[Android] qt part of the text can not be achieved in a dynamic language switching

In his qt project has both English and Chinese languages ​​can be switched at any time , but now found that some text can not be switched into Chinese . For example, the following code :
MainWindow :: MainWindow (QWidget * parent):
QMainWindow (parent),
ui (new Ui :: MainWindow)
{
ui-> setupUi (this);

QTranslator trans;
trans.load ("gui_zh");
QApplication :: installTranslator (& trans);
ui-> retranslateUi (this);
}

MainWindow :: ~ MainWindow ()
{
delete ui;
}

void MainWindow :: on_pushButton_clicked ()
{
QString fileName = QFileDialog :: getOpenFileName (this, tr ("open"), QDir :: currentPath (), "* . cpp ");
}

The red part is to open a dialog box to get the path to a file , "open" is how the string are not a Chinese translation , such examples in my project there are many, who can tell me this is how things , there is no solution ?
Note: I have generated the specified qm file
------ Solution -------------------------. -------------------
first you write or translate a document class file must have Q_OBJECT, first make sure your *. qm files which are English translation of all the best to your translation files (*. qm) joined the program resource file , and then add in the main program
QTranslator * translator = new QTranslator (0);
translator-> load (":/ * qm.");
QApplication object using the call app
app.installTranslator (translator);
I hope to help you
------ Solution ------------------------------- -------------

their first top

your question is not very clear .
first load did not translate ? After the switch is in English, the switch did not translate over time ?
I feel the possibility of a second relatively large .

when switching languages. Sends LanguageChange events.
generally when handling this event . ui-> retranslateUi (this); Ui interface will be re- translated.
but tr function inside part of the program before you call may fail .
You have to re-set inside LanguageChange events.

class there Q_OBJECT, after running the software will load the translation file , then the translation part is normal, but for example, the code inside the red phrase "open" string was not a Chinese translation , not what you say second , re-set in which you say LanguageChange event , which function in this what you want to set , how to set up , please let us know !
------ eference --------------------------------------- < br> you this question , really did not come across. Are you sure you qm translation ?
You can try to print QApplication :: translate ("MainWindow", "open", 0, QApplication :: UnicodeUTF8)
look is not Chinese ?
if not Chinese . Qm explain your problem , there is no translation .

or not, do not know if my computer problems, try to go home with a laptop , you do not come across this question, in my project this problem many ah
------ eference - --------------------------------------
if QApplication :: translate (" ; MainWindow "," open ", 0, QApplication :: UnicodeUTF8) this is the English words.
That is your translation problem.
look ts and qm it.
