An attributed string proxy manages character strings and associated sets of attributes (for example, font and foregroundcolor) that apply to individual characters or ranges of characters in the string.
The AttributedString proxy is created with the Titanium.UI.createAttributedString method.
The text property must be set initially in the constructor when creating an attributed string.
The attributes can either be set in the constructor or after it has been created.
For examples of Attributed Strings, see the Attributed Strings guide.
Creates an AttributedString proxy, adds some attributes to it, and applies them to a Titanium.UI.Label.
var win = Titanium.UI.createWindow({
backgroundColor: '#ddd',
});
win.open();
var text = 'Bacon ipsum dolor Appcelerator Titanium rocks! sit amet fatback leberkas salami sausage tongue strip steak.';
var attr = Titanium.UI.createAttributedString({
text: text,
attributes: [
// Underlines text
{
type: Titanium.UI.ATTRIBUTE_UNDERLINES_STYLE,
value: Ti.UI.ATTRIBUTE_UNDERLINE_STYLE_SINGLE,
range: [text.indexOf('Titanium'), ('Titanium').length]
},
// Sets a background color
{
type: Titanium.UI.ATTRIBUTE_BACKGROUND_COLOR,
value: "red",
range: [text.indexOf('Appcelerator'), ('Appcelerator').length]
},
{
type: Titanium.UI.ATTRIBUTE_BACKGROUND_COLOR,
value: "blue",
range: [text.indexOf('Titanium'), ('Titanium').length]
},
{
type: Titanium.UI.ATTRIBUTE_BACKGROUND_COLOR,
value: "yellow",
range: [text.indexOf('rocks!'), ('rocks!').length]
},
// Sets a foreground color
{
type: Titanium.UI.ATTRIBUTE_FOREGROUND_COLOR,
value: "orange",
range: [0, text.length]
},
{
type: Titanium.UI.ATTRIBUTE_FOREGROUND_COLOR,
value: "black",
range: [text.indexOf('rocks!'), ('rocks!').length]
}
]
});
var label = Titanium.UI.createLabel({
left: 20,
right: 20,
height: Titanium.UI.SIZE,
attributedString: attr
});
win.add(label);
var win = Titanium.UI.createWindow({
backgroundColor: '#ddd',
});
win.open();
var text = 'Bacon ipsum dolor Appcelerator Titanium rocks! sit amet fatback leberkas salami sausage tongue strip steak.';
var attr = Titanium.UI.createAttributedString({
text: text
});
// Underlines text
attr.addAttribute({
type: Titanium.UI.ATTRIBUTE_UNDERLINES_STYLE,
range: [0, text.length]
});
var label = Titanium.UI.createLabel({
left: 20,
right: 20,
height: Titanium.UI.SIZE,
attributedString: attr
});
win.add(label);The name of the API that this proxy corresponds to.
The name of the API that this proxy corresponds to.
The value of this property is the fully qualified name of the API. For example, Button
returns Ti.UI.Button.
An array of attributes to add.
An array of attributes to add.
Internally, this calls the addAttribute method for each of the attributes passed in.
Indicates if the proxy will bubble an event to its parent.
Some proxies (most commonly views) have a relationship to other proxies, often established by the add() method. For example, for a button added to a window, a click event on the button would bubble up to the window. Other common parents are table sections to their rows, table views to their sections, and scrollable views to their views. Set this property to false to disable the bubbling to the proxy's parent.
Default: true
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
The Window or TabGroup whose Activity lifecycle should be triggered on the proxy.
If this property is set to a Window or TabGroup, then the corresponding Activity lifecycle event callbacks will also be called on the proxy. Proxies that require the activity lifecycle will need this property set to the appropriate containing Window or TabGroup.
The text applied to the attributed string.
The text applied to the attributed string.
The text property must be set in the constructor and cannot be changed.
Adds the specified callback as an event listener for the named event.
Name of the event.
Callback function to invoke when the event is fired.
Applies the properties to the proxy.
Properties are supplied as a dictionary. Each key-value pair in the object is applied to the proxy such that myproxy[key] = value.
A dictionary of properties to apply.
Fires a synthesized event to any registered listeners.
Name of the event.
A dictionary of keys and values to add to the Titanium.Event object sent to the listeners.
Removes the specified callback as an event listener for the named event.
Multiple listeners can be registered for the same event, so the
callback parameter is used to determine which listener to remove.
When adding a listener, you must save a reference to the callback function in order to remove the listener later:
var listener = function() { Ti.API.info("Event listener called."); }
window.addEventListener('click', listener);
To remove the listener, pass in a reference to the callback function:
window.removeEventListener('click', listener);
Name of the event.
Callback function to remove. Must be the same function passed to addEventListener.
Sets the value of the attributes property.
New value for the property.
Sets the value of the bubbleParent property.
New value for the property.
Sets the value of the lifecycleContainer property.
New value for the property.
