获取pyqt中qtablewidget的行数答案

【问题标题】：obtain the number of rows of qtablewidget in pyqt获取pyqt中qtablewidget的行数

【问题描述】：

当我单击 QTableWidget(tblbimar) 中的选择按钮时，我希望给我相同的行数(QTable)。但是当我点击“选择”按钮时，什么也没有发生！
当然我试过是否发送信号“tbl_bimar_row”，（它工作正常）

class groupbutton(QWidget):
    tbl_bimar_row = pyqtSignal(int)
    def __init__(self,parent=None):
        super(groupbutton,self).__init__(parent)
        self.parent = parent

    def return_row(self):
        widget_pos = QtGui.qApp.focusWidget()
        index = self.parent.indexAt(widget_pos.parentWidget().pos())

        if index.isValid():
            self.tbl_bimar_row.emit(index.row())

            self.tblbimar.setItem(inx,4,QTableWidgetItem(row[4]))
            selbtn = groupbutton(parent=self.tblbimar)
            selbtn.tbl_bimar_row.connect(self.bimar_select)
            self.tblbimar.setCellWidget(inx,5,selbtn)
            # self.tblbimar.setItem(inx,5,QTableWidgetItem(smart_text(row[0])))
            self.tblbimar.resizeColumnsToContents()
            self.tblbimar.resizeRowsToContents()

谢谢

当我使用 QMainWindow 它工作但如果我使用 QDialog 不起作用！？

【解决方案1】：

我将上面的代码改成如下，它工作了：

class groupbutton(QWidget):
    tbl_bimar_row = pyqtSignal(int)
    def __init__(self,parent=None,app=None):
        super(tblbutton,self).__init__(parent)

        self.parent = parent
        self.app = app  
        ...
        ...
    def return_row(self):
        widget_pos = self.app.focusWidget()
        index = self.parent.indexAt(widget_pos.parentWidget().pos())
        self.tbl_bimar_row.emit(index.row())
class Jarahi_add(QDialog,Ui_My_Form):
    ...  
    ... 
    def get_bimar(self):

        if data:
            for row in data:
                ...  
                ...  
                selbtn = tblbutton(parent=self.tblbimar,app=self)
                selbtn.tbl_bimar_row.connect(self.bimar_select)
                self.tblbimar.setCellWidget(inx,5,selbtn)
