[solved] Translation on the fly crashes

SGaist

Are you sure translator is valid ?

skwateur

@MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
translator = new QTranslator(0);@

I can translate the whole program while being on MainWindow. As soon as I go into a widget, I can no longer translate the program. It crashes :s

SGaist

That's in the MainWindow, how do you do it in your widget ?

skwateur

I emit a signal from the widget which is then caught by the main window :
WIDGET :
@void ui_sys_settings::languageToEn()
{
emit toEnglish();
}

void ui_sys_settings::languageToFr()
{
emit toFrench();
}@

MAINWINDOW :
@connect(sysSettings,SIGNAL(toEnglish()),this,SLOT(changeToEnglish()));
connect(sysSettings,SIGNAL(toFrench()),this,SLOT(changeToFrench()));

void MainWindow::changeToFrench()
{
if(!translator->isEmpty())
qApp->removeTranslator(translator);
}

void MainWindow::changeToEnglish()
{
if(!translator->isEmpty())
qApp->removeTranslator(translator);

translator->load("dcl_en",QApplication::applicationDirPath());
qApp->installTranslator(translator);

}@

SGaist

Are you sure you need to re-install the translator ?

skwateur

I only install it when I load the english language file. It is never installed otherwise

SGaist

Strange...
Could you post/share a minimal compilable example that shows the problem ?

skwateur

hmmm. post an example from my own program ?

SGaist

Rather the minimal code that reproduce the crash

skwateur

Oh. The code that produce the crash is the code I have posted above.

If I take the instruction " qApp->installTranslator(translator);" off, then it doesn't crash. But I have nothing translated lol

SGaist

Indeed, but with only pieces of code, I can't try to reproduce the crash.

skwateur

oh. Do you want the full code of the class ?

skwateur

Or I can send you the source files by email if you want. Maybe it could be easier for you to see what's wrong

SGaist

You can also use a service like "pastbin":http://pastebin.com/

skwateur

Should I paste all my code with pastbin SGalst ?

SGaist

Only what is needed to build and trigger the crash

skwateur

It is a graphic application. You would need the images files to be able to hit the button.

Any way I can give it to you ?

SGaist

What do you mean by "images files to be able to hit the button" ?

skwateur

In order to trigger the crash, you have to run the application then hit a button to load a widget. Then you have to hit another button to start the translation. (and then it crashes).

If you want to trigger the crash yourself, you would need the whole program I think. (I have got too many classes ad I don't really know what is the minimal stuff you would need to be able to compile it)

skwateur

It used to work fine before. Dunno what I changed, god damn it it's driving me crazy
