QGObs_SetPicture

QGObs_SetPicture(areaRef; tableNum; fieldNum; rectLeft; rectTop; rectRight; rectBottom; displayFormat):errorCode
areaRef Longint QGrid area reference
tableNum Longint Table number
fieldNum Longint Field number
rectLeft Longint Left coordinate
rectTop Longint Top coordinate
rectRight Longint Right coordinate
rectBottom Longint Bottom coordinate
displayFormat Longint Picture format number
error Longint Error result
Do not use this command in QGrid v1.1 or later

This QGrid v1.0 command is preserved in QGrid v1.1 for compatibility reasons.
It has been substituted by newer commands.


Sets up a picture object for area cells. Any previously defined picture object is deleted.

Parameter areaRef is the QGrid area reference. If areaRef is not a valid QGrid area reference, qg_paramErr error is returned.

Parameters tableNum and fieldNum specify the database field that will be the data source for the picture object. Passing a non-picture field will result in a qg_paramErr error.

Parameters rectLeft, rectTop, rectRight and rectBottom specify the picture box coordinates in the cell's coordinate system. Picture box coordinates can fall outside the cell bounds and even have negative values. In these cases only the visible part of the picture object's box is drawn on the cell. In case the values given do not specify a rectangle, error qg_InvalidRectErr is returned.

Long parameter displayFormat specifies the picture display format. QGrid defines the following constants for picture display formats:

qg_PictTruncCentered 1 Same as 4D's Truncated Centered (default)
qg_PictScaledToFit 2 Same as 4D's Scaled To Fit
qg_PictTruncNonCenter 4 Same as 4D's Truncated non Centered
qg_PictScaledToFitProp 5 Same as 4D's Scaled to fit proportional
qg_PictScaledToFitPropCenter 6 Same as 4D's Scaled to fit prop centered
qg_PictXScaledToFitProp 8 Same as 4D's Scaled to fit proportional, but scales up as well
qg_PictXScaledToFitPropCenter 9 Same as 4D's Scaled to fit prop centered, but scales up as well
Notes

Example

` Set-up a picture object for area xGrid
 
C_LONGINT($err;$tblNum;$fldNum;$left;$top;$right;$bottom;$format)
 
$tblNum:=Table(->[Images])
$fldNum:=Field(->[Images]Picture)
 
$left:=2
$top:=2
$right:=108
$bottom:=98
 
$format:=qg_PictXScaledToFitPropCenter
 
$err:=QGObs_SetPicture (xGrid;$tblNum;$fldNum;$left;$top;$right;$bottom;$format)
If ($err # qg_noErr)
  ` Handle the error
End if
