Yes. At some point, the published properties of objects started to
become available in scripts. It appears that 1.2 version already
included that functionality, probably there were some bugs that
prevented resolving the 'name' property properly in 1.2 but was fixed
later in the 1.4 version.

The finished report can be saved to JSON file. 
It can be rendered to a printer canvas.

But you can also make a utility that prints this file to a label-printer.



Also, will users still be able to design their own reports like they can with 
LazReport?


Yes, obviously.

Well - good luck - Lazreport took a long time to get stable and 
certainly contains many idiosyncrasies that could benefit from a 
redesign. But please ensure that there is a clear migration path to any

The primary save format will be JSON, which can be converted to anything you 
want.
We're not making any assumptions about the final output. 
The structure will be such that adding exports should not be a problem.

We have at least PDF planned, for use in Web applications.

In fact, FPC's TTF/PDF support is being worked on as I write this.

[Lazarus] LazReport - Feature questions

[Gabor Boros]

Hi All,

Earlier I think will use LazReport for my new project. Implemented Child 
feature for my needs but now see many other lack of features, problems, 
reported bugs.


Features for example...
- Page, Band not have Frames and FillColor properties
- FillColor not have (Brush.Style) property
- Stretched not working with Line
- Frames not have Color, Style, Width properties/side
- Keep together feature for Band (e.g. Parent and Child(s))
- In Designer Text object not resized when Font changed
- On Preview can scroll below the page
- On Preview Find highlight the whole text of view and only the first 
occurence

- Barcode not have Font property

Reported bugs for example...
http://bugs.freepascal.org/view.php?id=19996
http://bugs.freepascal.org/view.php?id=26263

How easy or hard or impossible to implement the above features into 
LazReport? In the main source not in a fork. Seeing the above features 
from LazReport POV better for me if create a report engine from scratch 
which fit my needs? Opinions?

Digging deeper into the LazReport code, I finally found the solution.

Even though you setup a variable, you must not refer to it via the
Scripts.Values[] or Variables.Values[] properties. Go figure!

Instead you use the Values.FindVariables() method.

  FRPrint.Values.FindVariable('HideKlas').Field := '1';



Those are not global variables. They are report variables.

I think the easier way to modify global variables is through the  
frVariables object

ej.

frVariables['HideKlas'] := 1;




For more details of what I've done, see the Lazarus Forum post.
  http://forum.lazarus.freepascal.org/index.php/topic,28922.0.html


Now this begs the question... What the hell does Scripts.Values[] and
Variables.Values[] actually do?


They do the same thing they do for any TStrings list, ie. Assign values to  
supposedly existing names , for they to work you have to have a list  
like:


name1=value1
name2=value2
etc.

But in LazReport this TStrings list functionality is not used.

Report.Variables holds the list of variables and variables categories that  
you have defined in the Report (usually using the report designer gui).  
Variables categories can only be used as distinctive tags for a group of  
variables, and I guess that is the reason why there are a Values object  
too, which btw has a list of only variables.


I was not able to find a Report.Scripts property or field, maybe you mean  
Report.Script? in that case supposedly it holds the script to be run as  
BeforePrint script.

Yes, you can consider them as global if you so desire. However they exists

It seems possible to have report and global variables named the same,  
however I have not investigated who takes precedence, I would guess report  
variables are found first, but I'm not sure TBH.






But in LazReport this TStrings list functionality is not used.


Huh? You lot me there. So if they are not used, why do those properties
still exist in TfrReport?


They are not specific to LazReport, this is basic functionality of every  
TStringList, just because they descend from TStrings. Values and Names are  
public properties of TStrings, how can one hide those properties in a  
instance of TStringList?, you can't, so LazReport also can't. :D





I was not able to find a Report.Scripts property or field, maybe you

Report.Script?


Sorry, it was a typo. I meant Report.Script.

As far as I understand, LazReport is based on some open source version
of FastReport. Due to the lack of documentation (or updated
documentation) of LazReport, I looked at the documentation for
FastReport and tried to use some if what it suggests. But it seems much
of it doesn't translate to LazReport.


Yes, probably, however one could find that they have also many things on  
common.




Here is the URL of FastReport I looked at.

https://www.fast-report.com/documentation/ProgMan/index.html?adding_a_variable.htm

I worked through the whole Working with a list of variables section.



frxReport1.Variables['My Variable 1'] := 10; and likewise
Variable := frxReport1.Variables.Add and
Variable := frxReport1.Variables.Insert(1);

Wouldn't work on LazReport as here frxReport1.Variables is just a mere  
mortal TStringList which already have a default property: Strings[]  
indexed by integer, This part is in LazReport a little mess :), I think  
FastReport guys noted this and they fixed the situation in FastReport.

