MouseEvent and colors

[arubagirl]

Hello,

I'm just new in C++ and now we have in school very difficult lessons which we need to make.
Here's one i just don't get working. We have a picture with lines, the lines must change color when i press the left or right mousebutton.

rightnow i've the code

void Hoofdscherm::mousePressEvent(QMouseEvent *event)
{
    Qt::MouseButtons pressed;
    pressed = event->button();
 
    if (pressed.button == Qt::LeftButton)
    {penKleur = Qt::green;}
    else
        if (pressed.button ==Qt::RightButton)
        {penKleur = Qt::yellow;}
}

void Hoofdscherm::mousePressEvent(QMouseEvent *event)
{
    Qt::MouseButtons pressed;
    pressed = event->button();

    if (pressed.button == Qt::LeftButton)
    {penKleur = Qt::green;}
    else
        if (pressed.button ==Qt::RightButton)
        {penKleur = Qt::yellow;}
}

To copy to clipboard, switch view to plain text mode 

it's not going to work. i know you can make it with switch but we didn't have that in school yet so it must be different.

Your code is not that bad.
Either change Qt::MouseButtons to Qt::MouseButton, or make sure you extract the mouse button you are looking from Qt::MouseButtons.
I assume your 'penKleur' is used in a paintEvent().
You can call update() at the end of the mouse event to cause new redering of the widget.

Man you are lucky to get to learn Qt in school....
