QMessageBox setWindowIcon

Hi,

I have a QMessageBox.
It is QMessageBox::question(0, "WindowTitle","Do you want to Proceed?", QMessageBox::Yes | QMessageBox::No, QMessageBox::No);

By default this QMessageBox has some icon on its window. How can I customize or set different image as its windowicon??

I tried setWindowIcon(QIcon("image.jpg")); it didnt work for me.

Please let me know how do I set the windowicon for this messagebox.

Thanks.

You can't do that with QMessageBox static methods.

You have to instantiate a QMessageBox object (see documentation examples)

hi..Thanks for the reply..

so the code for that looks like..

QMessageBox msgBox;
msgBox.setWindowIcon(QIcon("image.jpg));
msgBox.question(0, "WindowTitle","Do you want to Proceed?", QMessageBox::Yes | QMessageBox::No, QMessageBox::No);


I tried QMessageBox::Question static method and then i used msgBox.setWindowIcon(....) but it is not showing the change..

Hi,

You are still using a static method (QMessageBox::question) and the file path won't always work, you should either put the file in a Qt resource file (and use ":/image.jpg") or in the executable directory (and use QApplication::applicationDirPath()+"/image.jpg"), or a search prefix as in the code below:

Source code

 
1
2
3
4
5
6
7

// In the main function
QDir::setSearchPaths("images", QStringList(QApplication::applicationDirPath()));
...
QMessageBox msgBox(QMessageBox::Question, "WindowTitle","Do you want to Proceed?",QMessageBox::Yes | QMessageBox::No, 0 );
msgBox.setWindowIcon(QPixmap("images:image.jpg"));
msgBox.setDefaultButton(QMessageBox::No);
msgBox.exec();


And you should probably not use a JPG file as an icon because it doesn't support transparency.

Thanks a lot.. It worked for me..

I tried this..

QIcon icon("C:/folder/image.png");
QMessageBox msgBox(QMessageBox::Question, "Title","Are you sure you want to Proceed?",QMessageBox::Yes | QMessageBox::No, 0 );
msgBox.setWindowIcon(icon);
msgBox.setDefaultButton(QMessageBox::No);
msgBox.exec();

This code worked ..
