question: how to get data like html or svg

[loudoweb]

Hi, I would like to get the html text and not the raw text. How I can dot that? I also would like to get data from graphic software (like photoshop) which I suppose is svg (but I'm not sure).

I tried to register with the following mime type without success (is_convertible returns false):

clip::format html_format = clip::register_format("text/html");
clip::format rich_format = clip::register_format("text/richtext");
clip::format svg_format = clip::register_format("image/svg+xml");

Is there a way to get these formats?

Also, is it possible to get the list of the current formats in the clipboard?

Just a little update about html format. I found that the correct format for html should be HTML Format and not text/html. But length is 0, so still unusable.

 clip::format html_format = clip::register_format("HTML Format"); 
l.is_convertible(html_format ))//return true when having html in clipboard
size_t len = l.get_data_length(html_format);//return 0

I can get the html using directly windows api:

int cfid = RegisterClipboardFormat("HTML Format");
OpenClipboard(NULL);
HGLOBAL   hglb = GetClipboardData(cfid); 
if (hglb != NULL) 
{ 
      std::cout << "raw " << (char*)hglb << " \n";
}

With the CLIP api, I've made little progress, it seems that the clipboard wasn't opened (or something like that) but now instead of having get_data_length giving 0, the assertion fails len <= total_size, file ..\clip_win.cpp, line 387

Finally, in Windows I found that it is possible to list the current formats stored in the clipboard (if registered) so I guess it would possible to add this feature in the api (at least for windows):

UINT uFormat; 
LPCSTR lpFormatName = NULL; 
char szFormatName[80]; 

uFormat = EnumClipboardFormats(0); 
 
    while (uFormat) 
    { 
        if (lpFormatName == NULL) 
        {
            if (GetClipboardFormatName(uFormat, szFormatName, sizeof(szFormatName))) 
                lpFormatName = szFormatName; 
            else 
                lpFormatName = "(unknown)"; 

          std::cout << "has format: '" << lpFormatName << "'\n";
        } 
        uFormat = EnumClipboardFormats(uFormat); 
    }

Hi @loudoweb, actually the API doesn't give the possibility to list all formats, but it's something I needed in the past for debugging purposes and I would like to create a little app to check the clipboard content in detail. So it's something I would like to add.

About the html format. The get_data_length() function returns 0 because it returns the required data size depending on the format (text or custom). So it's not prepared for a general purposes / any kind of clipboard content, but it could be expanded for that case.

Thanks for your answer @dacap . So if I can't use get_data_length to get the length, how could I use get_data ?

At the moment the API is not made for general purpose clipboard content. So it's something to implement.
