> What do I make wrong?
I'm not sure - can you post a minimal, compileable, example that shows
the failing behaviour?
Here's a simple example that *does* work...
//
// fltk1-3-config --use-images --compile scroll-test.cxx
//
#include <FL/Fl.H>
#include <FL/Fl_JPEG_Image.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Scroll.H>
#include <FL/Fl_Box.H>
//
// Show how to make a scrollable image view
//
int main(int argc, char **argv) {
if(argc < 2) {
puts("Filename?");
return -1;
}
// load a jpeg image
Fl_JPEG_Image picture(argv[1]);
// Create the windows and widgets
Fl_Double_Window win(150, 150);
win.begin();
Fl_Scroll scroll(10, 10, win.w() - 20, win.h() - 20);
scroll.begin();
Fl_Box *img_box = new Fl_Box(0, 0, picture.w(), picture.h());
img_box->image(picture);
scroll.end();
win.end();
win.resizable(scroll);
win.show();
return Fl::run();
}
