How QMessageBox can be inherited.

[rajveer]

but that was used with QPushButton, but in ur code u are using QAbstractButton. So the problem is coming when we use tr.
that is:

addButton(tr("OK"), QMessageBox::Ok);

error is:

'void QMessageBox::addButton(QAbstractButton *,QMessageBox::ButtonRole)' : cannot convert parameter 1 from 'QString' to 'QAbstractButton *'

[spirit]

I built this code before post it.

[rajveer]

so now what should i do. pls help me.

[spirit]

try this project

[rajveer]

hello sir, i m doing just like this, but still it is giving the same error.

[spirit]

ok, I don't understand why this happens. anyway, try this insted

...
QPushButton *myOk = new QPushButton(tr("Ok"));
addButton(myOk, AcceptRole);
...

...
QPushButton *myOk = new QPushButton(tr("Ok"));
addButton(myOk, AcceptRole);
...

now two errors r cuming.

1) 'QPushButton' : class has no constructors
2)'void QMessageBox::addButton(QAbstractButton *,QMessageBox::ButtonRole)' : cannot convert parameter 1 from 'QPushButton *' to 'QAbstractButton *'

[spirit]

include QPushButton or just QtGui.

What Qt version are u using ? Are ur paths properly included ?

I tried the test.zip, and it works fine without any error. I have Qt 4.3.4.

[rajveer]

what abt this error:

'void QMessageBox::addButton(QAbstractButton *,QMessageBox::ButtonRole)' : cannot convert parameter 2 from 'QMessageBox::StandardButton' to 'QMessageBox::ButtonRole'

[rajveer]

i have used 4.3.2

[aamer4yu]

Where are u getting that error ?
What i did was extracted the test.zip, ran qmake -tp vc , and built the project from visual studio. No errors.

I dont know what u are doing... u must be missing something

[rajveer]

i m just doing the same , but it is giving an error which i have already told.

i have displayed a message by using QMessageBox and i have done all the translation related to my message but the Yes / No option cannot be translated. So how can it be done.

It's enough to provide translations for the proper context and message. Look into the source code of QMessageBox to see what it expects. There is really no need to making things more complex than they really are.

[rajveer]

Its not working , how the QMessageBOx button can be translated.

[wysota]

What is not working? What exactly did you do?

[spirit]

use QObejct::tr and Qt Linguist for translation.

[rajveer]

i have to change all the buttons which are coming when we are using QMessageBox in the application . the text message is changed by using tr but the OK , yes, No buttons can not be changed. so how can i do this?

my mentor said u hav to create a class and derive it from QMessageBox and then remove that buttons and add ur own buttons. but how can i do that. means i have using it in one way which the other sir told me in the forum.

[wysota]

You don't have to do anything like that. Read my post again, it says exactly what you need to do and believe me it will work as Qt does it exactly the same when it translates the message box with a proper translator installed.

[tone]

My distribution of Qt has translation files for a bunch of languages, which translates the texts and labels of the standard Qt buttons (and possibly other standard stuff as well).
If you install a translator loaded with the correct file your standard buttons will have their text translated for you.
Would that answer your needs?
in my PC the translations are located in C:\Qt\4.4.0\translations\*
Pick the one that suits you and then install it using this code:

QString trans_file("<translation_file_path>");
trans_file = trans_file.toLower();
QTranslator qtTranslator;
qtTranslator.load(trans_file);
qApp.installTranslator(&qtTranslator);

QString trans_file("<translation_file_path>");
trans_file = trans_file.toLower();
QTranslator qtTranslator;
qtTranslator.load(trans_file);
qApp.installTranslator(&qtTranslator);
