{
gfx::Size size(child->GetPreferredSize());
if(orientation_ == kHorizontal)
{

}
else
{

}
}

}示例2: GetPreferredSize
gfx::Size SingleSplitView::GetPreferredSize()
{
int width = 0;

}
}
if(is_horizontal_)
{
width += kDividerSize;
}

}示例3: Layout
void BoxLayout::Layout(View* host)

}
else
{
bounds.set_height(size.height());
y += size.height() + between_child_spacing_;
}
// Clamp child view bounds to |childArea|.
child->SetBounds(bounds.Intersect(childArea));

}
}示例4: Size
virtual gfx::Size GetPreferredSize(View* host)
{
// First, query the preferred sizes to determine a good width.
int width = 0;
for(int i=0; i<host->child_count(); ++i)
{

width = std::max(width, page->GetPreferredSize().width());
}
// After we know the width, decide on the height.
return gfx::Size(width, GetPreferredHeightForWidth(host, width));
