示例1: selection
// SetTo
void
PropertyListView::SetTo(PropertyObject* object)
{
// try to do without rebuilding the list
// it should in fact be pretty unlikely that this does not
// work, but we keep being defensive
if (fPropertyObject && object &&
fPropertyObject->ContainsSameProperties(*object)) {
// iterate over view items and update their value views
bool error = false;
for (int32 i = 0; PropertyItemView* item = _ItemAt(i); i++) {
Property* property = object->PropertyAt(i);
if (!item->AdoptProperty(property)) {
// the reason for this can be that the property is
// unkown to the PropertyEditorFactory and therefor
// there is no editor view at this item
fprintf(stderr, "PropertyListView::_SetTo() - "
"property mismatch at %ld\n", i);
error = true;
break;
}
if (property)
item->SetEnabled(property->IsEditable());
}
// we didn't need to make empty, but transfer ownership
// of the object
if (!error) {
// if the "adopt" process went only halfway,
// some properties of the original object
// are still referenced, so we can only
// delete the original object if the process
// was successful and leak Properties otherwise,
// but this case is only theoretical anyways...
