public final void select(int selectionStart, int selectionEnd)
This method sets the start and end positions of the selected text, enforcing the restriction that the start position must be greater than or equal to zero. The end position must be greater than or equal to the start position, and less than or equal to the length of the text component's text.
If the caller supplies values that are inconsistent or out of bounds, the method enforces these constraints silently, and without failure. Specifically, if the start position or end position is greater than the length of the text, it is reset to equal the text length. If the start position is less than zero, it is reset to zero, and if the end position is less than the start position, it is reset to the start position.
This call is provided for backward compatibility.
It is routed to a call to setCaretPosition
followed by a call to moveCaretPosition
.
The preferred way to manage selection is by calling
those methods directly.
selectionStart
- the start position of the textselectionEnd
- the end position of the text#setCaretPosition

#moveCaretPosition
