[QScintilla] Resetting search for replace

[Manuel Gómez]

Hi,

How should a search be canceled so a subsequent call to replace does 
nothing?

The following sequence would insert the searched text instead of 
actually replacing or doing nothing:

// user presses my find button
findFirst(...);

// user closes the find dialog
clearSelection();

// user opens again the find/replace dialog and clicks Replace
replace();

If I do this, the behaviour improves:

// user opens again the find/replace dialog and clicks replace
if (hasSelectedText())
     replace();

But if the user makes any selection before opening the dialog, the 
incorrect text is replaced, not fulfilling the searched term. Any better 
solution?

Regards,

Manuel
