var MS = Myna.Swing;
...
    layoutPos:{
        anchor:MS.getConst("GridBagConstraints.WEST"),
        gridwidth:MS.getConst("GridBagConstraints.REMAINDER"),     //end row
        fill:MS.getConst("GridBagConstraints.HORIZONTAL"),  //expand horizontally
        weightx:1.0, // expand to fill extra space
    },
...

alert:function( text, title, type )

Creates an alert dialog

Parameters

getInput:function( prompt, options, defaultIndex )

Displays an input dialog, similar to window.prompt() in the browser

confirm:function( prompt, buttons, defaultIndex )

Displays a confirmation dialog, similar to window.confirm() in the browser

Parameters

Returns

True, if the “OK” button is pressed false, if canceled

showDialog:function( fields, buttonLabels, defaultIndex )

Creates a dialog with arbitrary fields

Parameters

Returns

Array of generated fields, or null if canceled.  If the config objects in fields include the name property, then a property of that name will also be in the returned array.  This means that fields can be referenced by name or index

Example

var result = showDialog([{
    cls:"JLabel",
    text:"Username:"
},{
    cls:"JTextField",
    name:"username"
},{
    cls:"JLabel",
    text:"Password:"
},{
    cls:"JPasswordField",
    name:"password"
}],"SVN Authentication")

if (result){
    p.username = result.username.getText()
    //getPassword returns a char[], so we filter it through a native Java string
    p.password = new java.lang.String(result.password.getPassword()).toString()
    svn = new WebSvn().connect(p.username,p.password);
}

build:function( config )

Creates Swing component from an object config

Parameters

Config

Returns

An extended instance of cls with these extra properties:

Example

var MS = Myna.Swing;
var config = {
    //Special Property: Swing class to create
    cls:"JFrame",
    //any property that has setter is set on the resulting object
    title:"HelloWorldSwing",
    //getConst returns the value of the passed constant Value.
    defaultCloseOperation:$server.isCommandline?MS.getConst("JFrame.EXIT_ON_CLOSE"):MS.getConst("WindowConstants.DISPOSE_ON_CLOSE"),
    //any property not already defined by the class, will be added to the resulting object
    center:function(){
        this.setLocationRelativeTo(null)
    },
    //Special Property: elements to add to this Swing object
    items:[{
        cls:"JPanel",

        //Special Property: layout specific positioning hint for this control
        layoutPos:MS.getConst("BorderLayout.CENTER"),
