There is a routine for python - http://www.sidefx.com/docs/hdk11.0/hdk_soho_examples.html#HDK_SOHO_Examples_Hello2 [sidefx.com]
hou.ui.displayMessage()
however this:
HOM_Module &hou = HOM();
hou.ui().displayMessage(“test”);
doesn't work in C++.
Is it possible to print something in the way like python ones in HDK 11?

I've modified the HOM example [sidefx.com] from the toolkit source to display a message.

You need to include <HOM/HOM_ui.h>

Then, just call:
hou.ui().displayMessage(“Hello world”);


Little known fact, there's a C++ interface for HOM too.

It just crashes. Maybe it works in HDK 13, but not in HDK 11.1

Works for me in H11.1.388

Does the HOM SOP work without the modifications? It might be something else in your environment.

I've found that the use of `hou.ui().displayMessage()` can crash when called from a `DM_SceneRenderHook` render function.
