/**
@brief A generic implementation of the "replace" function.
<b></b>etail:
This class includes prompt handling etc. Also provides some
static functions which can be used to create custom behavior
instead of using the class directly.
<b></b>xample:
To use the class to implement a complete replace feature:
In the slot connect to the replace action, after using KReplaceDialog:
<pre>
// This creates a replace-on-prompt dialog if needed.
m_replace = new KReplace(pattern, replacement, options, this);
// Connect signals to code which handles highlighting
// of found text, and on-the-fly replacement.
connect( m_replace, SIGNAL("highlight( String, int, int )"),
this, SLOT("slotHighlight( String, int, int )") );
// Connect findNext signal - called when pressing the button in the dialog
connect( m_replace, SIGNAL("findNext()"),
this, SLOT("slotReplaceNext()") );
// Connect replace signal - called when doing a replacement
connect( m_replace, SIGNAL("replace(String, int, int, int)"),
this, SLOT("slotReplace(String, int, int, int)") );
</pre>
Then initialize the variables determining the "current position"
(to the cursor, if the option FromCursor is set,
to the beginning of the selection if the option SelectedText is set,
and to the beginning of the document otherwise).
Initialize the "end of search" variables as well (end of doc or end of selection).
Swap begin and end if FindBackwards.
Finally, call slotReplaceNext();
<pre>
void slotReplaceNext()
{
KFind.Result res = KFind.NoMatch;
while ( res == KFind.NoMatch && <position not at end> ) {
if ( m_replace.needData() )
m_replace.setData( <current text fragment> );
// Let KReplace inspect the text fragment, and display a dialog if a match is found
res = m_replace.replace();
if ( res == KFind.NoMatch ) {
<Move to the next text fragment, honoring the FindBackwards setting for the direction>
}
}
if ( res == KFind.NoMatch ) // i.e. at end
<Call either m_replace.displayFinalDialog(); delete m_replace; m_replace = null;
or if ( m_replace.shouldRestart() ) { reinit (w/o FromCursor) and call slotReplaceNext(); }
else { m_replace.closeReplaceNextDialog(); }>
}
</pre>
Don't forget delete m_find in the destructor of your class,
unless you gave it a parent widget on construction.
See {@link KReplaceSignals} for signals emitted by KReplace
