I can confirm that it does work.

There is only limited information here: https://docwiki.embarcadero.com/Support/en/“ERROR_ITMS-90507:_Missing_Info.plist_value._A_value_for_the_key_'DTPlatformName'_is_required”_when_submitting_an_app_to_the_iOS_App_Store

With no 3rd party installed it is very fast, I get the list instantly. Get a cat, dogs are boring.

Compile the fmx application for windows 32 platform. (Unfortunately) The (only) most stable platform to debug delphi application.

It really depends how many Delphi versions you have to support. The change is documented and was made to make life easier to integrate with other programming languages.

A more details could help. One solution can be to place a panel onto the form where you place your UI controls. If the record is lock set the enabled proprty of the panel to false.

It was a request to change the exception to a proper message before Embarcadero included it in D12. Unfortunately the answer was it is a known limitation of Delphi.

The paint method is to paint on the canvas not to set a property value.

During the Paint method you have to handle csPaintCopy in ControlState (you can check in Vcl.DBCtrls).

The IDE can be strange from time to time. I have a unit that I cannot edit it. If you try to add a property the editor will jump to another line. The only way to edit is to paste the text from another editor. I have tried to create a sample project to reproduce the bug and report it and failed. When I copy the class that fails in the text project I cannot reproduce the bug.

In D12.1 the units I have tested the color is changed after 0-15 seconds.

The ide will generate object Label1: TLabel Left = 303 Top = 233 Width = 99 Height = 15 Caption = #1058#1086' '#1073#1077' '#1086#1088' '#1085#1086#1090' '#1090#1086' '#1073#1077 end

You should see how it is done and Delphi and do it in C++ https://github.com/Embarcadero/Android-Kiosk-Mode-FMXTemplate

I don't have C++, maybe this can help? https://blogs.embarcadero.com/easily-deploy-advanced-android-kiosk-mode-with-this-firemonkey-template/
