Offset of the CallOutBox

General JUCE discussion
1

Hello,

It seems that the juce::CallOutBox is sometimes shifted vertically to the bottom. In this example, the juce::CallOutBox is not attached to a component and should display a rectangle with its origin at the mouse position. I tested on macOS and Windows with Juce 6.1.2 (master) and 96612b1 (develop).

I click at the bottom of the window and the position seems good:

_Good
_Good1920×1200 44.7 KB

I click at the top of the window and the position seems bad:

_Bad
_Bad1920×1200 44.7 KB

Code:

void MainComponent::mouseDown (juce::MouseEvent const& e)
{
    class Rect
    : public juce::Component
    {
    public:
        Rect()
        {
            setSize(300, 200);
        }
        
        void paint (juce::Graphics& g) override
        {
            g.fillAll(juce::Colours::whitesmoke);
        }
    };
    juce::CallOutBox::launchAsynchronously(std::make_unique<Rect>(), {e.getScreenX(), e.getScreenY(), 300, 200}, nullptr);
}

Your areaToPointTo in the launchAsynchronously is a big square with top left position at the cursor. IIRC according to the quarter where you click in the screen, the CallOutBox will be placed Up or Down or Left or Right to this areaToPointTo target (with the arrow pointed to the area).

In _Good it is Up ; in _Bad it is Down.

Thus for me it seems a normal behaviour. Am i wrong? :thinking:

You should use a smaller size for the target to see what i mean (and click on screen borders).

juce::CallOutBox::launchAsynchronously(std::make_unique<Rect>(), {e.getScreenX(), e.getScreenY(), 10, 10}, nullptr);

Okay, I expected the CallOutBox to be placed in the rectangle but in fact, this is the area that the call-out’s arrow should point towards. I should have read the documentation more carefully. Thank you!
