Greetings everybody,

I am trying to access selected keyframes from the Animation Editor using this code from the documentation:

channel_editor = hou.ui.paneTabOfType(hou.paneTabType.ChannelEditor)
keyframes = channel_editor.graph().selectedKeyframes()
for parm in keyframes.keys():
    for key in keyframes[parm]:
        key.setValue(2 * key.value())
        parm.setKeyframe(key)

However, the "selectedKeyframes" method always returns empty, no matter how many keyframes I select.

Any idea of what I could be doing wrong? Maybe the "ChannelEditor" is not the same as the "Animation Editor"?

Thanks in advance for any help on this subject

Big thanks to Guillaume from SideFX who could indicate me the problem with my code and how to fix it! I am posting the solution here in case it can help other persons.

The problem was accessing the correct channel_editor (animation_editor). Here is an example that returns selected keyframes from the pane under the cursor:

def get_selected_keyframes():
    pane_tab = hou.ui.paneTabUnderCursor()
    anim_editor = pane_tab.graph()
    return anim_editor.selectedKeyframes()

Just make sure that your mouse is over an animation editor while executing this code
