Detailed Description

The QSpacerItem class provides blank space in a layout.

Normally, you don't need to use this class directly. Qt's built-in layout managers provide the following functions for manipulating empty space in layouts:

Class	Functions
QHBoxLayout	addSpacing(), addStretch(), insertSpacing(), insertStretch()
QGridLayout	setRowMinimumHeight(), setRowStretch(), setColumnMinimumWidth(), setColumnStretch()

Method Documentation

QSpacerItem.init (self, int w, int h, QSizePolicy.Policy hPolicy = QSizePolicy.Minimum, QSizePolicy.Policy vPolicy = QSizePolicy.Minimum)

Constructs a spacer item with preferred width w, preferred height h, horizontal size policy hPolicy and vertical size policy vPolicy.

The default values provide a gap that is able to stretch if nothing else wants the space.

QSpacerItem.init (self, QSpacerItem)

QSpacerItem.changeSize (self, int w, int h, QSizePolicy.Policy hPolicy = QSizePolicy.Minimum, QSizePolicy.Policy vPolicy = QSizePolicy.Minimum)

Changes this spacer item to have preferred width w, preferred height h, horizontal size policy hPolicy and vertical size policy vPolicy.

The default values provide a gap that is able to stretch if nothing else wants the space.

Note that if changeSize() is called after the spacer item has been added to a layout, it is necessary to invalidate the layout in order for the spacer item's new size to take effect.
