I hope it is more clear now. Regards, Ara The easy one is probably to make two independent connections to the database. More elaborated solutions would be for example copy all said records to a memdataset and only connect that to a dbgrid, OR put the records in a non-dataset enabled component, like a TDrawGrid or TStringGrid, browsing that will not trigger any dataset events so other db controls will be unaffected, etc. The problem here is I think synchronizing stuff, you will have a funny time getting the updates to those records into the original source.

I want to scroll the grid and get new data without changing RecNo. In your example if I only got 9 record for example but I want for example 20th record. Not sure if I understand the part on "moving the query", but using TDataset derived components, and without using the basic MoveBy, Locate, first, last, next or prev you can't. Some dataset descendants may have some properties that help at some cost, for example y you set PacketRecords:=-1 then sqldb will load all the records and in this case RecordCount may be reliable, that is if dataset is not filtered (or that seems to indicate the relevant documentation). Some datasets may actually return a valid record count, probably TDbf is in this case. In any case without using the mentioned basic operations you can't select records.

I mean if I want to make a custom grid simple solution si going from first to last of TDataset and read columns value. I Browsed TDBGrid code lately but sadly I couldnt find how it works to get data without (as I think) browsing and changing TDataset records. Regards, Ara --http://www.fastmail.com - Send your email first class DBGrid does not read all records from first to last in order to show them, it only "specify" how many records it can show at the same time, it does this using a data link, TComponentDatalink, which is just a TDatalink with some custom dataset events for easy hooking, a data link is an intermediary between the grid and the dataset. So once the amount of records is set, the grid uses a datalink property: ActiveRecord in order to select which record from the ones it has reserved is the active record, then DbGrid maps this active record to the grid.Row property, the grid.Col property is mapped to a field index and using the standard dataset properties like Fields[i] or the field associated to a column which is again just taken from the dataset. The dataset is in charge all the time in keeping the reserved records up to date, the grid just shows the values it finds in the records. The starting point when the records are shown in DbGrid is procedure TCustomDBGrid.DrawAllRows; there the ActiveRecord is selected, DrawAllRows eventually ends calling individual cells for each row which does DefaultDrawCell and several others. In bug report http://bugs.freepascal.org/view.php?id=29764 I put an example of using TDatalink with multiple records and without DbGrid in a console program. Hope that helps.

And it converts it to whatever DefaultSystemCodePage says it should. Now this is a problem because in Windows and according to the wiki this value is "The result of the GetACP OS call, which returns the Windows ANSI code page". In my case, and I guess Silvio's too, DefaultSystemCodePage=1252 not CP_UTF8, so in our case if AText is 'Greek: Γειά σου κόσμος' there will be problems converting that to CodePage=1252 which is solved by showing the "?" in the problematic characters the SetMultiByteConversionCodePage(CP_UTF8) call makes DefaultSystemCodePage=CP_UTF8 which matches UTF8String and so in fpc_ansistr_to_ansistr no conversion is performed.

Mainly because the existing ones written in Object Pascal suffer from several disadvantages: - Font support usually incomplete or downright buggy. - Dependency on a GUI (LCL, VCL, Windows). The latter is important because the PDFs must be generated on a headless (no display) webserver. So, the fcl-pdf package contains a PDF generating unit fppdf that does not depend on any external libraries or GUI system. The PDF generator has the following features: - Support for basic shapes. - Support for basic line styles. - Dictionary support. - Multi-page PDF. - Image support. - TTF Font support. - Font embedding. - Unicode font support. - Stream Compression. - Image embedding. - Several paper types. - Portrait/Landscape. - Support for multiple measurement units. - Rotation matrix system. - PDF creator information. - The generated PDF passes several PDF validators. The library is based on a library that came with FPGUI, with a feature set which came closest to what I desired. It was completed for the company I work for by Graeme Geldenhuys, and is heavily unit tested. It is not yet feature-complete, but the above should be ample for most applications. In the near future, I expect to commit a reporting engine which, likewise, does not need a GUI (but can use one) and uses the PDF generator as one possible backend. Todo: - Implement TFPCustomCanvas descendent (TPDFCanvas) that draws on a PDF. (should allow easy integration in LCL) - Partial embedding of (unicode) fonts (only used glyphs) for smaller PDFs. - On windows (possibly mac), allow to use native font mechanisms for extracting info from TTF files. - Reduce memory usage by streaming finished pages to file.

I have actually fixed the problem, but in my current implementation resources are only be freed at program end. Which is not good if somebody are printing a lot. So I have not committed the fix, I have another plan and will try again soon. In the mean time, the workaround it's easy (this is not the fix I mentioned before which would patch the LCL+Printer support). Just create the bitmap before Print.BeginDoc and free it after Print.EndDoc. That should work.

