| Description |
This
system variable contains a 32-byte string that describes
the current state of the mouse. The following table shows
the positions of all mouse attributes represented in the MSE
string:
| MSE String |
Description |
| (1,1) |
Current
state:
| $FF$ |
Mouse inactive/unavailable
(e.g. Terminal, Unix/Linux console) |
| $00$ |
Mouse present - No buttons
pushed |
| $01$ |
Left button down. |
| $02$ |
Right button down. |
| $03$ |
Both buttons down. |
|
| (2,1) |
Current
mouse column in binary. |
| (3,1) |
Current
mouse line in binary. |
| (4,2) |
Current
mouse X (column) position in binary. |
| (6,2) |
Current
mouse Y (line) position in binary. |
| (8,1) |
Absolute
column #. |
| (9,1) |
Absolute
row #. |
| (10,1) |
Standard
character width. |
| (11,1) |
Standard
character height. |
| (12,1) |
Width
of Scroll box on standard scroll bar. |
| (13,1) |
Height
of Scroll box on standard scrollbar. |
| (14,2) |
Mouse
X (column) position relative to current window in
binary. |
| (16,2) |
Mouse
Y (line) position relative to current window in
binary. |
| (18,2) |
Current
control object with focus. |
| (20,2) |
Last
control object with focus, relative to the
current window. |
| (22,1) |
WindX/JavX
revision level from $00$ to $FF$ ($FF$ for no
thin-client). |
| (23,2) |
CTL
value for context-sensitive help. |
| (25,2) |
Last
control object to lose focus, relative to the
current window. |
| (27,2) |
Maximum
X (column) coordinates of the screen. (See Note) |
| (29,2) |
Maximum
Y (line) coordinates of the screen. (See Note) |
| (31,1) |
Returns
current window state. Values correspond to
'SHOW'( ) mnemonic.
| DEC(MID(MSE,31,1))
Values |
| -1 |
for hidden |
| 0 |
for minimized |
| 1 |
for normal |
| 2 |
for maximized |
|
| (32,1) |
Returns
either W for WindX or J for JavX ($00$ for no
thin client). |
|
| Examples |
The
following logic can be used to determine if WindX is
running by checking its version number
IF
MID(MSE,22,1)>$00$ AND MID(MSE,22,1)<$FF$ THEN
%WDX$="[WDX]"
To get the maximum screen
size in lines and columns:
0010 LET X$=MSE
0020
XCHAR=DEC($00$+X$(10,1))
0030
YCHAR=DEC($00$+X$(11,1))
0040
MAX_WIDE=INT(DEC(X$(27,2))/XCHAR)
0050
MAX_HIGH=INT(DEC(X$(29,2))/YCHAR)
