How to create a HyperLink in Qt 4.1.5?

[vishal.chauhan]

Hi All,

I m using Qt 4.1.5 on my Intel Mac.
I want to create a Link in Qt. I can make a Link in Qt 4.2.2 but Actually QT 4.2.2 does not give support to MAC 10.2 so I have to use Qt 4.1.5.

So If anybody knws then plz help me.

Thanks.

Sub class QPushButton

reimplement all of these events

virtual void enterEvent(QEvent *);
virtual void leaveEvent(QEvent *);
virtual void paintEvent(QPaintEvent *);

You can change mouse cursor when mouse enter
and change back when mouse leave

painter use for Draw Text look like link color

Or use a QLabel or QWidget to do the same thing, because QPushButton is too "heavy" for such a small task.

To copy to clipboard, switch view to plain text mode

ONLY on MAC!
IMO...
if you show last line from http://www.qtforum.de/forum/viewtopic.php?t=2366 only source ...

you can make applescript and set image backround or other 1000 way applescript ... like make a coffe...

Patrick... the question was about Qt 4.1. And it was about displaying a link and not opening pdf files...

[vishal.chauhan]

Thanks for Reply.

But as Wysota said question was how to create hyperlink in Qt 4.1.5 not in Qt 4.2.
