Unfortunately at least this one is still missing:
LCL/TListView: More complete fix of issue #39708, based on patch by d7_2_laz...
https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/c0c30424debbd95c58fc9e8b98293dba55292d12
... referring to this issue:
Windows, virtual listview, "Item" in "Edited" becomes to be wrong when selection changed during editing
https://gitlab.com/freepascal.org/lazarus/lazarus/-/issues/39708
--> What can we do for to make it work again with the 2.2.4?

Post by: wp on September 28, 2022, 04:35:59 pm

Hmmm... This report is tagged with "milestone 2.4". If I remember correctly, this was some kind of difficult work with some changes deep in the heart of the listview, and I was not sure if we did not break something else.

Title: Re: Lazarus Release 2.2.4
Post by: d7_2_laz on September 28, 2022, 05:17:30 pm

Yes wp (thank you!).
There was also some keeping track of the selection list (around "InitMultiSelList", "UpdateMultiSelList" & co.; cannot see them within the 2.2.4) last april, maybe you remember roughly. I applied those patches as discussed last april (from lazgit), and what i can say is that upfrom these changes the virtual listview, multiselect, did work smart and without any problems regarding this bunch of issues discussed (it was a closed long story for me).
Will it be surely within a 2.4? And how to have it for (on top of) the 2.2.4?

Well, 2.2.4 is done - nothing can change it any more. If you are sure that the committed fix is working and has no side-effects, we can target it for v2.2.6 (or 2.4 - whichever comes first). In the meantime it will be in "fixes" then. Is it only the commit that you cited above?

Title: Re: Lazarus Release 2.2.4
Post by: d7_2_laz on September 28, 2022, 06:54:25 pm

Thank you wp again! Of course i cannot promise there are no side effects at all regarding any potential use case. What i can say that i have a heavy usage of listview in virtual mode w. multiselect, have had a bunch of issues in the past, but ending up with your patches from last april for me it does work smooth and reliable. Ii did not encounter side-effects here anymore.

I fear (sorry) i didn't fully understand the meaning of your last question (‘Is it only the commit that you cited above?’).
Not sure where (from which commit) the InitMultiSelList UpdateMultiSelList etc. at the end came from. At least: i just recompared my "patched" 2.2.2 version against the "main" repository (customlistview.inc, win32wscomctrls.pp, win32wscustomlistview.inc, wscomctrls.pp).
They are identical. So for simplyness i'd refer to the "main" repository in this respect.

Title: Re: Lazarus Release 2.2.4
Post by: d7_2_laz on September 29, 2022, 09:47:48 am

wp, regarding the InitMultiSelList UpdateMultiSelList etc. mentioned, this one appear to implement them:
(obviously missing in 2.2.4 too):
https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/fb64d6ef4d2f1081478d16e3fe7455a8110a52c6

Besides, after a couple of file comparisons (customlistview.inc, win32wscomctrls.pp, win32wscustomlistview.inc, wscomctrls.pp original 2.2.2 vs. original 2.2.4) - for to check if one can do so (i found: yes) - i placed. for test, those files on top of the 2.2.4 (plus two others, only for crossref reasons). After this replacement all works fine again. Same as done with 2.2.2.

Concerning a bunch of previous issues around listview matters those 4 files from "main" are working perfectly for me for half a year, so it would be highly appreciated to know if they will be really published with 2.2.6 rresp. 2.4.

Post by: RadDeveloper on October 01, 2022, 04:42:14 am

Hi Lazarus Team! Since the last release, this issue hasn't been fixed :-(

Here is the bug in this version. Here the steps: Launch Lazarus IDE, Click Project -> View Project Source, then close project1.lpr page, then again Click Project -> View Project Source, then the source page appears to be blank (no project code inside), and cannot compile a project.

Thanks.

Quote from: Handoko

I confirm what RadDeveloper said is reproducible on Lazarus 2.2.2 Linux GTK2.

But that only happens on new project, so the steps to produce the issue are:
1. Start Lazarus
2. File > New > Project > Application > OK
3. Project > View Project Source
4. Close the project1.lpr tab on the Source Editor
5. Project > View Project Source

Title: Re: Lazarus Release 2.2.4
Post by: wp on October 01, 2022, 10:47:20 am

This description of steps is incomplete. I cannot close a project without either creating a new project or opening an existing one (--> Project wizard). What are you doing when the "Project wizard" shown in the attachment appears?

4. Close the project1.lpr tab on the Source Editor

I can reproduce.
Step 4 is close tab on Source Editor, not close the project.

I can confirm this issue with Qt and Qt5 under x11, so it's not gtk2 only problem - but this bug is reproducable only with newly created, unsaved project.

I now made several attempts to merge the changes into the fixes branch. But since solution of these bugs has a long history there were commits that were not backported to main, some were reverted, and some were replaced by the changes that you mention, some were not. Therefore I think it is too risky to introduce other issues into the fixes branch, and I would like you to wait for the v2.4 release which will contain the current code automatically (for sure!) because it will be a snapshot of the main branch at the time when this version will be tagged.

