◆ setMaximum()

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

Sets a maximum value.

Parameters

maximum The 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::Slider::setMinimum ( float minimum )

◆ setSize() [1/2]

void tgui::Slider::setSize ( const Layout2d & size )

overridevirtual

Changes the size of the slider.

Parameters

size	The new size of the slider

Note that the Orientation propery is changed by this function based on the given width and height, unless the setOrientation function was previously called to explicitly select the orientation.

Reimplemented from tgui::Widget.

◆ setSize() [2/2]

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

inline

Changes the size of the widget.

Parameters

width	Width of the widget
height	Height of the widget

Warning: This setSize overload must never be used from internal TGUI code or by custom widget implementations

◆ setStep()

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

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

Parameters

step	The 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.

◆ setValue()

void tgui::Slider::setValue ( float value )

Changes the current value.

Parameters

value The new value

The value can't be smaller than the minimum or bigger than the maximum. The default value is 0.

◆ setVerticalScroll()

void tgui::Slider::setVerticalScroll ( bool vertical )

Changes whether the slider lies horizontally or vertically.

Parameters

vertical Should the slider lie vertically?

This function will swap the width and height of the slider if it didn't lie in the wanted direction.
