BR: dangling pointer with options.getTargetComponent()

Called with already deleted function
how are you creating the menu? are you forgetting to delete a pointer in the destructor?

Notice that this error message is mine. :grinning_face_with_smiling_eyes:

void drawPopupMenuBackgroundWithOptions (juce::Graphics& g,
    int width,
    int height,
    const juce::PopupMenu::Options& options) override
{
    juce::Component *c = options.getTargetComponent();
    const bool isBox = (dynamic_cast<juce::ComboBox*> (c) != nullptr);
    const bool isBar = (dynamic_cast<juce::MenuBarComponent*> (c) != nullptr);
    
    if (isBox) {
        g.fillAll (juce::Colours::green);
    } else if (isBar) {
        g.fillAll (juce::Colours::blue);
    } else {
        g.fillAll (juce::Colours::red);     DBG ("Called with already deleted component!");
    }
}

I’ll extra check today, but i don’t think i’m doing something wrong. Isn’t it?

Thanks for reporting. When the menu is dismissed it calls a lambda that captures the menu bar component. It looks like this lambda just needs to add a check that the menu still exists before trying to use it. I’ll make that change shortly and update this thread once the change is on develop.

Thanks for your patience. I think this commit should resolve the issue:

Please update, and let us know if you run into any further problems.
