#include "clip.h"
#include <iostream>

int main() {
  clip::set_text("Hello World");

  std::string value;
  clip::get_text(value);
  std::cout << value << "\n";
}

User-defined clipboard formats

#include "clip.h"

int main() {
  clip::format my_format =
    clip::register_format("com.appname.FormatName");

  int value = 32;

  clip::lock l;
  l.clear();
  l.set_data(clip::text_format(), "Alternative text for value 32");
  l.set_data(my_format, &value, sizeof(int));
}

Platform specific details

• If two versions of your application (32-bit and 64-bit) can run at at the same time, remember to avoid storing data types that could change depending on the platform (e.g. size_t) in your custom format data.
• Windows:
  • Limited number of clipboard formats on Windows
• Linux:
  • To be able to copy/paste on Linux you need libx11-dev/libX11-devel package.
  • To copy/paste images you will need libpng-dev/libpng-devel package.

• CLIP_ENABLE_IMAGE: Enables the support to copy/paste images.
• CLIP_ENABLE_LIST_FORMATS (only for Windows): Enables the clip::lock::list_formats() API function and the list_clip_formats example.
