如何使用 QTable？添加、编辑、删除和检索行

发布于 2024-10-07 18:25:36 字数 329 浏览 4 评论 0原文

如何使用 QTable 对象。我在网上搜索过，这些例子似乎并没有什么意义。您是否只是在扩展类中创建一个新行。一切看起来都很热闹。如何检索、编辑和删除行。是否有任何可以使用的扩展，例如

QRowObject *row = table->add("Main Title");
row->addSubColumnText("Second column");
otherRow = table->getRowByIndex(table->selectedIndex);
otherRow.remove;

如何实现它？

需要任何额外信息只需询问。

How do you use the QTable object. I have searched the internet and the examples don't really seem to make sense. Do you just create a new row within the extended class. It all seems fussing. How do you retreive, edit and delete rows. Is there any extensions that could be used like

QRowObject *row = table->add("Main Title");
row->addSubColumnText("Second column");
otherRow = table->getRowByIndex(table->selectedIndex);
otherRow.remove;

How would any implement that?

Any extra information needed just ask.

QTable 已经很老了。您可能正在寻找QTableWidget。如果您想了解整个“模型视图”架构，请查看 QTableView 。

// inside e.g. a QMainWindow, parent could be 'this'
QTableWidget *widget = new QTableWidget(parent); 
// add to layout etc, then:

QStringList headerLabels;
headerLabels << "First Column" << "Second Column";
widget->setHorizontalHeaderLabels(headerLabels);
// here you would add data, then:
widget->removeRow(table->currentRow());

QTable is pretty old. You might be looking for QTableWidget. If you want to get into the whole 'Model-View' arch thing, look into QTableView.

// inside e.g. a QMainWindow, parent could be 'this'
QTableWidget *widget = new QTableWidget(parent); 
// add to layout etc, then:

QStringList headerLabels;
headerLabels << "First Column" << "Second Column";
widget->setHorizontalHeaderLabels(headerLabels);
// here you would add data, then:
widget->removeRow(table->currentRow());
