Moving the View with the mouse (my solution)

[aitgelion]

After searching the best solution to move (scroll) the View using the mouse (pressing left button) I couldn't find anything that help me, so after spending some time trying, I have some usable solution.
Here it is if someone have the same problem!

Variables involved:
sf::Vector2f mouse(0,0); // global variable holding last position of the mouse
sf::View view; //the View asociated to the window

In the Switch handling the events:

Code: [Select]


while (Window.GetEvent(Event))
        {
            switch(Event.Type) {
                 .................

             case sf::Event::MouseMoved:
           if (!Window.GetInput().IsMouseButtonDown(sf::Mouse::Left)) {
mouse.x=Event.MouseMove.X;
mouse.y=Event.MouseMove.Y;
} else {
view.Move(mouse.x-Window.GetInput().GetMouseX(), mouse.y-Window.GetInput().GetMouseY());
mouse.x=Window.GetInput().GetMouseX();
mouse.y=Window.GetInput().GetMouseY();
}
break;
                       ...................
           }
}



Sure It may be some best aproach to do this, but it works for me!.

P.D.: I'm new so, Hello! ( and sorry for my level of english, I'm triying to improve it hehe)

EDIT: Sorry for posting at the wrong board.

How come the MouseMove event coordinates don't go negative? They seem to be absolute, or at least they are on windows.

The mouse coordinates are relative to the client area.
