Hi. Another little thing that I find annoying in Houdini. I often need to select a node and set display flag. That right now is two clicks. Is there any chance that there is a key modifier that allows the display flag to auto set in any node I select?

This combined with a node info panel that would show info of node selected automatically (without middle mouse button click) would be so handy in inspecting scenes and trying to follow what’s happening.

Hold down the display flag key ‘r’ when clicking to move the flag on click.

Doing either of those things on selection would cause unnecessary cooking, since most of the time selecting a node is for accessing the parameters or moving the node around.

Houdini already cooks on selection by default.

You can use addEventCallback:
https://www.sidefx.com/docs/houdini/hom/hou/Node.html#addEventCallback [www.sidefx.com]

with hou.nodeEventType.SelectionChanged:
https://www.sidefx.com/docs/houdini/hom/hou/nodeEventType.html [www.sidefx.com]

and:

node.setDisplayFlag(True)
node.setRenderFlag(True)
node.setGenericFlag(hou.nodeFlag.Template, True)

Thanks but where should I put this code to be active when Houdini starts?

node.setGenericFlag(hou.nodeFlag.Template, True)

Where to put this code?

You have to turn this into a function and then register it like this (this one is using name changed event):
def name_changed(node, event_type, **kwargs):
    print("The geometry object is now named", node.name())

hou.node("/obj/geo1").addEventCallback((hou.nodeEventType.NameChanged, ), name_changed)

But I would recommend a different way. nodegraphhooks actually offers better methods. For example in some contexts I override RMB on a node to diplay that node, but it's a bit more involved to detect what's under the mouse is a node and if so, check the clicked buttons and/or modifier keys.
