Why does TSynEdit not detect Tab key pressed?

Question

This is my first question, I hope it will be a well constructed one.

I'm currently using Delphi 10.4 Community Edition and I installed SynEdit through the GetIt Package Manager.

The problem I'm facing is the following: I created a VCL form, dropped a TSynEdit in it and launched the application. The problem is that if I press the TAB or SHIFT+TAB, nothing happens. I tried to put breakpoints in the following methods of TSynEdit:

• CommandProcessor
• ExecuteCommand
• DoTabKey

and the debugger never enters them while pressing those keys.

I then looked at the Keystrokes property of my TSynEdit control and, although the keystroke for TAB is defined, I think that the shortcut is "fake". What I mean is that if I try to modify what is associated to the ecTab command and manually choose the shortcut value, nor Tab or Shift+Tab are present in the listbox.

Did anyone ever experienced a problem like this? If so, how did you manage to solve it?

PS: Indentation works with other shortcuts, such as CTRL+SHIFT+I/U.

Answer 1

As indicated by Keith Miller, it was as simple as setting to True the property WantTabs for the TSynEdit control.

Still, if anyone knows why the TAB and SHIFT+TAB shortucts don't appear in the listbox of selectable shortcuts, please let us know.
