MouseOverTextEvent over specific word of text

[kushal256]

Hi,

Was trying to capture events when the mouse is over certain words of text. Currently looks like there is a MouseOverTextEvent, which captures the begin and end of when mouse enters a StyledTextAreaView. Is there anyway to capture when the mouse moves over different words within a StyledTextAreaView?

Was looking at end of StyledTextAreaView::mouseOverTextEvents(), would the implementation be similar to this method? Wanted to avoid using addEventHandler(MouseEvent.MOUSE_MOVED, e-> {}) b/c MouseOverTextEvent has the nice mouseOverTextDelay funtionality, so this looks more logical location.

Thanks!

Hi,

can't you recover the word from MouseOverTextEvent#getCharacterIndex()?

[kushal256]

Ah yes, you're right, I can use this. Was looking for a row+col pair instead of a character index, but found I can use

offsetToPosition(MouseOverTextEvent#getCharacterIndex().getCharacterIndex(), Bias.Forward);

Thx, will close this.

👍

FWIW, I do think we should expose more row+col based API.

[kushal256]

How do you want to expose?

Maybe add to javadoc as an example? Or could add a cover method (e.g. StyledTextArea::getRowCol(int charIndex) ) that simply does this, so users do not have to think about Bias.Forward, and Position.Major, Position.Minor?

I like that idea because the naming itself is a steeper learning curve than it needs to be.

I meant to have versions of methods that take row & column (or Position), instead of an absolute index. In many cases this would even be more efficient.
