Qt Gestures and Signals.
-
I was wondering how do you recognize gestures in Qt, and how to link actions to those gestures. I was thinking of making a signal that when the gesture(swipe) is made, it will trigger a slot(run a program). But I don't know how to make a signal(slot is made), and how to implement the gesture recognition in the code.
Edit: this is for Symbian^3 OS version Belle.

Are you using QML or plain C++ to implement your application UI? If you're using C++, you could inspect touch events directly, to perform gesture recognition. If you're using QML, you can use a MouseArea element, and use mouse.x and mouse.y data inside an onPressed handler.
As to how you recognise gestures, once you have access to the touch data, well, that's a rather more complex question.
Good luck!

Did you have a look at the documentation for QGesture & friends ?

Hey guys, to chriadam, I am using C++.
to morinehtar0 I tried to understand it but I still am a rookie. I know Java and Actionscript. But C++ is a bit different.
THANKS GUYS!!! just think I have Finished it!!!@
void MainWindow:: initialY(){
init=MouseLocator();
}
void MainWindow::finalY(){
fin=MouseLocator();
}
void MainWindow::action(){
if(fin-init<-500){
//put function here.
}
}int MainWindow::MouseLocator()
{
QPoint relativeMousePos = QCursor::pos();
int a=relativeMousePos.y();
return a;
}
@
Here is my code. initialY() runs when I press the button. finalY() runs when I release the button. also action() runs when I release my button. MouseLocator() just takes the mouse location at that instant. MY FIRST PROGRAM IN C++ And I have sort of imitated the Swipe gesture. Thanks guys!Edit: also the init and fin variables were global int variables. just to take in the Y value.
Edit: please use @ tags around code snippets; Andre
