我使用for(int i = 0; i 赞: 当我更改组合框或百分比值时。最后,我要获取百分比和comboBox值。
像这样: QString Runner1 = QString(_Numberlabel-> text()+ label-> text()+ lineEdit-> text()+ comboBox-> currentText());
QString Runner2 = QString(_Numberlabel-> text()+ label-> text()+ lineEdit-> text()+ comboBox-> currentText()); i=0 1.Runner distance ,percentage = %80 Place = ComboBoxValue
i=1 1.Runner distance ,percentage = %60 Place = ComboBoxValue
enter code here
for(int i=0; i < runnerList.size() ;i++)
{
Layout = new QHBoxLayout();
Layout->setSpacing(6);
_Numberlabel= new QLabel();
_Numberlabel->setObjectName(QString::fromUtf8("_Numberlabel"));
_Numberlabel->setText(QString("First Runner").arg(i+1).arg(runnerList[i][0]).arg(runnerList[i][1]));
QFont font;
font.setFamily(QString::fromUtf8("Calibri"));
font.setPointSize(10);
font.setBold(true);
font.setWeight(75);
_Numberlabel->setFont(font);
Layout->addWidget(_Numberlabel);
label = new QLabel();
label->setObjectName(QString::fromUtf8("label"));
label->setMaximumSize(QSize(60, 16777215));
label->setFont(font);
label->setText("Percantage:");
Layout->addWidget(label);
lineEdit = new QLineEdit();
lineEdit->setObjectName(QString::fromUtf8("lineEdit"));
lineEdit->setMaximumSize(QSize(50, 16777215));
lineEdit->setText("%");
Layout->addWidget(lineEdit);
comboBox = new QComboBox();
comboBox->setObjectName(QString::fromUtf8("comboBox"));
comboBox->setMinimumSize(QSize(0, 25));
comboBox->setMaximumSize(QSize(90, 16777215));
comboBox->addItem("1");
comboBox->addItem("2");
comboBox->addItem("3");
comboBox->addItem("4");
Layout->addWidget(comboBox);
this->ui.verticalLayout->addLayout(Layout);
}
答案 0 :(得分:0)
您任何一个都需要保留创建的对象的句柄:
// definition:
QList<QLineEdit*> lineEdits;
QList<QComboBox*> combos;
这些列表应该是班级成员。
// usage:
for(int i=0; i < runnerList.size() ;i++)
{
//...
lineEdits << lineEdit;
combos << comboBox;
}
然后,您可以稍后获取这些值:
... = QString(lineEdits[i]->text() + combos[i]->currentText());
或者,您可以通过其唯一的对象名称找到它们:
ui.verticalLayout->findChild<QLineEdit*>(QString("lineEdit_%1").arg(i))->text();
// I didn't try to compile this code!
为此,您需要为每个QLineEdit
/ QComboBox
指定一个唯一的对象名称。
或者,您搜索所有QLineEdit
,并希望它们的顺序定义明确:
ui.verticalLayout->findChildren<QLineEdit*>("lineEdit")[i]->text();
免责声明:这非常丑陋,但是您应该能够看到它的工作原理。
无论您选择什么,都要注意:
您的行
_Numberlabel->setText(QString("First Runner").arg(i+1).arg(runnerList[i][0]).arg(runnerList[i][1]));
包含错误,因为您的QString(...)
不包含占位符%1
,%2
,...,但后面跟随着.arg()
调用。除了在控制台上创建警告之外,它什么也不会做。
