lv_uefi_indev.h

Functions

lv_indev_t *lv_uefi_simple_pointer_indev_create(lv_point_t *display_res)

Create an indev object.

Parameters:: display_res – The resolution of the display in pixels, needed to scale the input. If NULL the resolution of the current default display will be used.
Returns:: The created LVGL indev object.

bool lv_uefi_simple_pointer_indev_add_handle(lv_indev_t *indev, EFI_HANDLE handle)

Add an EFI_SIMPLE_POINTER_PROTOCOL interface to the indev.

Parameters:

indev – Indev that was created with lv_uefi_simple_pointer_indev_create.
handle – The handle on which an instance of the EFI_SIMPLE_POINTER_PROTOCOL protocol is installed.

Returns:

True if the interface was added.

void lv_uefi_simple_pointer_indev_add_all(lv_indev_t *indev)

Add all available EFI_SIMPLE_POINTER_PROTOCOL interfaces to the indev.

Parameters:: indev – Indev that was created with lv_uefi_simple_pointer_indev_create.

lv_indev_t *lv_uefi_absolute_pointer_indev_create(lv_point_t *display_res)

Create a LVGL indev object.

Parameters:: display_res – The resolution of the display in pixels, needed to scale the input.
Returns:: The created LVGL indev object.

bool lv_uefi_absolute_pointer_indev_add_handle(lv_indev_t *indev, EFI_HANDLE handle)

Add an EFI_ABSOLUTE_POINTER_PROTOCOL interface to the indev.

Parameters:

indev – Indev that was created with lv_uefi_absolute_pointer_indev_create.
handle – The handle on which an instance of the EFI_ABSOLUTE_POINTER_PROTOCOL protocol is installed.

Returns:

True if the interface was added.

void lv_uefi_absolute_pointer_indev_add_all(lv_indev_t *indev)

Add all available EFI_ABSOLUTE_POINTER_PROTOCOL interfaces to the indev.

Parameters:: indev – Indev that was created with lv_uefi_absolute_pointer_indev_create.

lv_indev_t *lv_uefi_simple_text_input_indev_create(void)

Create an indev object.

bool lv_uefi_simple_text_input_indev_add_handle(lv_indev_t *indev, EFI_HANDLE handle)

Add an EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL interface to the indev.

Parameters:

indev – Indev that was created with lv_uefi_simple_text_input_indev_create.
handle – The handle on which an instance of the EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL protocol is installed.

Returns:

True if the interface was added.

void lv_uefi_simple_text_input_indev_add_all(lv_indev_t *indev)

Add all available EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL interfaces to the indev.

Parameters:: indev – Indev that was created with lv_uefi_simple_text_input_indev_create.
