Here you can find the source of clipText(JComponent c, Font fnt, String val, int xFrom, int xTo)
| Parameter | Description |
|---|---|
| c | the component used to clip the text. Width from that component will be used for that purpose. |
| fnt | the Font to use to evaluate whether or not the text fits within the component. If null, Font is retrieved from the component. |
| val | the text to clip. |
| xFrom | starting x position within the component |
| xTo | ending position within the component |
