Thank you for your help! I got a lot further, but still not completely there. I
now have a window coming up. When it comes up, it has the "hello world" widget
inside, but when I close the window using the window-manager's close button (X
decoration), the console produces "X I/O error".
bash-3.1$ ./fltktest
X I/O error
bash-3.1$
#include <fltk/Window.h>
#include <fltk/run.h>
#include <fltk/x11.h>
#include <X11/Xlib.h>
#include <unistd.h>
class twindow : public fltk::Window {
public:
twindow(int x, int y) : fltk::Window(x,y) {
}
virtual ~twindow() {}
virtual void create() {
fltk::open_display();
XWindow win = XCreateSimpleWindow(fltk::xdisplay,
RootWindow(fltk::xdisplay, fltk::xscreen), 0, 0, 500, 500, 0, 0, 0);
XMapWindow(fltk::xdisplay, win);
XFlush(fltk::xdisplay);
fltk::CreatedWindow::set_xid(this, win);
}
};
int main(int argc, char* argv[]) {
twindow x(500,500);
x.begin();
fltk::Widget *box = new fltk::Widget(20, 40, 260, 100, "Hello, World!");
box->box(fltk::UP_BOX);
box->labelfont(fltk::HELVETICA_BOLD_ITALIC);
box->labelsize(36);
box->labeltype(fltk::SHADOW_LABEL);
x.end();
x.show();
fltk::run();
return 0;
}
