Question

我试图将项目添加到动态创建的组合框中。我知道我的变量会超越自己，我无法获得理想的结果。 Combobox操作将项目添加到我不想要的最后一个项目。它需要在下一个项目中添加项目。

@Before
public void start(Scenario scenario) throws Exception {
    logger.logTestEnd(String.format("Scenario '%s' start", scenario.getName()));
    ...
}

@After
public void exitScenario(Scenario scenario) throws Exception {
    if (scenario.isFailed()) {
        Screenshot.saveScreenshotInReport(scenario, BrowserManager.getDriver());
        logger.info(String.format("scenario[%s] is failed", scenario.getName()));
    }
    BrowserManager.quit();
    logger.logTestEnd(String.format("Scenario '%s' end", scenario.getName()));
}

我想我需要一些改变。我尝试设置对象名，并以某种方式连接组合框，但我没有。

我解决了这个问题。找到ObjectName和findChild的使用并进行一些更改.Voila！

这是解决方案。

    def addItem(self, text):
    sendin  = self.centralwidget.sender()
    objname = str(sendin.objectName())
    objnamevalue =  objname.split('_')[1]
    self.centralwidget.findChild(QtGui.QComboBox, 'ScomboBox_' + objnamevalue).addItem(text)
