It would be great to have opportunity handle click on header cells. For example for sorting some data. 

There is std::function<> in modern C++. Of course there are also could be some templates tricks for works with variadic arguments but in base it's std::function.

A control{s} to select a file{directory} path. Sometimes it's called as File{Dir}Picker but more popular name is OpenFile{Folder}Dialog.

right, it's indeed works, thank you.

Is it possible to set position for widgets inside grid to keep it straight(i.e. on one row/column)?
When there is only one column better don't use grid at all, but it should be possible for multiple columns.

#include <TGUI/TGUI.hpp>
#include <random>
#include <string>

std::string random_str()
{
std::string str("0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz");

std::random_device rd;
std::mt19937 gen(rd());
std::uniform_int_distribution<> dis(0, 32);
std::shuffle(str.begin(), str.end(), gen);
return str.substr(0, dis(gen));
}

{
sf::RenderWindow window(sf::VideoMode(800, 600), "TGUI window");
tgui::Gui gui(window);
auto panel = tgui::ScrollablePanel::create();
auto grid = tgui::Grid::create();

for (std::size_t i = 0; i < 20; i++)
{
auto cbox = tgui::Label::create(random_str());
//panel->add(cbox, std::to_string(i));
grid->addWidget(cbox, i, 0);
if (i != 0)
{
auto prev = grid->getWidget(i - 1, 0);
//auto prev = panel->get(std::to_string(i - 1));//works without grid
if (prev != nullptr)
{
cbox->setPosition({ tgui::bindLeft(prev), tgui::bindBottom(prev) });
}
}
}

panel->add(grid);
gui.add(panel);
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();

gui.handleEvent(event); // Pass the event to the widgets
}

window.clear();
gui.draw(); // Draw all widgets
window.display();
}
}

P.S. I read this topic but it's didn't help 

O, now I see. Silly mistake, thank you.

I want to create a MessageBox on menu click and close it via Cancel button. But calling close in ButtonPressed handler cause a crash. How it to do correctly?

#include <TGUI/TGUI.hpp>

static auto Edit = L"Edit";

int main()

sf::RenderWindow window(sf::VideoMode(800, 600), "TGUI window");
tgui::Gui gui(window);
tgui::MenuBar::Ptr menuBar = tgui::MenuBar::create();

menuBar->addMenu(Edit);
menuBar->addMenuItem(Edit, L"Apply");
menuBar->connectMenuItem({ Edit, L"Apply" }, [&gui]
{
auto ptr = tgui::MessageBox::create("Title", "Some warning", { "OK", "Cancel" });
gui.add(ptr);
ptr->connect("ButtonPressed", [&](const std::string& button)
{
if (button == "OK")
{
std::cout << "OK\n";
}
else if (button == "Cancel")
{
ptr->close();
}
});
});

gui.add(menuBar);

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

gui.handleEvent(event); // Pass the event to the widgets
}

window.clear();
gui.draw(); // Draw all widgets
window.display();
}
}

You can load widgets from file:

Code Select Expand

gui.loadWidgetsFromFile("form.txt");

Thanks it works, I didn't know about group. I looking through tutorials and examples but didn't found anything related to it. When one should use group and not just layouts?

I tried set position only for layout without using group and this works too.   

I can't found a way to insert space between menu bar and panel with other widgets because without it they overlapped. How to do it correctly?

#include <TGUI/TGUI.hpp>

int main()

sf::RenderWindow window(sf::VideoMode(400, 300), "TGUI window");
tgui::Gui gui(window);
auto topLayout = tgui::VerticalLayout::create();
auto panel = tgui::ScrollablePanel::create();
auto grid = tgui::Grid::create();

tgui::MenuBar::Ptr menuBar = tgui::MenuBar::create();
menuBar->addMenu(File);
menuBar->addMenuItem(File, L"New");
menuBar->addMenuItem(File, L"Open");
gui.add(menuBar);
auto box = tgui::CheckBox::create("0");
grid->addWidget(box, 0, 0);
auto box2 = tgui::CheckBox::create("1");
grid->addWidget(box2, 1, 0);
panel->add(grid);
gui.add(grid);
topLayout->add(panel);
gui.add(topLayout);
menuBar->moveToFront();
// Main loop
while (window.isOpen())
{
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
window.close();

gui.handleEvent(event); // Pass the event to the widgets
}
window.clear();
gui.draw(); // Draw all widgets
window.display();
}
}

Yes, I'm used to menu bars that separate from frame so idea put it to layout was attempted make it works. At begin I didn't use layout at all and there was my mistake.

Yeah moveToFront works well, thanks for answer.

Menu items don't show when I press on a menu. Menubar is added into layout. Is this expected behaviour or bug? If it's first case - how to fix?

tgui::MenuBar::Ptr menuBar = tgui::MenuBar::create();
menuBar->addMenu("File");
menuBar->addMenuItem("File", "New");

topLayout->add(menuBar);
topLayout->add(tgui::Button::create("Button"));
gui.add(topLayout);

while (window.isOpen())
{
sf::Event event;

window.close();

gui.handleEvent(event); // Pass the event to the widgets
}

window.clear();
gui.draw(); // Draw all widgets
window.display();
}
}

It's a very common controls so it would be great have opportunity use them from builder.

Can you provide MCVE (Minimal Complete Verifiable Example) for reproducing the behaviour?
