Detailed Description
A drop-in replacement for QLabel that displays hyperlinks.KURLLabel is a drop-in replacement for QLabel that handles text in a fashion similar to how an HTML widget handles hyperlinks. The text can be underlined (or not) and set to different colors. It can also "glow" (cycle colors) when the mouse passes over it.
KURLLabel also provides signals for several events, including the mouse leaving and entering the text area and all forms of mouse clicking.
By default KURLLabel accepts focus. When focused, standard focus rectangle is displayed as in HTML widget. Pressing Enter key accepts the focused label.
A typical usage would be something like so:
KURLLabel *address = new KURLLabel(this); address->setText("My homepage"); address->setURL("http://www.home.com/~me"); connect(address, SIGNAL(leftClickedURL(const QString&)), SLOT(processMyURL(const QString&)));
In this example, the text "My homepage" would be displayed as blue, underlined text. When the mouse passed over it, it would "glow" red. When the user clicks on the text, the signal leftClickedURL() would be emitted with "http://www.home.com/~me" as its argument.

Constructor & Destructor Documentation
|
Default constructor. Use setURL() and setText() or QListView::setPixmap() to set the resp. properties. Definition at line 94 of file kurllabel.cpp. |
|
Convenience constructor.
parent and name are passed to QLabel, which in turn passes them further down
Definition at line 82 of file kurllabel.cpp. |

This feature is very similar to the "glow" feature in that the color of the label switches to the selected color when the cursor passes over it. In addition, underlining is turned on for as long as the mouse is overhead. Note that if "glow" and underlining are both already turned on, this feature will have no visible effect.