Title: Re: Lazarus Release 2.2.4
Post by: d7_2_laz on October 02, 2022, 08:40:43 pm

wp, absolutely ok with 2.4! I'm fully aware of the complexity of this situation ... and so my main concern had been that the solution will be really part on an official release so that this long story finally does come to a good end.
With the well working files mentioned from "main" I didn't have a single problem anymore since half a year (Windows).
2000 thanks for your great support in this matter over this long time!

Hi all, thanks you for this new release !
I notice a minor bug about TFrames that was already present in previous version (2.2.2).
When we put a frame on a form, the unit of the frame is not automatically inserted in the uses section by the IDE, that results in compile error. We have to do by hand.

Lazarus 2.2.4 (rev lazarus_2_2_4) FPC 3.2.2 x86_64-win64-win32/win64

Attached a project with a main form in Unit1, a TFrame in unit frame_2. To reproduce the bug:
- go to the Unit1 tab
- put a TFrame on the form -> choose frame_2
- compile.

Title: Re: Lazarus Release 2.2.4 - troubles after update
Post by: Lurgainn on November 24, 2022, 06:51:46 pm

Hello,
I used version 2.2.2 of Lazarus-IDE without any problem under Xubuntu 22.10.
Today I updated to 2.2.4 using the official deb files from sourceforge.net like I always do, and the update terminated without any error.

Now, when I start Lazarus (/usr/bin/startlazarus), the splashscreen says that it's "Lazarus IDE 2.2.2", the dialog "Configure Lazarus IDE" show the error "/usr/share/lazarus/2.2.2/" "Error: directory not found", and if I manually change to "/usr/share/lazarus/2.2.4/", the dialog show the warning "Warning: wrong version in ide/version.inc: 2.2.4".
If I ignore the warning and press "Start IDE", I get the warning "Without a proper Lazarus directory you will get a lot of warnings.", but if I ignore the warning, the IDE start without any problem, but the version info is still "2.2.2" in the window title and in the about dialog.

Did I do something wrong while updating? Or has anyone got the same problem?

Thanks for any help that anyone can give me.

It is flaw in the upgrade code.

You probably have package installed, and therefore did rebuild your IDE (it happens as soon as you install a package).
This rebuild version is still cached and used (i.e. you still running a 2.2.2).
The newly installed 2.2.4 on the other hand has not yet those packages compiled in.

So all you need to do (after you changed that path, and ignored the warning), is from the "tools" menu: "rebuild lazarus ..."

After that it should be fine (the packages will then be part of your 2.2.4)

The install guide mentions compiling your own Lazarus IDE with "fixes 2.2". Is this still needed now that we're at 2.2.4?? It's not clear in the install instructions.

If you have a GitHub account you can use that to sign into GitLab. I likely could create a GitLab account, but I just use my GitHub account for GitLab.

The lazarus version 2.2.4 with fpc 3.2.2 using GTK2 under linux ARM processors sometimes the OnShow event not detonated after OnCreateForm (only in ARM Processors).

Lazarus Version:

This has nothing to do with ARM processors. Show us some code - compilable code -... Then you will get more reasonable answers.

in this version, if you put an a Tlabel (Label1 in the picture) inside of TTabsheet (TabSheet5) inside of TGroupBox inside to another TabSheet, the TPageControl with TLabel inside (TabSheet4 and TabSheet5) the TGroupbox can't change the tabs when run the program program or reload the project.

See th picture attached, this is in Linux with any processor

Just only, New Project- add an showmessage inside of OnShow Event and run the program in a raspberry pi 4. Sometimes the code inside onshow dont do nothing.

Code: Pascal [Select][+]

unit unit2;
 
{$mode objfpc}{$H+}
 
interface
 
uses
  Classes, SysUtils, Forms, Controls, Graphics, Dialogs;
 
type
 
  { TForm1 }

end.

Remove the close, because ShowMessage is not modal. That goes for every platform btw.

I probalbly misunderstand you here, but ShowMessage shows a modal dialog on all platforms AFAIK.

Title: Re: Lazarus Release 2.2.4
Post by: Thaddy on February 26, 2023, 02:28:43 pm

On Linux it is not modal, as you can see from the emalgamation of popups while using -glh.
That should not happen if ShowMessage was modal.

Title: Re: Lazarus Release 2.2.4
Post by: PascalDragon on February 26, 2023, 08:19:36 pm

ShowMessage is supposed to be modal, because it's only supposed to return once the dialog window is closed. This means that (per thread) there can only be one such window open.

Title: Re: Lazarus Release 2.2.4
Post by: Thaddy on February 26, 2023, 08:24:07 pm

Which isn't the case on Linux/gtk2..
I know all that.

A modal Window should halt execution before any other code gets executed in the same thread.

Me: stating it is modal.
But you seem to be worng on more platforms than I. So, I win O:-)