[Lazarus] lazreport: how to use global report variables

[Graeme Geldenhuys]

Hi,

I have a print dialog, shown before the report is generated. The user
can make some selections. Based on that, I want to set the value of a
global variable, then use that variable to decide if a column of data
must be visible or not.

I've used File - Variable List to define a new variable (just the name).

I then double clicked on a header memo field and enabled the Script
checkbox, and typed in the following code in the Script box:

===
if [ HideKlas] = '0' then
  Visible := True
else
  Visible := False;
===

In my *.pas unit I temporarily tried to set a hard-coded value of the
HideKlas variable to see what happens in the report. I tried both the
values '0' and '1'.

===
If FRPrint.PrepareReport then
begin
  FRPrint.Variables.Values['HideKlas'] := '1';  // for testing only
  FRPrint.Preview := FAfdrukForm.PrintPanel;
  FRPrint.ShowPreparedReport;
end;
===


No matter what I do, the header (memo) field is now _always hidden_.
Changing the hard-coded value of the variable doesn't seem to make any
difference.

Before any of the above script changes the report worked, and the header
text was visible. But I can't seem to make that visibility a dynamic option.

Any tips would be much appreciated.


Regards,
  - Graeme -

I've even tried removing the HideKlas variable completely, then do
something like this in the .pas unit.

  (FRPrint.Pages.Pages[0].FindObject('memo5') as TfrMemoView).Visible :=
False;
  FRPrint.Preview := FAfdrukForm.PrintPanel;
  FRPrint.ShowPreparedReport;

But not even that works. In this case the memo5 is always shown, as if I
didn't have that extra line of code.

Is not possible in current implementation. Name or Position (x,y) have no

It even seems that as soon a subreport is found any remaining object is

Not in the current implementation.



3:
Deleting an object from a report (memo / band / subreport) will often

I haven't yet been able to conclude precisely what its related to, but

Is this at all possible ?

2:
All objects seem to be accessed in the order they are saved in the lrf 
file, not by Name (alpha) or position - this makes it problematic when 
using them for calculations.
Is it possible to have the running report fill in the fields by alpha 
name position instead ?


3:
Deleting an object from a report (memo / band / subreport) will often 
cause the program to abort.
I haven't yet been able to conclude precisely what its related to, but 
still watching.

Does anybody else have this issue ?

Many thanks

Hi,

TfrReport.LoadFromFile does not raise an exception (or return ay other
indication of error) if the file does not exist and the filename has
the .lrf extension.
If the filename has another extension the code results in a dialog
'Unsupported FRF format'.
This to me is even more bothersome, I cannot trap this in code at all,
nor can I suppress the dialog.

Similar to other components that have a LoadFromFile (TMemo, TSynEdit,
TStringGrid to name a few), I would expect the LoadFromFile to raise
an exception in both cases.

Before I file this in the bigtracjker, I ask here.
Maybe this is by design (compatibility with Delphi perhaps)?

Re: [Lazarus] LazReport - access violation

UPDATE  This only seems to happen when some records have a large entry in the 
memo field.  The problem seems to be with the routine that calculates the field 
size but I don't know how to fix it.

(This refers to LazReport crashing when a memo field is included in a report)

The postgresql installer will also install the Visual C++

Yes. Use e.g. -gw2 -gl -O-1 (Lazarus: dwarf 2 format, line number, no

compiling.
Run gdb as usual and you should get the backtrace or run it in the

That's with Lazarus 1.2.2, on Linux 64bit. But I think I do have the 
same problem on 32bit Windows. I switched to linux to be able to 
backtrace. Can I have a backtrace in Windows ?

Yes. Use e.g. -gw2 -gl -O-1 (Lazarus: dwarf 2 format, line number, no
optimization, add -O-1 in extra options or whatever it's called) when
compiling.
Run gdb as usual and you should get the backtrace or run it in the
debugger under Lazarus to do things the GUI way ;)

At least in other reporting solutions, master details means having some
master band, then a detail band below it.
This gives the following setup:
Master1 record
...detail1:record1
...detail1:record2
...
...detail1.recordn
Master2 record
...detail2:record1
...
...detail2:recordn1

In other words, it supports single row reports only.
No idea if this applies to lazreport.


This works fine in Lazreport, but it's not what I want. I want all data, 
including details, of the master-record on one line.




In other reporting solutions, if you want to have master+detail info
next to each other, you can use a query in the database that provides
the info in the desired layout.

This is often known as s acrosstab query, searching gives e.g.
Postgresql
http://stackoverflow.com/questions/3002499/postgresql-crosstab-query
Or
http://www.paragoncorporation.com/ArticleDetail.aspx?ArticleID=25

Obviously no idea if this applies to lazreport as well.


This should work in Lazreport, but that's just a case of a masterband.

The point is then : what's the cross-data band used for ? How does it work ?

