QR SET INFO COLUMN


QR SET INFO COLUMN ( area ; colNum ; title ; object ; hide ; size ; repeatedValue ; displayFormat )

Parameter	Type	Description
area	Longint	Reference of the area
colNum	Longint	Column number
title	String	Title of the column
object	Field, Variable	Object assigned for that column
hide	Longint	0 = displayed, 1 = hidden
size	Longint	Column size
repeatedValue	Longint	0 = not repeated, 1 = repeated
displayFormat	String	Format for the data

Description

List mode

The QR SET INFO COLUMN command sets the parameters of an existing column.

area is the reference of the Quick Report area.

colNum is the number of the column to modify.

title is the title that will be displayed in the header of the column.

object is the actual object of the column (variable, field or formula).

hide specifies whether the column is shown or hidden:

If hide is 1, the column is hidden;
If hide is 0, the column is shown.

size is the size in pixels to assign to the column. If size is -1, the size is made automatic.

repeatedValue is the status for data repetition. For example, if the value for a field or variable does not change from one record to the other, it may or may not be repeated when they do not change.

If repeatedValue equals 0, values are not repeated.
If repeatedValue equals 1, values are repeated.

displayFormat is the display format. Display formats are the 4D formats compatible with the data displayed.

The following statement sets the title of column #1 to Title, sets the contents of the body to Field2, makes the column visible with a width of 150 pixels and sets the format to ###,##.

QR SET INFO COLUMN(area;1;"Title";"[Table 1]Field2";0;150;0;"###,##")

The QR SET INFO COLUMN command allows you to set the same parameters but the reference of the areas to which it applies is different and varies depending on the parameter you want to set.
First of all, the title, hide, and repeatedValue parameters are not used when this command is used in cross-table mode. The value to use for colNum varies depending on whether you want to set the column size or the data source and display format.

Column size
This is a “visual” attribute, therefore columns are numbered from left to right, as depicted below.

The following statement will set the size to automatic for all the columns in a cross-table report and will leave other elements unchanged:

 For($i;1;3)

    QR GET INFO COLUMN(qr_area;$i;$title;$obj;$hide;$size;$rep;$format)

    QR SET INFO COLUMN(qr_area;$i;$title;$obj;$hide;0;$rep;$format)

 End for

You will notice that since you want to alter only the column size, you have to use QR GET INFO COLUMN to retrieve the column properties and pass them to QR SET INFO COLUMN to leave it unchanged, except for the column size.

Data source (object) and display format
In this case the numbering of columns operates as depicted below:

You will notice that not all cells can be addressed using the QR SET INFO COLUMN command, the cells that are not numbered above are addressed using QR SET TOTALS DATA.

The following code assigns data sources to the three cells required for creating a basic cross-table report:

 QR SET REPORT TABLE(qr_area;Table(->[Invoices]))

 ALL RECORDS([Invoices])

 QR SET REPORT KIND(qr_area;2)

 QR SET INFO COLUMN(qr_area;1;"";->[Invoices]Item;1;-1;1;"")

 QR SET INFO COLUMN(qr_area;2;"";->[Invoices]Quarter;1;-1;1;"")

 QR SET INFO COLUMN(qr_area;3;"";->[Invoices]Quantity;1;-1;1;"")

This would be the resulting report area:

If you pass an invalid area number, the error -9850 will be generated.
If you pass an invalid colNum value, the error -9852 will be generated.
