finite_overlay_init

The finite_overlay_init function creates a new layer-shell window with a given FiniteShell.

void finite_overlay_init(FiniteShell *shell, int layer, char *name)

Parameters

Type	Description
`FiniteShell *shell`	The FiniteShell to create a window for.
`int layer`	The int value of the `zwlr_layer_shell_v1_layer` to draw on. Usually 3.
`char *name`	The name of the layer-shell window.

Code Example

finite_log_init(stdout, LOG_LEVEL_DEBUG, true);
shell = finite_shell_init("wayland-0"); // get the device

finite_overlay_init(shell, 3, "overlay");
finite_overlay_set_size_and_position(shell, 200, 100, ZWLR_LAYER_SURFACE_V1_ANCHOR_BOTTOM | ZWLR_LAYER_SURFACE_V1_ANCHOR_RIGHT);


// try and draw
finite_shm_alloc(shell, false);

FiniteColorGroup test = { 0.827, 0.247, 0.286 };
finite_draw_rect(shell, 0,0, 200, 100, &test, NULL);

finite_draw_finish(shell, 200, 100, shell->stride, false);
int state = wl_display_dispatch(shell->display);

while (state != -1) {}
FINITE_LOG("Done.");
wl_surface_destroy(shell->isle_surface);
finite_draw_cleanup(shell);

Standard Usage

When creating an overlay Developers should not ateempt to set the shared memory buffer (shm) until AFTER calling finite_overlay_set_size_and_position
