Good evening. To specifically state what I am trying to accomplish, I would like to create a dynamic table of data that when a table cell is pressed, a slot will increment some variable.

I have a table of strings with corresponding table cells. I want to use these table cells with a mouse event (.clicked()) as a signal and a lambda expression as slot. However, I want all of the tablecell mouse event signals to correspond to 1 slot. Also, the table is dynamic so I would like for the signal and slot to be connected when the tablecell is created.

What I have so far is a lambda expression that is a slot that adds the task from a lineedit to the grid when the add task button is pressed. Easy. Next I need to bind each tablecell to a slot that increments a variable when pressed. I have attempted many ways of binding many signals to 1 slot with boost bind and std::bind to no avail. I've used different methods and a few times I have come up with being able to connect only the last tablecell to be created at the time to the slot. I believe my best attempt is when I tried to make a vector of function objects to act as many slots corresponding to many signals dynamically as follows:

//TCells is a vectors of tablecell pointers

//Task adder is the slot that adds the task to the table

//addbutton is the button connected to a mouse event as a signal

static std::vector<std::function<void()>> functors;

auto TaskAdder = [=]{

this~~taskText = this>taskEdit->displayText();

thistaskTextStr = this>taskText.toUTF8();

Sboard->AddTasker(taskTextStr);

if(Sboard->flag == 1){

thisAddTask(Sboard>GridStrings);

Sboard->flag = 0;

}

functors.push_back([this] { MovesTextsetText(std::to_string(this>numMoves)); });

thisTCells[this>size - 2]clicked().connect(std::bind(functors[this~~>toDoCount]));

this->toDoCount;

};

addButton->clicked().connect(std::bind(TaskAdder));

This allows me to only increment the numMoves when the last tablecell is clicked. Not other table cells.

A similar attempt that had the same outcome that I found in the forums is:

auto TasktoProgress = [=]{

MovesText~~setText(std::to_string(this~~>numMoves));

};

auto TaskAdder = [=]{

this~~taskText = this>taskEdit->displayText();

thistaskTextStr = this>taskText.toUTF8();

Sboard->AddTasker(taskTextStr);

if(Sboard->flag == 1){

thisAddTask(Sboard~~>GridStrings);

Sboard->flag = 0;

}

this~~TCells[this~~>size - 2]->clicked().connect(std::bind(TasktoProgress));

};

addButton->clicked().connect(std::bind(TaskAdder));

Please help. I can't find any information online that helps me solve the problem of many signals to 1 slot. Thank you for reading.
