示例1: layout
void Fl_Pack::layout()
{
// we only need to do something special if the group is resized:
if (!(layout_damage() & (FL_LAYOUT_WH|FL_LAYOUT_DAMAGE)) || !children())
{
Fl_Group::layout();
if (!(layout_damage() & FL_LAYOUT_DAMAGE))
return;
}
// clear the layout flags, so any resizes of children will set them again:
Fl_Widget::layout();
// This is the rectangle to lay out the remaining widgets in:
int x = 0;
int y = 0;
int r = this->w();
int b = this->h();
box()->inset(x,y,r,b);
bool saw_horizontal = false;
bool saw_vertical = false;
// layout all the top & left widgets (the ones before the resizable):
int i; for (i = 0; i < children(); i++)
{
Fl_Widget* widget = child(i);
if (widget->contains(resizable())) break;
if (!widget->visible()) continue;
if (is_vertical(widget))
{
widget->resize(x, y, widget->w(), b-y);
widget->layout();
x = widget->x() + widget->w() + layout_spacing();
saw_vertical = true;
} // put along top edge:
else
{

widget->layout();
y = widget->y() + widget->h() + layout_spacing();
saw_horizontal = true;
}
}
int resizable_index = i;
// layout all the bottom & right widgets by going backwards:
for (i = children()-1; i > resizable_index; i--)
{

}
// Lay out the resizable widget to fill the remaining space:
if (resizable_index < children())
{

widget->resize(x, y, r-x, b-y);
widget->layout();
}
// A non-resizable widget will become the size of it's items:
