Some simple but Handy Extensions

General
1

I recently found I was trying to dynamically position a bunch of controls and was constantly adding the left+width or finding the centers, and in doing so was duplicating the same basic equations over and over. Then I recalled that Swift has methods attached to all the controls that return these values directly… so I created these simple extends for the RECTCONTROL. And since almost all controls inherit from RECTCONTROL… just adding this code to your project will add these functions to every control you are using.

Some are just an alias for existing properties, some have a tiny bit of math, all should be self explanitory

Public Function minX(Extends ctl as Rectcontrol) as integer
  Return ctl.Left
End Function

Public Function maxX(Extends ctl as Rectcontrol) as integer
  Return ctl.Left+ctl.width
End Function

Public Function maxY(Extends ctl as Rectcontrol) as integer
  Return ctl.Top+ctl.Height
End Function

Public Function midX(Extends ctl as Rectcontrol) as integer
  Return ctl.Left+(ctl.width/2)
End Function

Public Function midY(Extends ctl as Rectcontrol) as integer
  Return ctl.Top+(ctl.height/2)
End Function

Public Function minY(Extends ctl as Rectcontrol) as integer
  Return ctl.Top
End Function

Public Function Origin(Extends ctl as Rectcontrol) as REALbasic.Point
  Return New REALbasic.Point(ctl.Left,ctl.top)
End Function

Public Function Size(Extends ctl as Rectcontrol) as REALbasic.Size
  Return New REALbasic.Size(ctl.width,ctl.height)
End Function
