My Issue/Question:

Hi,

I was getting the click behavior using two ButtonBehavior(), one left click (with ImGuiButtonFlags_MouseButtonLeft flag) and one right click (with ImGuiButtonFlags_MouseButtonRight flag).

bool mouseClicked = ImGui::ButtonBehavior(ImRect(fftAreaMin, wfMax), GetID("WaterfallID"), &mouseHovered, &mouseHeld,
                                                  ImGuiButtonFlags_MouseButtonLeft | ImGuiButtonFlags_PressedOnClick);

        bool mouseRClicked = ImGui::ButtonBehavior(ImRect(fftAreaMin, wfMax), GetID("WaterfallID"), &mouseHovered, &mouseHeld,
                                                  ImGuiButtonFlags_MouseButtonRight | ImGuiButtonFlags_PressedOnClick);

However, I get the following image with the io.ConfigDebugDetectIdConflicts added since commit number d1ea03b872c1de31ab4c0167cf959dffe947cbeb.

Here I have a basic situation and two questions.

I think the io.ConfigDebugDetectIdConflicts parameter is not implemented because it is still in development. Therefore I cannot close this error ("Unless I patch it manually"). Will it be added???

Secondly, I use two ButtonBehaviour's to achieve this behavior. I tried different ways:

• When I assigned different IDs with GetID, right click did not work
• I defined left click and right click simultaneously and then used IsMouseClicked to detect whether it is right or left, but it did not work)

So, how can I encourage with this issue?

bool mouseClicked = ImGui::ButtonBehavior(ImRect(fftAreaMin, wfMax), GetID("WaterfallID"), &mouseHovered, &mouseHeld, ImGuiButtonFlags_MouseButtonLeft | ImGuiButtonFlags_PressedOnClick); bool mouseRClicked = ImGui::ButtonBehavior(ImRect(fftAreaMin, wfMax), GetID("WaterfallID"), &mouseHovered, &mouseHeld, ImGuiButtonFlags_MouseButtonRight | ImGuiButtonFlags_PressedOnClick);

That's an interesting use case. I think it this specific case indeed did work before (even if it should be illegal). I will investigate this.

I think you can use single button with both ImGuiButtonFlags_MouseButtonLeft | ImGuiButtonFlags_MouseButtonRight and then checking which mouse button was clicked or released? This should work.

You can surround this block of code with:

PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true);
ButtonBehavior(...)
ButtonBehavior(...)
PopItemFlag();

It legally fixed like this:

bool mouseClicked = ImGui::ButtonBehavior(ImRect(fftAreaMin, wfMax), GetID("WaterfallID"), &mouseHovered, &mouseHeld,
                                                  ImGuiButtonFlags_MouseButtonLeft | ImGuiButtonFlags_MouseButtonRight | ImGuiButtonFlags_PressedOnClick);

It gathers if mouseClicked and then;

if (mouseClicked && !targetFound) {

    if (IsMouseClicked(ImGuiMouseButton_Right)) {
          ......
    }  
    else {
          ......
    }
}

It solved my problem but if you consider to investigate, Issue can be open remain.
