我的窗口到全屏转换的时候会出现两便重画 由全屏转换到窗口 会出现4次重画代码如下：
void QIMPenWidget::changeScreenState() {
if( state == Normal ) {
resizeButton->setPixmap( Resource::loadPixmap( "shrinkscreen" ) );
resizeButton->setGeometry( 5, 5, 37, 32 );
state = Full;
reparent( 0, 0, QPoint(0,0), TRUE );
//qWarning("[Draft] show full screen");
showFullScreen();
// qWarning("[Draft] show full screen2");
clearButton->show();
//saveButton->show();
//leftButton->show();
//rightButton->show();
} else {
resizeButton->setPixmap( Resource::loadPixmap( "fullscreen" ) );
resizeButton->setGeometry( 3,9, 37, 32 );
state = Normal;
showNormal();
//qWarning("[Draft]show normal screan");
reparent( editorParent, 0, QPoint(0,0),TRUE );
//qWarning("[Draft]show normal screan2");
clearButton->hide();
//saveButton->hide();
//leftButton->hide();
//rightButton->hide();
}
初步估计是 reparent()函数引起的 但是不知道如何解决 希望高手能给予指点！谢谢！
