CustomDrawItem/SubItems

Folks,

I need to draw the SubItems of a listview manually. My Problem is, how to determine the leftposition of a subitem (i'm currently doing this with the columns-property of the listview).
Now, when the user resizes one of the columns, the width-property of the Column in Columns property is not updated and the Subitem (TextOut()) is drawn on a wrong position.

I'm using OnCustomDrawSubItem. Everything works except the drawing while the user resizes a column.

Please help!
Thanks, Bruno

Looks like a bug in VCL. Try to avoid using the Columns when you need the width and use instead the LVM_GETCOLUMNWIDTH message like this:

theColumnWidth:=SendMessage(YourListView.Handle,LVM_GETCOLUMNWIDTH,theColumnIndex,0);
