main.cpp -
#include"ptedit_1.h"
#include"kcheckcombobox.h"

intmain(intargc,char*argv[])
{
QApplicationapp(argc,argv);
QWidget*widget=newQWidget;
UI::pteditui;//this statement is giving syntactical error, I tried to write it write class Ui_MainWindow but in vain.
ui.setupUi(widget);
widget->show();
returnapp.exec();
}
I tried to include ui_ptedit.h but it is giving more errors ,Please have a look.
