After recreation with clearing a widgets thats stores in a vector of custom widgets are now visible

[Dreikblack]

Steam beta branch.

When i first time create widgets it's works. But when i destroy them and create new ones in a same vector they are invisible.

It worked several months ago. Need that for an inventory gui.

#include "UltraEngine.h"

using namespace UltraEngine;

class ContainerWidget : public Panel
{
    vector<shared_ptr<Widget>> btns;

protected:

    virtual bool Initialize(const int x, const int y, const int width, const int height, shared_ptr<Widget> parent)
    {
        btns.resize(4);
        return Widget::Initialize(text, x, y, width, height, parent, style);
    }

public:

    void initBtns() {
        clearBtns();
        for (int i = 0; i < btns.size(); i++)
        {
            btns[i] = CreateButton("Btn", i * 50 + 10, 0, 20, 20, Self()->As<Widget>());
        }
    }

    void clearBtns() {
        for (int i = 0; i < btns.size(); i++)
        {
            if (btns[i])
            {
                btns[i]->SetParent(nullptr);
                btns[i] = nullptr;
            }
        }
    }

    static shared_ptr<ContainerWidget> create(const int x, const int y, const int width, const int height, shared_ptr<Widget> parent)
    {
        struct Struct : public ContainerWidget {
        };
        auto instance = std::make_shared<Struct>();
        instance->Initialize(x, y, width, height, parent);
        instance->SetColor(0.5, 0.5, 0.5, 1, WIDGETCOLOR_BACKGROUND);
        instance->initBtns();
        return instance;
    }

};

shared_ptr<Window> window;
shared_ptr<Framebuffer> framebuffer;
shared_ptr<World> menuWold;
shared_ptr<Interface> ui;
shared_ptr<Camera> uiCamera;

shared_ptr<Widget> btn;
shared_ptr<ContainerWidget> container;

void initGui()
{
    auto default_font = LoadFont("Fonts\\arial.ttf");
    ui = CreateInterface(menuWold, default_font, framebuffer->GetSize());
    ui->SetRenderLayers(2);
    ui->root->SetColor(0.0f, 0.0f, 0.0f, 0.0f);
    uiCamera = CreateCamera(menuWold, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetPosition((float)framebuffer->GetSize().x * 0.5f, (float)framebuffer->GetSize().y * 0.5f, 0);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetClearMode(CLEAR_DEPTH);
    container = ContainerWidget::create(10, 50, 200, 50, ui->root);
    btn = CreateButton("Reinit buttons", 10, 10, 150, 20, ui->root);
}


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

    //Create a window
    window = CreateWindow("Ultra Engine", 0, 0, 300, 300, displays[0], WINDOW_DEFAULT);

    //Create a world
    menuWold = CreateWorld();

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

    //Create light
    auto light = CreateBoxLight(menuWold);
    light->SetRange(-10, 10);
    light->SetRotation(15, 15, 0);
    light->SetColor(2);

    //Create camera
    auto camera = CreateCamera(menuWold);
    camera->SetClearColor(0.125);
    camera->SetPosition(0, 0, -3);
    camera->SetFov(70);

    initGui();

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        while (PeekEvent())
        {
            const Event ev = WaitEvent();
            if (ev.source == btn && ev.id == EVENT_WIDGETACTION)
            {
                container->initBtns();
            }
            ui->ProcessEvent(ev);
        }
        menuWold->Update();
        menuWold->Render(framebuffer);
    }
    return 0;
}

BTW, you don't need to call Self()->As<Widget>(), you can just call As<Widget>().

Okay, I have simplified this and it appears to be some sort of clipping problem. Space key recreates the button:

#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, 300, 300, displays[0], WINDOW_DEFAULT);

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

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

    //Create camera
    auto camera = CreateCamera(menuWold);

    auto uiCamera = CreateCamera(menuWold, PROJECTION_ORTHOGRAPHIC);
    uiCamera->SetRenderLayers(2);
    uiCamera->SetPosition(framebuffer->size.x / 2.0f, framebuffer->size.y / 2.0f);

    auto ui = CreateInterface(menuWold, LoadFont("Fonts\\arial.ttf"), iVec2(300));
    ui->SetRenderLayers(2);

    //This works:
    //auto panel = CreatePanel(10, 19, 200, 50, ui->background);

    //This does not work:
    auto panel = CreatePanel(10, 20, 200, 50, ui->background);

    panel->SetColor(1, 0, 0, 1);

    auto btn = CreateButton("Btn", 10, 0, 20, 20, panel);

    //Main loop
    while (window->Closed() == false and window->KeyDown(KEY_ESCAPE) == false)
    {
        if (window->KeyHit(KEY_SPACE))
        {
            btn->SetParent(nullptr);
            btn = CreateButton(String(Random(100)), 10, 0, 20, 20, panel);
        }
        while (PeekEvent())
        {
            const Event ev = WaitEvent();
            ui->ProcessEvent(ev);
        }
        menuWold->Update();
        menuWold->Render(framebuffer);
    }
    return 0;
}

I believe this is fixed. Uploading now...
