Function Documentation

◆ ui_slider_event()

bool ui_slider_event	(	ui_slider_t *	s,
		const touch_event_t *	evt )

Returns true when the value changed as a result of this event.

◆ ui_slider_painted_rect()

gfx_rect_t ui_slider_painted_rect ( const ui_slider_t * s )

Every pixel ui_slider_render may touch, the thumb's overhang and its shadow included. A caller that repaints the slider without repainting everything around it clears this and not the track, or the thumb's old positions stay on the screen.

◆ ui_slider_release()

void ui_slider_release ( ui_slider_t * s )

Abandon a drag that will get no release, on leaving a screen.

◆ ui_slider_set_presets()

void ui_slider_set_presets	(	ui_slider_t *	s,
		const float *	values,
		const char const	labels,
		int	count,
		gfx_rect_t	row )

Sets the presets, laid out in a row inside row with 4px gaps.

Parameters

s	the slider
values	the presets' values
labels	their labels
count	how many
row	the row they take

◆ ui_slider_set_tap_to_set()

void ui_slider_set_tap_to_set	(	ui_slider_t *	s,
		bool	on )

Let a press set the value under it. Off by default; a throttle must not take a value from one contact.

◆ ui_slider_set_ticks()

void ui_slider_set_ticks	(	ui_slider_t *	s,
		int	n )

Draw n scale divisions across the track. 0 turns them off.
