Re: Separate area at the top for a serious tab bar

Despite my limited Lisp skills, I am still thinking about tab bars. 8-)

In the Emacs manual I found the following:

"Side windows are special windows positioned at any of the four sides of a frame’s root window"

You seem to know more than I do, so maybe you can help me save some time investigating around.

In NetBeans, you can split the editor vertically and have one tab bar over each half. Emacs' tabbar.el uses the "ruler" area, which is (or was?) a special area on top of each buffer. This way, each Emacs buffer (or "window") has a tab bar at its top. If I split the frame vertically with split-window-below, I get to see 2 tab bars.


From the documentation, I guess I cannot have a "side window" automatically placed on top of each buffer (or "window"), because side windows only apply to entire frames. Is that right?

I have seen that you can nest windows, which are then called "internal windows". Would a tab bar based on that be hard to manage? I guess that the tab bar would then be another Window as far as Emacs is concerned, so windmove-up would then take me to the tabbar over its buffer window, which I do not really want. Buffer windows might also get confused if they suddenly move down in the window hierarchy in order to make room for a tool bar on top. Any tips on how I could approach a new tab bar implementation?


Thanks in advance,
