ok := dialog.Message("%s", "Do you want to continue?").Title("Are you sure?").YesNo()
Creates a dialog box titled “Are you sure?”, containing the message “Do you want to continue?”,
a “Yes” button and a “No” button. Returns true iff the dialog could be displayed and the user
pressed the “Yes” button.
Creates a file selection dialog allowing the user to select a .mp3 file. The absolute path of
the file is returned, unless an error is encountered or the user cancels/closes the dialog.
In the latter case, filename will be the empty string and err will equal dialog.Cancelled.
filename, err := dialog.File().Filter("XML files", "xml").Title("Export to XML").Save()
Asks the user for a filename to write data into. If the user selects a file which already exists,
an additional dialog is spawned to confirm they want to overwrite the existing file.
