/**
* @class Ext.button.Button
* @extends Ext.Component
Create simple buttons with this component. Customisations include {@link #iconAlign aligned}
{@link #iconCls icons}, {@link #menu dropdown menus}, {@link #tooltip tooltips}
and {@link #scale sizing options}. Specify a {@link #handler handler} to run code when
a user clicks the button, or use {@link #listeners listeners} for other events such as
{@link #mouseover mouseover}.
{@img Ext.button.Button/Ext.button.Button1.png Ext.button.Button component}
Example usage:
Ext.create('Ext.Button', {
text: 'Click me',
renderTo: Ext.getBody(),
handler: function() {
alert('You clicked the button!')
}
});
The {@link #handler} configuration can also be updated dynamically using the {@link #setHandler} method.
Example usage:
Ext.create('Ext.Button', {
text : 'Dyanmic Handler Button',
renderTo: Ext.getBody(),
handler : function() {
//this button will spit out a different number every time you click it.
//so firstly we must check if that number is already set:
if (this.clickCount) {
//looks like the property is already set, so lets just add 1 to that number and alert the user
this.clickCount++;
alert('You have clicked the button "' + this.clickCount + '" times.\n\nTry clicking it again..');
} else {
//if the clickCount property is not set, we will set it and alert the user
this.clickCount = 1;
alert('You just clicked the button for the first time!\n\nTry pressing it again..');
}
}
});
A button within a container:
Ext.create('Ext.Container', {
renderTo: Ext.getBody(),
items : [
{
xtype: 'button',
text : 'My Button'
}
]
});
A useful option of Button is the {@link #scale} configuration. This configuration has three different options:
* `'small'`
* `'medium'`
* `'large'`
{@img Ext.button.Button/Ext.button.Button2.png Ext.button.Button component}
Example usage:
Ext.create('Ext.Button', {
renderTo: document.body,
text : 'Click me',
scale : 'large'
});
Buttons can also be toggled. To enable this, you simple set the {@link #enableToggle} property to `true`.
{@img Ext.button.Button/Ext.button.Button3.png Ext.button.Button component}
Example usage:
Ext.create('Ext.Button', {
renderTo: Ext.getBody(),
text: 'Click Me',
enableToggle: true
});
You can assign a menu to a button by using the {@link #menu} configuration. This standard configuration can either be a reference to a {@link Ext.menu.Menu menu}
object, a {@link Ext.menu.Menu menu} id or a {@link Ext.menu.Menu menu} config blob. When assigning a menu to a button, an arrow is automatically added to the button.
You can change the alignment of the arrow using the {@link #arrowAlign} configuration on button.
{@img Ext.button.Button/Ext.button.Button4.png Ext.button.Button component}
Example usage:
Ext.create('Ext.Button', {
text : 'Menu button',
renderTo : Ext.getBody(),
arrowAlign: 'bottom',
menu : [
{text: 'Item 1'},
{text: 'Item 2'},
{text: 'Item 3'},
{text: 'Item 4'}
]
});
Using listeners, you can easily listen to events fired by any component, using the {@link #listeners} configuration or using the {@link #addListener} method.
Button has a variety of different listeners:
* `click`
* `toggle`
* `mouseover`
* `mouseout`
* `mouseshow`
* `menuhide`
* `menutriggerover`
* `menutriggerout`
Example usage:
Ext.create('Ext.Button', {
text : 'Button',
renderTo : Ext.getBody(),
listeners: {
click: function() {
//this == the button, as we are in the local scope
this.setText('I was clicked!');
},
mouseover: function() {
//set a new config which says we moused over, if not already set
if (!this.mousedOver) {
this.mousedOver = true;
alert('You moused over a button!\n\nI wont do this again.');
}
}
}
});
