Fingers
Elementary Infrastructure

Elementary is designed to be finger-friendly for touchscreens, and so in addition to scaling for display resolution, it can also scale based on finger "resolution" (or size). You can then customize the granularity of the areas meant to receive clicks on touchscreens.

Different profiles may have pre-set values for finger sizes.

Function Documentation

Evas_Coord elm_config_finger_size_get ( void  )

Get the configured "finger size"

Returns:
The finger size

This gets the globally configured finger size, in pixels

Since :
2.3.1
void elm_config_finger_size_set ( Evas_Coord  size)

Set the configured finger size

This sets the globally configured finger size in pixels

Parameters:
sizeThe finger size
Since :
2.3.1
void elm_coords_finger_size_adjust ( int  times_w,
Evas_Coord *  w,
int  times_h,
Evas_Coord *  h 
)

Adjust size of an element for finger usage.

Parameters:
times_wHow many fingers should fit horizontally
wPointer to the width size to adjust
times_hHow many fingers should fit vertically
hPointer to the height size to adjust

This takes width and height sizes (in pixels) as input and a size multiple (which is how many fingers you want to place within the area, being "finger" the size set by elm_config_finger_size_set()), and adjusts the size to be large enough to accommodate the resulting size -- if it doesn't already accommodate it. On return the w and h sizes pointed to by these parameters will be modified, on those conditions.

Note:
This is kind of low level Elementary call, most useful on size evaluation times for widgets. An external user wouldn't be calling, most of the time.
Since :
2.3.1
EINA_DEPRECATED void elm_finger_size_all_set ( Evas_Coord  size)

Set the configured finger size for all applications on the display

This sets the globally configured finger size in pixels for all applications on the display

Parameters:
sizeThe finger size
Deprecated:
Use elm_config_finger_size_set() and elm_config_all_flush()
