I know the lfm format is somewhat similar to pascal, but if such a

If the form is loaded in the IDE, there is an addon to store it
as Pascal code.

No entirely though. The Unix version is mostly a wrapper, yes - but the 
Windows version do some additional filtering:


function FileExistsUTF8(const Filename: string): boolean;
var
  Attr: Longint;
begin
  Attr := FileGetAttrUTF8(FileName);
  if Attr <> -1 then
    Result:= (Attr and FILE_ATTRIBUTE_DIRECTORY) = 0

Hence my question

[Lazarus] FileExistsUTF8() difference between Unix/Windows

[Torsten Bonde Christiansen via lazarus]

Is it a bug that FileExistsUTF8(...) reports true/false differently for 
folders in Unix and Windows.


On a unix platform (Mac/Linux tested) FileExistsUTF8() will return true 
to both folders and files


On windows platform FileExistsUTF8 will return true on files, but false 
on folders.

to this issue would like to hear other opinions. Here's what I wrote 
in bug tracker:


"I don't see anything wrong in the logics of the new behavior: The 
OnChanging event is fired before the selected node is changed. It has 
the node which will become the new selected node as a parameter, and 
you can do some validation and signal in AllowChange whether the 
change to the new node will be allowed or not. In the event handler 
you still have access to the currently selected node as 
TreeView.Selected. Therefore, there is no need at all to duplicate the 
currently selected node in the node parameter of the event.


This behavior is now compatible with Delphi (it was not before the fix).

Like any bugfix the new code breaks backward compatibility - sorry for 
the inconvenience if you have relied on the old behavior.


Which other controls have the OnChanging event? I only found 
TPageControl/TTabControl but they don't pass the changing tab as a 
parameter. "


I can understand the need for being Delphi compatible, but I'm not a fan 
of changing a behaviour (which IMHO is not a bug) like this which can 
potentially affect a lot of places in user code.

In a not to distant past multiple run-modes were introduced and this is

Now I wonder if it is (would be) possible to link the run modes with

would automatically start the program within Wine (without debugging 
naturally).


Is this already possible or should i add it as a feature request?

2) Using CTRL+Space on 1+ characters correctly brings up a list of

If it's too long you should use a TDrawGrid and paint the cells in

I forgot: Of course, this does not take into account the time it takes 
to populate the primary storage of the data shown in the DrawGrid. 
Filling a 2D-array with millions of strings, for example, will take 
its time too, 6 seconds on my PC for a 100.000 x 100 array. In these 
tests, the string is assembled as 'R' + IntToStr(rowindex) + 'C' + 
IntToStr(colIndex).
Yes, sorry for the lack of other factors too - those were just the two 
most needed.



I already have the data at hand in my own object structure so that is no 
problem. By fast i mean less than one second, even on a modern PC. The 
users of our program often have old or very old hardware in which case 
my/your 9 seconds turns to 30 or more seconds.


In reallity all i need is a read-only grid that can display the data in

[Lazarus] String Grid Component

[Torsten Bonde Christiansen via Lazarus]

Hi List.

I am looking for grid component that can display string. Simple enought 
and i know of a few already, but the ones i know of cannot do both of 
the following requirements i have:


a) Fast (very low delay on 100.000+ lines of test)
b) Allow selecting multiple cells spanning rows and colomns.

For a) i know of VirtualTreeview which handles large data very very 
fine. The problem is that is does not allow for selecting multiple 
columns and rows combined.


For b) there is the native LCL stringgrid, the lazarus package TKontrols 
is also good, but they don't handle large data very well. Mostly because 
all rows/columns are traversed (initialized) instead of the just the 
actual rows/columns displayed onscreen.


So i am asking if you know of a good string grid component that can 
handle both things equally well.


Kind regards,
Torsten.

Hi List.

I am reading some text of some .csv files, but the encoding of the files 
is not always the same. In fact it may vary greatly from a lot of 
european encodings, UTF8 and asian encoding.


I have tried using the function GuessEncoding(..) in LConvEncoding.pas, 
but from the source code I can see that it mostly focuses on BOM's and 
ASCII/UTF-8


Does Lazarus or FPC include other convinient tools that may detect the

My goal is to convert all the read text to UTF-8.

[Lazarus] Dropping files on TCustomEdit

Hi List.

In my application i have started testing dropping files onto the main 
form. Most of the components i am using on the form
happily accepts the file drops, but apparently this does not seem to be 
the case with any decendants of TCustomEdit (eg. TEdit, TMemo).


On the main form i have checked the property "AllowDropFiles" to true, 
and i've implemented a OnDropFiles method too. The procedure is
correctly activated when dropping files almost everywhere, just for the 
exceptions of TCustomEdits...


Is this considered a bug, a feature or do i need to do something special 
in regards to TCustomEdits?


My system:
Lazarus 1.9.0 r55954M FPC 3.0.0 x86_64-linux-gtk2

I have not tested if this is the case for Win32/64 too though...

