Hey there,
I'm using the precompiled TGUI v0.7-alpha2 for Visual C++14 (2015) 32 bit with SFML-2.3.2. I have linked it static.
Since I just had started using this awesome library, I copied the example code (
https://tgui.eu/example-code/v0.7/scalable-login-screen/) for the scalable login screen and modified it to produce the error.
The scalable screen worked well when I directly attached the widgets to the gui like in the original example, but when I have started using the tgui::VerticalLayout things get a bit wired.
When I uncomment line 21 where I insert a space in between the two buttons in the layout, it will throw a assertion error when you scale the window on the y axis. Scaling on the x axis works perfectly. It also works perfect if there is no space in the layout or if I don't use a layout at all.
The error occours in line 56 when
gui.setView(window.getView()); is called.
The exact error:
Debug Assertion Failed!
File: [...]\Microsoft Visual Studio\14.0\VC\include\vector
Line: 101
Vector iterator not incrementable
The release mode will also throw an error, but a little bit different.
The code used to get this error:
(mostly the example)
#include <TGUI/TGUI.hpp>
void loadWidgets(tgui::Gui& gui)
{
// Create GUI
// Update size on window resize
auto windowWidth = tgui::bindWidth(gui);
auto windowHeight = tgui::bindHeight(gui);
// Vertical Layout
auto MenuLayout = std::make_shared<tgui::VerticalLayout>();
MenuLayout->setSize(windowWidth * 0.6f, windowHeight * 0.8f);
MenuLayout->setPosition(windowWidth * 0.2f, windowHeight * 0.1f);
gui.add(MenuLayout);
// Play Button
auto PlayBtn = std::make_shared<tgui::Button>();
//MenuLayout->add(PlayBtn);
/* ### Error line ### */
MenuLayout->addSpace(0.5f);
// Exit Button
auto ExitBtn = std::make_shared<tgui::Button>();
MenuLayout->add(ExitBtn);
}
int main()
{
// Create the window
sf::RenderWindow window(sf::VideoMode(400, 300), "TGUI window");
tgui::Gui gui(window);
try {
// Load the font
gui.setFont("Arial.ttf");
// Load the widgets
loadWidgets(gui);
} catch(const tgui::Exception& e) {
std::cerr << "Failed to load TGUI widgets: " << e.what() << std::endl;
return 1;
}
// Main loop
while(window.isOpen()) {
sf::Event event;
while(window.pollEvent(event)) {
// When the window is closed, the application ends
if(event.type == sf::Event::Closed)
window.close();
// When the window is resized, the view is changed
else if(event.type == sf::Event::Resized) {
window.setView(sf::View(sf::FloatRect(0, 0, event.size.width, event.size.height)));
gui.setView(window.getView());
}
// Pass the event to all the widgets
gui.handleEvent(event);
}
window.clear();
// Draw all created widgets
gui.draw();
window.display();
}
return EXIT_SUCCESS;
}Thanks for your help
