{
private PictureBox obrazek;
private char typObrazka; //to jest char poniewaz kod planszy
skladac sie bedzie z ciagu literek, kazdy klocek jest
//charakteryzowany przez jeden char
private byte kolumna;
private byte wiersz;
private void DragDrop(object sender, DragEventArgs e)
{
this.obrazek.Image = (Bitmap)e.Data.GetData(typeof(Bitmap));
}
private void DragEnter(object sender, DragEventArgs e)
{
if (e.Data.GetDataPresent(typeof(Bitmap)))
{

}
else
{
e.Effect = DragDropEffects.None;
}

//imageList = aImageList;
kolumna = aKolumna;
wiersz = aWiersz;
obrazek = new PictureBox();
obrazek.Image = aImageList.Images[aTypObrazka - 97]; //-97
aby 'a' mialo indeks '0'
obrazek.SizeMode = PictureBoxSizeMode.StretchImage;
obrazek.Width = obrazekSzerokosc;
obrazek.Height = obrazekWysokosc;
obrazek.Left = aKolumna * obrazekSzerokosc;
