Problem finding text in a QTextEdit

[Lykurg]

Hi,

void VashTextEditor::find()
{
	FindDialog findDialog(this);
	if (!findDialog.exec())
		return;
 
	const QString searchString = findDialog.getSearchString();
	bool test = documentEdit->find(searchString);
 
	if (test)
	{
		QMessageBox::information(this, tr("Vash Text Editor"), tr("Expression found."));
	}
	else
	{
		QMessageBox::information(this, tr("Vash Text Editor"), tr("Expression not found."));
	}
}

void VashTextEditor::find()
{
	FindDialog findDialog(this);
	if (!findDialog.exec())
		return;
		
	const QString searchString = findDialog.getSearchString();
	bool test = documentEdit->find(searchString);
	
	if (test)
	{
		QMessageBox::information(this, tr("Vash Text Editor"), tr("Expression found."));
	}
	else
	{
		QMessageBox::information(this, tr("Vash Text Editor"), tr("Expression not found."));
	}
}

To copy to clipboard, switch view to plain text mode 

Seems fine, but to debug what does following code produce (at the end of your function)?

qWarning() << searchString;
qWarning() << documentEdit->toPlainText();
qWarning() << documentEdit->textCursor()->position();

qWarning() << searchString;
qWarning() << documentEdit->toPlainText();
qWarning() << documentEdit->textCursor()->position();

To copy to clipboard, switch view to plain text mode 

void FindDialog::toggleFindButton()
{
	QString currentText = findLineEdit->text();
 
	if (!currentText.isEmpty())
	{
		findButton->setEnabled(true);
	}
	else
	{
		findButton->setEnabled(false);
	}
}

void FindDialog::toggleFindButton()
{
	QString currentText = findLineEdit->text();
	
	if (!currentText.isEmpty())
	{
		findButton->setEnabled(true);
	}
	else
	{
		findButton->setEnabled(false);
	}
}

To copy to clipboard, switch view to plain text mode 

findButton->setEnabled(!findLineEdit->text().isEmpty());

findButton->setEnabled(!findLineEdit->text().isEmpty());

To copy to clipboard, switch view to plain text mode 

does the same.

P.s.: Expected is a normal string, no regular expression.

After adding the qWarning calls, this is what i get for output.

$ ./VashTextEditor 
"test"   <-- qWarning() << searchString
"test"   <-- qWarning() << documentEdit->toPlainText()

$ ./VashTextEditor 
"test"   <-- qWarning() << searchString
"test"   <-- qWarning() << documentEdit->toPlainText()

So it looks like it is returning the right value from my dialog, and my document edit is showing that the text is there, but it is still returning false on my find.

and what is

qWarning() << documentEdit->textCursor()->position();

qWarning() << documentEdit->textCursor()->position();

saying? before opening your search dialag make sure that the text cursor is at the front of the text. If then still is false return please make a minimal compilable example and post it.

if it is still not working you may want use the advanced option of QTextDocument. (-> QTextEdit::document())

I'm sorry.
My suggestion was wrong.


I made a sample that uses QTextEdit::find().
It works fine.

Thanks so much for that, I didn't even think to check about where the text cursor was. It is working now. Thanks a bunch to everyone who helped.
