I am using FMXPlanner in tests with component Demo and i need delete item with source code to abort operation in some cases. How to delete?
You can just destroy the item.
This code snippet removes all selected items for example:
while TMSFMXPlanner1.SelectedItems.Count > 0 do
TMSFMXPlanner1.SelectedItems[TMSFMXPlanner1.SelectedItems.Count - 1].Free;
