Can I implement this example in my program?

I-sty

"Your text to link here...":http://qt-project.org/doc/qt-4.8/widgets-codeeditor-codeeditor-h.html

I have a other program (other form, buttons, plaintextedites), and I would implement this to my plaintext.

How to?

JKSH

Which part do you want to implement? What do you want your program to do?

You can copy the code, as long as you follow the license at the top of the file.

I-sty

The all.

@
.....
ui->setupUi(this);

CodeEditor editor1;
editor1.setGeometry (15, 15, 300, 150);
editor1.show ();

}

MainWindow::~MainWindow()
{
delete ui;
}

CodeEditor::CodeEditor(QWidget *parent) : QPlainTextEdit(parent)
{
lineNumberArea = new LineNumberArea(this);

 connect(this, SIGNAL(blockCountChanged(int)), this, SLOT(updateLineNumberAreaWidth(int)));
 connect(this, SIGNAL(updateRequest(QRect,int)), this, SLOT(updateLineNumberArea(QRect,int)));
 connect(this, SIGNAL(cursorPositionChanged()), this, SLOT(highlightCurrentLine()));

 updateLineNumberAreaWidth(0);
 highlightCurrentLine();

}@

This is my code. But does not appear nothing. :(

I-sty

Okay, I solved.

@//it creates the two text boxes
CodeEditor *editor0 = new CodeEditor; //left side box
CodeEditor *editor1 = new CodeEditor; //right side box
//it uploads the text boxes in the main window
ui->textBoxLayout->addWidget (editor0, 0, 0);
ui->textBoxLayout->addWidget (editor1, 0, 0);@
