Dynamically Creating Controls in Palm OS


Creating controls in Palm OS is very useful. It gives vital power to the programmer in creating applications. There are various controls in Palm OS like buttons, check boxes, radio buttons, lists, text boxes, lists, etc. Buttons, check boxes, and radio buttons can be created dynamically using the following API:
 
CtlNewControl(void **formPP,
UInt16 ID, ControlStyleType style,
const Char *textP, Coord x, Coord y, Coord width,
Coord height, FontID font, UInt8 group,
Boolean leftAnchor)

The control style type tells the type of control, Text Boxes can be dynamically created with FldNewField, and lists can be dynamically created with LstNewList.
