Thank you for your advice. I have already tried this as I read in documentation
manual, but doesn´t work. I am using the dragging, so I need to save the state
when the mouse is pushed, but if I return 0, it just stops and do nothing (no
dragging).
Here is the sample code:
int BR_GLwindow::handle(int event)
{
switch(event)
{
case FL_MOVE:
mousePoint =
drawingPlan.intersection(camera.unprojectFar(Fl::event_x(),Fl::event_y()),camera.unprojectNear(Fl::event_x(),Fl::event_y()));
this->redraw();
return 1;
case FL_PUSH:
mouseClickX = Fl::event_x();
mouseClickY = Fl::event_y();
if(Fl::event_button()==1)
picking(Fl::event_x(),Fl::event_y());
return 1;//IF I PUT 0 HERE, IT DOESN´T WORK
case FL_MOUSEWHEEL:
camera.zoom(exp(Fl::event_dy()*0.08));
this->redraw();
return 1;
case FL_DRAG:
if (Fl::event_button() == 2)
{
camera.move(Fl::event_x(),Fl::event_y(),mouseClickX,mouseClickY);
this->redraw();
mouseClickX=Fl::event_x();
mouseClickY=Fl::event_y();
return 0;
}
if (Fl::event_button() == 3)
{
camera.rotate(Fl::event_x(),Fl::event_y(),mouseClickX,mouseClickY);
this->redraw();
mouseClickX=Fl::event_x();
mouseClickY=Fl::event_y();
return 1;
}
For the handle function in the main window, can I just write it like this?
int main(int argc, char **argv) {
Fl_Window *window = new Fl_Window(500,500);
BR_GLwindow brglwindow(10,10,480,400,0,&objects);
***...***
window->resizable(&brglwindow);
window->end();
window->show(argc, argv);
return Fl::run();
}
int handle(int event)
{
switch(event)
{
case FL_RELEASE:
std::cout<<"test";
return 1;
***...***
}
