Hello,

Why in some of my Lazarus project, sometime mouse over help context
disappears ?

It works very well for some of my projects, and for others, the aid
disappears suddently and never come back...
It's difficult to work without this.

Because my english is bad, better to put an example:

FList: TList;
...
FList.

And after the '.' I wait... I wait... I wait... and no method/property
appears 


When this happens, there isn't also no debug info when after a break
point, I put the mouse over a variable...

I don't change any options in IDE environment.

Thanks you for you help

Usually this situation happens when code-tools parser encounters code
that it is unable to parse.

If things are really bad, then code-tools even emits an error in the
log window.

In order to 'force' the method/property list you can press ctrl+ space
directly after the dot to invoke the popup window.

which version of lazarus and on what platform are you confronted with
this behaviour ?

iirc menu->view->messages.

it is the default message window where you also see the output result
of your compilation.

I'm using anchordocking myself so the message window is always there
for me.

Thanks Molly for you help.

I will take a look to my code.

Note that code-tools failing can be encountered with something as
simple as forgetting to include the correct unit in the uses clause
(or included at the wrong location e.g. implementation section instead
of interface section)

Other causes of failure for code-tools includes the inability to
locate the (correct) source files or include files.

Mostly (for me) it is just about a dumb typo that was made somewhere.
Also note that in case forcing the method/property window with ctrl-
space fails, that you can be certain that something is amiss inside
your code. Depending on the severity of the error, code-tools emits an
error/hint or none at all.

Compiling your project usually tells where the error is exactly, in
case you are really overlooking things.

In case the popup hints keeps failing for you after you have corrected
your code, then there might be something wrong. Please report in that
case and preferably show some example to reproduce.
