Member Function Documentation

◆ add()

virtual void tgui::Container::add ( const Widget::Ptr widgetPtr,
const sf::String &  widgetName = "" 
)
virtual

Adds a widget to the container.

Parameters
widgetPtrPointer to the widget you would like to add
widgetNameIf you want to access the widget later then you must do this with this name
Warning
The widget name should not contain whitespace

Reimplemented in tgui::ScrollablePanel, tgui::BoxLayout, and tgui::BoxLayoutRatios.

◆ focusNextWidget()

void tgui::Container::focusNextWidget ( )

Focuses the next widget.

The currently focused widget will be unfocused, even if it was the only widget. When no widget was focused, the first widget in the container will be focused.

◆ focusPreviousWidget()

void tgui::Container::focusPreviousWidget ( )

Focuses the previous widget.

The currently focused widget will be unfocused, even if it was the only widget. When no widget was focused, the last widget in the container will be focused.

◆ focusWidget()

void tgui::Container::focusWidget ( const Widget::Ptr widget)

Focuses a widget.

The previously focused widget will be unfocused.

Parameters
widgetThe widget that has to be focused

◆ get() [1/2]

Widget::Ptr tgui::Container::get ( const sf::String &  widgetName) const

Returns a pointer to an earlier created widget.

Parameters
widgetNameThe name that was given to the widget when it was added to the container
recursiveShould the function also search for widgets inside containers that are inside this container?

The container will first search for widgets that are direct children of it, but when none of the child widgets match the given name, a recursive search will be performed.

Returns
Pointer to the earlier created widget
Warning
This function will return nullptr when an unknown widget name was passed

◆ get() [2/2]

template<class T >
T::Ptr tgui::Container::get ( const sf::String &  widgetName) const
inline

Returns a pointer to an earlier created widget.

Parameters
widgetNameThe name that was given to the widget when it was added to the container
recursiveShould the function also search for widgets inside containers that are inside this container?
Returns
Pointer to the earlier created widget. The pointer will already be casted to the desired type

The container will first search for widgets that are direct children of it, but when none of the child widgets match the given name, a recursive search will be performed.

Warning
This function will return nullptr when an unknown widget name was passed

◆ getChildWidgetsOffset()

Loads the child widgets from a string stream.

Parameters
streamstringstream that contains the widget file

Places a widget behind all other widgets.

Parameters
widgetThe widget that should be moved to the back

virtual

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

◆ rendererChanged()

void tgui::Container::rendererChanged ( const std::string &  property)
overrideprotectedvirtual

Function called when one of the properties of the renderer is changed.
