refreshing QPixmap

[Wojtek.wk]

Hi!
Is it possible to refresh the picture viewed by QPixmap? I have the QPixmap object with given picture and when I'll click the button it should refresh (because in the meantime this picture has changed)... I've looked in API for something like this, but with no result.
Thanks in advance!

QPixmap in representation of data in the mem, so you don't display pixmap but view pixmap in i.e. qlabel. Do something like this:

QPixmap px;
px.load("image1.ext");
ui->label->setPixmap(px);
 
//and on button press 
px.load("image2.ext");
//or
//QByteArray ByteArrayImage;
//px.loadFromData( ByteArrayImage );
ui->label->setPixmap(px);

QPixmap px;
px.load("image1.ext");
ui->label->setPixmap(px);

//and on button press 
px.load("image2.ext");
//or
//QByteArray ByteArrayImage;
//px.loadFromData( ByteArrayImage );
ui->label->setPixmap(px);

To copy to clipboard, switch view to plain text mode 

EDIT: You could use, on button press, something like this also:

ui->label->setScaledContents( false );
    ui->label->update( ui->label->rect() );
    ui->label->setScaledContents( true );

ui->label->setScaledContents( false );
    ui->label->update( ui->label->rect() );
    ui->label->setScaledContents( true );

To copy to clipboard, switch view to plain text mode 

or repaint. If you don't setScaledContents(false) then true image don't show, assuming that scaledContents was true.
