Salve,
voglio chiudere la finestra Notifier.ShowPassworDialog o Notifier.ShowTextDialog dopo x secondi tramite un timer, come posso fare?
grazie.
You can do it with these extensions:
maybe there are others ?
Ciao, proseguo in inglese così chiunque può leggere e correggere / modificare / suggerire ecc. 
Anyway if you prefer to read in Italian, please let me know, so I'll send some notes in Italian as well.
Everything that has already said @TIMAI2 is perfect, but, since I've faced similar problems with the standard Notifiers, I've written in the past a possible solution without the use of any extension, just by using blocks (and a timer).
The main rationale is to display/hide a vertical arrangement that behaves like a popup (i.e. a Notifier). In the middle of the screen a Vertical arrangement that acts as a Notifier remains hidden, and it appears only when it is requested. In my example when the button in the upper half of the screen is hit.
The lower half of the screen is fitted with another vertical layout that contains a debug label and the EXIT button.
When the PopUp is displayed the screen appears like the following:
You can then enter the text (single line in my example) and accept or discard it.
If you accept, the input text is mirrored into the label in the lower half screen, otherwise if you discard it, or the 5 seconds (trimmable) timeout elapses, the NO INPUT message is shown.
The example is an "example only" (obviously
) therefore you can use it as an idea on how to create your own Notifier that disappears after a while if not filled.The two halves (upper and lower) of the screen in my example are almost empty, but in your app you shall fill them with your labels, buttons, etc. that is your app's struff. The trick to have two TextBoxes is due to the fact that before leaving the TextBox1, is better to move the focus to another textbox, so to allow the very last input entered in TextBox1 (a character or a row) to be stored into the global variable. If the TextBox1 remains with the focus, the last input is not transferred. To avoid this behaviour, when leaving the TextBox1, I force the focus to another TextBox (2) which has the properttis "enabled" and "visible" set to ON but effectively not visible due to its dimensions (10x1 pixels) I use this second txt box just as a spacer between the two buttons.
Last comment: in the example the custom notifier is shown in the middle, but you can decide to show it wherever you want in your app's layout (top, bottom, else...)
Very last comment: if you want much better visual effects, you can use an extension from @VSATISH13 , called OverlapView that allows you to create "real" pop-ups You can find it here:
Here below my blocks (you'll find them in the annexed .aia)
