Disable CTRL+Tab switcher popup?

[invrainbow]

I'm on commit 77637fd9.

I'm building an IDE-like program and relying heavily on docking to draw the main user interface. I have an "empty section" where I draw my own application. Before, when the user did not have any tab/window focused, I would assume they had the "empty section" focused, and handle Ctrl+Tab manually.

I'm not sure when this happened, but recently I upgraded to commit 77637fd9. Now when the user presses Ctrl+Tab, no matter where they are, this tab switcher popup thingy opens.

Questions in descending order of optimality:

1. Can I just disable this popup completely?
2. If not, can I have it only open when a tab is focused, and not globally?
3. If not, can I exclude the main menu from the list?
4. If not, how can I find the commit where this was introduced?

Thanks!

1. Can I just disable this popup completely?
2. If not, can I have it only open when a tab is focused, and not globally?

Currently you cannot without modifying Dear ImGui. Disabling completely is something Omar has stated would fall out of #4828

3. If not, can I exclude the main menu from the list?

Pass ImGuiWindowFlags_NoNavFocus to ImGui::Begin.

4. If not, how can I find the commit where this was introduced?

The feature its self has been there for ages, but previously it was tied to keyboard navigation. It was enabled by default in 8ce23b3 as a part of #4023.

We have a change hopefully coming in 1.89 which will make it possible to disable ctrl-tab among other things.

The reason the main menu bar doesn't use ImGuiWindowFlags_NoNavFocus is because we don't have a mechanism to globally use ALT to move to that menu bar, therefore it is often the only way to access it with the keyboard. You may however write a copy of the BeginMainMenuBar() and add the flag if wanted.

Thanks for all the info!

After digging through imgui.cpp I successfully disabled ctrl+tab by setting GImGui->NavWindowingTarget = NULL after ImGui::NewFrame() in my code (also nice because I don't have to modify imgui). Do you see any problems down the road with doing this?

Pushed a few new features and you can now do:

#include "imgui_internal.h"

// Disable CTRL+Tab shortcuts (global): assign a "None" route to steal the route to our two shortcuts
ImGui::SetShortcutRouting(ImGuiMod_Ctrl | ImGuiKey_Tab, ImGuiKeyOwner_None);
ImGui::SetShortcutRouting(ImGuiMod_Ctrl | ImGuiMod_Shift | ImGuiKey_Tab, ImGuiKeyOwner_None);

or

// Disable CTRL+Tab shortcuts (if focused): assign a "None" route to steal the route to our two shortcuts, applies focus testing so will only apply if window is in focus chain
ImGui::SetShortcutRouting(ImGuiMod_Ctrl | ImGuiKey_Tab, ImGuiKeyOwner_None, ImGuiInputFlags_RouteFocused);
ImGui::SetShortcutRouting(ImGuiMod_Ctrl | ImGuiMod_Shift | ImGuiKey_Tab, ImGuiKeyOwner_None, ImGuiInputFlags_RouteFocused);

However, as per #4828 we made the exception to allow remapping CTRL+Tab windowing system. Therefore technically the right shortcut needs to be pulled:

if (g.ConfigNavWindowingKeyNext)
    ImGui::SetShortcutRouting(g.ConfigNavWindowingKeyNext, ImGuiKeyOwner_None);
if (g.ConfigNavWindowingKeyPrev)
    ImGui::SetShortcutRouting(g.ConfigNavWindowingKeyPrev, ImGuiKeyOwner_None);

But this is only if you want to both allow remapping AND disabling of the shortcuts.
