Nav parameter for preventing focus loss by pressing ImGuiKey_Escape?

[Sk44rt]

Details:

My Issue/Question:

I need to disable the loss of navigation focus when the ImGuiKey_Escape button is pressed
I've been looking for a solution for the last four days. but didn't find anything
then I started looking at what lines in imgui.cpp could be commented out so that the focus would not be lost
and i found it!

imgui/imgui.cpp

Line 13347 in c4bc674

g.NavId = 0;

if g.NavId is not set to 0 then navigation focus remains

I think we can add bool parameter to ImGuiContext for preventing focus lost
something like NavPermanentFocus
and code:

if (!g.NavPermanentFocus)
    g.NavId = 0

and also, with this solution, focus can move to other items/windows/popups

I thought there was an issue dedicated to this but I cannot find it..
However some related issues: #3200 #2048 #1074
They are related because I think we need a design that covers all those options, even if e.g. #3200 is asking for something that goes the opposite way of your request.

I do agree we need a solution.

@Sk44rt To gather some context, would you mind writing some more about your usage?
Can you confirm that you essentially want keyboard highlight to always be visible, aka essentially ImGui will be the only user of keyboard inputs in your application?

Yup, ImGui is the only user of keyboard input

Some context
I'm trying to make a Kodi-like application specifically for usage on big screens (e.g. TV), so Keyboard/Gamepad will be the only way to navigate the UI (for which ImGui is used)
and losing focus is the only problem I've encountered

I have added a few things related to those requests:

• Nav: added io.ConfigNavCursorVisibleAuto and io.ConfigNavCursorVisibleAlways config options (ab9ce2a).
• Nav: added SetNavCursorVisible() to override current state (634a7ed).

Technically I think the config options are sufficient for most people and would solve this, but SetNavCursorVisible() may also occasionally be useful (e.g. during startup to present both modes, while staying in Auto mode).

Other tangentially related options:

• Nav: added io.ConfigNavEscapeClearFocusItem (7a56b41).
• Nav: added io.ConfigNavEscapeClearFocusWindow (b001038).
• And a couple of related fixes for all the above.

I'm closing this and other related issues as normally solved, but feel free to comment or open new issues if you have question or problem related to those.

(

Also note, if you have mods using internals, that those two fields have been renamed internally:

• Terminology has been changed to call this the "nav cursor" more consistently.
• bool NavDisableHighlight -> became bool NavCursorVisible (with opposite value).
• bool NavDisableMouseHover -> became bool NavDisableMouseHover

@ocornut

• bool NavDisableMouseHover -> became bool NavDisableMouseHover

Is there any typo? I don't see the difference.
I am having problem in first trying ImRad, because NavDisableMouseHover is undefined.
