Exception when i'm trying to create ComboBox in "3D" UI

[Dreikblack]

Works fine in usual interface but throws an exception in case of UI in 3D rendering viewport.

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 640, 480, displays[0]);

    // Create a world
    auto world = CreateWorld();

    // Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create ui camera
    auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetPosition(float(framebuffer->GetSize().x) * 0.5f, float(framebuffer->GetSize().y) * 0.5f, 0);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetClearMode(CLEAR_DEPTH);

    //Load a font
    auto font = LoadFont("Fonts/arial.ttf");

    //Create user interface
    auto ui = CreateInterface(world, font, framebuffer->GetSize());
    ui->SetRenderLayers(2);
    ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);

    //Create widget
    auto sz = ui->root->ClientSize();
    auto combobox = CreateComboBox((sz.x - 300) / 2, (sz.y - 30) / 2, 300, 30, ui->root);
    for (int n = 0; n < 20; ++n)
    {
        combobox->AddItem("Item " + String(n), n == 0);
    }

    while (true)
    {
        const Event ev = WaitEvent();
        switch (ev.id)
        {
        case EVENT_WIDGETSELECT:
            Print("Item " + String(ev.data) + " selected");
            break;
        case EVENT_WINDOWCLOSE:
            return 0;
            break;
        }
    }
}

The fix is incoming. Example for testing:

#include "UltraEngine.h"

using namespace UltraEngine;

int main(int argc, const char* argv[])
{
    //Get the displays
    auto displays = GetDisplays();

    //Create a window
    auto window = CreateWindow("Ultra Engine", 0, 0, 640, 480, displays[0]);

    // Create a world
    auto world = CreateWorld();

    // Create a framebuffer
    auto framebuffer = CreateFramebuffer(window);

    //Create ui camera
    auto uiCamera = CreateCamera(world, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetPosition(float(framebuffer->GetSize().x) * 0.5f, float(framebuffer->GetSize().y) * 0.5f, 0);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetClearMode(CLEAR_DEPTH);

    //Load a font
    auto font = LoadFont("Fonts/arial.ttf");

    //Create user interface
    auto ui = CreateInterface(world, font, framebuffer->GetSize());
    ui->SetRenderLayers(2);
    
    auto button = CreateButton("TEST", 20, 20, 400, 30, ui->background);

    //Create widget
    auto sz = ui->root->ClientSize();
    auto combobox = CreateComboBox((sz.x - 300) / 2, (sz.y - 30) / 2 + 100, 300, 30, ui->root);
    for (int n = 0; n < 20; ++n)
    {
        combobox->AddItem("Item " + String(n), n == 0);
    }

    while (true)
    {
        const Event ev = WaitEvent();
        switch (ev.id)
        {
        case EVENT_WIDGETSELECT:
            Print("Item " + String(ev.data) + " selected");
            break;
        case EVENT_WINDOWCLOSE:
            return 0;
            break;
        default:
            ui->ProcessEvent(ev);
            break;
        }

        world->Update();
        world->Render(framebuffer);
    }
}
