The following is fruits of my labors. I am attempting to have a group of two buttons always vertically positioned center-aligned with the hilited line. Here is what I came up with:
on setROControlLoc put the dgHilitedLine of me into tHilitedLine put item 1 of the dgVisibleLines of me into tFirstLine put (tHilitedLine - tFirstLine) into tRowOffset put the top of group "QuickNotes" into tGridTop put the dgProp ["header height"] of me into tHeaderHeight put the dgProp ["row height"] of me into tRowHeight put the loc of group "grpReorder" into tROControlLoc put tGridTop + tHeaderHeight + (tRowHeight * (tRowOffset)) + (tRowHeight /2) into tROControlCenter put tROControlCenter into item 2 of tROControlLoc set the loc of group "grpReorder" to tROControlLoc end setROControlLoc There is probably a much simpler and more elegant wat to go about it, but I can't discern it. I will post a sample stack later. It's pretty cool. The idea is to have a control for moving a line up or down in a datagrid. I considered a drag and drop but it's too much brain power, and this is much easier.
