I'm working on an scientific computing application that makes fairly heavy use of Greek letters in the UI.

It would be convenient if ImFontAtlas had a GetGlyphRangesGreek() method so I didn't have to add every Greek letter to the atlas manually.

Feel free to make a PR for it, thank you.

I don't have a fork handy that I can push to and have some other things to work on.

But the Greek and Coptic Unicode range is U+370 to U+3FF. Here's what I have in my code now.

for(wchar_t i=0x370; i<=0x3ff; i++)	//Greek and Coptic
	builder.AddChar(i);

How about U+1F00 Greek Extended, what is that useful for ?

I'm not sure as I don't actually speak the Greek language, I just use the letters in math :)

What about adding a GreekFull glyph range, similar to what you have with Chinese, that adds that range as well as the base one?

Thanks for the PR. I think i'll merge as is for now, I prefer getting feedback on incomplete ranges.
(Anyhow hopefully those functions will eventually be gotten rid of..)

    Additionally SetActiveIdUsingAllKeyboardKeys() doesn't set ImGuiKey_ModXXX but we never need/use those and the system will be changed in upcoming commits.

    Replace BeginMenu/MenuItem swapping g.NavWindow with a more adequate ImGuiItemFlags_NoWindowHoverableCheck.
    Expecting more subtle issues to stem from this.
    Note that NoWindowHoverableCheck is not supported by IsItemHovered() but then IsItemHovered() on BeginMenu() never worked: fix should be easy in BeginMenu() + add test is IsItemHovered(), will do later

commit d5d7050
Author: ocornut <[email protected]>
Date:   Thu Sep 29 17:26:52 2022 +0200

    Various comments

    As it turns out, functions like IsItemHovered() won't work on an open BeginMenu() because LastItemData is overriden by BeginPopup(). Probably an easy fix.

    Renamed and merged keyboard modifiers key enums and flags into a same set:. ImGuiKey_ModXXX -> ImGuiMod_XXX and ImGuiModFlags_XXX -> ImGuiMod_XXX. (ocornut#4921, ocornut#456)

    Changed signature of GetKeyChordName() to use ImGuiKeyChord.
    Additionally SetActiveIdUsingAllKeyboardKeys() doesn't set ImGuiKey_ModXXX but we never need/use those and the system will be changed in upcoming commits.
