The situation is, I have a TabPanel with various Tabs, one of which is a "game-panel", a Control-node with sprites, etc. When the game-panel is active, I want to use arrow-keys to move sprites around. I assigned the arrow-keys to various Inputs ("move-left", "move-right", etc). But I'm running into problems with Focus, and how the input-events are processed. When I do an arrow-key left/right, it moves focus across the TabPanel to different tabs (and going away from the game-panel). Wups.
So what I want to do, is restrict keyboard-input to the one Control-node where everything is happening. I've tried things like grab_focus(), which didn't stop the arrow-up from moving focus "up" to the TabPanel,
thereby allowing the arrow-left/right keys to move around the Tabs.
And there do seem to be a lot of knobs that can be adjusted on Focus:
- focus_mode=click
- gui_input() to handle events
- accept_event() to stop events from propagating
But they all seem "piecemeal", or not quite right - Since the TabPanel is at the top of the scene-tree, wouldn't it get the events first?
So, is there a canonical way of restricting keyboard-events to a selected node? Some recommended model? Or do I just have to manually adjust all of the Nodes involved, until they do what I want, with the arrow-keys?
It might not involve focus, either, I've seen references to disabling inputs, but have no idea how that would work on nodes higher in the tree.
