Multiline tooltips [message #459693]

Hi,
I have a list canvas with several virtual components in it.
I managed to get tooltips for list items by adding mouseHover listener
to the list:

@Override
public void mouseHover(MouseEvent e)
{
IControl item = findUnderMouse();
if (item != null)
{
if (item instanceof ListItem)
{
ListItem li = (ListItem) item;
setToolTipText(li.getToolTipText());
}
}
}

the problem is as follows:
the tooltip string maybe very long (sometimes longer than the screen
width), so I need the tooltop to wrap the string.
how can I do it?
(Tooltips that behave like Eclipse's java doc tooltips will be nice).

Thanks.

You have to create a fake tooltip. See

Thanks for the quick response.
is there utility code in swt for text wrapping?
or generally, figuring the best size for a label that contains a warpped
string?

See SWT.WRAP style hint for Text and StyledText widget.

If you want your Label (created with SWT.WRAP) to be, for example, 300
pixels wide, then you can use Label.computeSize(300, SWT.DEFAULT) to
determine the height that this label will need to be to show its contents.
This will take correct wrapping of its contents at pixel 300 into account.

If you put a '\n' in your text, it will display on a new line.
