[mcclim-devel] For panes, :menu-bar height is always zero.

[Dave Goel]

I am playing with a new mcclim, downloaded yesterday or so via
clbuild. 

If I specify a :menu-bar for a pane explicitly, the height is always
zero, no matter what.  My current workaround is to use
clim-internals:make-menu-bar.

As an example, I am attaching a file, with several menubars. Moreover,
I switch the layout of the menu-bars dynamically (and can even
show/hide some bars as I want) using the movethingsaround button.


See the commented out parts in there like:
   ;;(pane2 :menu-bar :command-table 'menubarb-command-table :min-y 100
which I had to replace with clim-internals:make-menu-bar.

I am both attaching as well as including the file below.

Thanks a lot.

;;; This example manually specifies the menu-bar panes.
;; Not only that, each menu-bar's submenu is further a command-table

;; Notice that the quit button is greyed out for mcclim because we
;; defineed it via define-command-table. We should have defined it via
;; define-frame-tag-command-table instead!

;; This method does not work for mcclim.
