Call rviz func() in C++ Node | save_image deprecated

[DasSchilli]

1. Press on File -> Save Image
   Terminal output
   this function is deprecated, use QScreen::grabWindow() instead. Defaulting to primary screen.
   I want to use this method in my C++ Node, to make a Screenshot from the current scene. Is this possible ?

2. Is it possible to trigger the saving of an rviz config File inside a C++ Node with a spefic filename?

  This is just a warning. Screenshot still works.

No, you cannot trigger that function in rviz from outside.

• Is it possible to trigger the saving of an rviz config File inside a C++ Node with a spefic filename?

Yes, the corresponding service is called save_config:

$ rosservice info /rviz/save_config
Node: /rviz
URI: rosrpc://ares:37369
Type: rviz/SendFilePath
Args: path
