Custom dialog

[spirit]

here is an example with opacity animation (if I understand you correctly)

void Test::setLabelOpacity(int opacity)
{
	m_label->setWindowOpacity(opacity / 100.0);
}
 
void Test::showLabel()
{
	QPixmap pixmap(300, 300);
	QPainter painter(&pixmap);
	QRectF rectangle(0.0, 0.0, 299.0, 299.0);
	painter.setBrush(Qt::red);
	painter.setPen(Qt::red);
	painter.drawRoundedRect(rectangle, 20.0, 15.0);
 
	m_label = new QLabel();
	m_label->setMask(QBitmap(pixmap));
	m_label->setPixmap(pixmap);
	m_label->setAttribute(Qt::WA_DeleteOnClose);
 
 
	QTimeLine *timeLine = new QTimeLine(1000, this);
	timeLine->setCurveShape(QTimeLine::LinearCurve);
	timeLine->setFrameRange(0, 100);
	connect(timeLine, SIGNAL(frameChanged(int)), SLOT(setLabelOpacity(int)));
	timeLine->start();
 
	m_label->setWindowOpacity(0);
	m_label->show();
}

void Test::setLabelOpacity(int opacity)
{
	m_label->setWindowOpacity(opacity / 100.0);
}

void Test::showLabel()
{
	QPixmap pixmap(300, 300);
	QPainter painter(&pixmap);
	QRectF rectangle(0.0, 0.0, 299.0, 299.0);
	painter.setBrush(Qt::red);
	painter.setPen(Qt::red);
	painter.drawRoundedRect(rectangle, 20.0, 15.0);

	m_label = new QLabel();
	m_label->setMask(QBitmap(pixmap));
	m_label->setPixmap(pixmap);
	m_label->setAttribute(Qt::WA_DeleteOnClose);


	QTimeLine *timeLine = new QTimeLine(1000, this);
	timeLine->setCurveShape(QTimeLine::LinearCurve);
	timeLine->setFrameRange(0, 100);
	connect(timeLine, SIGNAL(frameChanged(int)), SLOT(setLabelOpacity(int)));
	timeLine->start();

	m_label->setWindowOpacity(0);
	m_label->show();
}

u can have closeEvent() of your custom dialog like this to achieve that:

void CustomDialog::closeEvent(QCloseEvent *event)
{
   QEventLoop el;
   QTimeLine *timeLine = new QTimeLine(1000, this);
    timeLine->setCurveShape(QTimeLine::LinearCurve);//u can change this curve shape to achieve different effects, read QTimeLine
    timeLine->setFrameRange(0, 100);
    connect(timeLine, SIGNAL(frameChanged(int)),this, SLOT(setLabelOpacity(int)));
    connect(timeLine, SIGNAL(finished()),el,  SLOT(quit()));
    timeLine->start();
    el.exec();
    QDialog::closeEvent(event);
}
 
void CustomDialog::setLabelOpacity(int opacity)
{
    setWindowOpacity(opacity / 100.0);
}

void CustomDialog::closeEvent(QCloseEvent *event)
{
   QEventLoop el;
   QTimeLine *timeLine = new QTimeLine(1000, this);
    timeLine->setCurveShape(QTimeLine::LinearCurve);//u can change this curve shape to achieve different effects, read QTimeLine
    timeLine->setFrameRange(0, 100);
    connect(timeLine, SIGNAL(frameChanged(int)),this, SLOT(setLabelOpacity(int)));
    connect(timeLine, SIGNAL(finished()),el,  SLOT(quit()));
    timeLine->start();
    el.exec();
    QDialog::closeEvent(event);
}

void CustomDialog::setLabelOpacity(int opacity)
{
    setWindowOpacity(opacity / 100.0);
}

i havent tested it but it should work
