Many thanks! It seems that the following call was the key to my problem:
m_TextView.set_expand();
This call seems very non-intuitive to me; I would have expected the
TextView to automatically expand

A concise description of the problem is this:
If I make the TextView a child of the window, the text is displayed. If I

You have declared the TextView as a local variable in the constructor.
It will be deleted when the constructor finishes. You must either

I am trying to add a TextView instance to a Grid. But when I display the
window, it is
empty. The Grid examples I have seen add buttons to the grid and these work
fine
for me. But I don't understand the difference between adding a button and
adding
a TextView. If anyone can help me with this, I wou