In the context of a report, they are the same thing to me. You define a variable via the Report GUI Designer (I still don't know how to do it from code), that variable is then available for use anywhere in your report. ie: gloabal ;-) :) Yes, you can consider them as global if you so desire. However they exists only in your report, where they were defined. The frVariables list however can be used by n-number of reports in your application. This is why I think of them as "global" I think the easier way to modify global variables is through the frVariables object ej. frVariables['HideKlas'] := 1; I'll take a look at that, thanks. 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 mean 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.

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

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.

Re: [Lazarus] patch for lazreport (TfrPictureView.getBlob)
Because you are getting the image data from a different source than the dataset
itself, traditionally you do this in the event OnEnterRect which exists for
this kind of situations, see for an example the Thumbnails Report in the
lazreport/samples/editor sample, I quote here the relevant part:
procedure TfrmMain.TheReportEnterRect(Memo: TStringList; View: TfrView);
begin
if (FImageList<>nil) and (View.Name='thumbnail') then begin
TFrPictureView(View).Picture.LoadFromFile(FImageList[FImageListIndex]);
Inc(FImageListIndex);
end;
end;
In your case you could probably do something like this:
if View is TfrPictureView then begin
TfrPictureView(View).Picture.LoadFromFile(
'test' + myQuery.FieldByName('Test_Int').asString+'.bmp')
end;
Which looks more simply than your proposed solution.

Re: [Lazarus] LazReport: TfrReport.LoadFromFile question
Please file a bug report, at least the unexistant .lrf case should trigger an exception. Jesus Reyes A. El Domingo, 24 de agosto, 2014 16:56:44, Bart escribió: 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)?

The problem here is sqldb bookmark handling on detail datasets. In some circumstances it's broken, see bug reports http://bugs.freepascal.org/view.php?id=26132 and http://bugs.freepascal.org/view.php?id=26146 LazReport backup datasets current positions before the report is processed and then it tries to restore them when done. It does this because sometimes the datasets are linked to visual components which, in the end, would show incorrect "current" records. The implemented solution is by using a notification, when LazReport is about to backup the bookmarks, it triggers an event which on return instruct LazReport to do the backup/restore bookmark action or not. If "not backup/restore bookmarks" is (most of the time) the expected behavior, we can replace the current solution and implement a LazReport option, roDontBackupBookmarks enabled by default. So it doesnt backup/restore the bookmarks automatically. Suggestions are welcomed.

Another way is, as shown in UserDs example, using a Script, You can make a
script var 'Negative', which value is updated in OnGetValue, just like
FNegative below, the difference would be that 'Negative' is a script var and in
your example FNegative is some data module field or property. In the UserDS
sample that would be something similar to variable 'I', for example.

Used that way, the memo field's script would be something like:
Begin
if Negative then
FillColor := clRed
else
FillColor := clWhite;
End

Re: [Lazarus] clicking a dbgrid's column title does not trigger OnEnter event as with Delphi
One reason would be that Lazarus DbGrid it's not a Delphi DbGrid clone. Without more information one can only speculate: OnEnter should be triggered in case the grid has not the focus, if it already has the focus, I don't see why OnEnter should be triggered on column click. If you explain what you want to do, probably somebody could give you some alternative. Jesus Reyes A.

To not repeat myself please read my note in http://bugs.freepascal.org/view.php?id=24059 I have been a little busy and the fix for carbon was delayed because it seemed to me that it will be a better fix to handle this in LCL package using build macros, defining globally a conditional, HAS_INHERITED_INSERTITEM for example, if fpc version is less than 2.7.1 (it is needed at least for Carbon and Qt (and possible gtk2 too according to issue 0024154)). If that is not a viable solution, I can fix it the same way than for Qt.

How to they all differ? goEditing: makes the grid editable or not (some will say it's equivalent to a readonly property) goAlwaysShowEditor: if the grid is editable as its name say it will make the editor always visible, no effect if the grid is not editable. as for AutoEdit, normally if the grid is editable clicking a selected cell will popup the cell editor, that's for AutoEdit=true and is what delphi stringgrid does, if you set AutoEdit=false editor will not pop up on clicking a selected cell, I forgot the reason this was added but as the Lazarus stringgrid allows range selection on editable grids, this may help in this case.

The problem with SaveOptions is that it's supposed to apply only to Save/LoadFromFile (I wish to have named SaveToCSVFile as ExportToCSVFile instead) visibility on CustomColumns should be preserved on saving/loading to/from a XML file (that by the way is missing), but it's ok to export only visble columns to CSV file. So what about adding yet another parameter to CSV functions?, Even, if more features continue to be added to CSV support, it may be better to move the whole CSV support out of grids unit and create a component or something.

>I have two stringgrids with exactly the same columns, basically something like >Excel autofilter. >Does anybody have an idea how to change the scrollposition of a stringgrid >depending on the scrollpos of the other? One way would be using OnSelection event and try something like: sg1.LeftCol := sg2.LeftCol; sg1.TopRow:=sg2.TopRow; sg1 will be synchronized to sg2. That would give you row/col size granularity. For pixel granularity, without messing with grids internals, could be done using GetScrollInfo for both scrollbars on source grid and using SetScrollInfo for both scrollbars on target grid.

