How to draw selectable text with QPainter?

I need to implement a class like QGraphcisTextItem, however I need it to be selectable text.

However if my class descends from QGraphicsTextItem or QGraphicsItem, and I reimplement the paint event the ability for the text to be selectable is lost (I'm using drawText).

So my question is how can I create selectable text using QPainter's drawText?

Solution

  • I can't reproduce the issue you have with custom fonts. That's a very important bit of information that belongs in the question and changes the question substantially.

    The addApplicationFont is a static function that adds the font to the application-wide font database. Use the applicationFontFamilies(int id) to obtain the name of the family to use in html:

    ...
auto id = QFontDatabase::addApplicationFont(":/fonts/myfont.ttf");
if (if == -1)
  return;
auto families = QFontDatabase::applicationFontFamilies(id);
if (families.isEmpty())
  return;
auto face = families.first().toHtmlEscaped();
auto html = QStringLiteral("<font face=\"%1\">Hello</font>").arg(face);
...
