У меня есть страница мастера, как показано ниже -
Когда нажата кнопка Next, панель прогесов отображается, как показано ниже -
Если действие панели Progess отменено, я хочу сохранить пользователя на той же странице, откуда нажимается следующая кнопка. Как я могу добиться этого?
Я делаю ниже, чтобы показать индикатор выполнения WizardPage2
@Override
public void setVisible(boolean visible) {
if (visible) {
InterfacePage interfacePage = (InterfacePage) (getWizard().getPage("NewInterfacePage"));
String interfaceId = interfacePage.getInterfaceID();
try {
getContainer().run(true, true, new IRunnableWithProgress() {
@Override
public void run(IProgressMonitor arg0) throws InvocationTargetException, InterruptedException {
int amount = 10;
arg0.beginTask("Fetching details from External System...", 10);
for (int i = 0; i < amount; i++) {
arg0.internalWorked(1);
Thread.sleep(2000);
if (arg0.isCanceled()) {
cancelled = true;
break;
}
}
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
super.setVisible(visible);
}
Пример кода, который не работает -
