Sample program hellotr.pro cannot build and run. Why? (Solved)

houmingc

I could not build the sample program(hellotr.pro) in Qt5.3.1.
Please kindly advice. Very difficult for a newie to see the error.
The examples is in /home/common/Qt5.3.1/Examples

@
===hellotr.pro==========================================
SOURCES = main.cpp
TRANSLATIONS = hellotr_la.ts

target.path = /home/common/Qt5.3.1/Examples/Qt-5.3/linguist/hellotr
INSTALLS += target sources

QT += widgets
#simulator: warning(This example might not fully work on Simulator platform)
@

@
===main.cpp================================================
#include <QApplication>
#include <QPushButton>
#include <QTranslator>

int main(int argc, char *argv[])

{
QApplication app(argc, argv);
QTranslator translator;

translator.load("hellotr_la");
app.installTranslator(&translator);
QPushButton hello(QPushButton::tr("Hello world!"));
hello.resize(100, 30);
hello.show();
return app.exec(&#41;;

}

under linguist examples, i cannot set the hello world to thai language

houmingc

i am following the link below
http://qt.developpez.com/doc/4.7/linguist-hellotr/

Do i have to do the translation myself, i thought it is done automatically?

1.in linguist/hellotr, initially there is only two file
hellotr.pro & main.cpp

2.after running "lupdate -verbose hellotr.pro"
hellotr_la.ts file is created.

3.after running "linguist hellotr_la.ts"
hellotr_la.qm file is created.

=xml format =================================
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE TS>
<TS version="2.0" language="th_TH" sourcelanguage="en_SG">
<context>
<name>QPushButton</name>
<message>
<location filename="main.cpp" line="63"/>
<source>Hello world!</source>
<translatorcomment>Orbis, te saluto !</translatorcomment>
<translation>Orbis, te Saluto!</translation>
</message>
</context>
</TS>

i build and run successfully, but it is always same language "hello world"

SGaist

Hi,

@translator.load(“hellotr_la”); << Used like that it searches for the file in the application path@

Do you have the translation file in the same folder as your application ?

houmingc

I don't have the translation file. Where to get it? do you have the link?

i am following the link below
http://qt.developpez.com/doc/4.7/linguist-hellotr/

did i miss anything?

houmingc

there are 13 label that i would like to toggle between thai language and english. I will be using QxmlStreamReader to read both language.

SGaist

There's no need to add QxmlStreamReader for this.

You have generated the hellotr_la.qm file. Probably in your source folder. So you have two solutions here:

Copy that file in the build directory, in the same folder as your application

Give the full path to that file to QTranslator

Can guide on how to toggle between thai and english language using a timer on Mainwindow? Many thanks

houmingc

I managed to toggle between two language. Now my concern is how to plug English and thai from a txt file.
In these txt file, there is a translation list. (English & Thai)

QString line;

do {
line =stream.readLine();
qDebug()<<line;
}while(!line.isNull());
