careful --- re-running the compile when th eissue is the one I pointed at can sometimes run successfully...

I'm running into some undefined parameter warnings that I could use a hand with.
I have a function that adds a childPanel to an existing panel. The paint routine is triggering Warning: undefined parameter 0 if the panel hasn't been created yet, or if the childPanel has been removed.

	inline function addButton(panel)
	{
	    local button = panel.addChildPanel();
	    button.set("allowCallbacks", "Clicks & Hover");
	    
	    button.setPaintRoutine(function(g)
	    {
	        g.setColour(this.data.hover ? Colours.red : Colours.blue);
		g.fillPath(myPath, [10, 5, 14, 14]);

	    });

	}

Is there a better way to do this that won't throw these warnings?

@Dan-Korneff

	inline function addButton(panel)
	{
            if (!isDefined(panel))
                return;

	    local button = panel.addChildPanel();
	    button.set("allowCallbacks", "Clicks & Hover");
	    
	    button.setPaintRoutine(function(g)
	    {
	        g.setColour(this.data.hover ? Colours.red : Colours.blue);
		g.fillPath(myPath, [10, 5, 14, 14]);

	    });

	}

@d-healey Perfect! Simple and effective.
Actually, this method still returns errors

@Dan-Korneff

Actually, this method still returns errors

Explain

[Dan Korneff]

@d-healey I've added this to the childPanel functions:

            if (!isDefined(panel))
                return;

• Run the function that creates the child panel.
• Close the panel.
• Hit F5 to recompile All Scripts.

Then I get Warning: undefined parameter 0

After closer inspection, the warning is pointing to the line that contains fillPath. I can confirm that this path is being defined. It points to all paint routines

[Dan Korneff]

Here's a basic example:

Load it up and hit F5

[d.healey]

@Dan-Korneff There's something really weird going on there because even if I delete everything in the script I still get the error when hitting F5.

[d.healey]

Oh I found the solution (still not sure why it goes crazy even when the script was cleared though).

Child panels are kept between recompiles, so it's necessary to clear them all out before adding them. Just put this after you create the parent panel.

for (x in Panel1.getChildPanelList())
	x.removeFromParent();
