## Feedback

To send feedback, follow the directions in the Feedback Page.

Zenity is a rewrite of gdialog, the GNOME port of dialog which allows you to display dialog boxes from the commandline and shell scripts.

## Introduccion

Zenity enables you to create the following types of simple dialog:

- Calendièr

- Seleccion de fichièrs

- Tièra

- Icòna de notificacion

- Messatge

  - Error

  - Entresenhas

  - Question

  - Alèrta

- Avançament

- Text entry

- Text information

## Utilizacion

When you write scripts, you can use Zenity to create simple dialogs that interact graphically with the user, as follows:

- You can create a dialog to obtain information from the user. For example, you can prompt the user to select a date from a calendar dialog, or to select a file from a file selection dialog.

- You can create a dialog to provide the user with information. For example, you can use a progress dialog to indicate the current status of an operation, or use a warning message dialog to alert the user.

When the user closes the dialog, Zenity prints the text produced by the dialog to standard error.

When you write Zenity commands, ensure that you place quotation marks around each argument.

For example, use:

    zenity --calendar --title="Holiday Planner"

Do not use:

    zenity --calendar --title=Holiday Planner

If you do not use quotation marks, you might get unexpected results.

### Access Keys

An access key is a key that enables you to perform an action from the keyboard rather than use the mouse to choose a command from a menu or dialog. Each access key is identified by an underlined letter on a menu or dialog option.

Some Zenity dialogs support the use of access keys. To specify the character to use as the access key, place an underscore before that character in the text of the dialog. The following example shows how to specify the letter 'C' as the access key:

    "_Causissètz un nom".

### Exit Codes

Zenity returns the following exit codes:

Exit Code | Descripcion
--- | ---
`0` | The user has pressed either OK or Close.
`1` | The user has either pressed Cancel, or used the window functions to close the dialog.
`-1` | An unexpected error has occurred.
