Need don't show this message again check box in QMessageBox with YesNo button

[Rajesh.Rathod]

Dear All,
I want to have "Don't show this message again" check box in QMessageBox with Yes & No buttons , is there a way in Qt to achieve it ?
I know there is QErrorMessage which gives this check box but I also need yes no button.

Please help.

Thank you,
With Best Regards,

Hi, ugly hack:
you can derive a class from QMessageBox, and if you look at the Qt sources you can see that QMessageBox uses a QGridLayout internally (at least in Qt4). You can get this using layout (), and then add a widget like a checkbox to it.

This depends on Qt internals, so maybe/probably there is a better way to do it.

edit: of course you could just create a custom dialog for this...

Since Qt 5.2, QMessageBox supports setting custom check box with QMessageBox::setCheckBox method. If you are using older version, you will have to create a custom widget yourself.

Dear All,
Thank you very much for you help, I am using Qt 4.7.3 so can't use the latest API.

Actaully, I found a workaround here...

QMessageBox msgBox;
QCheckBox dontShowCheckBox("don't show this message again");
msgBox.addButton(&dontShowCheckBox, QMessageBox::ActionRole);

QMessageBox msgBox;
QCheckBox dontShowCheckBox("don't show this message again");
msgBox.addButton(&dontShowCheckBox, QMessageBox::ActionRole);

To copy to clipboard, switch view to plain text mode 

This seems to work for me, of course I need to connect signal slot and then I need to maintain it's checked state somewhere in my application....

Thank you.
