Menu issues

[pavel-krivanek]

This issue is an overall collection of issues and wishes related to menus in Spec.

• missing dynamic aspect. The menus miss API for dynamic changes like adding of items to the existing menus (well, not really good practice but sometimes needed)
• disabling of items in the menu bar does not change the appearance of the item however it starts to behave as disabled (does not accept clicks). When the item is created as disabled, it has a disabled visual style.
• navigation with keyboard arrows does not work at all
• menubar has own presenter but currently, it adds no own behavior nor special processing in Morphic
• menubar items with icons have a really nonstandard visual style
• vertical group separators in the menubars have a too big height
• even the items in menu bars that have submenus (normally all except icons) have the arrow for expanding (probably for consistency with standard menu items with submenus). It should be optional
• no way of keyboard navigation (typical accelerators with underscore on related characters are missing)
• the defined keyboard shortcuts do not work. If some other operation to define the related command is needed than it is not clear what to do
• the shortcuts resolving is strange. $o alt is producing Alt + O while $o meta is producing Ctrl + Shift + Meta + o
• the menubars do not reflect the width of the window, they do not wrap if the window width gets smaller then the original width of the menu. Or at least the rest of the menu should be converted to the submenu on the button like ">>"
• more types of separators would be fiine... like separators that expand to all possible width in the menubar so it would be possible to have some menu items aligned to the right.
• the function key F10, of course, does not work on windows to enter the menu
• the submenus have no way how to deal with the situation when their content is bigger than the screen height
• the separators look does not reflect the display scale factor, at least for the vertical ones

Having the same problem of shortcuts resolution while working on iceberg interface :

In document based applications one requires dynamic adding and removing of items to menues. For instance to have a list of MRU (most recently used files) and access / load them via menu again. So dynamic aspect is a valid point to support.

I would also add BIDI support to the list (bidirektional display) for languages reading right to left (RTL) instead of left to right (LTR)

many of this requests require heavy changes in menus for the morphic backend, and they will not be implemented as part of this release of Spec2, I think (it takes too much time for too few gain, tbh). Other require changes in the VM: F10 (always talking about the Morphic backend). So, I will fix some that I can but forget the idea of getting all that :)

(the Gtk backend already solves most of them, btw)
