Returns information about the current window
|
rc=WINFO(info-item<,aux-info>);
|
- rc
- contains the return code for the operation.
Type:
Numeric
- info-item
- specifies either a characteristic of the
window or an action. See Values for Info-item.
Type:
Character
- aux-info
- specifies an additional argument that is
required by some info-item actions:
- pane-number (for
PANECOL,
PANECCOL, PANECROW, and PANEROW)
- is the number of the pane to be queried.
For example, in an extended table the non-scrollable section is pane 1 and
the scrollable portion is pane 2.
- item-id (for
PMENUGRAY)
- is the item identifier that you specified
with the ID= option for the ITEM statement in PROC PMENU when you built the
menu. Use the negative of the ID number to gray a selection, and use the positive
ID number to ungray a selection.
- item-id (for
PMENUSTATE)
- is the item identifier that you specified
with the ID= option for the ITEM statement in PROC PMENU when you built the
menu. Use the negative of the ID number to turn off the check mark or radio
button for the selection, and use the positive ID number to turn on the check
mark or radio button. Whether the menu selection gets a check mark or radio
button depends on the value of the STATE= option when the menu was built.
- flag (for
POPUP)
- can have the following values:
| 0 |
disables pop-up events. |
| 1 |
enables pop-up events. |
Type:
Numeric
