示例1: BFile
PersonView::PersonView(const char* name, const char* categoryAttribute,
const entry_ref *ref)
:
BGridView(),
fLastModificationTime(0),
fGroups(NULL),
fControls(20, false),

fSaving(false)
{
SetName(name);
SetFlags(Flags() | B_WILL_DRAW);
fRef = ref;
BFile* file = NULL;
if (fRef != NULL)
file = new BFile(fRef, B_READ_ONLY);
// Add picture "field", using ID photo 35mm x 45mm ratio
fPictureView = new PictureView(70, 90, ref);
BGridLayout* layout = GridLayout();
float spacing = be_control_look->DefaultItemSpacing();
layout->SetInsets(spacing, spacing, spacing, spacing);
layout->AddView(fPictureView, 0, 0, 1, 5);
layout->ItemAt(0, 0)->SetExplicitAlignment(
BAlignment(B_ALIGN_CENTER, B_ALIGN_TOP));
if (file != NULL)
file->GetModificationTime(&fLastModificationTime);
delete file;
