Hi,

I have a problem with the Grid cell tooltips: it happens, sometimes,
that the tooltip doesn't go away when the mouse is moved outside the
cell or even outside the grid control. In some unknown circumstances
there are also two tooltips displayed at the same time for two different
cells, and one of them doesn't go away, even if the grid is disposed.

Unfortunately this happens in a very complex application I'm writing and
every attempt made to build a simple test case failed. It seems that the
mouse events are lost sometimes, but I can't find a way to reproduce in
a simpler environment.

Any suggestion on how I can track this problem, or set a temporary
workaround (like force a dispose of the tooltip when another is shown) ?

Thanks.

Regards,
Marco.

Hi Marco,

I've seen this problem too. I don't know whats causing it. I spent a
not insignificant amount of time looking at this at one point but didn't
find the cause.

I'll spend some more time looking into this.

It's good that you are aware of the problem. Let me know how I can be of
help.

One of my customers suggested to disable the tooltips at all, at least
until this problem is fixed. A good addition would be a method to
enable/disable the cell tooltips, this may be useful regardless of this
problem.

While debugging this issues I noticed some things:

I don't see a dispose listener added by GridTooltip to the parent
widget, maybe this is why the tooltip doesn't go away at least when the
grid is disposed. One of my customers reported this exception that seems
related:

java.lang.IllegalArgumentException: Argument not valid

at
org.eclipse.swt.widgets.Display.readAndDispatch(Display.java :2968)

Another issue that may or may not be related is that I see a repaint
every time the mouse is moved from one cell to another, even if there
isn't a tooltip displayed. If I understand it correctly, the tooltip is
a new shell that overlays the grid so I don't think that a repaint is
necessary at all.

Regards,
Marco.

Other than this problem, I'm not sure why you would want to disable
them. The SWT Table (windows) has no way to turn them off and it hasn't
been an issue there. Hopefully we can just nail this problem and we
won't need to add that feature.

This looks like a separate problem that is probably exacerbated by the
tooltip sticking around. This is an easy fix.

The table is redrawn when crossing cell lines to allow cell renderers to
have hover effects. The default renderers do not have any hover
rendering so its not obvious why the redraw is needed. It is working as
designed. This is not related to the tooltip issue.

I've added the following bug to track the work to fix this. Please CC

This is not correct. You can turn of displaying of ToolTips in
SWT-Tables/Trees by setting setToolTipText(null). This is essential for
the tooltip support provided by JFace with 3.3-API because the content
of the ToolTip can be something completely different than the data
displayed in the cell (e.g. Name of Person in the Cell / Image in the
tooltip).

Ah, that's interesting, I was looking at the Linux SWT Table and there
aren't cell tooltips when the content is not fully shown, so I tought
that it was an addition of the Grid widget, sorry.

Thanks for the quick fix.

That's platform dependend:
- Win32 => ToolTip when content not fully shown
- OS-X / Linux => ToolTip not shown

I don't see that behavior..? If I call Table.setToolTipText(null) I can
still see inplace tooltips for truncated cells. Were you thinking about
regular tooltips and not inplace tooltips perhaps?

null is for restoring the default behaviour.

Ah ok. I see. I will ensure Grid works this way, except with Grid
there are tooltips for each individual cell (i.e.
setToolTipText(index,String). On those cells where a tooltip has been
set, inplace tooltips will not be shown. And if the tooltip is "", then
it won't get displayed either.

We experience the same issue on Mac OS X now - tool tip doesn't

when tooltip is over it. This is valid only for Mac, on Win everything
works fine. We are using rather fresh version of grid, checked out about
month or two ago.

This is not correct. You can turn of displaying of ToolTips in
SWT-Tables/Trees by setting setToolTipText(null). This is essential for
the tooltip support provided by JFace with 3.3-API because the content
of the ToolTip can be something completely different than the data
displayed in the cell (e.g. Name of Person in the Cell / Image in the
tooltip).

Ah, that's interesting, I was looking at the Linux SWT Table and there
aren't cell tooltips when the content is not fully shown, so I tought
that it was an addition of the Grid widget, sorry.

Thanks for the quick fix.

Marco.

That's platform dependend:
- Win32 => ToolTip when content not fully shown
- OS-X / Linux => ToolTip not shown

I don't see that behavior..? If I call Table.setToolTipText(null) I can
still see inplace tooltips for truncated cells. Were you thinking about
regular tooltips and not inplace tooltips perhaps?

null is for restoring the default behaviour.

Ah ok. I see. I will ensure Grid works this way, except with Grid
there are tooltips for each individual cell (i.e.
setToolTipText(index,String). On those cells where a tooltip has been
set, inplace tooltips will not be shown. And if the tooltip is "", then
it won't get displayed either.

-Chris

Hi,

We experience the same issue on Mac OS X now - tool tip doesn't
disappear as mouse leaves the grid. Also, tooltips block mouse events
from being received by grid, so I actually cannot process click on cell
when tooltip is over it. This is valid only for Mac, on Win everything
works fine. We are using rather fresh version of grid, checked out about
month or two ago.

Regards,
Stanislav
