MSE |
Mouse State |
String, current state of mouse
The MSE variable contains a 32-byte string that describes the current state of the mouse. This table shows the positions of all mouse attributes represented in the MSE string:
MSE String |
Description | ||||||||||
(1,1) |
Current state:
| ||||||||||
(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 number | ||||||||||
(9,1) |
Absolute row number | ||||||||||
(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 scroll bar | ||||||||||
(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 Note: | ||||||||||
(29,2) |
Maximum Y (line) coordinates of the screen Note: | ||||||||||
(31,1) |
Returns current window state. Values correspond to the 'SHOW' mnemonic. DEC(MID(MSE,31,1)) Values: -1 Hidden | ||||||||||
(32,1) |
Returns either W for WindX or J for JavX ($00$ for no Thin-Client) |
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$="[WDX]"
To get the maximum screen size in lines and columns:
X$=mse
XCHAR=dec($00$+X$(10,1))
YCHAR=dec($00$+X$(11,1))
MAX_WIDE=int(dec(X$(27,2))/XCHAR)
MAX_HIGH=int(dec(X$(29,2))/YCHAR)
