there is a way, but "quick and simple" seems a bit euphemistic to me.
You can get the windows content out of the draw-function and then save
it, when you know how. :o)
First a point out how to use the draw:
#include <FL/Fl_Double_Window.H>
#include <FL/fl_draw.H>
#include <FL/x.H>
#include <write_png.h>
class Fl_Screenshot_Window: public Fl_Double_Window
{
public:
Fl_Screenshot_Window(int x, int y, int w, int h, const char*l= 0):
Fl_Double_Window(x, y, w, h, l)
{}
Fl_Screenshot_Window(int w, int h, const char*l= 0):
Fl_Double_Window(w, h, l)
{}
protected:
void draw()
{
Fl_Double_Windwo::draw();
if (unsigned char* pImage= fl_read_image(0, 0, 0, w(), h(), 0))
{
write_png("/home/ed/temp/image.png", pImage, w(), h(), 3);
delete[] pImage;
}
}
};
When you use this window-class, it will copy every draw to "image.png".
Beside this code you need to include "libpng.a" or "libflt_kpng.a".
