SetReadonly and TAB

[gab74]

Good morning,
i made a simple map with a button and 2 textedit fields.
The first enable and the second disabled.

Using code i enable the other field when click the button

ui.edtText1->setReadOnly(false);
ui.edtText1->setFocus();

All works and i can write in that field. The cursor when i click the button is set on the field previously disabled.

Problem is that using the TAB key to navigate the 2 fields, the cursor doesen't set on the field enabled by code.
I try to click on the enabled field and the cursor doesen't set on the field at all.
It works only when i click the button.
Why this ?

Thanks Gabriele
