We don't need to run after the latest GTK version. Even other applications
like GIMP or desktop environments like XFCE switch to GTK3 only now,
because it has become stable. So in fact this is the right point to get
GTK3 fully running and there has already been work put into the last
months. What's missing is people testing it, reporting bugs and maybe also
people who are willing to dig into it to fix those bugs.

@Michael
I have not used the OPM extensively, but I think that once a package has
been registered/accepted, I think the original author must be able to
upload his
own changes.

@silvioprog
Me too. Many other PMs allows the component/library authors to upgrade
their packages. I personally would like to use any procedure instead of
sending e-mail.

Creating such an infrastructure would require a lot of work and time. First
you need a registration/login system for the package developers, a database
to store information about the packages, a mechanism to find
dependencies(currently is done by parsing a json), quotas for users, etc.
More over OPM shouldn't connect directly to the database, you need a third
application running on server side via cgi, also you need some kind of
traffic encryption. Definitely not a one man job.

[Lazarus] Completely solve the GTK trouble

[jiaxing ruan via lazarus]

GTK changes too fast and our GTK3 binding is not updated. We don't have to 
resource to catch up GTK. I suggest we abandon the GTK3 and any later GTK 
version interface and instead create an IUP interface. IUP uses GTK underlying, 
so we don't miss anything. Our apps will look just like when they use the GTK 
widgetset. IUP focuses more on compatibility than GTK. Even software written 
for IUP 3.15 could easily compiled and run with IUP 3.27. IUP also has a 
permissive license. As far as I know IUP is as portable as Lazarus is, so we 
don't have to care about portability, too.

Let me see what's your thoughts.

With my ability I can only leave suggestion. I don't have the skill to do it 
myself nor the finance to hire someone else to do. But I think this is the most 
reasonable move for us.

p/s: We already has an IUP binding, also permissive licensed that we could fork

I don't agree. Especially on Linux (and the BSDs probably as well) that is
part of the OS' package manager, even for macOS there is an open source one
that one can install to handle such things. So a list of required
dependencies would be enough.

This list would also be useful for deployment of the final application
however so that one can either set up an installer / package correctly or
report to the user in a Readme or so what libraries are required.


+1.

Don't distribute binaries, only sources. The binary may not work on all
distributions, you'd need to provide one for all platforms (which you may
not have yourself). It may be outdated, no security fixed applied etc..

Signed packages (tar.gz or zips) really would be very useful.

Thanks for updating! However, I would like to do some changes in "Package
info / Community description" info soon. Where can I change this?

Regarding qt/gtk/cocoa, the component doesn't depend on any widget.

It is not often possible to distribute libraries due to license issues, so
something clear alerting about required libraries would be great.

No such problem here, but I compiled libQt5Pas myself, though I don't 
remember if I compiled it clean or reused from a previous kubuntu release.

IIRC I followed the instructions here

https://wiki.lazarus.freepascal.org/Qt5_Interface#Qt5_on_Ubuntu_18.4

specifically the part where it says "If you wish to build your own 
library, what you need is in your Lazarus tree, bindings sources are 
located in lcl/interfaces/qt5/cbindings , to build it just follow 
README.txt."



Now I tried installing the packaged libqt5pas and still see no segfault.
Note that this isn't a fresh install, I dist-upgraded it (or better 
do-release-upgraded it) many times, but I don't think that should matter.

Thank you very much for maintaining OPM! And feel absolutely free to ask
any question about the package if you need. 

I have a naive suggestion for OPM. Some components depends on external
libraries/binaries (libffi, openssl, libsagui etc.), so it would be nice
any field like "Libraries", or "Dependencies", or even "External files"
inside the "Package info", providing previous information that the package
needs external libraries/files to work properly. (sorry if it is already
implemented, I'm using Lazarus 2.0.6)

New applications have to use Brook Tardigrade, available at
risoflora/brookframework  (with
a branch for minor changes: risoflora/brookframework/tree/v5.1
). The OPM is
supposed to provide it, named as "Brook Framework".

The old version is available at risoflora/brookfreepascal
, however, it is not
maintained so often.

Hi Michael,

When I scroll the Online Package manager list of packages with the trackpad

Anyone else having this behaviour ?

Alternatively you can also use incremental search in the package tree.

The Message Window is not obscured by OPM, usually I check the error

Duh !  I should have checked that... 
The message window was obscured in my case. 
Damn this docked IDE, I can't get used to it ;-)




Ideally you shouldn't see any error messages :), however there are too many
Lazarus/FPC version/widgetsets. I cannot check each package on every single
platform. This should be the package maintainers job.
In Lazarus trunk there is a small improvement though, if a package is not
tested against a specific widgetset/Laz/FPC version, OPM will warn you,
that the package compile might fail.


OK, seems like a good idea.

BTW, the message was not meant to point out that there is a broken package.
I understand perfectly you cannot check every possible package out there.
I simply didn't see the messages window.

for completeness sake, here is the actual error:

brookfclfcgibroker.pas(23,12) Fatal: Cannot find CustFCGI used by 
BrookFCLFCGIBroker of package BrookRT.




Or must I open the package manually, compile manually to see the error ?

If so, why isn't there a 'open this package' entry in the list of packages
?


This is a good idea, I can add an "open this package" entry.


Yes, please. That would be really handy ! See below.



have no easy way of locating the package.

