CalloutFormat.Drop Property (PowerPoint)
For callouts with an explicitly set drop value, this property returns the vertical distance (in points) from the edge of the text bounding box to the place where the callout line attaches to the text box. Read-only.
expression A variable that represents a CalloutFormat object.
The distance is measured from the top of the text box unless the AutoAttach property is set to True and the text box is to the left of the origin of the callout line (the place that the callout points to). In this case the drop distance is measured from the bottom of the text box.
Use the CustomDrop method to set the value of this property.
The value of this property accurately reflects the position of the callout line attachment to the text box only if the callout has an explicitly set drop value — that is, if the value of the DropType property is msoCalloutDropCustom.
This example replaces the custom drop for shape one on
myDocument with one of two preset drops, depending on whether the custom drop value is greater than or less than half the height of the callout text box. For the example to work, shape one must be a callout.
Set myDocument = ActivePresentation.Slides(1) With myDocument.Shapes(1).Callout If .DropType = msoCalloutDropCustom Then If .Drop < .Parent.Height / 2 Then .PresetDrop msoCalloutDropTop Else .PresetDrop msoCalloutDropBottom End If End If End With