Anyway, thanks for your input.
B.T.W. I'm using Firebird as a database.

Re: [Lazarus] Lazreport master-detail on one line

[Giuliano Colla]

Il 26/05/2014 13:26, Koenraad Lelong ha scritto:

Hi,

I want to make a report of database data. The data has a master-detail 
relationship. For every master-record there are a fixed number of 
detail-records.

A detail record = ItemCode, ItemValue

So I make a lazreport. I put a masterheader band on the report and I 
put some text on it. Then I put a masterdata band on the report and I 
put some rectangle objects on that band and connect those the 
master-table. When I show the report, everything is like I want it.
Next step is to add detail-fields. I though that using a cross-data 
band was the needed tool. On the crossing of the masterheader-band I 
put a rectangle-object and couple this to the detail-field ItemCode.
On the crossing of the masterdata-band I put a rectangle-object 
coupled to the detail-field ItemValue.


When I now show the report, my master-information is OK, for all 
master-records, but the detail-information is that of the first 
detail-record, for all master-records. Also the information of the 
detail in the master-header is OK.
I have two grids showing the master-detail information so I know my 
queries are OK.


What am I doing wrong ?
Enclosed a screenshot. Green ovals contain correct data, the red oval 
contains bad data.


It would appear that your detail-field always points to the first item 
of your query. Which is not unexpected, because, most likely your detail 
fields come from a different query than that of the master fields. 
Master query automatically increment at each line, other data do not.
If such is the case, you should take care of filling up your detail 
fields programmatically, using variables instead of query fields in your 
form, and taking advantage of a frWhateverGetValue, returning a ParValue 
taken from your query. Sort of:


procedure TMyForm.frWhateverGetValue(const ParName: String;
  var ParValue: Variant);
.

if ParName = 'SA1' then ParValue := SQLQueryXX.FieldByName('SA1').AsInteger
else if ParName = ...


and, for the last parameter of the line, incrementing to next line of 
your query. Sort of:


else if ParName = 'LASTParam' then begin
  ParValue := SQLQueryXX.FieldByName('LASTParamName').AsWhatever;
  SQLQueryXX.Next;
  end;

Of course this works fine if there's a one-to-one correspondence between 
master and detail query lines. Otherwise your code must be a little more 
elaborated.


Hope that it helps,

Giuliano

[Lazarus] LazReport - access violation

[Alejandro Gonzalo]

I am using Laz 1.2 for Win32, with Advantage 
(http://devzone.advantagedatabase.com) for the database, Foxpro CDX format.
Everything seems to go ok designing a report with LazReport until I include a 
memo field, then it crashes.
Is there something special I have to do in LazReport to use a Foxpro style memo 
field?

Thanks

Hi,

With a new project, last week I tried to do this again. First with 
Lazarus 1.08, today with Lazarus 1.2 (downloaded and installed this 
morning). Still the same problem.
I looked in the bugtracker. There is a request for a new sample-project. 
Unfortunately I lost my password and the email-address is not valid anymore.

The bugtracker states :

You need to first link TfrDBDataSet to a TDbf (which could be in a TDatamodule) 
and then link the TfrDBDataSet to the TfrReport via the Dataset property.
When you use the query on the same form as the report, this is *not* 
needed. And adding a TfrDBDataSet and connecting it to the query on the 
datamodule does not work.


FWIW, I'm running WinXP.
I do have a new project with the mentioned TfrDBDataSet. Can I upload it 
here ?


Koenraad.

In your report you wrote that setting up the connection in code works, that 
means it's a problem at runtime, the response in note 72299 address the problem 
in that case, and as it written it works if you link TfrDbDataset etc. 

But now things are clearer as you say the problem is at design time, and yes, 
the issue can be reproduced. The problem here is LazReport (in form1) can't get 
an instance to Datamodule1.Dbf1 at Lazarus design time. At design time, the 
object inspector knows how to get an instance to a component residing in a 
external form/datamodule but LazReport designer at Lazarus design time doesn't 
know.

This is basically to Mattias, is it possible to register at design time data

You can use the Report.ExportFileName field for selecting the default file name 
the dialog will use on exporting. In addition, passing a filename with

Setting the initial directory was not implemented, is now in r43471, the file

Hi Giuliano,

As you may know, the patch was merged to fixes but, a problem was detected, it 
introduced a regression, please see http://bugs.freepascal.org/view.php?id=23901

Jesus Reyes A.


I made further tests both under Linux and under Windows. The behavior 
turns out to be the same.


What happens is that my patch (i.e. setting Band name from the BandView) 
doesn't affect Preview at design time, doesn't affect any method for 
displaying a Report (PrepareReport, etc.) but it causes an error if you 
attempt to design a report in runtime (something I had not tested, 
because I didn't use it) .
In that condition (and only in that condition) whenever the name of an 
object is set, it verifies if the name is duplicated. As we have the 
same name for BandView and Band, when we set the name of the Band it 
triggers the error.
It's unclear to me while this test is made only in this condition, 
because there should be no difference if you design a report at design 
time, or at run time, but that's how it's made.

