Vaadin-Text Area

Common features

All of the features that are available in the Text field and shared input field are available in vaadin-text area. Let’s discuss them one by one.

🍁 Placeholder

The brief description of the anticipated input value is a placeholder. Only when the text field is empty is it displayed.

TextField textField = new TextField();
textField.setEnabled(false);
textField.setLabel("Disabled");
textField.setValue("Value");
add(textField);

🍁 Clear button

The field's current value is erased by the optional clear button. While the field is empty, it is hidden. For search and filter fields, where it is often for the user to want to clear the field value, clear buttons are helpful.

TextField textField = new TextField();
textField.setClearButtonVisible(true);
textField.setValue("Coding ninjas");
add(textField);

🍁 Text Alignment

Left (the default), center, and right are the three text alignment options that are provided.

When displayed in vertical groups, numerical values should be right-aligned as this makes it simpler to understand and contrast values.

TextField right = new TextField();
right.setValue("right");
right.addThemeVariants(TextFieldVariant.LUMO_ALIGN_RIGHT);

🍁 Min and Max Input Length

By limiting text entry to the maximum length and causing a validation error if a shorter value than the minimum length is provided, these parameters have an impact on the smallest and largest number of characters a field can allow.
 

TextField zipCode = new TextField();
zipCode.setMinLength(5);
zipCode.setMaxLength(5);
zipCode.getStyle().set("width", "6em");
zipCode.setLabel("Zip code");
add(zipCode);

TextField username = new TextField();
username.setMaxLength(16);
username.setHelperText("Max 16 characters");
username.setLabel("Username");
add(username);

🍁 Pattern

We can define the pattern that the input must follow (using regular expressions) in order to prevent the user from submitting a false value.

TextField = new TextField();
textField.setPattern("^[+]?[(]?[0-9]{3}[)]?[-s.]?[0-9]{3}[-s.]?[0-9]{4,6}$");
textField.setHelperText("Format: +(123)456-7890");
textField.setLabel("Phone number");
add(textField);

Character Counter

Free-form inputs that are longer than a specified character limit are frequently capped. The user should be informed of the current character limit and maximum character count.

TextArea textArea = new TextArea();
textArea.setWidthFull();
textArea.setLabel("Description");
textArea.setMaxLength(charLimit);
textArea.setValueChangeMode(ValueChangeMode.EAGER);
textArea.addValueChangeListener(e -> {
  e.getSource().setHelperText(e.getValue().length() + "/" + charLimit);
});
textArea.setValue(loremIpsum);
add(textArea);
