Hi,
the built in PoseMorph tag in C4D has no problems with this, the sliders fill up the available space.
But my own plugin won't do this.
If I have a Real Slider on its own, all is fine. But like the PoseMorph tag, I want to use a checkbox, a BOOL, to the left of the slider. As soon as I add this, the Real Slider shrinks and becomes very short.

How can I make the slider fill up the available space? FWIW, I have tried several combinations with Layoutgroups etc etc

CONTAINER Tfoobartag
{
	INCLUDE Texpression;
	GROUP FOO_MAIN
	{
		DEFAULT 1;
		COLUMNS 2;
		BOOL FOO_BOOL{}  
		REAL FOO_REAL {CUSTOMGUI REALSLIDER; UNIT PERCENT; MIN 0; MAX 100; MINSLIDER 0; MAXSLIDER 100; }
	}
}

Ok, finally I found the solution, by looking at a bunch of RES files, SCALE_H; will do the trick!
