Recently, some people asked how to use qt4 to set the font color in the qlabel.

In fact, this is a common problem. There are several methods: setpalette (), style sheet, qstyle, and simple HTML styles. The following is a summary.


First, use setpalette () as follows:



Qlabel * label = new qlabel (TR ("Hello QT! "));

Qpalette PE;

PE. setcolor (qpalette: windowtext, QT: White );

Label-> setpalette (PE );

Qpalete: window, usually the background color of the window part;

Qpalette: windowtext, which usually refers to the foreground view without a window;

Qpalette: base indicates the background color of text input window components (such as qtextedit and qlinedit.

Qpalette: Text, used together with qpalette: Base, refers to the foreground color of the text input window part;

Qpalette: button, which indicates the background color of the Button widget;

Qpalette: buttontext, which refers to the foreground color of the Button widget.

Second, use the style sheet as follows:


Setstylesheet (font-color: Your color );


// For more information, see QT assistant.


Third, the use of qstyle has a good example of qstyle in QT demo. For more information, see.


Fourth, some simple HTML formats are used:


Qlabel * label = new qlabel (TR ("Hello QT! "));

Qlabel * label = new qlabel ("<H2> <I> Hello </I> <font color = Red> QT! </Font> </H2> ");
