Browsing search text upwards and downwards

[ChrisW67]

Probably a combination of SCi_SETCURRENTPOS(), SCI_SETANCHOR() and SCI_SCROLLCARET().

I would probably have used the Scintilla searching functions to locate the text.

Thanks As suggested by you,
I modified code block as follows.

void searchText( const QString& sText, bool bDown)
{
	QString data = m_pTextEdit->text();
	m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICATORCLEARRANGE, 0, data.length());
 
	if (sText.isEmpty())
	{
		return;
	}
 
    int index = data.indexOf(sText, 0,  Qt::CaseInsensitive);
	int length = sText.length();
 
	if (bDown == true)
	{
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SETANCHOR, index);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SETCURRENTPOS, index);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SCROLLCARET, 0);
		edit_SearchText->setFocus();
	}
 
    while (index >= 0) {
       	m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICSETSTYLE,0 ,QsciScintilla::INDIC_ROUNDBOX);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICSETFORE, 0x007f00);
 
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICATORFILLRANGE, index, length);
		index = data.indexOf(sText, index + length, Qt::CaseInsensitive);	 
    }
}

void searchText( const QString& sText, bool bDown)
{
	QString data = m_pTextEdit->text();
	m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICATORCLEARRANGE, 0, data.length());
	
	if (sText.isEmpty())
	{
		return;
	}

    int index = data.indexOf(sText, 0,  Qt::CaseInsensitive);
	int length = sText.length();

	if (bDown == true)
	{
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SETANCHOR, index);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SETCURRENTPOS, index);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_SCROLLCARET, 0);
		edit_SearchText->setFocus();
	}
	
    while (index >= 0) {
       	m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICSETSTYLE,0 ,QsciScintilla::INDIC_ROUNDBOX);
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICSETFORE, 0x007f00);
		
		m_pTextEdit->SendScintilla(QsciScintilla::SCI_INDICATORFILLRANGE, index, length);
		index = data.indexOf(sText, index + length, Qt::CaseInsensitive);	 
    }
}

To copy to clipboard, switch view to plain text mode 

Still no luck of moving selection to next occurrence when search down key is pressed.
