Question

我想在我点击QTableWidget（tblbimar）中的select botton时给我相同的行数（QTable）。但是，当我点击“选择”按钮时，没有任何事情发生！当然我试过是否发送信号“tbl_bimar_row”？（它工作正常）

我将以上代码更改为以下代码并且有效：

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)

获取pyqt中qtablewidget的行数
