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.
Arguments
caption
text
button-x-text

# Cancel buttons was pressed
} elseif { $button == 2 } {
