Properties
autofocus → bool
Auto-focus when opened (used when a DBGrid Tab enters this cell)
final
colWidths → List <double
Per-column width (px) for the multi-column case
final
dataSet → TSQLQuery ?
Dataset-driven (alternative to lookupColumns): pass the dataset +
key field + display fields directly, and WapLookupBox calls
dataSet.lookupMap(keyField, displayFields) itself to compute the list.
Corresponds to Delphi's TDBLookupComboBox.ListSource/KeyField/ListField.
final
displayFields → List <String ?
final
forGrid → bool
true → DBGrid cell mode: no border, Enter/Tab keyboard handling enabled
final
hashCode → int
The hash code for this object.
no setter inherited
height → double
Height (defaults to 28 for standalone fields; fills the cell when forGrid)
final
key → Key ?
Controls how one widget replaces another widget in the tree.
final inherited
keyField → String ?
final
lookupColumns → Map <String List <String ?
Multi-column lookup: key → col1, col2, ...
final
lookupItems → Map <String String ?
Single-column lookup: key → display string
final
onChanged → ValueChanged <String ?
Callback on selection or fill-back on blur (passes the key)
final
onPicked → ValueChanged <String ?
Callback when a dropdown item is picked (distinct from onChanged:
onChanged = typing, onPicked = picking from the list)
final
onTab → VoidCallback ?
DBGrid cell: Tab → next cell
final
onTabPrev → VoidCallback ?
DBGrid cell: Shift+Tab → previous cell
final
readOnly → bool
Read-only (locked while a standalone field is not in edit state)
final
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
tapRegionGroupId → String ?
TextFieldTapRegion group id (standalone fields can share one, to avoid
taps on one blurring another)
final
textStyle → TextStyle ?
Text style (a DBGrid cell can pass a style matching the rest of the table)
final
value → String
Current value (key)
final
width → double
Field width (for standalone fields; ignored and filled to the cell when forGrid=true)
