Controls are also provided to enable users to choose from the printers available, including any configured network printers. Typically, QPrintDialog objects are constructed with a QPrinter object, and executed using the exec() function. \snippet doc/src/snippets/code/src_gui_dialogs_qabstractprintdialog.cpp 0 If the dialog is accepted by the user, the QPrinter object is correctly configured for printing. \raw HTML
