How QMessageBox can be inherited.

[rajveer]

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.

[spirit]

you can get access to dialog buttons using this method
http://doc.trolltech.com/4.4/qmessagebox.html#button

so, in you case you need to do

...
msgBox.button(QMessageBox::Yes)->setText(tr(....));
...

...
msgBox.button(QMessageBox::Yes)->setText(tr(....));
...

To copy to clipboard, switch view to plain text mode 

[rajveer]

i have added a message in message box box , but how the Ok can be changed

[spirit]

this code didn't help?

...
msgBox.button(QMessageBox::Ok)->setText(tr(....));
...

...
msgBox.button(QMessageBox::Ok)->setText(tr(....));
...

To copy to clipboard, switch view to plain text mode 

[rajveer]

yeah it wont work.

[spirit]

this code works fine

QMessageBox msg(QMessageBox::Information, tr("information"), tr("Some inportant information"), 
		QMessageBox::Ok | QMessageBox::Yes | QMessageBox::Save | QMessageBox::Discard);
	msg.button(QMessageBox::Ok)->setText(tr("My Ok label"));
	msg.button(QMessageBox::Yes)->setText(tr("My Yes label"));
	msg.button(QMessageBox::Save)->setText(tr("My Save label"));
	msg.button(QMessageBox::Discard)->setText(tr("My Discard label"));
	msg.exec();

QMessageBox msg(QMessageBox::Information, tr("information"), tr("Some inportant information"), 
		QMessageBox::Ok | QMessageBox::Yes | QMessageBox::Save | QMessageBox::Discard);
	msg.button(QMessageBox::Ok)->setText(tr("My Ok label"));
	msg.button(QMessageBox::Yes)->setText(tr("My Yes label"));
	msg.button(QMessageBox::Save)->setText(tr("My Save label"));
	msg.button(QMessageBox::Discard)->setText(tr("My Discard label"));
	msg.exec();

i did it but it said tr identifier not found.

[spirit]

use QObject::tr(...)

[rajveer]

how i can use it with set text.

and also it shows "use of undefined type Qabstract button" with button means msgBox.button

[spirit]

how i can use it with set text.

see http://doc.trolltech.com/4.4/qobject.html#tr

and also it shows "use of undefined type Qabstract button" with button means msgBox.button

include

#include <QAbstractButton>

#include <QAbstractButton>

To copy to clipboard, switch view to plain text mode 

[rajveer]

msg.button(QMessageBox::Ok)->setText(tr("My Ok label"));

here it shows tr identifier not found.
so here how can i use QObject.

[spirit]

...
msg.button(QMessageBox::Ok)->setText(QObject::tr("My Ok label"));
...

...
msg.button(QMessageBox::Ok)->setText(QObject::tr("My Ok label"));
...

I m doing like this:

void MyMessageBox: QMessageBox(QWidget* parent, const QString& title, const QString& text, const QMessageBox&)
			  {
				 QMessageBox box;
box.removeButton("OK");
box.addButton("OK");
box.exec();
return;

void MyMessageBox: QMessageBox(QWidget* parent, const QString& title, const QString& text, const QMessageBox&)
			  {
				 QMessageBox box;
box.removeButton("OK");
box.addButton("OK");
box.exec();
return;

MyMessageBox: QMessageBox

I guess u are inheriting from QMessageBox,,,
then why are u making another instance of QMessageBox inside the ctor ??

[spirit]

I m doing like this:

void MyMessageBox: QMessageBox(QWidget* parent, const QString& title, const QString& text, const QMessageBox&)
{
QMessageBox box;
box.removeButton("OK");
box.addButton("OK");
box.exec();
return;

it is not working.

please help me out.

I don't understand what do you want to do.

[rajveer]

my mentor said u have to create ur own class and derive it from QMessageBox. After dat then u have to remove the already added button and add ur own buttons.

[aamer4yu]

What do you want to do anyway...
in the first post ur prob was regaarding translation. Now its something else.
If you can tell what u want to achieve, may be we can tell a way..

[spirit]

I asked about your code. nevermind.
example

----h----
#ifndef TEST_H
#define TEST_H
 
#include <QMessageBox>
 
class Test: public QMessageBox
{
	Q_OBJECT
 
public:
	Test(QMessageBox::Icon icon, const QString &title,
			const QString &text,
			QMessageBox::StandardButtons buttons = NoButton,
			QWidget *parent = 0,
			Qt::WindowFlags f = Qt::Dialog | Qt::MSWindowsFixedSizeDialogHint);
	~Test();
};
 
#endif
---cpp---
#include "test.h"
 
Test::Test(Icon icon, const QString &title,
		const QString &text, StandardButtons buttons,
		QWidget *parent, Qt::WindowFlags f)
	:QMessageBox(icon, title, text, buttons, parent, f)
{
	QAbstractButton *ok = button(Ok);
	removeButton(ok);
	addButton(tr("MyButton"), AcceptRole);
}
 
Test::~Test()
{
}
 
---another_cpp_code---
....
Test test(QMessageBox::Information, QObject::tr("information"),

I don't see any trouble. is it hard to you?

[rajveer]

an error is coming:

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