Hi, i have QWidget and i want him to disappear duration X time. In qt my code
works:
...
Thank you!
Cheers,
Maxim
Code:
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QPushButton>
#include <QPropertyAnimation>
#include <QGraphicsEffect>
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
QGraphicsOpacityEffect *eff = new QGraphicsOpacityEffect();
ui->pushButton->setGraphicsEffect(eff);
QPropertyAnimation *a = new QPropertyAnimation(eff,"opacity");
a->setDuration(3500);
a->setStartValue(0);
a->setEndValue(1);
a->setEasingCurve(QEasingCurve::InCubic);
a->start(QPropertyAnimation::DeleteWhenStopped);
//connect(a,SIGNAL(finished()),this,SLOT(hideThisWidget()));
connect(ui->pushButton, SIGNAL(clicked(bool)), this, SLOT(hideButton()) );
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::hideButton()
{
QGraphicsOpacityEffect *eff = new QGraphicsOpacityEffect();
ui->pushButton->setGraphicsEffect(eff);
QPropertyAnimation *a = new QPropertyAnimation(eff,"opacity");
a->setDuration(3500);
a->setStartValue(1);
a->setEndValue(0);
a->setEasingCurve(QEasingCurve::OutBack);
a->start(QPropertyAnimation::DeleteWhenStopped);
}
but then i use this code with OSG, he doesn't work.
The window where everything happens is osgViewer::CompositeViewer.
How can I solve this problem?
