Function Documentation

_wlmim_pointer_apply()

void _wlmim_pointer_apply	(	wlmim_pointer_t *	p,
		const struct wlmim_pointer_param *	param_ptr
	)

Applies the touchpad configuration to the pointer input device.

A no-op if the device is not a touchpad, ie. has zero 'tap fingers'.

Parameters

p
param_ptr

_wlmim_pointer_test_parse()

void _wlmim_pointer_test_parse ( bs_test_t *  test_ptr )

static

Tests parsing the dict.

wlmim_pointer_create()

wlmim_pointer_t * wlmim_pointer_create	(	struct wlr_input_device *	wlr_input_device_ptr,
		const struct wlmim_pointer_param *	param_ptr
	)

Creates a pointer, and configures it as specified.

Parameters

wlr_input_device_ptr
param_ptr

Returns

A pointer handle or NULL on error.

wlmim_pointer_destroy()

void wlmim_pointer_destroy

(

wlmim_pointer_t *

pointer_ptr

)

Destroys the pointer.

Parameters

pointer_ptr

wlmim_pointer_enabled()

bool wlmim_pointer_enabled

(

wlmim_pointer_t *

pointer_ptr

)

Returns

wlmim_pointer_t::enabled.

wlmim_pointer_parse_config()

bool wlmim_pointer_parse_config	(	bspl_dict_t *	config_dict_ptr,
		struct wlmim_pointer_param *	param_ptr
	)

Parses the pointer-specific parts of the config dict.

Parameters

config_dict_ptr
param_ptr

Returns

true on success
