Member Function Documentation

◆ addItem()

void MyLayout::addItem ( QLayoutItem * item )

inlineoverridevirtual

Implemented in subclasses to add an item. How it is added is specific to each subclass.

This function is not usually called in application code. To add a widget to a layout, use the addWidget() function; to add a child layout, use the addLayout() function provided by the relevant QLayout subclass.

{Note:} The ownership of item is transferred to the layout, and it's the layout's responsibility to delete it.

See also: addWidget(), QBoxLayout::addLayout(), QGridLayout::addLayout()

Implements QLayout.

Definition at line 229 of file tst_qlayout.cpp.

◆ count()

int MyLayout::count ( ) const

inlineoverridevirtual

Must be implemented in subclasses to return the number of items in the layout.

See also: itemAt()

Implements QLayout.

Definition at line 232 of file tst_qlayout.cpp.

◆ invalidate()

virtual void MyLayout::invalidate ( )

inlineoverridevirtual

\reimp

Reimplemented from QLayout.

Definition at line 226 of file tst_qlayout.cpp.

◆ itemAt()

QLayoutItem* MyLayout::itemAt ( int index ) const

inlineoverridevirtual

Must be implemented in subclasses to return the layout item at index. If there is no such item, the function must return \nullptr. Items are numbered consecutively from 0. If an item is deleted, other items will be renumbered.

This function can be used to iterate over a layout. The following code will draw a rectangle for each layout item in the layout structure of the widget.

See also: count(), takeAt()

Implements QLayout.

Definition at line 230 of file tst_qlayout.cpp.

◆ sizeHint()

QSize MyLayout::sizeHint ( ) const

inlineoverridevirtual

Implemented in subclasses to return the preferred size of this item.

Implements QLayoutItem.

Definition at line 228 of file tst_qlayout.cpp.

◆ takeAt()

QLayoutItem* MyLayout::takeAt ( int index )

inlineoverridevirtual

Must be implemented in subclasses to remove the layout item at index from the layout, and return the item. If there is no such item, the function must do nothing and return 0. Items are numbered consecutively from 0. If an item is removed, other items will be renumbered.

The following code fragment shows a safe way to remove all items from a layout:
