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.

◆ copy()

static RangeSlider::Ptr tgui::RangeSlider::copy ( RangeSlider::ConstPtr  slider)
static

Makes a copy of another slider.

Parameters
sliderThe other slider
Returns
The new slider

◆ create()

static RangeSlider::Ptr tgui::RangeSlider::create ( float  minimum = 0,
float  maximum = 10 
)
static

Creates a new slider widget.

Parameters
minimumThe minimum value of the slider
maximumThe maximum value of the slider
Returns
The new slider

◆ draw()

void tgui::RangeSlider::draw ( BackendRenderTargetBase target,
RenderStates  states 
) const

Draw the widget to a render target.

Parameters
targetRender target to draw to
statesCurrent render states

Implements tgui::Widget.

◆ getFullSize()

Vector2f tgui::RangeSlider::getFullSize ( ) const
overridevirtual

Returns the full size of the slider.

Returns
Full size of the slider

Reimplemented from tgui::Widget.

◆ getMaximum()

The default minimum value is 0.

◆ getRenderer()

RangeSliderRenderer * tgui::RangeSlider::getRenderer ( )

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

Returns
Temporary pointer to the renderer

float tgui::RangeSlider::getSelectionEnd ( ) const

Returns the current value where the selection ends.

Returns
The current selection end

◆ getSelectionStart()

float tgui::RangeSlider::getSelectionStart ( ) const

Returns the current value where the selection starts.

Returns
The current selection start

◆ getSharedRenderer()

RangeSliderRenderer * tgui::RangeSlider::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

◆ getSignal()

Signal & tgui::RangeSlider::getSignal ( String  signalName)
overrideprotectedvirtual

Retrieves a signal based on its name.

Parameters
signalNameName of the signal
Returns
Signal that corresponds to the name
Exceptions
Exceptionwhen the name does not match any signal

Reimplemented from tgui::Widget.

◆ getStep()

float tgui::RangeSlider::getStep ( ) const

Returns the number of positions the thumb advances with each move.

Returns
The current step size
See also
setStep

◆ getWidgetOffset()

Vector2f tgui::RangeSlider::getWidgetOffset ( ) const
overridevirtual

Reimplemented from tgui::Widget.

◆ setMaximum()

void tgui::RangeSlider::setMaximum ( float  maximum)

Sets a maximum value.

Parameters
maximumThe new maximum value

When the value is too big then it will be changed to this maximum. When the minimum value is higher than the new maximum then it will be changed to this new maximum value. The default maximum value is 10.

◆ setMinimum()

void tgui::RangeSlider::setMinimum ( float  minimum)

Sets a minimum value.

Parameters
minimumThe new minimum value

When the value is too small then it will be changed to this minimum. When the maximum value is lower than the new minimum then it will be changed to this new minimum value. The default minimum value is 0.

◆ setSelectionEnd()

void tgui::RangeSlider::setSelectionEnd ( float  value)

Changes the value where the selection ends.

Parameters
valueThe new selection end

The value can't be smaller than the minimum or bigger than the maximum. When smaller than SelectionStart, SelectionStart will be set to the value as well.

◆ setSelectionStart()

void tgui::RangeSlider::setSelectionStart ( float  value)

Changes the value where the selection starts.

Parameters
valueThe new selection start

The value can't be smaller than the minimum or bigger than the maximum. When larger than SelectionEnd, SelectionEnd will be set to the value as well.

◆ 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});

Reimplemented from tgui::Widget.

◆ setSize() [2/3]

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

Changes the size of the slider.

Parameters
sizeThe new size of the slider

Reimplemented from tgui::Widget.

◆ setSize() [3/3]

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

Changes the size of the widget.

Parameters
widthWidth of the widget
heightHeight of the widget
Warning
This setSize overload must never be used from internal TGUI code or by custom widget implementations

◆ setStep()

void tgui::RangeSlider::setStep ( float  step)

Changes the number of positions the thumb advances with each move.

Parameters
stepThe new step size
Precondition
The step size must be a positive value or 0. The default step size is 1, which means the slider will only use integer values between minimum and maximum. When set to 0, the slider will be able to use any floating point value between minimum and maximum. If minimum is 20, maximum is 50 and step size is set to 10, possible slider values would be 20, 30, 40 and 50.
