void tgui::BoxLayout::add ( const tgui::Widget::Ptr widget,
const sf::String &  widgetName = "" 
)
overridevirtual

Adds a widget at the end of the layout.

Parameters
widgetPointer to the widget you would like to add
widgetNameAn identifier to access to the widget later

The widget will have ratio 1.

Reimplemented from tgui::Container.

◆ addSpace()

void tgui::BoxLayout::addSpace ( float  ratio = 1)

Adds a space at the end of the layout and immediately set its ratio.

ratioRatio for the space

◆ get()

Widget::Ptr tgui::BoxLayout::get ( std::size_t  index)

Returns the widget at the given index in the layout.

Parameters
indexIndex of the widget in the layout
Returns
Widget of given index, or nullptr when index was too high

◆ getFixedSize() [1/2]

float tgui::BoxLayout::getFixedSize ( const Widget::Ptr widget)

Returns the size of a widget when it has a constant value.

Having a fixed size cancel the effect of the ratio. When 0 is returned then the size of the widget is variable and determined by the ratio.

Parameters
widgetPointer to the widget
Returns
Fixed size of the widget or 0 when size is variable

◆ getFixedSize() [2/2]

float tgui::BoxLayout::getFixedSize ( std::size_t  index)

Returns the size of a widget when it has a constant value.

Having a fixed size cancel the effect of the ratio. When 0 is returned then the size of the widget is variable and determined by the ratio.

Parameters
indexIndex of the widget in the layout
Returns
Fixed size of the widget or 0 when size is variable or index is too high

◆ getRatio() [1/2]

float tgui::BoxLayout::getRatio ( const Widget::Ptr widget)

Returns the ratio of a widget.

The ratio is the size that will have a widget relatively to others. By default, the ratio is equal to 1. So setting a ratio to 2 means that the widget will be 2 times larger than others.

Parameters
widgetPointer to the widget
Returns
Ratio given to the widget

◆ getRatio() [2/2]

float tgui::BoxLayout::getRatio ( std::size_t  index)

Returns the ratio of a widget.

The ratio is the size that will have a widget relatively to others. By default, the ratio is equal to 1. So setting a ratio to 2 means that the widget will be 2 times larger than others.

Parameters
indexIndex of the widget in the layout
Returns
Ratio given to the widget or 0 when when the index was too high

◆ insert()

bool tgui::BoxLayout::insert ( std::size_t  index,
const tgui::Widget::Ptr widget,
const sf::String &  widgetName = "" 
)

Insert a widget to the layout.

Parameters
widgetPointer to the widget you would like to add
indexIndex of the widget in the container
widgetNameAn identifier to access to the widget later

The widget will have ratio 1.

If the index is too high, the widget will simply be added at the end of the list.

Returns
False when the index was too high

◆ insertSpace()

bool tgui::BoxLayout::insertSpace ( std::size_t  index,
float  ratio = 1 
)

Insert a space to the layout and immediately set its ratio.

Parameters
indexIndex of the space in the container
ratioRatio for the space

If the index is too high, the space will simply be added at the end of the list.

Returns
False when the index was too high

◆ remove() [1/2]

bool tgui::BoxLayout::remove ( const tgui::Widget::Ptr widget)
overridevirtual

Removes a single widget that was added to the container.

Parameters
widgetPointer to the widget to remove
Returns
True when widget is removed, false when widget was not found

Reimplemented from tgui::Container.

◆ remove() [2/2]

bool tgui::BoxLayout::remove ( std::size_t  index)

Removes a single widget that was added to the container.

Parameters
indexIndex in the layout of the widget to remove
Returns
False when the index was too high

◆ setFixedSize() [1/2]

bool tgui::BoxLayout::setFixedSize ( const Widget::Ptr widget,
float  size 
)

Set the size of a widget to a constant value.

Setting a fixed size cancel the effect of the ratio. If you want to get a variable size again for a widget, set the fixed size to 0.

Parameters
widgetPointer to the widget
sizeNew fixed size of the widget
Returns
False when the widget was not found

◆ setFixedSize() [2/2]

bool tgui::BoxLayout::setFixedSize ( std::size_t  index,
float  size 
)

Set the size of a widget to a constant value.

Setting a fixed size cancel the effect of the ratio. If you want to get a variable size again for a widget, set the fixed size to 0.

Parameters
indexIndex of the widget in the layout
sizeNew fixed size of the widget
Returns
False when the index was too high

Parameters
fontThe new font.

When you don't call this function then the font from the parent widget will be used.

Reimplemented from tgui::Container.

◆ setRatio() [1/2]

bool tgui::BoxLayout::setRatio ( const Widget::Ptr widget,
float  ratio 
)

Change the ratio of a widget.

The ratio is the size that will have a widget relatively to others. By default, the ratio is equal to 1. So setting a ratio to 2 means that the widget will be 2 times larger than others.

Parameters
widgetPointer to the widget
ratioNew ratio to set to the widget
Returns
True when the ratio was changed, false when the widget was not found

◆ setRatio() [2/2]

bool tgui::BoxLayout::setRatio ( std::size_t  index,
float  ratio

Change the ratio of a widget. The ratio is the size that will have a widget relatively to others. By default, the ratio is equal to 1. So setting a ratio to 2 means that the widget will be 2 times larger than others.

Parameters
indexIndex of the widget in the layout
ratioNew ratio to set to the widget

If the index was too high then no change will be made

Returns
False when the index was too high

◆ setSize() [1/3]

const Layout height 
)
inline

Changes the size of the widget.

Parameters
widthWidth of the widget
heightHeight of the widget

Usage examples:

// Give the widget an exact size
widget->setSize(40, 30);
// Make the widget 50 pixels higher than some other widget
widget->setSize(otherWidget->getSize().x, otherWidget->getSize().y + 50);

virtual

Changes the size of the widget.

Parameters
sizeSize of the widget

Usage examples:

// Give the widget an exact size
widget->setSize({40, 30});
// Make the widget 50 pixels higher than some other widget
widget->setSize(otherWidget->getSize() + sf::Vector2f{0, 50});
// Make the widget 50 pixels higher than some other widget and automatically resize it when the other widget resizes
