QLayout::QLayout ( QWidget * parent, int margin, int spacing = -1, const char * name = 0 )

Constructs a new top-level QLayout called name, with parent widget parent. parent may not be 0.

The margin is the number of pixels between the edge of the widget and the managed children. The spacing sets the value of spacing(), which gives the spacing between the managed widgets. If spacing is -1 (the default), spacing is set to the value of margin.

There can be only one top-level layout for a widget. It is returned by QWidget::layout()

QLayout::QLayout ( QLayout * parentLayout, int spacing, const char * name = 0 )

Constructs a new child QLayout called name, and places it inside parentLayout by using the default placement defined by addItem().

If spacing is -1, this QLayout inherits parentLayout's spacing(), otherwise the value of spacing is used.

QLayout::QLayout ( int spacing, const char * name = 0 )

Constructs a new child QLayout called name. If spacing is -1, this QLayout inherits its parent's spacing(); otherwise the value of spacing is used.

This layout has to be inserted into another layout before geometry management will work.
