|
|
* 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.
|
|
*
|
|
* @ref general_functions_example_page "This" example contemplates
|
|
* some of these functions.

/**
|
|
* Adjust size of an element for finger usage.
|
|
*
|
|
* @param times_w How many fingers should fit horizontally
|
|
* @param w Pointer to the width size to adjust
|
|
* @param times_h How many fingers should fit vertically
|
|
* @param h Pointer 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 @p w and @p 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.
