Name

qwarning — information dialog displaying a warning

Syntax

qwarning caption text [button-0-text] [button-1-text] [button-2-text]

Description

The qwarning command displays a read-only warning dialog with one or more buttons, along with a caption. The default is a single 'OK' button. The dialog is modal, therefore execution is halted until the user closes the dialog.

The dialog may optionally have up to three buttons to replace the default OK button. The buttons are implicitly numbered 0, 1, 2. The command will return the number corresponding to the button pressed by the user.

}
