SCAlert

part of wslib

An alert window class

Note: not yet SwingOSC compatible

SCAlert( "Are you alerted now?", [ "No", "Yes" ] );

creation:

SCAlert( string, buttons, actions, color, background, iconName, border )

string : a string containing the message to be displayed. You can use $\n characters in it as well

buttons : an Array containing the names of the buttons. It can also contain SCButton states.

buttons defaults to [ "cancel", "ok" ]

actions : an Array containing a function for each button

color : the color of the border stripe around the window and the icon. Defaults to Color.red.alpha_(0.75)

background : the background color of the window. Defaults to white

iconName : the name of the icon to be displayed from DrawIcon. Defaults to 'warning'

border : Should the window have a border? Defaults to true

SCAlert also listens to key strokes. If you type a letter it will find the button of which the name starts with that letter and hit it (just like in most alert windows).
