Both of those solutions did not work. Here is my first try with QWidget:
#include "headers/piece.h"
#include <QPainter>
#include <QMouseEvent>
#include <QBitmap>
#include <QCursor>
using namespace std;
Piece
::Piece(string color, string piece,
QWidget *parent
) :{
this->piece = piece;
this->color = color;
this->setMaximumHeight(36);
this->setMaximumWidth(36);
x = 0;
y = 0;
setMouseTracking(false);
}
{
string image = ":/images/" + color + piece + ".png";
pixmap.load(image.c_str());
//pixmap.setMask(pixmap.createMaskFromColor(QColor(240, 240, 240)));
paint.drawPixmap(0, 0, pixmap);
}
void Piece::setPosition(int file, int rank)
{
pixmap.load(":/images/whitepawn.png");
QImage image
= pixmap.
toImage();
x = (file-1)*50 + 18;// - image.width()/2;
y = (rank-1)*50 + 18;// - image.height()/2;
move(x, y);
}
{
if(event->buttons() == Qt::LeftButton)
{
x = event->globalX()-18;
y = event->globalY()-18;
move(x,y);
}
}
#include "headers/piece.h"
#include <QPainter>
#include <QMouseEvent>
#include <QBitmap>
#include <QCursor>
using namespace std;
Piece::Piece(string color, string piece, QWidget *parent) :
QWidget(parent)
{
this->piece = piece;
this->color = color;
this->setMaximumHeight(36);
this->setMaximumWidth(36);
x = 0;
y = 0;
setMouseTracking(false);
}
void Piece::paintEvent(QPaintEvent *)
{
string image = ":/images/" + color + piece + ".png";
pixmap.load(image.c_str());
//pixmap.setMask(pixmap.createMaskFromColor(QColor(240, 240, 240)));
QPainter paint(this);
paint.drawPixmap(0, 0, pixmap);
}
void Piece::setPosition(int file, int rank)
{
pixmap.load(":/images/whitepawn.png");
QImage image = pixmap.toImage();
x = (file-1)*50 + 18;// - image.width()/2;
y = (rank-1)*50 + 18;// - image.height()/2;
move(x, y);
}
void Piece::mouseMoveEvent(QMouseEvent *event)
{
if(event->buttons() == Qt::LeftButton)
{
x = event->globalX()-18;
y = event->globalY()-18;
move(x,y);
}
}

Here's how it looks with QGraphicsItem:
#include "piece2.h"
#include <QPainter>
#include <QMouseEvent>
#include <QBitmap>
#include <QCursor>
#include <QGraphicsSceneMouseEvent>
using namespace std;
Piece2
::Piece2(string color, string piece,
QObject *parent
) :{
this->piece = piece;
this->color = color;
//this->setMaximumHeight(36);
//this->setMaximumWidth(36);
x = 0;
y = 0;
//setMouseTracking(false);
}
{
string image = ":/images/" + color + piece + ".png";
pixmap.load(image.c_str());
//pixmap.setMask(pixmap.createMaskFromColor(QColor(240, 240, 240)));
//QPainter paint(this);
painter->drawPixmap(0, 0, pixmap);
}
void Piece2::setPosition(int file, int rank)
{
pixmap.load(":/images/whitepawn.png");
QImage image
= pixmap.
toImage();
x = (file-1)*50 + 18;// - image.width()/2;
y = (rank-1)*50 + 18;// - image.height()/2;
setPos(x, y);
}
{
if(event->buttons() == Qt::LeftButton)
{
// x = event->globalX()-18;
// y = event->globalY()-18;
setPos(x,y);
}
}
#include "piece2.h"
#include <QPainter>
#include <QMouseEvent>
#include <QBitmap>
#include <QCursor>
#include <QGraphicsSceneMouseEvent>
using namespace std;
Piece2::Piece2(string color, string piece, QObject *parent) :
QGraphicsItem()
{
this->piece = piece;
this->color = color;
//this->setMaximumHeight(36);
//this->setMaximumWidth(36);
x = 0;
y = 0;
//setMouseTracking(false);
}
void Piece2::paint(QPainter *painter, const QStyleOptionGraphicsItem *option, QWidget *widget)
{
string image = ":/images/" + color + piece + ".png";
pixmap.load(image.c_str());
//pixmap.setMask(pixmap.createMaskFromColor(QColor(240, 240, 240)));
//QPainter paint(this);
painter->drawPixmap(0, 0, pixmap);
}
void Piece2::setPosition(int file, int rank)
{
pixmap.load(":/images/whitepawn.png");
QImage image = pixmap.toImage();
x = (file-1)*50 + 18;// - image.width()/2;
y = (rank-1)*50 + 18;// - image.height()/2;
setPos(x, y);
}
void Piece2::mouseMoveEvent(QGraphicsSceneMouseEvent *event)
{
if(event->buttons() == Qt::LeftButton)
{
// x = event->globalX()-18;
// y = event->globalY()-18;
setPos(x,y);
}
}

With everything I try the image still has a white background instead of transparent.
