You are passing the settings to the lambda by reference (because of the "&"), but settings is a local object. After the "menu.create(gui);" call, the settings object has been destroyed. When the button is pressed, you will be accessing an object that no longer exists.

But why it doesn't crash when i use only buttons? (For test i have deleted all the checkboxes and comboboxes from Settings::create). For example, one of buttons:

Code Select Expand

guifactory.button(context, 20, 1.2, 2.5, 10, "guiexit", "Exit");
tgui::Button::Ptr exitbutton = context.get<tgui::Button>("Exit");
exitbutton->connect("pressed", [&]() {
mainmenu.create(context);
});

And can you give me advice how to properly pass TGUI context to other functions?

Firstly i trying to initiate SFML and TGUI:

Code Select Expand

int main()
{
//Tons of code
Window window;
window.startUp();
window.createWindow();
}

Code Select Expand


void Window::createWindow()
{
sf::RenderWindow window{ { 800, 600 }, "Window" };
window.setFramerateLimit(60);
tgui::Gui gui{ window };

MainMenu menu;
menu.create(gui);

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

gui.handleEvent(event);
}

window.clear(sf::Color::White);
gui.draw();
window.display();
}
// Tons of code
}
Then i send a reference of TGUI context (gui) to another function where i trying to create main game menu:

Code Select Expand


void MainMenu::create(tgui::Gui & context)
{
context.removeAllWidgets();

GuiFactory guifactory;
Settings settings;

guifactory.button(context, 20, 4.5, 2.5, 10, "guisettings", "Settings");
tgui::Button::Ptr settingsbutton = context.get<tgui::Button>("Settings");
settingsbutton->connect("pressed", [&]() {
settings.create(context);
});
//Tons of unnecessary code
}

Code Select Expand


void Settings::create(tgui::Gui & context)
{
context.removeAllWidgets();

GuiFactory guifactory;

//Tons of unnecessary code
guifactory.checkbox(context, 20, 1.45, 28.0, 28.0, "settingsvsynccheckbox", "settingsvsynccheckbox", 0, 28);
tgui::CheckBox::Ptr settingsvsynccheckbox = context.get<tgui::CheckBox>("settingsvsynccheckbox");
if (getSettingBool("Fullscreen") == true) {
settingsvsynccheckbox->check();
}
else {
settingsvsynccheckbox->uncheck();
}
//Tons of unnecessary code

}
But when i push SettingsButton and application trying to render Settings Page i get a Nullptr error. Where my code gone wrong?
Btw, guifactory::checkbox and button methods:

void GuiFactory::checkbox(tgui::Gui & context, double xpos, double ypos, double xsize, double ysize, std::string text, std::string indentifier, int type, int size)
{
   auto windowWidth = tgui::bindWidth(context);
   auto windowHeight = tgui::bindHeight(context);

   Localization localization;
   auto checkbox = std::make_shared<tgui::CheckBox>();
   checkbox->setSize(xsize, ysize);
   checkbox->setText(localization.wtext(text));
   checkbox->setTextSize(size);
   if (type == 1) {
      checkbox->setPosition(xpos, ypos);
   }
   else {
      checkbox->setPosition(windowWidth / xpos, windowHeight / ypos);
   }
   context.add(checkbox);
}

Button->setSize(windowWidth / xsize, windowHeight / ysize);
Button->setText(localization.wtext(text));
Button->setTextSize(34);
context.add(Button, indentifier);
}
There is the same problem with comboboxes (i'm getting access violation error when trying to add any item), buttons work fine with it. If i add checkboxes and comboboxes as usual, then it works fine.
