Moving mouse out of Window when still holding scrollbar is treated as unactive

[SAOMDVN]

I have a simple Group on a Window widget. This Group has many elements which spawns a scrollbar. If I hold onto the scrollbar and move my mouse outside of the current window nk_item_is_any_active will return false even though I haven't let go of the scrollbar. The expected behaviour is the Group widget is still being active/focused.

I'm currently using the raylib runtime at https://github.com/RobLoach/raylib-nuklear

Thanks! Could possibly be an issue with the raylib implementation. Mind chatting there?

Ah, I'm not sure this is implementation specific. Do you have any sample code to test this? Does it work in the Overview example?

You can test with this:

int main() {
    InitWindow(640, 480, "raylib-nuklear example");

    // Create the Nuklear Context
    int fontSize = 10;
    const char *activeText[2] = {"Inactive", "Active"};
    struct nk_context *ctx = InitNuklear(fontSize);

    while (!WindowShouldClose()) {
        // Update the Nuklear context, along with input
        UpdateNuklear(ctx);

        // Nuklear GUI Code
        // https://github.com/Immediate-Mode-UI/Nuklear/wiki/Window
        if (nk_begin(ctx, "Nuklear", nk_rect(100, 100, 220, 220),
                NK_WINDOW_BORDER|NK_WINDOW_MOVABLE|NK_WINDOW_CLOSABLE)) {
            nk_layout_row_static(ctx, 50, 150, 1);
            //Random text to make the scrollbar appear
            nk_label(ctx, "Lorem Ipsum", NK_LEFT);
            nk_label(ctx, "Lorem Ipsum", NK_LEFT);
            nk_label(ctx, "Lorem Ipsum", NK_LEFT);
            nk_label(ctx, "Lorem Ipsum", NK_LEFT);
        }
        nk_end(ctx);

        // Render
        BeginDrawing();
            ClearBackground(GRAY);

            int active = nk_item_is_any_active(ctx);
            DrawText(activeText[active], 400, 200, 20, GREEN);

            // Render the Nuklear GUI
            DrawNuklear(ctx);

        EndDrawing();
    }

    // De-initialize the Nuklear GUI
    UnloadNuklear(ctx);

    CloseWindow();
    return 0;
}
