Display filesystem to load a file and drawing an image

maveganzones · #1 05-Apr-2005, 11:27

Hi again, i had two new problems:

1. I want to draw a jpeg file in a box. How can i do it? Im doing this but it dosn't work.

CPP / C++ / C Code:

void IU_em::draw() {
  // Tengo guardada la imagen en una estructura >Ipl_Image de la que extraigo data, size y step.
  fl_draw_image((uchar*)data, imagen_box->x(), imagen_box->y(), size.width, size.height, 3, step);
  imagen_box->redraw();
}

2. How can i get a filesystem display window so i can give the choose of loading a file? Just like the browse... usually window.

Thanks

Hello and Welcome to GIDForums™ maveganzones. A few bits of information are needed.

What version of FLTK are you working with?
Show a more of the code so we can play along at home.

Do you just want to show random pictures or some that you have in mind? We could whip up something like the attached image without much trouble. I have a dir full of playing cards that will work well. That way the dimentions are fixed and it will be easier to show the example.

To get the image off disk you could use Fl_File_Chooser.

Hi Cable_guy and thanks for the responses.

I have solved the problem about showing images in a box, but i dont know how the FL_File_Browser works. What I want its to load an image from a file of the user choose, can you help me with an example, please? I would thank you a lot.

Greetings

I have fixed it with the Fl_File_Chooser widget. Im going to post a thread explaining how to use the Fl_File_Chooser widget and making some questions about it.

Thanks