In the options, I found where the OLPM downloads the packages,
but to get there on a mac involves an insane amount of clicking,

Please click the "Local Repo" button(see attachment) , it will open a file
manager window with the folder where the packages are installed.


Yes, I did that before mailing.

But when I open a package in this dialog, it shows me an empty file list :(

So, in order to open the package, I must then
* remember the location
* close this dialog and go to the 'open package file' dialog in the package 
menu.
* Browse to home directory.
* Enable showing hidden files with Cmd-Shift-Period to be able to select the 
.lazarus
directory (this is Mac!)
* Continue to correct directory
* Open package file.
And then I see the correct file list in the package...

Now you will understand why I think the 'open this package' entry is a good 
idea ;-)

Thanks for looking at this :-)

No need to create indexes or dropping indexes or changing fields of an

fact changes the fields of index ''). and if you set  IndexFieldNames to 
blank it restores the original table order.


That make of TbufDataset a useful component, not a nightmare. It needs

indexes. You may get "The maximum amount of indexes is reached."


By the way. I got "The maximum amount of indexes is reached." and I went 
mad trying to find where I was creating two indexes. Was I calling 
addindex twices before and I wasn't aware?. Finally I looked at the code 
and when you call addindex, it creates two indexes: 'DEFAULT_ORDER' and 
''. What are those two phantom indexes for? I couldn't find any 
documentation about

Re: [Lazarus] Checkbox behaviour on Mac ?

[Michael Van Canneyt via lazarus]

As I said, a stock Lazarus 2.0.6 install. From the about dialog, it seems to
be using carbon.

[Lazarus] Online Package Manager list behaviour

[Michael Van Canneyt via lazarus]

Hi,

On a mac, lazarus 2.0.6:
When I scroll the Online Package manager list of packages with the trackpad
of the mac, then the list scrolls a couple of items and then jumps back to
the item that was displayed initially. 
So it is impossible to scroll. e..g. to the end of the list.


If I use the scrollbar at the right, then it works as expected and I can
scroll to the end of the list.

Anyone else having this behaviour ?

Michael.

[Lazarus] Online Package Manager errors ?

[Michael Van Canneyt via lazarus]

Hi,

I tried to install a package using the package manager (Brook framework).
The package manager tells me the compile failed.

How can I see what the actual error is ?

Or must I open the package manually, compile manually to see the error ?

If so, why isn't there a 'open this package' entry in the list of packages ?

I have no easy way of locating the package. 
In the options, I found where the OLPM downloads the packages, 
but to get there on a mac involves an insane amount of clicking, 
provided I managed to remember the location where the package is supposed to

be...

A browser's 'downloads' window allows you to open the file or open the file
location. I think this could be a good addition to the OLPM.


Michael.

When you close the TBufferDataset, all the data is cleaned.


Correct.



TbufferDataset has a MaxIndexesCount that limits the number of indexes. 
By default this property is intialized to 2, and two indexes are created 
and used by default as soon as you call addIndex. So you must call 
addIndex before opening the table, or set MaxIndexesCount to at least 3 
in order to be able to add an index with the table active. (you can't 
close the table to add new index or you'll lost data).


Correct.



There is no way to drop a single index, and there is no way to change 
the index fields on the fly, you must call clearIndexes. And to call 
clearIndexes, before you must close the dataset, and so loose data. Am I 
right?


Yes.

So, if I want to process the dataset in different orders with 
TbufferDataset, before opening the dataset I must set MaxIndexesCount to 
all the orders I'm going to use.


Yes.



Am I right? Or I have missed something?


You are right.

Probably we should at least now offer the possibility to delete indexes, and
I am not sure the MaxIndexesCount is still needed.


By the way, What does the index option "ixNonMaintained" mean?


I don't think it is used in FPC, I think it's a Delphi compatibility option.

Hi Luca!
I have now solved this problem by installing the MATE desktop handler
in my Ubuntu 18.04 laptop!
https://itsfoss.com/install-mate-desktop-ubuntu/

After it was done I now have a much more useful environment (in my
view as a programmer in any case) and there is no more
minimize/restore problem. It works exactly as in Windows and Raspbian
Buster concerning the window handling.

So I did not have to start over altogether but can still keep what I
have done so far.

[Lazarus] Online Package Manager question

[Michael Van Canneyt via lazarus]

Hi,

How can one include a new package in the Online Package Manager repository ?

on

https://wiki.freepascal.org/Online_Package_Manager

There is somewhere

'Upload somewhere the files and send the link to getm...@gmail.com or
press the submit button, the files are directly uploaded to a remote
server.'

Is this still the official procedure ?

Michael.

[Lazarus] Is there a demo for SHDocVw_1_1_TLBP.lpk

[frans via lazarus]

Hi,

I'm using Lazarus 2.04 on Windows10.
I've used the shdocvw_1_1_tlb.pas unit (imported on 2-1-2016 from 
C:\Windows\SysWOW64\shdocvw.dll) to show helptext in a browser. Now 
there is a new package ActiveXInternetExplorer and the contents of 
shdocvw_1_1_tlb.pas (imported on 23-7-2017 from 
C:\Windows\System32\ieframe.dll) is very much different from the older one.
I've tried to figure out how to use this new pakage, but I don't 
understand it and I can't find any documentation. Is there someone who 
can explain this to me? Or show it to me in a little demo?


Thx very much.
