i draw a colorpanel used the below code ,but how to get the color from mouse move event?


void ColorPanel::paintEvent(QPaintEvent *event)
{

QPainter painter(this);

QStringList colors;

You are two steps away:

1. The mouse event functions are separate from the paint functions, so the color data will need to be available outside the paint event. As a general rule I like to keep event handling and data in separate routines, but for this example, I've just moved the color list data into a member variable.

2. You need to re-implement mouse event handling. There, you can calculate the index by remapping from the widget pixel coordinates to the the row/column of the grid being drawn.




class ColorPanel : public QWidget
{
Q_OBJECT

public:
ColorPanel(QWidget *parent = 0);

signals:
void colorHighlightedChanged( QColor color );
void indexHighlightedChanged( int index );

protected:
void paintEvent(QPaintEvent *event);
void mouseMoveEvent(QMouseEvent *event);

private:
int indexHighlighted;

QStringList colors;

int widthCount;
int heightCount;
QRect* boxSize;

};





ColorPanel::ColorPanel( QWidget* parent ) :
QWidget( parent )
{
indexHighlighted = -1;

setMouseTracking(true);

widthCount = 15;
heightCount = 15;
boxSize = new QRect(0, 0, 7, 7);

colors<<"FFFFFF"<<"FFFAFA"<<"FFF68F"<<"FFEFD5"<<"FFE4E1"<<"FFDEAD"<<"FFC1C1"<<"FFB90F"<<"FFA54F "<<"FF8C00 "<<"FF7F50 "<<"FF6EB4 "<<"FF4500 "<<"FF3030 "<<"FDF5E6 "<<"FAF0E6 "<<"F7F7F7 "<<"F5DEB3 "<<"F0FFFF "<<"F0E68C "<<"EEEE00 "<<"EEE8AA "<<"EEDFCC "<<"EED5B7 "<<"EEC900 "<<"EEAEEE "<<"EE9A49 "<<"EE8262 "<<"EE7621 "<<"EE6363 "<<"EE3A8C "<<"EE00EE "<<"EAEAEA "<<"E5E5E5 "<<"E0EEE0 "<<"DEB887 "<<"DBDBDB "<<"D9D9D9 "<<"D3D3D3 "<<"D1D1D1 "<<"CDCDC1 "<<"CDC9A5 "<<"CDC1C5 "<<"CDB7B5 "<<"CDAF95 "<<"CD9B1D "<<"CD8C95 "<<"CD7054 "<<"CD661D "<<"CD5B45 "<<"CD3333 "<<"CD1076 "<<"CAFF70 "<<"C71585 "<<"C4C4C4 "<<"C1CDC1 "<<"BFBFBF "<<"BDB76B "<<"BBFFFF "<<"B8B8B8 "<<"B4EEB4 "<<"B3B3B3 "<<"B0E2FF "<<"B03060 "<<"ADADAD "<<"A9A9A9 "<<"A4D3EE "<<"A1A1A1 "<<"9F79EE "<<"9B30FF "<<"9A32CD "<<"98F5FF "<<"949494 "<<"912CEE "<<"8EE5EE "<<"8DEEEE "<<"8B8B7A "<<"8B8878 "<<"8B8378 "<<"8B7D6B "<<"8B7500 "<<"8B668B "<<"8B5A2B "<<"8B4789 "<<"8B4500 "<<"8B3626 "<<"8B1C62 "<<"8B0000 "<<"87CEFF "<<"858585 "<<"838B83 "<<"7FFF00 "<<"7D7D7D "<<"7B68EE "<<"7A67EE "<<"778899 "<<"737373 "<<"707070 "<<"6CA6CD "<<"6A5ACD "<<"6959CD "<<"66CD00 "<<"63B8FF "<<"5F9EA0 "<<"5C5C5C "<<"556B2F "<<"548B54 "<<"525252 "<<"4EEE94 "<<"4A4A4A "<<"474747 "<<"458B00 "<<"424242 "<<"3D3D3D "<<"388E8E "<<"333333 "<<"2E8B57 "<<"282828 "<<"228B22 "<<"1F1F1F "<<"1C1C1C "<<"171717 "<<"0F0F0F "<<"050505 "<<"00FF00 "<<"00EE76 "<<"00CDCD "<<"00BFFF "<<"008B45 "<<"006400 "<<"0000AA"
