array of
windows that make up the
backdrop.
int numBackdropWindows The number of elements in
the backdropWindows array.
RETURN VALUE
Upon successful completion, the DtWsmGetWorkspaceInfo function returns
Success and the workspace manager returns in *ppWsInfo a pointer to a
DtWsmInfo structure that contains information about the workspace
aWorkspace; otherwise, it returns a value not equal to Success.
APPLICATION USAGE
If the DtWsmGetWorkspaceInfo function is not successful, failure may be
due to a memory allocation error or failure to find the correct
workspace information (that is, the CDE workspace manager, dtwm(1), is
not running). The application must use the DtWsmFreeWorkspaceInfo(3)
function to free the data returned in *ppWsInfo. The *backdropWindows
pointer may be useful for applications that are interested in some
events on the root window. Since the backdrop covers the root window,
the backdrop catches the button events before they reach the root.
