Definitions for libvirtualhid Unix input handling.

Function Documentation

get_capabilities()

platform_caps::caps_t platf::get_capabilities

(

)

Get the supported platform capabilities to advertise to the client.

Returns the supported platform capabilities to advertise to the client.

Returns

Capability flags.

get_mouse_loc()

std::optional< util::point_t > platf::get_mouse_loc

(

input_t &

input

)

Get the current mouse position for platform input tests.

Parameters

input

The input_t instance to use.

Returns

Screen coordinates of the mouse, or std::nullopt when the platform cannot observe the cursor.

Note

This helper exists only so tests can observe virtual mouse movement. Production input paths should submit mouse events through move_mouse() or abs_mouse() instead of reading the host cursor location.

Examples

if (auto location = get_mouse_loc(input)) {
  auto [x, y] = *location;
}

supported_gamepads()

std::vector< supported_gamepad_t > & platf::supported_gamepads

(

input_t *

input

)

Gets the supported gamepads for this platform backend.

This may be called prior to platf::input()!

Parameters

input

Pointer to the platform's input_t or nullptr.

Returns

Vector of gamepad options and status.
