How to find QMenu by Path?

2022-01-21 10:31 Андрей Петров imported from Stackoverflow

I have QMenuBar with menu: File, New, Addons, Help. What I want to do: Menu with the name Addons is configurable. The user writes in console, for example, create_menu("Hello/world"), I need to create QMenu in Addons with the name "Hello" and Action in that menu with name world. If the user writes create_menu("Hello/world2") I need to add an action with the name "world2" in the menu Hello. Also i want to implement command to delete menus by that path. Now I have such a solution to create menus, but I what to find the simpler solution:

auto fspath = std::filesystem::path(path);
    std::function<std::pair<QMenu*, fs::path::iterator>(QMenu*, fs::path::iterator,
    fs::path::iterator)> enumerateMenu = [&enumerateMenu](auto menu, auto it, auto end)
    {
        foreach (QAction *action, menu->actions()) {
            if(it != end && (*it) == action->text().toStdString() && action->menu())
                return enumerateMenu(action->menu(), ++it, end);
        }
        return std::make_pair(menu, it);
    };
            
    auto menuPos = enumerateMenu(customMenu, fspath.begin(), fspath.end());
    auto submenu = menuPos.first;

    for(auto it  = menuPos.second;; ++it)
    {
        if(std::next(it) != fspath.end())
            submenu = submenu->addMenu(QString::fromUtf8((it->c_str())));
        else
        {
            auto actionsList = submenu->actions();
            auto pa = new QAction(QString::fromUtf8(it->c_str()), this);
            //connect(pa, &QAction::triggered, /*Not implemented*/);
            submenu->addAction(pa);
            break;
        }
    }

C++ increment with macro

I have the following code and I want to use increment with macro:

#include <iostream>

#define ABS(x) ((x) < 0 ? -(x) : (x))

int main(int argc, char** argv)
{
    int x = 5;
    const int result = ABS(x++);

    std::cout << "R: " << result << std::endl;
    std::cout << "X: " << x << std::endl;

    return EXIT_SUCCESS;
}

But output will be incorrect:

R: 6
X: 7

Is it possible to somehow use macros with an increment, or should this be abandoned altogether?

Can anyone pls tell me whats wrong with my code ? im stuck for the last 3 hours ,this question is bipartite graph in c++

idk why im getting error ,can someone help ? im trying to prove if a graph is bipartite or not in c++


bool isBipartite(vector<int> graph[],int V)
{
    vector<int> vis(V,0);
    vector<int> color(V,-1);
    
    color[0]=1;
    queue <int> q;
    q.push(0);
    while (!q.empty())
    {
        int temp = q.front();
        q.pop();
        for (int i=0;i<V;i++)
        {
            if (!vis[i] && color[i] == -1)   "if there is an edge, and colour is not assigned"
            {
                color[i] = 1 - color[temp];
                q.push(i);
                vis[i]=1;
            }
            else if (!vis[i] && color[i] == color[temp] "if there is an edge and both vertices have same colours"
            {
                vis[i]=1;
                return 0;                                // graph is not bipartite
            }
                
            
        }
    }
    return 1;
}

it gives output "no" for whatever i enter

How to assign two or more values to a QMap Variable in Qt
I am getting confused of how to store the values assigned from 3 different functions and storing them in a single map variable
```
QMap<QString,QString> TrainMap = nullptr;   
if(......)    
(    
       TrainMap    =    PrevDayTrainMap();
       TrainMap    =    NextDayTrainMap();
       TrainMap    =    CurrentDayTrainMap();
}
```
The PrevDayTrainMap,NextDayTrainMap & CurrentDayTrainMap returns a set of values with Date and the TrainIdName.I need to store all the values from prevday,currentday and nextday in the TrainMap but it stores only the currentday values to the TrainMap as it is assigned at the last.I am not sure what to do so that it doesn't overwrite.If I should merge what is the way to do it?

When to use qmake eval?

https://doc.qt.io/qt-5/qmake-test-function-reference.html

eval(string)

Evaluates the contents of the string using qmake syntax rules and returns true. Definitions and assignments can be used in the string to modify the values of existing variables or create new definitions.

For example:

eval(TARGET = myapp) {
    message($$TARGET)
}

I wondering when/why that should be used? Can't we just use TARGET = myapp directly?

How to use qmake.conf?

https://doc.qt.io/qt-5/qmake-environment-reference.html mentions qmake.conf, but how can I use it? What is the format? What would be one use case for it?
