resize a QGraphicsRectItem

[gbmtoday]

Hi there

I have QGraphicsRectItem and I want to resize it , but I can't.

I tried this , but it doesnt work

QRectF rect ( player->shape()->pos().x() ,
                 (player->shape()->pos().y()+WINDOW_END_H)/2.0,
                 PLAYER_WIDTH_P,
                 PLAYER_HEIGHT_P/2.0);
 
    player->shape()->setRect(rect);

QRectF rect ( player->shape()->pos().x() ,
                 (player->shape()->pos().y()+WINDOW_END_H)/2.0,
                 PLAYER_WIDTH_P,
                 PLAYER_HEIGHT_P/2.0);

    player->shape()->setRect(rect);

To copy to clipboard, switch view to plain text mode 

player->shape() returns a QGraphicsRectItem *

I just want to change the hight of the rect to a half .

I tried this , too

player->shape()->rect().setHeight(player->shape()->rect().height() / 2.0 );

player->shape()->rect().setHeight(player->shape()->rect().height() / 2.0 );

To copy to clipboard, switch view to plain text mode 

It doesnt work too .

Do you know what is the problem?
