getOptimalWidth() : Number;
The getOptimalWidth method returns optimal title width, at which the entire title text is visible.
Executing the example requires the SimpleTreeList component with the Tree identifier (see Example of Creating the SimpleTreeList Component).
// Get title caps = Tree.getCaptions(); cap = caps.getCaptions()[0]; // Get optimal width cap.getOptimalWidth(); -> 30
After executing the example optimal width of the first title is obtained.