[]s Daniel Conheça o Projeto ACBr - Automaçao Comercial Brasil DJSystem a Loja Patrocinadora do ACBr Since r36041 all stretchable objects that have stretched property enabled are unconditionally stretched (fix for issue 20988) and that included line objects which were always implicitly stretched, however line objects didn't have a published stretched property and they were always treated as if the stretched flag was set. That produced the extra long vertical lines seen in the screen shot. There are two ways to fix the problem, either turn off stretched property on master data band, so all stretchable objects are not stretched, or update to r36497 or newer and set stretched=false on all line objects, this is easy to do by using the bonus feature "Select same class objects". It works by doing this: -Select one line object -Right click the selection-Click the "Select same class objects" item once all line objects are selected -right click on selection and uncheck "stretched" propertyor-press F11 and change stretched property to false.

Delphi grids do not implement a clear method :D so this is not a compatibility problem, or is it?. The add-on component VirtualStringView/Tree does implment a clear method that does not delete the headers. Lazarus grids never meant to be compatible with virtualstringview/tree.

Well I don't in this case as Delphi grids do not implement a clear method :D so this is not a compatibility problem, or is it?. IIRC the problem you had with clear method is that after the clear you wanted the grid remembered your (fixed)cols/(fixed)rows layout. That was not planned for a cleared grid, because AFAIK, clear means dump everything, for example for a listbox means remove the items, not empty the items, then why should it remember it? however it seemed a good to have feature and I implemented it. However, now you seem to suggest that calling clear should only mean clear the non fixed cells?, in this situation, if somebody has a grid with 2 fixed rows and 1 fixed column which was setup at design time with right titles, what should happen on grid.clear?, delete columns or rows? or just the non-fixed cells? At least I never seen a grid with just fixed cols/rows and no normal cells. That is why "clear" is supposed to remove cols/rows and "clean" only cell content. Before anything, Delphi grids do not implement (that I know) a clean method, so this is not (or, not everything is) a compatibility problem :D > > Adding optional parameter "AClearFixed: Boolean = true" to > Clear > may help without comprimising compatibility That would solve a nonexistent problem, no need to implement something to remedy it. > > -- > Alexander S.

Me neither ... I use Run rarely .. prefer debugging from console :)
So must used by me is Compile (I use Build when I touch some of my packages or
changed lazarus production version).
zeljko
For me "Run" is the menu where "Compile" commands are. Menus are most of time
accessed by mouse, and for that "Run" commands on main toolbar are accessed
quickly, but there are no "Compile" commands on toolbar (hint).
Given that many people see the "Run" menu where "Compile" commands are, I
wonder if we should rename it to "Compile", or even doing some justice to
"Compile & Run" ;)

This is delphi compatible. IMO Then we need to define clearly what is our goal, are we (by default) trying to replicate delphi menu layout?, if yes then we can talk about "compatibility" and lets change the whole layout once for all so we can start getting used to it, if not, then this is non sense. If the argument is better functionality then go for it, but in absence of better arguments I prefer to not move the menu layout until some mechanism for personalization is invented and integrated by default.

Having "source" and "refactor" menus is IMO too much, why not insert Refactor menu as a submenu of Source menu. Taking a look at the sub-menus refactor menu offer, most useful actions are the first three, which can be invoked by shortcut (and that is probably what everybody does while editing the code). So why it needs such prominent place in Main menu? Another drawback is that refactor translates to refactorización in spanish, too long word and when you don't have a wide monitor or simply don't want IDE main form maximized, every pixel counts. > > Eclipse has Source menu but otherwise I would not follow > many or their > inventions.

Re: [Lazarus] LazReport troubles
--- El mar 7-dic-10, Alexander du Plessis escribió: De: Alexander du Plessis Asunto: [Lazarus] LazReport troubles A: "Lazarus Mailing list" Fecha: martes, 7 de diciembre de 2010, 23:53 I recently upgraded my Lazarus to 27041. I have an application using LazReport. The application worked fine before the upgrade and showed the Preview of the report to perfection. Since the upgrade, It only flashes the message box that it is preparing the report and no Preview is forthcoming, It just does not exist or is completely invisible. When using the report designer, and one calls the preview via the designer, the report preview is visible with data etc. I run Lazarus/FPC on a XP box. 27041it is already old, and there have been many changes in lazreport since then My problem is thus: When calling the report preview from code, I get nothing. When calling the preview via the designer it is visible and correct. strange... Would my problems magically disappear if I upgrade to a later svn version or is there other problems related to this matter? just try one snapshot on a different Lazarus directory, if problem persist and you want to be sure your project runs fine in the upcoming 0.9.30 release, please submit a bug report with information how to reproduce the problem. Kind regards. Alex du Plessis Jesus Reyes A. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
