Juce Relative Bounds

General JUCE discussion
1

I have something that has to be simple but I just can't work through it in my head.

 

If I setup a Component to be relative to another component I end up getting 2 calls to "resized". The first with the Left,Top being set and then another one once the Width and Height are set. Am I doing something wrong?

 

projectWizard->setBounds("((effectControlComponent.left) / 2) - 340, ((presetControlComponent.top) / 2) - 238, left + 680, top + 477");

 

if I change effectControlComponents location or presetControlComponents loaction projectWizard::resized() gets called twice.

Presumably something to do with this loop?

    void applyToComponentBounds()

    {

        for (int i = 4; --i >= 0;)

        {

            ComponentScope scope (getComponent());

            const Rectangle<int> newBounds (rectangle.resolve (&scope).getSmallestIntegerContainer());


            if (newBounds == getComponent().getBounds())

                return;


            getComponent().setBounds (newBounds);

        }


        jassertfalse; // Seems to be a recursive reference!

    }

Jules, what's the logic behind running this up to four times but no more?  I was hitting the assertation the other day with something positioning based on its parent. I couldn't see how I'd hit a recursive reference and just worked around it...

It's a pretty arbitrary number, as I assumed nobody would be using layouts with more than 4 levels of nested dependencies.. I'll change it to a bigger value, as that'd still trigger the assertion in a real recursive situation.
