setWindowFlag(Qt::NoDropShadowWindowHint);
setObjectName("test");
setStyleSheet(OVERALL_TOOL->loadqss("menu_def.qss"));
win = new QWidget (this);
QLineEdit * ple_edit = new QLineEdit(win);
ple_edit->setGeometry(0,0,150,30);

win->setStyleSheet("QWidget{background:rgba(255,255,255,255);}");
QVBoxLayout * lay = new QVBoxLayout ;lay->setMargin(5);lay->setSpacing(0);
setLayout(lay);
lay->addWidget(win);
