A textbox is used to let users input textual data.

You could assign value, type, constraint, rows, cols to a textbox using the corresponding properties. When you assign the property type to a string value "password" when multiline is false (multiline will be true if you set rows larger than 1 or set multiline to true directly) then any character in this component will replace by '*'.

You could also assign a constraint value with a regular expression string or a default constraint expression (available value is "no empty"). When user change the value of textbox, it will cause a validating process to validate the value. If the validation fails, then a notification will pop up.

<textbox value="text..." />
<textbox value="secret" type="password" />
<textbox constraint="/.+@.+\.[a-z]+/: Please enter an e-mail address" />
<textbox rows="5" cols="40">
	<attribute name="value">
text line1... 
text line2...

To specify multilines value, you can use the attribute element or &#x0d; as shown below

<textbox rows="5" cols="40">
	<attribute name="value">
text line1... 
text line2...
<textbox value="Line 1&#x0d;Line 2" rows="3"/>



By specifying a true, the tabbox can insert a long space or format the content inside textbox conveniently. For example,

<textbox tabbable="true"/>


Since 8.5.2

When you specify true, pressing Enter will fire onOK event rather then move to next line, if you want to move to next line, you should press Shift + Enter.

When submitByEnter="false", press Enter will move to next line.

The default is false.

<textbox submitByEnter="true" onOK=""/>


The type attribute can be used with the textbox based components and can be given the value password. By setting the type as password the text that is entered into the box cannot be viewed and is replaced by stars.

Username: <textbox/>
Password: <textbox type="password"/>
Since  6.5.0

The type attribute support HTML 5 defined types tel, email and url.
