1. Delphi Tedit Caret Position
2. Delphi Tedit Get Caret Position

The huge list of fixes for Firemonkey in Delphi 10 Seattle is now available from Embarcadero. There is a pretty impressive list of fixes, upgrades, and enhancements in this latest version. The fixes cover the Android, IOS, OSX, and Windows platforms. Below I’ve highlighting the important fixes that jump out at me and categorized them by type, library, or platform.

Delphi Tedit Caret Position

• Delphi, TEdit text as action trigger. I am using a TEdit to allow the user to enter a number, e.g. I convert the TEdit.Text to an integer and a calculation procedure is called. In this calc procedure, a check was built-in to make sure no numbers below 10 are processed.
• Keyboard input must create the caret when it receives the keyboard focus. Destroy the caret when it loses the keyboard focus. The caret is a shared resource; there is only one caret in the system. Can set the caret position only if it owns the caret. You cannot assume the currently active window has a caret.

I'd like to search for, and then highlight a line or phrase of text in a TMemo. I can get the Caret to move to the start of the correct location via SelStart, but when I set SelLength the selection does not expand visibly. I got two TEdit controls. When I tab out of edit1, edit2 receives the focus. On my OnExit event of Edit1 I have the following code: procedure TForm1.Edit1Exit (Sender: TObject); begin edit2.Enabled:= false; edit2.Enabled:= true; edit2.setfocus; end; Edit2 has the focus. However, there is no caret in it.
