Chapter 10. Controlling Text > Controlling Text Box Scrolling

Controlling Text Box Scrolling

When the information in multiline input text or dynamic text exceeds the defined boundaries of the text box, Flash automatically scrolls the text so that the currently input text remains visible. Rows of text that can't fit within the text box are hidden from view but still accessible by the viewer by clicking inside the text box and dragging the cursor up or down . You can dynamically display different rows of text, whether they are hidden or not, by controlling the position of the first visible row of text in a text box. This property is called scroll. The top row has the value of 0, and as new lines of text scroll up or down, that value changes (Figure 10.28).

Figure 10.28. The scroll property is the first visible row of text.
