Pyqt 获取动态生成的QLineEdit值

动态生成控件参考上一篇： http://www.cnblogs.com/dcb3688/p/4588814.html

 

那如何获取动态生成控件的值呢？

比如，动态的生成10个输入框QLineEdit，输入值后，要获取每一个LineEdit的值。 在这里我们通过字典dict{} 来存储控件，循环dict 获取控件的text()

class MainWidget(QDialog):

    def __init__(self, parent=None):

        super(MainWidget, self).__init__(parent)

        self.setMinimumSize(100, 100)

        self.setWindowFlags(Qt.CustomizeWindowHint|Qt.WindowCloseButtonHint)

        self.setWindowOpacity(0.9)



        # 添加头部group

        self.headDict = {}

        self.headPostArrayKey = 0

        self.HeadGroupBox = QGroupBox(u'动态添加控件数据')

        self.HeadGroupBox.setMinimumHeight(100)  #高度最小值

        self.HeadGroupBox.scroll(100,2)

        self.HeadAddParam = QPushButton(u'+')

        self.headDict[str(self.headPostArrayKey)+'_key'] = QLineEdit()

        self.headDict[str(self.headPostArrayKey)+'_value'] = QLineEdit()

        self.HeadGroupBoxLayout = QGridLayout()

        self.HeadGroupBoxLayout.addWidget(self.HeadAddParam, 0, 0)

        self.HeadGroupBoxLayout.addWidget(QLabel(u'Key：'), 1, 0)

        self.HeadGroupBoxLayout.addWidget(self.headDict[str(self.headPostArrayKey)+'_key'], 1, 1)

        self.HeadGroupBoxLayout.addWidget(QLabel(u'Value：'), 1, 2)

        self.HeadGroupBoxLayout.addWidget(self.headDict[str(self.headPostArrayKey)+'_value'], 1, 3)

        self.HeadGroupBox.setLayout(self.HeadGroupBoxLayout)

        self.HeadAddParam.clicked.connect(self.addHeadParam)





        # 提交按钮

        self.btnPost = QPushButton(u'提交')

        self.postbtnLoayout = QHBoxLayout()

        self.postbtnLoayout.addStretch()

        self.postbtnLoayout.addWidget(self.btnPost)

        # Main布局

        main_layout = QVBoxLayout()

        main_layout.addWidget(self.HeadGroupBox)

        main_layout.addLayout(self.postbtnLoayout)  # addLayout 添加的是 Layout

        main_layout.setSpacing(0)

        self.setLayout(main_layout)



        self.connect(self.btnPost, SIGNAL('clicked()'), self.postData)





    def postData(self):

        self.headdictdata={}

        for k, v in self.headDict.items():

            temp=k.split('_')

            if temp[1]=='key':

                if self.headdictdata.has_key(temp[0]):

                    self.headdictdata[temp[0]]['key'] =str(v.text())

                else:

                    self.headdictdata[temp[0]] = {'key':str(v.text())}



            elif temp[1]=='value':

                if self.headdictdata.has_key(temp[0]):

                    self.headdictdata[temp[0]]['value'] =str(v.text())

                else:

                    self.headdictdata[temp[0]] = {'value':str(v.text())}



        print(self.headdictdata)



    # 添加头部Data

    def addHeadParam(self):

        sts=str(self.headPostArrayKey+1)

        self.headDict[sts+'_key'] = QLineEdit(sts+'name')

        self.headDict[sts+'_value'] = QLineEdit(sts+'chrome')



        self.HeadGroupBoxLayout.addWidget(QLabel(u'Key'))

        self.HeadGroupBoxLayout.addWidget(self.headDict[sts+'_key'])

        self.HeadGroupBoxLayout.addWidget(QLabel(u'Value'))

        self.HeadGroupBoxLayout.addWidget(self.headDict[sts+'_value'])

        self.headPostArrayKey+=1







if __name__ == "__main__":

    import sys

    app = QApplication(sys.argv) 

    main_widget = MainWidget()

    main_widget.show()

    sys.exit(app.exec_())

 

效果：

打印数据：

{'1': {'value': '1chrome', 'key': '1name'}, '0': {'key': 'keyname', 'value': 'htmls'}, '3': {'value': '3chrome', 'key': '3name'}, '2': {'value': '2chrome', 'key': '2name'}}
