as you can read, i've a strange behaviour...
I've a form with some button and one QLineEdit; when i tap on it, keyboard is shown well;
but, if i click on a button of the form, that shows another form on it (created within the constructor without a parent as parameter) and then i close it,
if i tap again on the QLineEdit it doesn't show the keyboard!
If it contains a text, with a tap on it the text is selected, but it seems readonly; if i close the form and reopen it, all work again!
In the code there isn't any instruction for disable it...
Thanks for the help
