Qt button

在这里插入代码#include "text_1.h"
#include <qvariant.h>
#include <QDebug>
#include<qbuttongroup.h>
text_1::text_1(QWidget *parent)
	: QMainWindow(parent)
{
	ui.setupUi(this);	 
	 btnGroup = new QButtonGroup(this);

	connect(btnGroup, qOverload<int>(&QButtonGroup::buttonPressed), this, [this](int id_) {
		id = id_;
		qDebug() << "btn: " << id << " clicked";
	});
	for(int k=1;k<3;k++)
	{ 
	for (int i = 1; i < 6; i++) 
	{
		pbt_seat = new QPushButton(this);
		pbt_seat->setCheckable(true);
		pbt_seat->setProperty("id",QVariant(i * k));
		pbt_seat->setText(QString("%1").arg(i));
		pbt_seat->setFixedSize(50, 50);
		pbt_seat->move(k * 100 + 50, i*50+50);
		btnGroup->addButton(pbt_seat,k*i);
		
	}
	}

	connect(ui.pbt_send, &QAbstractButton::clicked, [this] {
		auto btn = btnGroup->button(id);
		qDebug() << btn;
		qDebug() <<id <<" "<<ui.textEdit->document()->toPlainText();
	});
}
