Overview

The QFontComboBox widget is a combobox that lets the user select a font family.

The combobox is populated with an alphabetized list of font family names, such as Arial, Helvetica, and Times New Roman. Family names are displayed using the actual font when possible.

For fonts such as Symbol, where the name is not representable in the font itself, a sample of the font is displayed next to the family name.


Various function

  • This property holds the filter for the combobox.
QFontComboBox *font=new QFontComboBox();
font->setFontFilter(QFontComboBox::NonScalableFonts);
  • This property holds the writing system that serves as a filter for the combobox.
font->setWritingSystem(QFontDatabase::Thaana);

Signal and Slots

QObject::connect(font,SIGNAL(currentFontChanged(QFont)),edit,SLOT(setCurrentFont(QFont)));
