Method

Syntax

<oBrowser>:GetFirstVisibleColumn(

<iLastColumn>,

<iFirstColumn>,

<iOffset>

) Æ lSuccess

Arguments

<iLastColumn>The number of the last visible column from which the first visible column is to be determined. The number of the column refers to the list of the opened columns (see also bBrowser:ColumnOpenList).
Data type:Integer

 

<iFirstColumn>The number of the determined first visible column. The number of the column refers to the list of the opened columns (see also bBrowser:ColumnOpenList).

The argument must be specified by reference.

Datentyp:Integer

 

<iOffset>The offset for the determined first visible column related to the left margin of the dynamic data area. The offset can be less or equal 0. If the offset is 0, then the first visible column starts directly on the left margin of the dynamic data area. If the offset is less than 0, then the column is partly concealed by the left margin of the dynamic data area.

The argument must be specified by reference.

Datentyp:Integer

Return Value

lSuccessA logical value that indicates whether the first visible column was determined.
TRUEThe column was determined.
FALSEThe column could not be determined.
Data type:Logic

Description

bBrowser:GetFirstVisibleColumn() determines the first visible column and its offset related to the left margin of the dynamic data area.

 

It is possible that the determined first visible column is not completely visible but is partly concealed by the left margin of the dynamic data area. This depends on the column widths and the width of the visible area in the browser. The number of concealed pixels is then returned in the argument <iOffset> as a negative value.
