Detailed Description

Abstract class for box layout containers.

Member Function Documentation

◆ add()

void tgui::BoxLayout::add ( const Widget::Ptr & widget,
const 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
Warning
Widgets should be named as if they are C++ variables, i.e. names must not include any whitespace, or most symbols (e.g.: +, -, *, /, ., &), and should not start with a number. If you do not follow these rules, layout expressions may give unexpected results. Alphanumeric characters and underscores are safe to use, and widgets are permitted to have no name.

Reimplemented from tgui::Container.

Reimplemented in tgui::BoxLayoutRatios.

◆ get() [1/2]

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

Returns a pointer to a widget that was added earlier.

Parameters
widgetNameThe name that was given to the widget when it was added to the 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 added widget
Warning
This function will return nullptr when an unknown widget name was passed

◆ get() [2/2]

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

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 if index was too high

◆ getRenderer()

TGUI_NODISCARD BoxLayoutRenderer * tgui::BoxLayout::getRenderer ( )
overridevirtual

Returns the renderer, which gives access to functions that determine how the widget is displayed.

Returns
Temporary pointer to the renderer
Warning
After calling this function, the widget has its own copy of the renderer and it will no longer be shared.

Reimplemented from tgui::Widget.

◆ getSharedRenderer() [1/2]

TGUI_NODISCARD const BoxLayoutRenderer * tgui::BoxLayout::getSharedRenderer ( ) const
overridevirtual

Reimplemented from tgui::Widget.

◆ getSharedRenderer() [2/2]

TGUI_NODISCARD BoxLayoutRenderer * tgui::BoxLayout::getSharedRenderer ( )
overridevirtual

Returns the renderer, which gives access to functions that determine how the widget is displayed.

Returns
Temporary pointer to the renderer that may be shared with other widgets using the same renderer

Reimplemented from tgui::Widget.

◆ insert()

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

Inserts 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

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

Warning
Widgets should be named as if they are C++ variables, i.e. names must not include any whitespace, or most symbols (e.g.: +, -, *, /, ., &), and should not start with a number. If you do not follow these rules, layout expressions may give unexpected results. Alphanumeric characters and underscores are safe to use, and widgets are permitted to have no name.

Reimplemented in tgui::BoxLayoutRatios.

◆ remove() [1/2]

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

Removes a single widget that was added to the container.

Parameters
widgetPointer to the widget to remove

Reimplemented from tgui::Container.

Reimplemented in tgui::BoxLayoutRatios.

◆ remove() [2/2]

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

Removes a single widget that was added to the container.

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

Reimplemented in tgui::BoxLayoutRatios.

◆ rendererChanged()

void tgui::BoxLayout::rendererChanged ( const String & property)
overrideprotectedvirtual

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

Parameters
propertyName of the property that was changed

Reimplemented from tgui::Widget.
