QT中qsqltablemodel类怎么设置居中显示

Answer 1

用qsqltablemodel的insetrow()、setdata()、submitall（）函数实现增；　　&nbsp;officeTable->insertRow(0);　　&nbsp;officeTable->setData(officeTable->index(0,&nbsp;0),&nbsp;row);　　&nbsp;officeTable->setData(officeTable->index(0,&nbsp;1),&nbsp;newWnd->imageFileEditor->currentIndex());　　&nbsp;officeTable->setData(officeTable->index(0,&nbsp;2),&nbsp;newWnd->locationText->text());　　&nbsp;officeTable->setData(officeTable->index(0,&nbsp;3),&nbsp;newWnd->countryText->currentText());　　&nbsp;officeTable->setData(officeTable->index(0,&nbsp;4),&nbsp;newWnd->descriptionEditor->toPlainText());　　&nbsp;officeTable->submitAll();&nbsp;用removerow()、submitall（）函数实现删；　　&nbsp;int&nbsp;officeCount&nbsp;=&nbsp;officeTable->rowCount();　　&nbsp;officeTable->removeRow(id);　　&nbsp;for(int&nbsp;i&nbsp;=&nbsp;id;&nbsp;i&nbsp;<&nbsp;officeCount&nbsp;-&nbsp;1;i++)　　&nbsp;{　　&nbsp; officeTable->setData(officeTable->index(i,&nbsp;0),&nbsp;i);　　&nbsp;}　　&nbsp;officeTable->submitAll();用QSqlRecord类的setvalue实现改；　　&nbsp; QSqlRecord&nbsp;recordCurrentRow&nbsp;=&nbsp;officeTable->record(id);　　&nbsp; recordCurrentRow.setValue("id",&nbsp;id&nbsp;-&nbsp;1);　　&nbsp; officeTable->setRecord(id&nbsp;-&nbsp;1,&nbsp;recordCurrentRow);　　&nbsp; officeTable->submitAll();&nbsp;用QSqlRecord类的.value进行比较实现查；　　int&nbsp;Dialog::findArtistId(const&nbsp;QString&nbsp;&artist)　　{　　&nbsp; &nbsp; QSqlTableModel&nbsp;*artistModel&nbsp;=&nbsp;model->relationModel(2);&nbsp; &nbsp; int&nbsp;row&nbsp;=&nbsp;0;&nbsp;　　&nbsp; &nbsp; while&nbsp;(row&nbsp;<&nbsp;artistModel->rowCount())&nbsp;{　　&nbsp; &nbsp; &nbsp; &nbsp; QSqlRecord&nbsp;record&nbsp;=&nbsp;artistModel->record(row);　　&nbsp; &nbsp; &nbsp; &nbsp; if&nbsp;(record.value("artist")&nbsp;==&nbsp;artist)　　&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return&nbsp;record.value("id").toInt();　　&nbsp; &nbsp; &nbsp; &nbsp; else　　&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; row++;　　&nbsp; &nbsp; }　　&nbsp; &nbsp; return&nbsp;addNewArtist(artist);}&nbsp;
