前言

熟悉QTableWiget，通過實現單元格的合并、拆分、通過編輯界面實現表格內容及屬性的配置、實現表格的粘貼復制功能熟悉QTableWiget的屬性

一、單元格的合并、拆分

二、表格內容及屬性設置

1.效果圖

通過雙擊單元格進入編輯界面

2.主要代碼

編輯界面的代碼如下：

void CItemTypeDialog::init()
{m_bold = 0;m_pFontColorDlg = new  QColorDialog(this);mp_bgdColorDialog = new  QColorDialog(this);connect(m_pUi->pButtonOk,SIGNAL(clicked()),this,SLOT(onOk()));connect(m_pUi->pButtonCancel,SIGNAL(clicked()),this,SLOT(onCancel()));connect(m_pUi->pFontColorBtn, &QPushButton::clicked, this, &CItemTypeDialog::showColorDialog);connect(m_pUi->pBackgroundBtn, &QPushButton::clicked, this, &CItemTypeDialog::showColorDialog);connect(m_pFontColorDlg, &QColorDialog::currentColorChanged, this, &CItemTypeDialog::colorValue);connect(mp_bgdColorDialog, &QColorDialog::currentColorChanged, this, &CItemTypeDialog::bgdcolorValue);sprintf(m_bgdcolorarr, "#%s%s%s","ff","ff","ff");sprintf(m_fontcolorarr, "#%s%s%s","00","00","00");
}void CItemTypeDialog::setType(TableItemInfor *pItem)
{m_pItem = pItem;m_pUi->textEdit->setText(m_pItem->data);QString str = QString::fromUtf8(m_pItem->style);if (!(str.isEmpty())){QStringList stylelist = str.split(",");m_pUi->pFontComboBox->setCurrentText(stylelist.at(0));//字體m_pUi->pFontSizeComboBox->setCurrentText(stylelist.at(1));//字號//是否加粗m_pUi->boldCheckBox->setChecked(stylelist.at(2).toInt());//字體顏色strcpy(m_fontcolorarr, stylelist.at(3).toUtf8());m_pUi->pFontColorBtn->setStyleSheet(QString::fromUtf8("background-color: %1;").arg(stylelist.at(3)));QColor color(stylelist.at(3));m_pFontColorDlg->setCurrentColor(color);//背景顏色strcpy(m_bgdcolorarr, stylelist.at(4).toUtf8());m_pUi->pBackgroundBtn->setStyleSheet(QString::fromUtf8("background-color: %1;").arg(stylelist.at(4)));QColor bgcolor(stylelist.at(4));mp_bgdColorDialog->setCurrentColor(bgcolor);}}
void CItemTypeDialog::showColorDialog()
{QToolButton* tb = qobject_cast<QToolButton*>(sender());if (tb == m_pUi->pFontColorBtn){m_pFontColorDlg->show();}else if (tb == m_pUi->pBackgroundBtn){mp_bgdColorDialog->show();}
}
void CItemTypeDialog::onOk()
{getStyle();accept();
}void CItemTypeDialog::onCancel()
{reject();
}void CItemTypeDialog::getStyle()
{m_pItem->data = m_pUi->textEdit->toPlainText();sprintf(m_pItem->style, "%s,%d,%d,%s,%s", m_pUi->pFontComboBox->currentText().toStdString().c_str(),m_pUi->pFontSizeComboBox->currentText().toInt(), m_bold, m_fontcolorarr, m_bgdcolorarr);
}void CItemTypeDialog::colorValue(const QColor& color)
{int r, g, b, a;color.getRgb(&r, &g, &b, &a);QString hexRed = QString::number(r, 16);if (hexRed == "0"){hexRed = "00";}QString hexGreen = QString::number(g, 16);if (hexGreen == "0"){hexGreen = "00";}QString hexBlue = QString::number(b, 16);if (hexBlue == "0"){hexBlue = "00";}sprintf(m_fontcolorarr, "#%s%s%s", hexRed.toStdString().c_str(), hexGreen.toStdString().c_str(), hexBlue.toStdString().c_str());m_pUi->pFontColorBtn->setStyleSheet(QString::fromUtf8("background-color: %1;").arg(QString::fromUtf8(m_fontcolorarr)));
}void CItemTypeDialog::bgdcolorValue(const QColor &color)
{int r, g, b, a;color.getRgb(&r, &g, &b, &a);QString hexRed = QString::number(r, 16);if (hexRed == "0"){hexRed = "00";}QString hexGreen = QString::number(g, 16);if (hexGreen == "0"){hexGreen = "00";}QString hexBlue = QString::number(b, 16);if (hexBlue == "0"){hexBlue = "00";}sprintf(m_bgdcolorarr, "#%s%s%s", hexRed.toStdString().c_str(), hexGreen.toStdString().c_str(), hexBlue.toStdString().c_str());m_pUi->pBackgroundBtn->setStyleSheet(QString::fromUtf8("background-color: %1;").arg(QString::fromUtf8(m_bgdcolorarr)));
}

三、表格的粘貼復制功能

功能待完善！
