An example of using base iterator in C++

Posted by | C++ |

The code below demonstrates how to access underlying range iterator by transformed iterator:

struct A
{
    int x;
};

struct B
{
    A* a;
};

std::vector<B> v;

int main()
{
    auto a_range = v | std::views::transform(std::mem_fn(&B::a));

    auto i = std::ranges::find(a_range, 5, std::mem_fn(&A::x));

    A* a = *i;

    B& b = *(i.base());
}

Make QML menu width fit the content

Posted by | QML, QT |

Found an implementation here and added two pixels:

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts

Menu {
    width: {
        var result = 0;
        var padding = 0;
        for (var i = 0; i < count; ++i) {
            var item = itemAt(i);
            result = Math.max(item.contentItem.implicitWidth, result);
            padding = Math.max(item.padding, padding);
        }
        // It looks like two pixels are missing to remove the ellipsis.
        // My first idea was that it is leftInset + rightInset, but it does not work.
        var missing = 2;
        return result + padding * 2 + missing;
    }
}
