QTableView修改单元格颜色及禁止单元格数据编辑

1.添加数据

void Reader::AddTableView(QTableView* tv, QMap<QString, QString> mData)
{
	QStandardItemModel* model = new QStandardItemModel();
	model->setColumnCount(2);
	model->setHeaderData(0, Qt::Horizontal, QString::fromLocal8Bit("Addr"));
	model->setHeaderData(1, Qt::Horizontal, QString::fromLocal8Bit("Value"));
	model->setRowCount(mData.size());
	for (int i = 0; i < mData.size(); i++)
	{
		model->setHeaderData(i, Qt::Vertical, i + 1);
	}
	QMap<QString, QString>::iterator it = mData.begin();
	for (int i = 0; it != mData.end(); it++, i++)
	{
		model->setItem(i, 0, new QStandardItem(it.key()));
		model->setItem(i, 1, new QStandardItem(it.value()));
	}
	tv->setModel(model);
}

2.设置背景颜色

QModelIndex jcIndex = tv->model()->index(i, j);
tv->model()->setData(jcIndex, QBrush(Qt::red), Qt::BackgroundRole);

3.禁止编辑

//tableview整体禁止编辑
tv->setEditTriggers(QAbstractItemView::NoEditTriggers);

4.自定义编辑

#pragma once

#include <QItemDelegate> 
#include <QWidget> 

class QTableReadOnlyDelegate : public QItemDelegate
{
	
//委托
public:
	QTableReadOnlyDelegate(QWidget* parent = NULL) : QItemDelegate(parent)
    {
    }

    QWidget* createEditor(QWidget* parent, const QStyleOptionViewItem& option,
        const QModelIndex& index) const override //final
    {
        Q_UNUSED(parent)
        Q_UNUSED(option)
        Q_UNUSED(index)
        return NULL;
    }
};

#include "QTableViewTest.h"
#include "qtablereadonlydelegate.h"
#include <qstandarditemmodel.h>

QTableViewTest::QTableViewTest(QWidget *parent)
    : QMainWindow(parent)
{
    ui.setupUi(this);
	MemberInit();
	WidgetInit();
}

void QTableViewTest::MemberInit()
{

}

void QTableViewTest::WidgetInit()
{
    QTableReadOnlyDelegate* tableDelegate = new QTableReadOnlyDelegate();
    ui.tableView->setItemDelegateForColumn(0, tableDelegate);
    ui.tableView->setItemDelegateForRow(0, tableDelegate);

	QStandardItemModel* model = new QStandardItemModel();
	model->setColumnCount(2);
	model->setHeaderData(0, Qt::Horizontal, QString::fromLocal8Bit("Addr"));
	model->setHeaderData(1, Qt::Horizontal, QString::fromLocal8Bit("Value"));
	QMap<QString, QString> mData;
	mData.insert("0x11", "66");
	mData.insert("0x22", "77");
	model->setRowCount(mData.size());
	for (int i = 0; i < mData.size(); i++)
	{
		model->setHeaderData(i, Qt::Vertical, i + 1);
	}
	QMap<QString, QString>::iterator it = mData.begin();
	for (int i = 0; it != mData.end(); it++, i++)
	{
		model->setItem(i, 0, new QStandardItem(it.key()));
		model->setItem(i, 1, new QStandardItem(it.value()));
	}
	ui.tableView->setModel(model);
}
