Description
The QTouchEvent works perfectly with only one finger, with two fingers it works nearly as expected, i mean i receive a second TouchUpdate when i put the second finger on the screen. After i lift one of the two finger off the screen i get no TouchUpdate.
Minimum Compilable Example:
- mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
protected slots:
bool event(QEvent *event);
private:
Ui::MainWindow *ui;
};
#endif // MAINWINDOW_H
- mainwindow.cpp
#include "mainwindow.h" #include "ui_mainwindow.h" #include <QTouchEvent> #include <QEvent> #include <QDebug> MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); QWidget::setAttribute(Qt::WA_AcceptTouchEvents); QWidget::setAttribute(Qt::WA_StaticContents); } MainWindow::~MainWindow() { delete ui; } bool MainWindow::event(QEvent *event) { qDebug() << event->type(); switch(event->type()) { case QEvent::TouchBegin: { QTouchEvent *te = static_cast <QTouchEvent *>(event); int x = te->touchPoints().size(); qDebug() << x; } break; case QEvent::TouchUpdate: { QTouchEvent *te = static_cast <QTouchEvent *>(event); int x = te->touchPoints().size(); qDebug() << x; } break; case QEvent::TouchEnd: { QTouchEvent *te = static_cast <QTouchEvent *>(event); int x = te->touchPoints().size(); qDebug() << x; } break; default: return true; } return true; }
