Detailed Description

A control for selecting a numeric value by sliding along a scale.

An implementation of a slider where a user can select different values by sliding between a start value and an end value of a scale. If the selected value is changed an action event will be sent to all action listeners of the slider.

Definition at line 27 of file slider.hpp.

Member Function Documentation

◆ draw()

void fcn::Slider::draw ( Graphics * graphics )

overridevirtual

Draws the widget.

The call to draw is initiated by the widget's parent. The graphics object is set up so that all drawing is relative to the widget, i.e coordinate (0,0) is the top left corner of the widget. It is not possible to draw outside of a widget's dimension. If a widget has children, the parent's draw function will always be called before the children's draw functions are called.

NOTE: A widget with children won't draw its children unless the children area given by Widget::getChildrenArea returns a none empty rectangle inside the widgets dimension. The children area is considered relative to the widget's position.

Parameters

Graphics & Rendering A graphics object to draw with.

See also: getChildrenArea, drawOutline, drawBorder

Implements fcn::Widget.
