示例1: CorrectListSize
void ModalListPicker::CorrectListSize() {
// reset size of displayed drop list based on number of shown rows set.
// assumes that all rows have the same height.
// adds some magic padding for now to prevent the scroll bars showing up.
if (!m_relative_to_wnd)
return;
if (LB()->Visible())
return;
LB()->MoveTo(Pt(m_relative_to_wnd->Left(), m_relative_to_wnd->Bottom()));
Pt drop_down_size(m_relative_to_wnd->DroppedRowWidth(), m_relative_to_wnd->ClientHeight());
if (LB()->Empty()) {
LB()->Resize(drop_down_size);
} else {
LB()->Show();
// The purpose of this code is to produce a drop down list that
// will be exactly m_num_shown_rows high and make sure that the
// selected row is prerendered in the same way when the drop down
// list is open or closed.
// The list needs to be resized twice. The first resize with an
// estimated row height will add any list box chrome, like scroll
// bars to the list and may change the height of the row. The
// second resize uses the corrected row height to finalize the drop
// down list size.
// Note: Placing a tighter constraint on valid DropDownList rows
// of always returning the same fixed height regardless of status
// (width, prerender etc.) would mean this code could be reduced to
// check height and resize list just once.
drop_down_size = DetermineListHeight(drop_down_size);
DetermineListHeight(drop_down_size);
LB()->Hide();
}
