Constructor & Destructor Documentation

◆ Group()

tgui::Group::Group ( const Layout2d size = {"100%", "100%"})

Default constructor.

Parameters
sizeSize of the group

Member Function Documentation

◆ clone()

Widget::Ptr tgui::Group::clone ( ) const
inlineoverrideprotectedvirtual

Makes a copy of the widget if you don't know its exact type.

This function should only be used when you don't know the type of the widget. If you know what kind of widget you are copying, you should use the copy function.

Returns
Copy of the widget

Implements tgui::Widget.

Reimplemented in tgui::HorizontalLayout, tgui::HorizontalWrap, tgui::Panel, tgui::RadioButtonGroup, tgui::ScrollablePanel, and tgui::VerticalLayout.

◆ copy()

static Group::Ptr tgui::Group::copy ( Group::ConstPtr  group)
static

Makes a copy of another group.

Parameters
groupThe other group
Returns
The new group

◆ create()

static Group::Ptr tgui::Group::create ( const Layout2d size = {"100%", "100%"})
static

Creates a new group.

Parameters
sizeSize of the group
Returns
The new group

◆ draw()

void tgui::Group::draw ( sf::RenderTarget &  target,
sf::RenderStates  states 
) const
overridevirtual

Draw the child widgets to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Implements tgui::Widget.

Reimplemented in tgui::Panel, tgui::RadioButtonGroup, and tgui::ScrollablePanel.

◆ getChildWidgetsOffset()

Vector2f tgui::Group::getChildWidgetsOffset ( ) const
overridevirtual

Returns the distance between the position of the container and a widget that would be drawn inside this container on relative position (0,0)

◆ getRenderer()

GroupRenderer * tgui::Group::getRenderer ( )

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.

◆ getSharedRenderer()

GroupRenderer * tgui::Group::getSharedRenderer ( )

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

◆ mouseOnWidget()

bool tgui::Group::mouseOnWidget ( Vector2f  pos) const
overridevirtual

Returns whether the mouse position (which is relative to the parent widget) lies on top of the widget.

Returns
Is the mouse on top of the widget?

Implements tgui::Widget.

Reimplemented in tgui::Panel.

◆ rendererChanged()

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

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

propertyLowercase name of the property that was changed

Reimplemented from tgui::Container.

Reimplemented in tgui::Panel, and tgui::ScrollablePanel.

◆ setSize() [1/3]

virtual void tgui::Widget::setSize ( const Layout2d size)
virtual

Changes the size of the widget.

Parameters
sizeSize of the widget

Usage examples:

// Give the widget an exact size
widget->setSize({40, 30});
// Give the widget a size relative to the size of its parent
widget->setSize({"20%", "5%"});
// Make the widget 50 pixels higher than some other widget and automatically resize it when the other widget resizes
widget->setSize({200, tgui::bindHeight(otherWidget) + 50});
TGUI_API Layout bindHeight(std::shared_ptr< Widget > widget)
Bind to the height of the widget.

Reimplemented from tgui::Container.

◆ setSize() [2/3]

void tgui::Group::setSize ( const Layout2d size)
overridevirtual

Changes the size of the group.

Parameters
sizeThe new size of the group

void tgui::Widget::setSize ( Layout  width,
Layout  height 
)
inline

Changes the size of the widget.

Parameters
widthWidth of the widget
heightHeight of the widget
