It would be great if the user of kdialog could pick a different icon to use. In my case, I'd like to use a warning or error icon with a passive notification (--passivepopup). I'd like to be able to choose from a standard set (e.g., INFO, WARNING, ERROR), but allowing a specific icon file would be nice, too.
kdialog --passivepopup "Hello" 2 --icon dialog-information kdialog --passivepopup "Hello" 2 --icon dialog-error kdialog --passivepopup "Hello" 2 --icon dialog-warning kdialog --passivepopup "Hello" 2 --icon /usr/share/icons/oxygen/base/64x64/apps/oxygen.png
