Member Function Documentation

◆ clone()

virtual Widget::Ptr tgui::Button::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

Reimplemented from tgui::ClickableWidget.

◆ copy()

static Button::Ptr tgui::Button::copy ( Button::ConstPtr  button)
static

Makes a copy of another button.

Parameters
buttonThe other button
Returns
The new button

◆ create()

static Button::Ptr tgui::Button::create ( sf::String  text = "")
static

Creates a new button widget.

Parameters
textThe text to display on the button
Returns
The new button

◆ getFullSize()

virtual sf::Vector2f tgui::Button::getFullSize ( ) const
overridevirtual

Returns the full size of the button.

The size returned by this function includes the borders.

Returns
Full size of the button

Reimplemented from tgui::Transformable.

◆ getRenderer()

std::shared_ptr< ButtonRenderer > tgui::Button::getRenderer ( ) const
inline

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

Returns
Reference to the renderer

◆ getText()

const sf::String & tgui::Button::getText ( ) const
inline

Returns the caption of the button.

Returns
Text that is drawn on top of the button.

◆ getTextSize()

unsigned int tgui::Button::getTextSize ( ) const
inline

Returns the character size of the text.

Returns
The current text size.

◆ getWidgetOffset()

virtual sf::Vector2f tgui::Button::getWidgetOffset ( ) const
overridevirtual

Returns the distance between the position where the widget is drawn and where the widget is placed.

This is basically the width and height of the optional borders drawn around widgets.

Returns
Offset of the widget

Reimplemented from tgui::Widget.

◆ reload()

virtual void tgui::Button::reload ( const std::string &  primary = "",
const std::string &  secondary = "",
bool  force = false 
)
overrideprotectedvirtual

Reload the widget.

Parameters
primaryPrimary parameter for the loader
secondarySecondary parameter for the loader
forceTry to only change the looks of the widget and not alter the widget itself when false
Exceptions
Exceptionwhen the connected theme could not create the widget

When primary is an empty string the built-in white theme will be used.

Reimplemented from tgui::Widget.

◆ setFont()

virtual void tgui::Button::setFont ( const Font font)
overridevirtual

Changes the font of the text in the widget.

Parameters
fontThe new font.

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

Reimplemented from tgui::Widget.

◆ setOpacity()

virtual void tgui::Button::setOpacity ( float  opacity)
overridevirtual

Changes the opacity of the widget.

Parameters
opacityThe opacity of the widget. 0 means completely transparent, while 1 (default) means fully opaque.

Reimplemented from tgui::Widget.

◆ setPosition() [1/3]

void tgui::Transformable::setPosition ( const Layout x,
const Layout y 
)
inline

set the position of the widget

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable widget is (0, 0).

Parameters
xNew x coordinate
yNew y coordinate
See also
move, getPosition

Usage examples:

// Place the widget on an exact position
widget->setPosition(40, 30);
// Place the widget 50 pixels below another widget
widget->setPosition(otherWidget->getPosition().x, otherWidget->getPosition().y + otherWidget->getSize().y + 50);
// Place the widget 50 pixels below another widget and automatically move it when the other widget moves
widget->setPosition(tgui::bindLeft(otherWidget), tgui::bindBottom(otherWidget) + 50);
TGUI_API Layout bindBottom(std::shared_ptr< Widget > widget)
Bind to the bottom of the widget.
TGUI_API Layout bindLeft(std::shared_ptr< Widget > widget)
Bind to the x position of the widget.

◆ setPosition() [2/3]

virtual void tgui::Transformable::setPosition ( const Layout2d position)
virtual

This function completely overwrites the previous position. See the move function to apply an offset based on the previous position instead. The default position of a transformable widget is (0, 0).

Parameters
positionNew position
See also
move, getPosition

Usage examples:

// Place the widget on an exact position
widget->setPosition({40, 30});

widget->setPosition(otherWidget->getPosition() + sf::Vector2f{0, otherWidget->getSize().y + 50});
// Place the widget 50 pixels below another widget and automatically move it when the other widget moves
widget->setPosition({tgui::bindLeft(otherWidget), tgui::bindBottom(otherWidget) + 50});

Reimplemented from tgui::Widget.

◆ setPosition() [3/3]

virtual void tgui::Button::setPosition ( const Layout2d position)
overridevirtual

// 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
