Single-line textbox gadget. Can align text both vertically and horizontally in different ways. The gadget gains this functionality by inheriting from the Label class. However, if the amount of text exceeds the dimensions of the gadget, the gadget will ignore its horizontal alignment settings and switch to left-aligned instead. This ensures that moving the cursor over the text will scroll through it correctly.
