Is there any way to prevent click events on ImGui from falling into SFML?

[DEAGS3000]

As the title, do ImGui or SFML have this function? Or I need to implement that by my self?

To my knowledge, there's no way of doing this automatically. You could potentially use ImGui::IsAnyItemHovered() or ImGui::IsAnyItemActive() (or perhaps a mixture of the two) to check.

Yep, that's what I wanted to propose. To do so automatically would mean that I'd have to modify SFML's event queue which is not possible because of SFML's interface.

I recently solved this issue in my game by checking ImGuiIO::WantCaptureMouse and ImGuiIO::WantCaptureKeyboard before handling my mouse and keyboard events.

For example:

ImGuiIO& io = ImGui::GetIO();
switch (event.type)
{
    case sf::Event::MouseButtonReleased:
    {
        if (io.WantCaptureMouse) break;
        break;
    }
}

More info:

From ImGui:

You can read the io.WantCaptureMouse, io.WantCaptureKeyboard flags to tell if dear imgui wants to use your inputs.
- When io.WantCaptureMouse is true, do not dispatch mouse input data to your main application.
- When io.WantCaptureKeyboard is true, do not dispatch keyboard input data to your main application.
Generally you may always pass all inputs to dear imgui, and hide them from your application based on those two flags.