[Lazarus] LazReport Band.name patch

[Giuliano Colla]

While implementing an application which uses LazReport, trying to take 
advantage of OnBeginBand I discovered that Band.Name is never set and is 
left as an empty string.
This can be annoying if you have more than one Band of the same type, so 
that Band.Typ is not enough to tell the right band.
Here attached two patches which for me fixed the issue, one, an svn 
diff, for the svn version 2.4, and the other, a plain diff, for the 
current Lazarus release (1.0.4) version, i.e. 2.3.

Maybe it can be done much better, but just in case...

That's correct, TPostscriptCanvas do not support all unicode, Latin and 
Cyrillic should be fine though.
What about Arabic? Some fonts do not produce any Arabic output at all, 
and others produce detached characters (isolated form) only.

Yes, it doesn't export images. I think an option can be added to html exporter

That's correct.

There are at least two solutions, according to bug report 
http://bugs.freepascal.org/view.php?id=15161 using Qt interface should work. 
The other solution is exporting pages as images with Image Exporter, that I can 
confirm it does ok, see LazReport/source/addons/imgexport/lr_extexp.lpk

There is another possibility, for the future, time ago petr kristan made a 
CairoCanvas object that can be used instead of TPostscriptPrinterCanvas. After 
I fixed some things I made it work again but showing Chinese text and images 
was unsuccessful. It currently uses plain cairo to show text, I will try to 
improve it.

[Lazarus] LazReport Images and Unicode

[Giuliano Colla]

I'm trying to use LazReport to generate reports which should show an 
image (the company logo) and some Chinese text.

Currently (Lazarus 1.0.4 on Linux platform) I have the following scenario:

1) Report preview is correct (Image and Chinese text properly shown)

2) Report printout shows the Image, but skips Chinese characters.

3) Pdf export shows the image, but replaces Chinese characters with 
question marks. I understand that PowerPdf doesn't support Unicode, but 
changing the font encoding from Unicode to Big5 doesn't help.


4) Html export shows the Chinese characters, but doesn't show the image.

5) Text export shows the Chinese characters, but obviously doesn't show 
the image.


Is there a way to get a printout which properly reproduces the Report 
preview?


Can someone point me in the right direction?

[Lazarus] LazReport: printing on the next page, using stretch and breaked band

[Marcos Douglas]

Hi,

I have a table with a memo field.
I put a retangle with stretch property True; the band is stretch and
breaked property too.

The question:
If the info is bigger than a page, how the report can continue
printing in the next page?

[Lazarus] Lazreport and frf binary format

[patspiper]

Hi,

How can a binary .frf file be converted to lazreport's .lfr format?

Trying to open a binary .frf file yields an 'Unsupported FRF format' error.

[Lazarus] Lazreport compilation problems with FPC trunk

[Reinier Olislagers]

Hi list,

I reported problems compiling Lazreport with FPC trunk in bug 22527

I'm trying to look for the cause, but the output doesn't show much:
Compiling lr_progr.pas
...
C:\development\lazarus_fpctrunk\components\lazreport\source\lr_progr.pas(1,1)
Fatal: Compilation aborted

And a lot of Warning: Implicit string type conversion from AnsiString
to WideString in between.

How can I dig deeper to try and find out what's causing this? I've
looked at the compiler options for the package, Messages, but all
messages seem to be enabled...

Thanks,
Reinier

Figured out I overlooked the Compiler Options/Verbosity settings for
some reason.
Setting verbosity to -va and keeping the package options generate debug
info (-g) and line numbers (-gl) gives:

Hmmm? dbgstabs.pas suggests something to do with generating debug info
perhaps?

-va and no -g -gl does let Lazarus compile the package.

Perhaps the problem lies with the compiler instead of Lazreport?

Yes it is, compiler shouldn't crash.

[Lazarus] Lazreport preview always in fullscreen mode

[Alexsander Rosa]

Is there an option to set right before you call ShowReport() to avoid it
open in fullscreen mode?

[Lazarus] LazReport Database

[Koenraad Lelong]

Hi,

I was wondering if I found a bug in LazReport.
Like always, I put my database-components in a datamodule. Then I placed 
a frReport on a visible form. I started editing the report and I tried 
to place some database-fields on the report. Unfortunately, there were 
no fields available to place.


After experimenting for some time I found I had to place the dataset (or 
query) on the same form as the report. Then I can place database-fields 
on the report.


This is all at design-time. I didn't try this at run-time.

Is this an error or is this expected behaviour ?

Regards,

Koenraad Lelong.
