Passing QLabel as an argument in a function error: invalid use of non-static data mem

[bbishoplt1]

Ok so I am building a GUI for a Rubik's Solving Robot. I am currently working on developing the GUI to be able to click the squares of the rubiks cube and they change colors to the correct color. I am using a grid with QLabels that I want to pass to my function to do the processing.



MainWindow.h

In my header file I have :

void mouse_pressed(int i, int j,QLabel* cubieface);

void mouse_pressed(int i, int j,QLabel* cubieface);

To copy to clipboard, switch view to plain text mode 

MainWindow.cpp

// This is my function for Left Face 0 cube and I want to pass the int i, j for the position of the array cube[6][9] and QLabel name so I can update the setPixMap(Color) when the Mouse is pressed. The function will change the color of the square based on the # in the array. :
 
void MainWindow::l_f_0_clicked()
{
    this->mouse_pressed(1,0,Ui_MainWindow::cubie_left_0);       // This is where the problem arises :mad:  line 44 error in code
}
 
// Mouse Pressed function
void MainWindow::mouse_pressed(int i, int j, QLabel *cubieface)
{
 
    QPixmap whitepix("/Users/RubiksGUI/white.png");
    QPixmap redpix("/Users/RubiksGUI/red.png");
    QPixmap greenpix("/Users/RubiksGUI/green.png");
    QPixmap yellowpix("/Users/RubiksGUI/yellow.png");
    QPixmap orangepix("/Users/RubiksGUI/orange.png");
    QPixmap bluepix("/Users/RubiksGUI/blue.png");
    if(cubedev[i][j]==5)
    {
        cubieface->setPixmap(whitepix); //:mad: Also once corrected this is usually ui->cubieface->setPixmap(color) but isnt throwing an error for it without the ui-> part
        cubedev[i][j]=0;
 
    }
    else if(cubedev[i][j]==0)
    {
        cubieface->setPixmap(redpix);
        cubedev[i][j]+=1;
 
    }

// This is my function for Left Face 0 cube and I want to pass the int i, j for the position of the array cube[6][9] and QLabel name so I can update the setPixMap(Color) when the Mouse is pressed. The function will change the color of the square based on the # in the array. :

void MainWindow::l_f_0_clicked()
{
    this->mouse_pressed(1,0,Ui_MainWindow::cubie_left_0);       // This is where the problem arises :mad:  line 44 error in code
}

// Mouse Pressed function
void MainWindow::mouse_pressed(int i, int j, QLabel *cubieface)
{

    QPixmap whitepix("/Users/RubiksGUI/white.png");
    QPixmap redpix("/Users/RubiksGUI/red.png");
    QPixmap greenpix("/Users/RubiksGUI/green.png");
    QPixmap yellowpix("/Users/RubiksGUI/yellow.png");
    QPixmap orangepix("/Users/RubiksGUI/orange.png");
    QPixmap bluepix("/Users/RubiksGUI/blue.png");
    if(cubedev[i][j]==5)
    {
        cubieface->setPixmap(whitepix); //:mad: Also once corrected this is usually ui->cubieface->setPixmap(color) but isnt throwing an error for it without the ui-> part
        cubedev[i][j]=0;

    }
    else if(cubedev[i][j]==0)
    {
        cubieface->setPixmap(redpix);
        cubedev[i][j]+=1;

    }

To copy to clipboard, switch view to plain text mode 

... Etc for each case. My problem is the function l_f_0_clicked() wont pass the QLabel.

Error : ../RubiksGUI/mainwindow.cpp:62:44: error: invalid use of non-static data member 'cubie_left_0'
this->mouse_pressed(1,0,Ui_MainWindow::cubie_left_0);


HELP PLEASE!!!!!
