示例1: rect
void BComboBox::ChoiceListView::MouseDown(BPoint where)
{
BRect rect(Window()->Frame());
ConvertFromScreen(&rect);
if (!rect.Contains(where))
{
// hide the popup window when the user clicks outside of it
if (fParent->Window()->Lock())
{
fParent->HidePopupWindow();
fParent->Window()->Unlock();
}
// HACK: the window is locked and unlocked so that it will get
// activated before we potentially send the mouse down event in the
// code below. Is there a way to wait until the window is activated
// before sending the mouse down? Should we call
// fParent->Window()->MakeActive(true) here?
if (fParent->Window()->Lock())
{
// resend the mouse event to the textinput, if necessary
BTextView *text = fParent->TextView();
BPoint screenWhere(ConvertToScreen(where));
rect = text->Window()->ConvertToScreen(text->Frame());
if (rect.Contains(screenWhere))
{
//printf(" resending mouse down to textinput\n");
BMessage *msg = new BMessage(*Window()->CurrentMessage());
msg->RemoveName("be:view_where");
text->ConvertFromScreen(&screenWhere);
msg->AddPoint("be:view_where", screenWhere);
text->Window()->PostMessage(msg, text);
delete msg;
}
fParent->Window()->Unlock();
}
return;
}
rect = Bounds();
if (!rect.Contains(where))
return;
fTrackingMouseDown = true;
// check for double click
bigtime_t now = system_time();
bigtime_t clickSpeed;
get_click_speed(&clickSpeed);
if ((now - fClickTime < clickSpeed)
&& ((abs((int)(fClickLoc.x - where.x)) < 3)
&& (abs((int)(fClickLoc.y - where.y)) < 3)))
{
// this is a double click
// XXX: what to do here?
printf("BComboBox::ChoiceListView::MouseDown() -- unhandled double click\n");
}
fClickTime = now;
fClickLoc = where;
float h = LineHeight();
int32 oldIndex = fSelIndex;
fSelIndex = (int32)floor(where.y / h);

if (fSelIndex < 0 || fSelIndex >= choices)
fSelIndex = -1;
if (oldIndex != fSelIndex)
{
InvalidateItem(oldIndex);
InvalidateItem(fSelIndex);
}
// XXX: this probably isn't necessary since we are doing a SetEventMask
// whenever the popup window becomes visible which routes all mouse events
// to this view
// SetMouseEventMask(B_POINTER_EVENTS, B_LOCK_WINDOW_FOCUS);
