infoItem can be one of the following:
BACKCOLOR- WINFO returns 1 if the device supports
background colors.
BATCH- WINFO returns 1 if the application
is running in batch mode.
COMMAND- WINFO returns 1 if the window has
a command line.
CURSCREEN- WINFO returns the number of the SCREEN
or FRAME entry in which the cursor is located.
CURSORCOL- WINFO returns the column number of
the cursor position.
CURSORROW- WINFO returns the row number of the
cursor position.
GRAPHICS- WINFO returns 1 if the user's output
device supports graphics.
ICON- WINFO returns the number of Institute-supplied
icons available under the user's host operating system. See the SAS documentation
for your operating system for information about whether SAS software supports
icons under your host operating system.
LOGON- WINFO returns 1 if a logon was specified
when the SAS/AF application was invoked.
MAXCOL- WINFO returns the maximum number
of columns to which the window can grow, excluding the command and border
areas.
MAXROW- WINFO returns the maximum number
of rows to which the window can grow, excluding the command and border areas.
MONO- WINFO returns 1 if the device is
monochrome.
NSCREEN- WINFO returns information about the
windows currently open in an application:
FSEDIT applications return the number of screens that
are defined for the current FSEDIT window.
FSVIEW applications return 4 to indicate the four parts
of the FSVIEW window: the column title area, the row number or ID column area,
the data area, and the area above the column titles.
SAS/AF applications return 1 or 2 if you used ^^^ or
¬ ¬ ¬ to divide the entry's window into two or more frames.
NUMCOLS- WINFO returns the current number
of columns in the window.
NUMROWS- WINFO returns the current number
of rows in the window.
NUMXINCH- WINFO returns the number of pixels
per horizontal inch of the window (valid only for FRAME entries).
NUMYINCH- WINFO returns the number of pixels
per vertical inch of the window (valid only for FRAME entries).
NUMXPIXEL- WINFO returns the window width in
pixels (valid only for FRAME entries).
NUMYPIXEL- WINFO returns the window height in
pixels (valid only for FRAME entries).
PANECCOL- WINFO returns the column position
of the cursor relative to the pane of the window in which it resides. Use aux-info to specify the
pane.
PANECROW- WINFO returns the row position of
the cursor relative to the pane of the window in which it resides. Use aux-info to specify the
pane.
PANECOL- WINFO returns the number of columns
in a specified pane. Use aux-info to specify
the pane.
PANEROW- WINFO returns the number of rows
in a specified pane. Use aux-info to specify
the pane.
PMENU- WINFO returns 1 if a PMENU entry
has been specified for this program regardless of whether the PMENU facility
is currently active for the window.
PMENUGRAY- WINFO returns 0 when it grays or
ungrays selections in the window's pull-down menus. Use aux-info to specify which selection to gray or
ungray.
PMENUSTATE- WINFO returns 0 when it enables or
disables the state of a selection in the window's pull-down menus. Use aux-info to specify the state.
POPUP- WINFO returns 0 when it enables or
disables pop-up events in the window. Use the aux-info
argument to specify whether events are to be enabled or disabled.
STARTCOL- WINFO returns the current column
on which the window starts.
STARTROW- WINFO returns the current row on
which the window starts.
UICON- WINFO returns the number of user-defined
icons available under the user's host operating system.
XPIXCELL- WINFO returns the width (in pixels)
of the font used in the SAS windowing environment.
XPIXEL- WINFO returns the horizontal location
(in pixels) of the most recent mouse event.
YPIXCELL- WINFO returns the height (in pixels)
of the font used in the SAS windowing environment.
YPIXEL- WINFO returns the vertical location
(in pixels) of the most recent mouse event.
Because _init runs before a display is created, you cannot use 'PMENUGRAY'
and 'PMENUSTATE'.
If a frame's method is overridden and points to an SCL entry, using
the WINFO function within the overridden method returns information about
the SCL entry rather than the frame. To get information about the frame, use
_winfo.
If _winfo is invoked from the _init method of the frame, not all infoItems can be queried. The _init method of the frame runs before
the display is created, so many of the infoItems that return
information about the display cannot return valid values.
