AG_SLIDER(3) Library Functions Manual AG_SLIDER(3) NAME AG_Slider -- agar slider widget SYNOPSIS #include <agar/core.h> #include <agar/gui.h> DESCRIPTION The AG_Slider widget allows the user to control an integer or floating- point value within a specified range. It can be thought as a graphical alternative to AG_Numerical(3). INHERITANCE HIERARCHY AG_Object(3) -> AG_Widget(3) -> AG_Slider. INTERFACE AG_Slider * AG_SliderNew(AG_Widget *parent, enum ag_slider_type type, Uint flags) void AG_SliderSetControlSize(AG_Slider *slider, int pixels) The AG_SliderNew() function allocates, initializes, and attaches a new AG_Slider widget. type defines the orientation of the slider: enum ag_slider_type { AG_SLIDER_HORIZ, AG_SLIDER_VERT }; Acceptable flags include: AG_SLIDER_EXCL Advise that no external changes to the value, min and max bindings are expected. By default, the binding values are periodically checked and the slider is redrawn if a change is detected. Note that this setting only influences redraw -- external changes to the binding values are handled safely re- gardless. AG_SLIDER_HFILL Expand horizontally in parent container. AG_SLIDER_VFILL Expand vertically in parent container. AG_SLIDER_EXPAND Shorthand for AG_SLIDER_HFILL | AG_SLIDER_VFILL. The AG_SliderSetControlSize() function specifies a preferred size for the slider control, in pixels. BINDINGS The AG_Slider widget provides the following bindings: float *{value,min,max,inc} Single precision number double *{value,min,max,inc} Double precision number int *{value,min,max,inc} Natural integer Uint *{value,min,max,inc} Unsigned integer [SU]int8 *{value,min,max,inc} Fixed 8-bit integer [SU]int16 *{value,min,max,inc} Fixed 16-bit integer [SU]int32 *{value,min,max,inc} Fixed 32-bit integer [SU]int64 *{value,min,max,inc} Fixed 64-bit integer The slider is positioned to represent value inside of the range defined by min and max. The optional inc binding specifies the increment effected by the but- tons, or keyboard. If not specified, it defaults to 0.1 (for floating- point values), or 1 (for integer values). Note that the min, max and inc bindings must share the same type as value. The 64-bit types are only available if AG_HAVE_64BIT is set. EVENTS The AG_Slider widget generates the following events: slider-changed(void) The slider's value has changed. slider-drag-begin(void) User is starting to drag the slider. slider-drag-end(void) User is done dragging the slider.
