Member Function Documentation

◆ addItem()

void QToolBarLayout::addItem ( QLayoutItem * item)
overridevirtual

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.

◆ checkUsePopupMenu()

◆ count()

int QToolBarLayout::count ( ) const
overridevirtual

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

See also
itemAt()

Implements QLayout.

Definition at line 184 of file qtoolbarlayout.cpp.

◆ expandedSize()

QSize QToolBarLayout::expandedSize ( const QSize & size) const

Definition at line 551 of file qtoolbarlayout.cpp.

◆ expandingDirections()

Qt::Orientations QToolBarLayout::expandingDirections ( ) const
overridevirtual

Returns whether this layout can make use of more space than sizeHint().

A value of Qt::Vertical or Qt::Horizontal means that it wants to grow in only one dimension, whereas Qt::Vertical | Qt::Horizontal means that it wants to grow in both dimensions.

The default implementation returns Qt::Horizontal | Qt::Vertical. Subclasses reimplement it to return a meaningful value based on their child widgets's \l{QSizePolicy}{size policies}.

Since
5.12 Searches for layout item layoutItem in this layout (not including child layouts).

Returns the index of layoutItem, or -1 if layoutItem is not found.

Reimplemented from QLayout.

Definition at line 101 of file qlayout.cpp.

◆ indexOf() [3/3]

int QLayout::indexOf ( const QWidget * widget) const
virtual

Searches for widget widget in this layout (not including child layouts).

Returns the index of widget, or -1 if widget is not found.

The default implementation iterates over all items using itemAt().

◆ itemAt()

QLayoutItem * QToolBarLayout::itemAt ( int index) const
overridevirtual

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.

{
QLayout *layout = item->layout();
if (layout) {
for (int i = 0; i < layout->count(); ++i)
paintLayout(painter, layout->itemAt(i));
}
painter->drawRect(item->geometry());
}
{
if (layout())
}

◆ layoutActions()

bool QToolBarLayout::layoutActions ( const QSize & size)

Definition at line 403 of file qtoolbarlayout.cpp.

◆ minimumSize()

QSize QToolBarLayout::minimumSize ( ) const
overridevirtual

Returns the minimum size of this layout.

This is the smallest size that the layout can have while still respecting the specifications.

The returned value doesn't include the space required by QWidget::setContentsMargins() or menuBar().

The default implementation allows unlimited resizing.

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

Implements QLayoutItem.

Definition at line 671 of file qtoolbarlayout.cpp.

◆ takeAt()

QLayoutItem * QToolBarLayout::takeAt ( int index)
overridevirtual

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:

while ((child = layout->takeAt(0)) != nullptr) {
...
delete child->widget(); // delete the widget
delete child; // delete the layout item
}
