Replace text smiley with images in QListView

psbhardwaj09gmail.com

Hi

In my case QString textMessage ="hello <img_src="../emoticons/cute.png">""; is not the problem.

textMessage is not getting displayed in messageRect.

but when i am using
@doc->drawContents(painter); @

instead of
@doc->drawContents(painter, messageRect);@
textMessage is displaying in QListView. But there is also a problem that when i again add another message to list then it gets overlapped with old one.

Rgds,
Pardeep

ok i see ... try this:
@
void ConversationViewItemDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option) const
{
painter->save();
....
painter->translate( option.rect.topLeft() );

 QTextDocument *doc = new QTextDocument();
       doc->setHtml(textMessage);
        doc->drawContents(painter, messageRect);
 painter->restore();

}

To add to raven_worx, are you sure that your images can be found ? Using relative path can be tricky

How should anyone even know what problem you have?!

I meant the problem presented in this thread

the thread author stopped responding in this thread...
Maybe you can provide a minimal compileable example. I am pretty sure it's a small thing missing to make the example form above to work.

Ok raven. Here is the part of the code that is working but not as expected;

@
....

QRect messageContentRect = messageFontMetrics.boundingRect(textOffset4,
rect.top() + textHeightInPixels + 13,
rect.width() - (textOffset4) - dateTimeTextWidthInPixels - 5 - 10 , 0,
Qt::AlignLeft | Qt::AlignTop | Qt::TextWrapAnywhere,
messageContent);

painter->setPen(QColor("#363636"));
messageContent = smilifyMessage(messageContent);
QTextDocument *doc = new QTextDocument();
doc->setHtml(messageContent);
//painter->drawText(messageContentRect, Qt::AlignLeft | Qt::AlignTop |Qt::TextWrapAnywhere, //messageContent, &actuallyUsedRectForMessage);
doc->drawContents(painter, messageContentRect);

    ....

QPainter::drawText () is working as expected and messages shown in the view. But if I use QTextDocument::drawContents() method instead, then messages are not shown.
