• The following simple code snippet shows how to create and use QPushButton. It has been tested on Qt Symbian Simulator. An instance of QPushButton is created. Signal released is connected to slot handleButton which changes the text and the size of the button. To build and run the example: Create an empty folder.
• Under the GUI programming framework of Qt, objects communicate using signals and slots. Whenever a widget changes state, or an event occurs, a signal is emitted. This signal has a pre-defined signature, and if another object wants to receive this signal it must define a slot with the same signature.
• Qt’s widgets have many pre-defined slots, but it is common practice to subclass widgets and add your own slots so that you can handle the signals that you are interested in. The signals and slots mechanism is type safe: The signature of a signal must match the signature of the receiving slot.

I have a QTextEdit box that displays text, and I'd like to be able to set the text color for different lines of text in the same QTextEdit box. (i.e. line 1 might be red, line 2 might be black, etc.)

Is this possible in a QTextEdit box? If not, what's the easiest way to get this behavior?

Thanks.

Use text formated as HTML, for example:

where text, is a HTML formated text, contains with colored lines and etc.

(i.e. line 1 might be red, Just a quick addition: an alternative to generating the html yourself, if you're populating the text box programatically, is to use textEdit->setTextColor(QColor&). You can create the QColor object yourself, or use one of the predefined colours in the Qt namespace (Qt::black, Qt::red, etc).

The ONLY thing that worked for me was html.

It will apply the specified colour to any text you add, until it is called again with a different one.

multicolor text in QPlainTextEdit, Hello, I'm looking for a solution to append single characters to QTextEdit with different colors. I tried the following: QTextCursor j'ai un QTextEdit boîte qui affiche le texte, et j'aimerais pouvoir définir la couleur du texte pour différentes lignes de texte dans le même QTextEdit boîte. (c.-à-d. que la ligne 1 peut être rouge, la ligne 2 peut être noire, etc.)

A few quotes:

QTextEdit is an advanced WYSIWYG viewer/editor supporting rich text formatting using HTML-style tags. It is optimized to handle large documents and to respond quickly to user input.

.

The text edit can load both plain text and HTML files (a subset of HTML 3.2 and 4).

QTextEdit can display a large HTML subset, including tables and images.

This means mostly deprecated tags and as such does not include any current CSS, so I turned to this:

QTextEdit::append() inserts a new paragraph with the previously set FontWeight / TextColor.insertHTML() or InsertPlainText() to avoid inserting a new paragraph (e.g. to achieve different formats in a single line) do not respect the font/color settings.

Instead use QTextCursor:

• This is by far the simplest solution to do so. Works like a charm for example for logging, where each line is colored according to the message's severity.
• but this only colors all the text present , i want to color each color with a diff color , can u please help me with that ?
• If you are using a 'textEdit' object, it will color the text of each 'append' call with a different color.
• this answer taught me new things
• This wound up working for me. One line is one color, and the next line is a different color. In this example, after 'Hello World', you would put lines format.setForeground( QBrush( QColor( 'white' ) ) ); and cursor.setCharFormat( format ); and cursor.insertText( 'This line is white' );.
• The problem is that original text colour is theme-dependent and may be anything, not only black.
