Description

Inserts a column into the specified list browser control. Returns index of created column.
FUNCTION InsertLBColumn(
dialogID  :LONGINT;
componentID  :LONGINT;
columnIndex  :INTEGER;
headerString  :STRING;
width  :INTEGER) : INTEGER;
def vs.InsertLBColumn(dialogID, componentID, columnIndex, headerString, width):
    return INTEGER

Parameters

dialogID LONGINT id of the dialog that contains the list browser
componentID LONGINT id of the list browser control
columnIndex INTEGER index at which the column is to be inserted
headerString STRING text to set as column header
width INTEGER the width of the column in pixels

Remarks

width is specified in pixles

If you recursively use '0' as 'columnIndex' where to insert the new column, all column headers after the second will center the text label. Moreover they cannot be justified any longer.

If you insert an image to the List Browser, the second column header unexpectedly will display an image instead of text.

So don't use recursively zero for creating new columns. The issue disturbs quite a lot if you are loading columns from XML files, since the element reading starts from the end, so you'd like to add the columns always at top of the list.
