nk_tooltip out of windows bounds and unreadable

[Farsthary]

Hi
When I try to make tooltips on a right toolbar, I get them displayed out of the actual windows bound. Is is possible to have them flipped? or a parameter to have it flipped?

Well, I kind of hacked the code to achieve what I wanted

`NK_API int
nk_tooltip_begin_flipped(struct nk_context* ctx, float width)
{
int x, y, w, h;
struct nk_window* win;
const struct nk_input* in;
struct nk_rect bounds;
int ret;

NK_ASSERT(ctx);
NK_ASSERT(ctx->current);
NK_ASSERT(ctx->current->layout);
if (!ctx || !ctx->current || !ctx->current->layout)
	return 0;

/* make sure that no nonblocking popup is currently active */
win = ctx->current;
in = &ctx->input;
if (win->popup.win && (win->popup.type & NK_PANEL_SET_NONBLOCK))
	return 0;

w = nk_iceilf(width);
h = nk_iceilf(nk_null_rect.h);
x = nk_ifloorf(in->mouse.pos.x + 1) - (int)win->layout->clip.x - w;
y = nk_ifloorf(in->mouse.pos.y + 1) - (int)win->layout->clip.y;

bounds.x = (float)x;
bounds.y = (float)y;
bounds.w = (float)w;
bounds.h = (float)h;

ret = nk_popup_begin(ctx, NK_POPUP_DYNAMIC,
	"__##Tooltip##__", NK_WINDOW_NO_SCROLLBAR | NK_WINDOW_BORDER, bounds);
if (ret) win->layout->flags &= ~(nk_flags)NK_WINDOW_ROM;
win->popup.type = NK_PANEL_TOOLTIP;
ctx->current->layout->type = NK_PANEL_TOOLTIP;
return ret;

}

NK_API void
nk_tooltip_flipped(struct nk_context* ctx, const char* text)
{
const struct nk_style* style;
struct nk_vec2 padding;

int text_len;
float text_width;
float text_height;

NK_ASSERT(ctx);
NK_ASSERT(ctx->current);
NK_ASSERT(ctx->current->layout);
NK_ASSERT(text);
if (!ctx || !ctx->current || !ctx->current->layout || !text)
	return;

/* fetch configuration data */
style = &ctx->style;
padding = style->window.padding;

/* calculate size of the text and tooltip */
text_len = nk_strlen(text);
text_width = style->font->width(style->font->userdata,
	style->font->height, text, text_len);
text_width += (4 * padding.x);
text_height = (style->font->height + 2 * padding.y);

/* execute tooltip and fill with text */
if (nk_tooltip_begin_flipped(ctx, (float)text_width)) {
	nk_layout_row_dynamic(ctx, (float)text_height, 1);
	nk_text(ctx, text, text_len, NK_TEXT_LEFT);
	nk_tooltip_end(ctx);
}

}`
Though It may be simpler to just add a bool parameter to nk_tooltip directly

You're right, there is no way of "flipping" it. But this could be made fully automagically internally decided (without exposing any flag or API call). Feel free to make a pull request 😉.

Thanks, will do it soon :)
