Hi,

#define ITEM "textToTranslate"

how can i translate it?

You could try:

#define ITEM QT_TR_NOOP("textToTranslate")

and then tr(ITEM) but in general using such defines in C++ is not a very good approach.

Much cleaner solution is:

const char * const ITEM = QT_TR_NOOP("textToTranslate");
 
 
sth->setText(tr(ITEM));

const char * const ITEM = QT_TR_NOOP("textToTranslate");


sth->setText(tr(ITEM));

To copy to clipboard, switch view to plain text mode 

and second, i have in file some text, which is loaded into QDraw.

What is QDraw?

how can i transtale this text. text for translating is still same.

You'd need to manually teach your message catalog about the string to be translated. It's better to avoid such solutions. What do you need it for?

A possible solution could be to reimplement QTranslator::translate().

[stevocz]

thank you for reply.

i am try
#define ITEM QT_TR_NOOP("textToTranslate")

and then tr(ITEM)

but doesnt work. textToTranslate missing in ts file.


What is QDraw?
sorry i mean in painter drawText

i have one application which create xml file and text. this text is for show in second application

[wysota]

thank you for reply.

i am try
#define ITEM QT_TR_NOOP("textToTranslate")

and then tr(ITEM)

but doesnt work. textToTranslate missing in ts file.

So use the other possibility I gave you.

[stevocz]

second possibility doesnt work too. after lupdate, textToTranslate missing in ts file.

[wysota]

second possibility doesnt work too.

Then it means you are doing something wrong, it should work just fine.

[sulliwk06]

maybe i'm missing something here, but isn't it SUPPOSED to not be able to translate "textToTranslate" ? Without spaces its not really a word.

[stevocz]

textToTranslat is only example. i have text with spaces and text with only one word.


something is wrong, but i don't know what, because i can't transtale this:

ui->buttonBox->button(QDialogButtonBox::Ok)->setText(tr("Ok"));
ui->buttonBox->button(QDialogButtonBox::Cancel)->setText(tr("Cancel"));
application after start crash

but other things work ok.

[wysota]

application after start crash

You probably get a null pointer from button().

[stevocz]

i am stupid i call Ok button but i have Save button.


but #define or const char * const ITEM still not work

[wysota]

but #define od const char * const ITEM still not work

Please post a minimal compilable example reproducing the problem. Make sure you have the file containing the QT_TR_NOOP macro explicitly added to your project file, otherwise lupdate won't scan it.

[stevocz]

I am edited one example


and QDialogButtonBox text is in .ts file but translate doesn' work. why?

[wysota]

The translation mark is outside a context. Either put it in a context or use QT_TRANSLATE_NOOP instead of QT_TR_NOOP passing a context to the call. Make sure the same context is used with the tr() call.

[stevocz]

can you fix it and send me back this application?

because i am try this:

const char * const TEXT_TO_TRANSLATE = QT_TRANSLATE_NOOP("translateCategory", "Translate");

and "Translate" is in .ts file, but in application text isn't changed.

and please fix QDialogButtonBox

[anda_skoa]

maybe a stupid question, but why translate the QDialogButtonBox strings again?

Those strings from Qt should already be translate for Qt.
If they aren't, maybe the Qt translation catalogue wasn't loaded?
See http://qt-project.org/doc/qt-4.8/i18...ng-translation

when i am erased .ts file and create new, QT_TRANSLATE_NOOP works ok

this

const char * const TEXT_TO_TRANSLATE = QT_TRANSLATE_NOOP("translateCategory", "translate");
ui.label_2->setText(QApplication::translate("translateCategor y",TEXT_TO_TRANSLATE));

and this

const char * const TEXT_TO_TRANSLATE = QT_TRANSLATE_NOOP("QObject", "translate");
ui.label_2->setText(QObject::tr(TEXT_TO_TRANSLATE));

booth work.



or best for this example

const char * const TEXT_TO_TRANSLATE = QT_TRANSLATE_NOOP("MainWindow", "translate");
ui.label_2->setText(tr(TEXT_TO_TRANSLATE));

work too.

[wysota]

and "Translate" is in .ts file, but in application text isn't changed.

Did you modify the respective tr() call to take data from the "translateCategory" context?

[stevocz]

yes, tr() is modified and works. now i must edit QDialogButtonBox.

[wysota]

yes, tr() is modified and works. now i must edit QDialogButtonBox.

No, you just have to load the bundled message catalog for it.

[stevocz]

but how? i am tried load QLibraryInfo but doesnt work
