Here you can find out how to change the text displayed to the textArea at runtime using ui methods or DISPLAY ... TO statement.
Here you can find out how to input text to a textArea using the INPUT statement, e.g.:
INPUT BY NAME f1 WITHOUT DEFAULTS
You can change appearance properties of a textArea in Lycia Form Designer. However, we recommend applying appearance properties via user themes and css.
To apply a property to a textArea, set its value in the user theme, directly or using filters.
In the example below, we change the font color of the text displayed to a definite textArea by applying New Font property with a With ID... filter.

runtime appearance |
In the example below, we use css to change the text style of the button:
.qx-aum-text-area .qx-text {
padding: 2px;
padding: 5px 10px;
color: white !important;
font: bold 14px "Calibri","Helvetica Neue", Sans-Serif;
}
At runtime, textAreas can be manipulated with ui methods.
Here you can find out how to enable multiple-lines display or specify the application behavior after pressing the Enter key at runtime using the setAllowNewLines method:
Here you can find out how to specify the application behavior after pressing the Tab key at runtime using the setUseTabs method:
Here you can find out how to set the maximum length for strings input to a field using the setMaxLength method:
Here you can find out how to move input to the next field after the value specified for maxLength is reached using the setAutonext method:
