Adding an icon

A button can have an icon which is set through the corresponding option icon:

{
    type:"button", value:"Done",
    icon:"dxi dxi-check"
}

Adding a badge with a number

You can add a number badge to the button to display information like the number of new messages. The badge is set via the count property:

{
    type:"button", value:"Done",
    icon:"dxi dxi-check",
    count:10
}

Showing/hiding a button

To hide/show a button, you should pass the ID of the button to the hide() / show() Toolbar methods:

toolbar.show(id);
toolbar.hide(id);

Enabling/disabling a button

Any button in the toolbar can be enabled/disabled:

toolbar.enable(id);
toolbar.disable(id);

Setting tooltip

You can add a tooltip to a button:

{
    type:"button", 
    value:"Click", 
    tooltip:"Click me and find out why"  }

Two state buttons

You can create buttons with two states: active (pressed) and inactive (unpressed). The activity of a two state button is controlled via the active attribute of the Button object:

{
    type:"button", 
    value:"Select", 
    twoState:true, active:true  }

Changing state of a two state button on the fly

The state of a two state button can be changed programmatically with the setState() method of Toolbar as in:

{
    type:"button", twoState:true, value:"Check", id:"check"
}
...
toolbar.setState({"check":true});    // active:true  // or
toolbar.setState({"check":false});   // active:false

setState() accepts one parameter: a key-value pair with the ID of the button and the new value.

Accessing current state of a two state button

The current state of a two state button can be checked with the getState() method:

{
    type:"button", value:"Check", twoState:true, id:"check"
}
...
var state = toolbar.getState(); // -> { check:true } or { check:false }
