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()

Implementations

impl<'a> SpacerItem<'a>

pub fn change_size(&self, w: i32, h: i32, h_data: Policy, v_data: Policy) -> &Self

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.
