finite_overlay_set_margin

The finite_overlay_set_margin function sets margin of the active layer-shell window.

void finite_overlay_set_margin(FiniteShell *shell, int top, int bottom, int left, int right);

Parameters

Type	Description
`FiniteShell *shell`	The FiniteShell to create a window for.
`int top`	The top margin
`int bottom`	The bottom margin
`int left`	The left margin
`int right`	The right margin

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);
finite_overlay_set_margin(shell, 0 , 50, 0, 50);

// 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.");
finite_draw_cleanup(shell);

Standard Usage

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

This function should be called AFTER finite_overlay_set_size_and_position. Margins set for anchors the shell does not control will have no effect.
