/**
* @class Ext.SplitButton
* @extends Ext.Button
* A split button that provides a built-in dropdown arrow that can fire an event separately from the default
* click event of the button. Typically this would be used to display a dropdown menu that provides additional
* options to the primary button action, but any custom handler can provide the arrowclick implementation. Example usage:
*
// display a dropdown menu:
new Ext.SplitButton({
renderTo: 'button-ct', // the container id
text: 'Options',
handler: optionsHandler, // handle a click on the button itself
menu: new Ext.menu.Menu({
items: [
// these items will render as dropdown menu items when the arrow is clicked:
{text: 'Item 1', handler: item1Handler},
{text: 'Item 2', handler: item2Handler}
]
})
});
// Instead of showing a menu, you provide any type of custom
// functionality you want when the dropdown arrow is clicked:
new Ext.SplitButton({
renderTo: 'button-ct',
text: 'Options',
handler: optionsHandler,
arrowHandler: myCustomHandler
});
var btn = new Ext.CycleButton({
showText: true,
prependText: 'View as ',
items: [{
text:'text only',
iconCls:'view-text',
checked:true
},{
text:'HTML',
iconCls:'view-html'
}],
changeHandler:function(btn, item){
Ext.Msg.alert('Change View', item.text);
}
});
