[bug_fixed] ZDataset Events in Lazarus

Edwin · Post by **Edwin** » 08.03.2007, 19:41

Hello,

When I try to add an event (like AfterOpen or BeforeEdit) to a ZQuery in Lazarus 0.9.21, I get an error (identifier not found: TDataSetNotifyEvent).

This can be resolved by adding {$IFDEF FPC} DB {$ENDIF} to 'uses' in ZDataset.pas.
I found this solution in the Lazarus forum (thanks to Meg).

Could this be implemented in the next ZeosLib release?

Thanks,

Edwin

Hoi Edwin,

This does not impact Delphi compilation, so I just added and tried a rebuild in lazarus. Looks safe and as it makes you happy I just committed. (Testing branch REV. 227) Is it allright?

BTW, if you can get me a working (command line) test suite for Lazarus, please do so.
Another Lazarus question, how can I recompile and reinstall all packages at once? Is there an easy way to do that? makefile or something like that? I don't have a clue. I just 'open recent package' for every package, 'recompile' and install only component package.

hello ppl,

I had the same problem and tryed to download this revision, but I only found revisons 228 and 234 so I gone for the latest (234). Fixed my problem, but now when I have a TPanel in the same form and try to access field editor (in Lazarus by the way) it crashes the whole IDE. Is there a fix to this ? or it´s Lazarus fault ? I need TPanel

by the way, I got the 234 revision from here:

http://zeosdownload.firmos.at/downloads/snapshots/

Is there any other place to get it ?

No other place to have snapshots, except for getting the source from svn yourself. (See tutorials section)

Yes, and about about the TPanel thing ?

No idea about TPanel. AFAIK no problems in Delphi and the crashing IDE is Lazarus. I'm afraid you'll have to look that way. I didn't hear about other people having this problem however. Until now I had to 'solve' this kind of IDE trouble in Lazarus by reinstalling. That's mainly why I just use it to check if compilation of Zeos is not broken.
I hope some Lazarus expert can give you a decent answer...

Ok Mark,

Lazarus is a project that´s not very mature yet, so we should expect to see more of this sort of thing.
What I did was put a TShape instead of a TPanel and made my code hide and show the components I need one by one. Boring, but works for now.
Thnx for your answer anyway.
