Parameter |
Description |
|
sysgui |
SYSGUI channel. |
|
id |
Grid control ID. |
|
67 |
Number of this SENDMSG() function. |
|
rows |
Number of rows. Valid values are 0 to 2,100,000,000. (Column numbers are zero-based.) |
|
$$ |
Always null. |
This function is valid only for main grids (heading grids are automatically
updated if they exist). This function does not change the size of the
grid control, so reducing the number of rows may cause the bottom part
of the grid's space to go blank.
The return value is a binary representation of the number of rows set by
this function. Use DEC(ROWS$) to get the numeric representation.
Example
The following example creates a grid with three rows and reduces the number of rows to two:
sysgui=unt; open (sysgui)"X0"
print (sysgui)'window'(0,20,650,120,"Grid Sample",$00000082$,$FF$)
print (sysgui)'grid'(100,20,20,580,74,$0866$,3,3,5,18,101,30,102)
rows$=sendmsg(sysgui,100,67,2,$$)
print dec($00$+rows$)
