Summary0006771: JvCheckTreeView: various problems
DescriptionWorking with Delphi 12.0

Adding a JvCheckTreeView component to a form and adding an item to it, at design time, causes the program to crash at runtime.

Working with Delphi 11.3

I was trying to disable the ability to check or uncheck checkboxes in a JvCheckTreeView.
The ReadOnly property only disables item caption editing.
It seems to me that the OnToggled, OnToggling, OnCheckStateChanged and OnCheckStateChanging events never fire.
I also found that the onChanging event fires when a new item is selected, but setting AllowChange := False doesn't prevent the change.

Just for the record I found a solution to my problem using the OnNodeCheckedChange event, by toggling the event before and after assigning the old state of the checkbox; not very easy...
Steps To ReproduceI attach a sample program
