Removing spacing between widgets?
Honestly this is such a minor thing that I hesitated to create an issue. I'm trying to create a row of buttons without any spacing between them, but tiny gaps still appear depending on the window size. I might just be doing something wrong or maybe this is a known limitation.
MRE and screenshot below (using the SDL3 renderer):
static void buttons_no_spacing(struct nk_context *ctx) {
struct nk_style_button button_style;
nk_flags flags = NK_WINDOW_TITLE | NK_WINDOW_BORDER | NK_WINDOW_MOVABLE | NK_WINDOW_SCALABLE;
if (nk_begin(ctx, "Buttons No Spacing", nk_rect(50, 50, 333, 333), flags)) {
nk_style_push_vec2(ctx, &ctx->style.window.spacing, nk_vec2(0, 0));
button_style = ctx->style.button;
button_style.rounding = 0.0f;
button_style.border = 0.0f;
button_style.normal = nk_style_item_color(nk_rgb(0, 255, 255));
button_style.hover = nk_style_item_color(nk_rgb(255, 255, 0));
button_style.active = nk_style_item_color(nk_rgb(0, 255, 0));
nk_layout_row_dynamic(ctx, 0, 4);
nk_button_label_styled(ctx, &button_style, "Header1");
nk_button_label_styled(ctx, &button_style, "Header2");
nk_button_label_styled(ctx, &button_style, "Header3");
nk_button_label_styled(ctx, &button_style, "Header4");
nk_style_pop_vec2(ctx);
}
nk_end(ctx);
}Activity

TomJGooding11d agoThanks @RobLoach - I was worried that I might just be doing something wrong, so I'm glad you didn't spot anything obvious at least.
I haven't dived into the code yet, but presuming something like:
window_width = 333
column_count = 4
// Assuming window spacing set to zero
widget_widthf = window_width / column_count // 83.25
widget_width = floor(widget_widthf)
leftover = window_width - (widget_width * column count) // 1My guess is these remaining gaps is where nk_layout_row_dynamic tries to redistribute the leftover space?
TomJGooding2d agoBased on the example above:
panel_space = 311.0
columns = 4
w = panel_space / columns
item_offsets = [w * i for i in range(columns)]
# [0.0, 77.75, 155.5, 233.25]
item_widths = [w + off - int(off+0.5) for off in item_offsets]
# [77.75, 77.5, 77.25, 78.0]Presumably somewhere (nk_widget?) these bounds are cast to ints:
xs = [int(x) for x in item_offsets]
# [0, 77, 155, 233]
ws = [int(w) for w in item_widths]
# [77, 77, 77, 78]
gaps = [xs[i+1] - (xs[i] + ws[i]) for i in range(len(xs)-1)]
# [0, 1, 1]
I think there was some discussion around margin/padding at some point. Not sure where that landed. I agree the spacing in general should get fixed, because there is confusion.
