Creating a window in a window.

[Lolilolight]

Hi!

I need to create a window in a window for my game. (Confirmation and message dialogs.)

So I've just created this class :

OptionPane::OptionPane(math::Vec3f position, math::Vec3f size, const Font* font, sf::String t, TYPE type) :
                LightComponent (position, size, size * 0.5f, false),
                rw (sf::VideoMode(size.x, size.y), "Option Pane", sf::Style::Default, sf::ContextSettings(0, 0, 4, 3, 0)),
                type(type) {
                rw.getView().move(size.x * 0.5f, size.y * 0.5f, size.z * 0.5f);
                if (type == CONFIRMATION_DIALOG) {
                    yes = new Button(math::Vec2f(size.x / 100 * 70, size.y - 100), math::Vec2f(100, 50), font, "Yes", rw);
                    no = new Button(math::Vec2f(size.x / 100 * 10, size.y - 100), math::Vec2f(100, 50), font, "No", rw);
                    core::FastDelegate<bool> trigger1(&Button::isMouseInButton, yes);
                    core::FastDelegate<bool> trigger2(&Button::isMouseInButton, no);
                    core::FastDelegate<void> slot1(&OptionPane::onYesOption, this);
                    core::FastDelegate<void> slot2(&OptionPane::onNoOption, this);
                    core::Action a (core::Action::MOUSE_BUTTON_PRESSED_ONCE,sf::Mouse::Left);
                    core::Command cmd1 (a, trigger1, slot1);
                    core::Command cmd2 (a, trigger2, slot2);
                    getListener().connect("YESOPTION", cmd1);
                    getListener().connect("NOOPTION", cmd2);
                } else {
                    yes = nullptr;
                    no = nullptr;
                    core::Action a (core::Action::KEY_PRESSED_ONCE, sf::Keyboard::Return);
                    core::FastDelegate<void> slot(&OptionPane::onEnter, this);
                    core::Command cmd (a, slot);
                    getListener().connect("ONENTER", cmd);
                }
                rw.setPosition(sf::Vector2i(position.x, position.y));
                option = UNDEFINED;
                text.setFont(*font);
                text.setString(t);
                text.setColor(sf::Color::Black);
                text.setPosition(math::Vec3f(10, 10, position.z));
                text.setSize(size);
                backgroundColor = sf::Color::White;
            }
            void OptionPane::onVisibilityChanged(bool visible) {
                rw.setVisible(visible);
            }
            OptionPane::OPTION OptionPane::getOption() {
                OPTION choosenOption = option;
                option = UNDEFINED;
                return choosenOption;
            }
            void OptionPane::clear() {
                rw.clear(backgroundColor);
            }
            void OptionPane::draw(RenderTarget& target, RenderStates states) {
                if (rw.isOpen()) {
                    rw.draw(text, states);
                    if (type == CONFIRMATION_DIALOG)  {
                        rw.draw(*yes, states);
                        rw.draw(*no, states);
                    }
                    rw.display();
                }
            }
            void OptionPane::update() {
                sf::Event event;
                while(rw.pollEvent(event)) {
                    if (event.type == sf::Event::Closed) {
                        rw.setVisible(false);
                    }
                    getListener().pushEvent(event);
                }
            }
            void OptionPane::onEnter() {
                setVisible(false);
                setEventContextActivated(false);
                rw.setVisible(false);
            }
            void OptionPane::onYesOption() {
                rw.setVisible(false);
                setEventContextActivated(false);            
                option = YES_OPTION;
            }
            void OptionPane::onNoOption() {
                rw.setVisible(false);
                setEventContextActivated(false);            
                option = NO_OPTION;
            }
            void OptionPane::setText(std::string t) {
                text.setString(sf::String(t.c_str()));
            }
            OptionPane::~OptionPane() {
                rw.close();
                if (CONFIRMATION_DIALOG) {
                    delete yes;
                    delete no;
                }
            }
 

It works fine except for one point, here, I want to create two sub-windows :

m_pseudoUsed = new gui::OptionPane(Vec2f(200, 200), Vec2f(200, 100), fm.getResourceByAlias("FreeSerif"),"Pseudo already used!",gui::OptionPane::TYPE::MESSAGE_DIALOG);
    m_pseudoUsed->setVisible(false);
    m_pseudoUsed->setEventContextActivated(false);
    m_confirmInvitation = new gui::OptionPane(Vec2f(200, 200), Vec2f(200, 100), fm.getResourceByAlias("FreeSerif"),"",gui::OptionPane::TYPE::CONFIRMATION_DIALOG);
    m_confirmInvitation->setVisible(false);
    m_confirmInvitation->setEventContextActivated(false);
 

I set the visibility of my sub-windows to false, so the windows shouldn't be shown, but it's not what I see.

I see a transparent window on the main window, and the title is not always the title of my sub-windows..., this is really strange. :/

And here is a code which repoduce the bug :

int main()
{  
    RenderWindow window(sf::VideoMode(800, 600), "OpenGL");  
    RenderWindow window1(sf::VideoMode(200, 100), "test");
    window1.setVisible(false);
    RenderWindow window2(sf::VideoMode(200, 100), "test2");
    window2.setVisible(false);
    while (window.isOpen())
    {
        sf::Event event;
        while(window.pollEvent(event)) {
              if (event.type == sf::Event::Closed)
                    window.close();
        }
        window.clear();
        window.display();
    }
    return 0;
 

The second window is visible. :/ (The window which the title "test2")

does this works ?

#include <SFML/Graphics.hpp>
using namespace sf;

int main()
{
    RenderWindow window(sf::VideoMode(800, 600), "OpenGL");
    RenderWindow window1(sf::VideoMode(500, 100), "test");
    RenderWindow window2(sf::VideoMode(500, 100), "test2");

    bool once = true;

    while (window.isOpen())
    {
        sf::Event event;
        while(window.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window.close();
        }
        while(window1.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window1.close();
        }
        while(window2.pollEvent(event)) {
            if (event.type == sf::Event::Closed)
                window2.close();
        }

        if (once) {
            window1.setVisible(false);
            window2.setVisible(false);
            once = false;
        }

        window.clear();
        window.display();
    }
    return 0;
}

does this works ?

No.

OS? Version of SFML?

[Lolilolight]

OS version : Ubuntu LTS 14.4 (64 bits)

SFML version : SFML-master (the one from the git repository)

I've also tried with the last stable version but same problem.

Most easy way (if your using win32 and sfml 2.x) you can handle sf::RenderWindow to a HWND window and call message boxes for HWND window and make parent windows and in the same window draw sfml! Cool!

How is that helpful? He is not using win32 - he explicitly states that he's using  Ubuntu LTS 14.4  ...

Arf..., linux doesn't seems to be very appropriate to create more complex api. :/ (Or is  it SFML fault ?)

Now, I receive a keyreleased event even if I don't release a key, this is very annoying, I think this is related to the first bug because I don't have this problem with a single window.

And when I want to put the code to render into a thread (because the rendering time is too long with mesa opensource driver) I get the this non-sense error that I haven't called XinitThread but I've done it.

I think I'll use SDL instead of SFML to get rid of this bugs with the SFML window module but I don't know if it's possible to use opengl function manually after creating an SDL window, last time I tried the opengl function wheren't not executed.
