PyQt5中QButton例子

'''

import sys

from PyQt5.QtCore import *

from PyQt5.QtGui import *

from PyQt5.QtWidgets import *

class Form(QDialog):

def init (self, parent=None):

super(Form, self). init (parent)

layout = QVBoxLayout()

if name == ' main ':

app = QApplication(sys.argv)

btnDemo = Form()

btnDemo.show()

sys.exit(app.exec_())

1 定义一个按钮

QPushButton * pBtn = new QPushButton()

2 链接信号与曹

connect(pBtn, SIGNAL(clicked()), this, SLOT(OnBtnClicked()))

3 按钮添加到单元格内

table->setCellWidget(0,0,pBtn)//如果点击按钮出现崩溃现象，就添加QTableWidgetItem 到按钮的那个单元格

4 实现按钮的事件

void myPic::OnBtnClicked(void) { QPushButton * senderObj=qobject_cast<QPushButton *>(sender()) if(senderObj == 0) { return } QModelIndex index =table->indexAt(QPoint(senderObj->frameGeometry().x(),senderObj->frameGeometry().y())) int row=index.row() qDebug()<<"row:"<<row}
