Drag Drop Images from WebPage into QTextEdit

Hi guys,

Does QTextEdit have support for images copied from Web ? I mean when a user cut/copies/pastes data from the Web, I end up with place holders in my richtextbox editor which I have derived from QTextEdit. I tried overwriting canInsertfromMimeData and insertFromMimeData, the code segment for source->hasImage() does not execute. I even used the source->hasHtml() this seems to work fine but yet no Images. Any help will be appreciated. Thanks in advance!!

subclass QTextEdit insertFromMimedata or so ...

here a sample ....

Code:

---

void TextWriter::insertFromMime( const QMimeData * source )
{
 
	  if ( source->formats().contains("application/x-picslists") ) {
         /* multiple image list */
			 QByteArray dd = source->data("application/x-picslists"); 
			 QList<SPics> li = OpenImageGroup(QString(dd));
			      for (int i=0; i<li.size(); i++) {
                 SPics conni = li[i];
							   RegisterImage(conni,true);
             }
			return;
		}
    if ( source->hasImage() ) {
         QDateTime timer1( QDateTime::currentDateTime() );
         const QString TimestampsMs = QString("%1-%2-image").arg(timer1.toTime_t()).arg(timer1.toString("zzz"));
         QPixmap aspixmape = qvariant_cast<QPixmap>(source->imageData());
                if (!aspixmape.isNull()) {
                insertPixmap(aspixmape);
                }
         return;
    }
    /* external html  */
 
    if ( source->formats().contains("text/html") ) {
         QString draghtml = source->html();
         QTextDocumentFragment fragment = QTextDocumentFragment::fromHtml(draghtml);
         textCursor().insertFragment(fragment);
         return;
    }
    /* external plain text incomming   */
      if ( source->hasText() )  {
        textCursor().insertText(source->text());
        return;
      }
      if ( source->hasUrls() )  {
          QList<QUrl> urls = source->urls();
          for ( int i = 0; i < urls.size(); ++i ) { 
          QUrl gettyurl(urls.at(i));
				 //////////// qDebug() << "### gettyurl " << gettyurl.toString();
              if (gettyurl.scheme() == "file") {
                  ImageonCursor(gettyurl.toLocalFile()); 
              } else if (gettyurl.scheme() == "http") {
                      Gloader *grephttp = new Gloader();
                      grephttp->Setting(this,i,gettyurl); 
                      grephttp->start(QThread::LowPriority);
 
                      /* grep class Gloader on 
                                    http://fop-miniscribus.googlecode.com/svn/trunk/GraphicsViewEdit/include/mimedataeditor.h
                    */
 
              }
 
          }
 
        return;          
      }
 
 
}

Did you mean [WIKI]Drop files and images on QTextEdit[/WIKI]? :)

Eeem.... yeah, I think I did :)

Yeah!! I had checked that out before, no go! See I will explain what is happening. When I dragging just text there is not issue, Just dragging images no text it okay. Only when I just Ctrl + A or Just select Text and Pics together thats when I hit the problem. Now I have an idea what to do ...if I can get just get the <img> tags and then download the images to a temp location and then changes the src of the <img> to these images I will be okay. But the issue how do I get the <img> tags, you like an html editor without having to parse ( find replace ? ) the html. ( yeah, yeah ...I am lazy) :)

See thread "QTextEdit and delayed image loading".

Hello All,
I am new to Qt. In my project, I am also coming up with same issue. I will want to copy contents (contents include text, images combined) from a web page or any external source and paste in my qtextedit. But, images are not getting displayed and only the text gets pasted. If I copy images alone and try to paste, it is displayed in qtextedit :confused:. If I am correct, the issue is related to collecting mimedata. When I copy image alone, mimedata format is stored as Image. But it doesn't work when trying to copy text and image together. I wish that someone will help me to resolve this issue.

Thanks
Viswanathan
