Is it possible to spawn a (specific) placeholder exactly at the position at which a new window would spawn?

Currently, I used

i3-msg append_layout file

with file being

"name": "aa",
    "swallows": [
          "class": "bb",
          "instance": "cc"
    "type": "con"

However, this window spawns at the top-node of the workspace (i.e. on the very right/bottom).

Maybe there is another possibilty to create those handy placeholder windows?

One can simply use

i3-msg "workspace dummy; append_layout file; focus child; move window to workspace back_and_forth; workspace back_and_forth"

Here, dummy is a workspace which is not used elsewhere. The only drawback seems to be that this command changes back_and_forth.

Nice idea. You can of course fix the drawback by moving to the previous workspace first and saving its name.

Let me sketch a possible solution (assuming that “aa” is a unique name). First, move the layout window to the scratchpad automatically by adding the following line to the config file:

for_window [title="^aa$"] move scratchpad

Next write a script that places the placeholder as follows. First it should issue the append_layout command. Then it should wait for the layout window to be opened (you can subscribe to i3 events, which I won't go into, or use an ugly solution that waits in loop and checks every, say, 0.01s whether the window has been opened). When it has been opened, it should issue two commands:

  • [title="^aa$"] scratchpad show to show the layout window.
  • floating disable to make it tiling in the current position.

Thank you for your valuable input. By playing around with your suggestion, I have found an easier solution.
