protoLabelInputLine 8
This proto defines a view that features a label, accepts any kind of input, and is
left-justified. The
protoLabelInputLine can optionally include a picker.
When the protoLabelInputLine does include a picker, the user selects a
choice from the picker. That choice is entered as the text in the input line, and is
marked with a check mark in the picker.
Figure 8-2 shows an example of a protoLabelInputLine with and without the
picker option:
Figure 8-2 An example of a protoLabelInputLine
The protoLabelInputLine is based on a view of the clParagraphView
class. It has two child views:
■ The labelLine child view uses the protoStaticText proto to create the
static text label and to activate the picker if the proto includes one.
■ The entryLine child view uses the protoInputLine proto to create the
input field into which the user writes text. The text value entered into this field is
stored in the
text slot of this view.
You can have your label input line protos remember a list of recent items. To do
this, assign a symbol that incorporates your developer signature to the
'memory
slot of your prototype. The system automatically maintains the list of recent
items for your input line. To access the list, use the same symbol with the
AddMemoryItem , AddMemoryItemUnique , GetMemoryItems , and
GetMemorySlot functions, which are described in “Utility Functions” (page 26-1).
