parameter hint

[Lacak2]

Is there planed such feature:
when I type parameters for procedure, function, method, that in hint window is displayed name and type of expected parameter ?

There is, look at Environment - Options - Editor - Automatic features - tooltip expression evaluation

[Lacak2]

Hm, is there, is checked, but I see nothing when I write code.
For example when I write:
  SQLQuery1.SQL.Text:=copy(
here I expect hint for parametes for copy function:
 S; Index, Count: Integer
...

Try Shift-ctrl-space while the cursor is inside the brackets.

Or whatever key combo is assigned to:
"Key-Mapping" => "Code tool Commands" => "Show Code Context"

[Lacak2]

  Yes it works, thanks.
But not for copy() function, which I tested ... interested!
Automatic (Delphi like) showing tooltip, without need of pressing Ctrl+Shift+Space is not possible ?

I support Lacak2's feelings; I'm using Lazarus for 8-10 hours per day on a fairly big & complicated project, and also miss the automatic display from Delphi...

Where in the Lazarus sources would the best starting point be to find how to implement this ?

[Leledumbo]

I found that automatic features like this won't work if the source has errors. For the Copy function, I think it's because it's not a true function, but instead a special keyword that will be replaced by the compiler with the proper function call. That's why Copy works perfectly for arrays.

Looks like this feature stopped working in 0.9.26-2. Can anyone else confirm or put me out of my misery?

[Martin_fr]

I don't know about 0926, but it works in 0927 (daily snapshot). 0927 also works for copy and similar.

[desmondc]

Just weird.

I changed the key combination to alt+shift+right. That worked. I used to have ctrl+shift+right. I last set it up in 0.9.22 and kept on copying the xml prefs files ever since on new installations.

Maybe my IceWM has some special bla-bla for ctrl+alt key combinations.

Well, at least I'm out of my misery now.

This calls for celebration, excuse me while I open my bottel of Wyborowa (you see i have been miserable for a while since not been able to use the paramter hint)
