I have a FireMonkey application and I need to change what is selected in Edit1 while the user is typing in Edit2. To be exact, Edit1 has some sample text and Edit2 has a regular expression that the user is editing. I want the user to be able to see if the regular expression is valid and what the matched text would be for the given sample text.
I'm using the OnChangeTracking event of Edit2 to set the SelStart and SelLength of Edit1.
The problem is, unlike VCL's TEdit, FireMonkey's TEdit does not have a HideSelection property, and always hides the selected text if the control does not have the input focus.
Is there a way to change this behavior and force the selection highlight to show no matter which control has input focus?
