void occQt::about2() //UI
{
QWidget* pWidget = new QWidget;
QLabel* longlabel = new QLabel(tr("long"));
QLabel* widthlabel = new QLabel(tr("width"));
QLabel* highlabel = new QLabel(tr("high"));
longlineedit = new QLineEdit;
widthlineedit = new QLineEdit;
highlineedit = new QLineEdit;

longlineedit->setText("5");
widthlineedit->setText("5");
highlineedit->setText("5");
btnlayout->setSpacing(60);
btnlayout->addWidget(okbtn);
btnlayout->addWidget(cancelbtn);
//pWidget->setLayout(gridlayout);
dlglayout->setMargin(50);
dlglayout->addLayout(gridlayout);
dlglayout->addStretch(40);
dlglayout->addLayout(btnlayout);
pWidget->setLayout(dlglayout);
pWidget->setWindowTitle(tr("Make a Box by custom."));
pWidget->show();
connect(okbtn, SIGNAL(clicked()), pWidget, SLOT(makeyourbox()));
//QObject::connect(okbtn, SIGNAL(clicked()), pWidget, SLOT(close()));
connect(cancelbtn, SIGNAL(clicked()), pWidget, SLOT(close()));
}
void occQt::makeyourbox()
{
QString string_a = longlineedit->text();
eason_a = string_a.toInt();
QString string_b = widthlineedit->text();
eason_b = string_b.toInt();
QString string_c = highlineedit->text();
eason_c = string_c.toInt();
TopoDS_Shape aTopoBox = BRepPrimAPI_MakeBox(eason_a, eason_b, eason_c).Shape();
Handle_AIS_Shape anAisBox = new AIS_Shape(aTopoBox);
anAisBox->SetColor(Quantity_NOC_AZURE);
mContext->Display(anAisBox);
}
When I run the pWidget, click cancelbtn, ui close. 当我运行pWidget时,单击cancelbtn,ui关闭。 Click okbtn,do nothing.. 单击确定,不执行任何操作。
pWidget is a generic QWidget. pWidget是通用的QWidget。 It does not contain method/slot makeyourbox(). 它不包含方法/插槽makeyourbox()。 Your code is faulty. 您的代码有误。
您应该将makeyourbox()
方法添加到QWidget
的子类中,并将其标记为slot
仔细检查makeyourbox
定义为该类中的一个插槽。
