ignore following link in anchorClicked()

[jh]

hi,

i have a qtextbrowser which shows some text with hrefs. clicking on a link
a new widget should be created and be shown. the link is not an url but only
a string which is interpreted in a slot connected to anchorClicked().
problem is that the textbrowser handles navigation automatically when
setSource is not be called in the slot. actually, i want the textbrowser do
nothing, i.e. i connect anchorClicked() to a slot, do something with the passed
string in the slot but the textbrowser should not do anything.
any chance to turn off the default handling of anchors?

best regards,
jh

Did you try disconnecting the anchorClicked signal from the setSource slot?

yes. in that case the textbrowser is cleared.

the textbrowser should do nothing except emiting signal anchorClicked.
even if i disconnect everthing (textBrowser->disconnect()) the textbrowser
is cleared.

try

"<a href = \"#\">your text here</a>"

Clicking on the link will only emit the signal and do nothing else.

unfortunately this also did not not work. same behaviour. textbrowser is cleared.

so i did the following:
- adding an anchor name to each link.
- in method 'follow_link(const QUrl&)' which is connected to
signal 'anchorClicked()' i set an empty url as source an scroll to the
named anchor:

part of the method which generates the html text which is shown in the textbrowser:

...
  str += "<tr bgcolor=\"#dddddd\"><td>ID</td><td colspan=\"3\">";
  str += "<a ";
  str += "name=\"" + obj->ID() + "\" ";
  str += "href=\"" + obj->ID() + "\">";
  str += obj->ID() + "</a></td></tr>";
  ...

...
  str += "<tr bgcolor=\"#dddddd\"><td>ID</td><td colspan=\"3\">";
  str += "<a ";
  str += "name=\"" + obj->ID() + "\" ";
  str += "href=\"" + obj->ID() + "\">";
  str += obj->ID() + "</a></td></tr>";
  ...

To copy to clipboard, switch view to plain text mode 

this method gets an clicked link (which containes the ID of
an object) and opens a new widget.

void Object_Widget::followLink(const QUrl& url)
{
  // textbrowser shows the same document but scrolls to the top
  textBrowser_properties->setSource(QUrl());
  //  scroll to the link which was clicked
  textBrowser_properties->scrollToAnchor(url.toString());
 
  try {
    model::Object& obj = model::System::object(url.toString());
    model_gui::SingleObject_Widget* so = 
      new model_gui::SingleObject_Widget(0,Qt::WindowStaysOnTopHint);
    so->object(&obj);
    so->show();
  } catch (model::NoSuchObject_Exception e) {
  }
}

void Object_Widget::followLink(const QUrl& url)
{
  // textbrowser shows the same document but scrolls to the top
  textBrowser_properties->setSource(QUrl());
  //  scroll to the link which was clicked
  textBrowser_properties->scrollToAnchor(url.toString());

  try {
    model::Object& obj = model::System::object(url.toString());
    model_gui::SingleObject_Widget* so = 
      new model_gui::SingleObject_Widget(0,Qt::WindowStaysOnTopHint);
    so->object(&obj);
    so->show();
  } catch (model::NoSuchObject_Exception e) {
  }
}

this works for me but getting rid of that automatic following of
links would be much better i think.
