Описание

Make a label in front of some control.

Предпросмотр текстуры в окне редактора.

Note that most editor controls already have built-in optional labels that can be specified as one of the parameters. PrefixLabel can be used when there is no such built-in label available, or when you're creating your own editor control from scratch.

PrefixLabel takes a rect that's the rect for the entire control, including the label, and returns a rect that's for just the control itself, without the label.

PrefixLabel also ensures that when the label is clicked, the linked control will get keyboard focus (if the control supports keyboard focus). The ID of the linked control can optionally be specified, or if no ID is given, the label is automatically linked to the following control coming after it.

	// Inflates a mesh
	//
	// Usage: Select a mesh and drag it to the object field.
	// Press calculate and after finishing just press play and see your mesh growing.
	//
	// Note: To control the ratio of inflation just change the increaseRatio 
	// var in the "InflateMesh.js" sript
