## Member Function Documentation

### Q3HBoxLayout::Q3HBoxLayout ( QWidget * parent, int margin, int spacing = -1, const char * name = 0 )

Constructs a new top-level horizontal box called name, with parent parent. The margin is the number of pixels between the edge of the widget and its managed children. The spacing is the default number of pixels between neighboring children. If spacing is -1 the value of margin is used for spacing.

### Q3HBoxLayout::Q3HBoxLayout ( QLayout * parentLayout, int spacing = -1, const char * name = 0 )

Constructs a new horizontal box called name and adds it to parentLayout. The spacing is the default number of pixels between neighboring children. If spacing is -1, this Q3HBoxLayout will inherit its parent's spacing.

### Q3HBoxLayout::Q3HBoxLayout ( int spacing, const char * name = 0 )

Constructs a new horizontal box called name. You must add it to another layout. The spacing is the default number of pixels between neighboring children. If spacing is -1, this QHBoxLayout will inherit its parent's spacing().