E.g. if you out a button with Top=0 on an empty form and then add a menu, Top
stays at 0. So the offset of TChromium is wrong.

As a workaround you could change the position of the TChromium component (if
on Linux).
As I said, fpCEF on Linux embeds CEF into the XWindow of the main form, which
is more or less a borderless window manually positioned over the LCL form.
I tried with applying the height of the TMenu, but the GTK 
implementation seems to have a generic

value witch not truely corresponds to active DE and the style/font used...

I guess I will have to live with it the way it is for now.





In my project i create an HTML output for a statistical analysis program
and the code itself is very simple - tables and paragraph, and only very
little CSS.

It doesn't really matter what you show via TChromium, but how you use
TChromium.
And the tabbed browser is probably the most complex case and unfortunately
rather broken on Linux right now.

However, if you really only want to show very simple HTML, then
https://github.com/BerndGabriel/HtmlViewer
may possibly be the better choice for you.
The whole reason for using CEF was because the THhtmlViewer component is 
too slow! Especially in my case since I often work with
many and large tables (100 / 1000+ rows) which causes significal 
slowdows in that component.





In the OSR example the painting is tied to OpenGL IIRC, but can it be
tied to something else? and how?

Actually not. CEF only provides an array of pixel values, it is up to you to
do whatever you want.
Older versions of the OSRDemo used BGRABitmap:
https://github.com/dliw/fpCEF3/blob/5335a5ba437d469eb6f933e47ae0e0cd3d6e8968/Examples/OSRDemo/main.pas#L113


I will check that link out later and see if I can make the switch.





Another issue with all the versions of CEF i have tried so far is that I
get a SIGSEGV when closing any application that uses fpCEF. I have tried
many combinations when trying to shutdown, but it seems to boil down to
calling "CefCloseLibrary" that causes the SIGSEGV.

See the last part of my answer in this issue:
https://github.com/dliw/fpCEF3/issues/47#issuecomment-28195
I have already made sure to sync both the fpCEF and the CEF-minimal i 
can download, but i still get the problem.


For now i can make the call in a try .. except block and catch the error 
when closing down. That way the problem is only

visible during debugging. :)





In the meantime I have a version which implements the correct CEF shutdown
process. It works fine if there is only a single TChromium instance, but has
side effects when used in the tabbed browser. Focus get lost for all other
instances and there is no way to get it back, browser content turns black,
etc.
-> headaches...


So no good nows - sorry. It very much depends on CEF to improve the usage on
Linux.
If my testing can help you in anyway just say so. I'm no hardcore GTK 
coder, but i have a little experience so

I will try to see if I can assist you whenever possible.


Kind regards
Torsten.

Hi Torsten,


working with the framework is causing headaches

being the author of fpCEF, I can confirm that ;)


Is it correct, that you are using one of the latest versions of fpCEF on
Linux?
Absolutely correct. I'm using the currently available 3.3029 on Linux 
(64bit) GTK2



1) I need to hook into the scrollbars such that i manually can position
the view.

There is no API for that, but you can write JavaScript to do the job.
See the JavaScript example...

Okay - thanks.


2) Parts of the focus handling seems to be either broken or my
understanding of it is broken.

If you are on Linux, this is a known problem (for me; I need create an issue
on Github).

I myself use fpCEF for showing html pages (no interaction), so I only realized
it was broken, when doing the latest update.

The problem seems to be within CEF:
https://bitbucket.org/chromiumembedded/cef/issues/2026/multiple-major-keyboard-focus-issues-on

For GTK I think I found a way to work around the problem in fpCEF, but QT is
totally broken.
I'm trying to improve the current situation, but it will take some time.
In my project i create an HTML output for a statistical analysis program 
and the code itself is very simple - tables and paragraph, and only very 
little CSS.



3) Using the TChromium component does not paint the view correctly when
a main menu is used. There seems to be an offset problem.

Could you send a screenshot?


Without Main menu:




With main menu:
 - notice the lacking tabs, this is more prominent if not using a 
pagecontrol, but

   any other wincontrol to host the browser.

On Linux there are many ways to break TChromium. The reason is the way how CEF
is embedded into LCL. Currently CEF always is embedded directly into the
XWindow of the Form and positioned / resized via X events.
For simple use cases it usually works ok, but can break easily for more
complex setups (like the tabbed browser).
I already tried to embed CEF into the XWindow of the parent control of
TChromium, but then event handling breaks for CEF and the client LCL
application, if the parent is not a form.

CEF at the moment also does not support Xembed, which IMO could solve many
issues:
https://bitbucket.org/chromiumembedded/cef/issues/1417/linux-improve-cef-x11-window-behavior-in


The more robust solution on Linux ATM is the offscreen browser TChromiumOSR.
In the OSR example the painting is tied to OpenGL IIRC, but can it be 
tied to something else? and how?



Another issue with all the versions of CEF i have tried so far is that I 
get a SIGSEGV when closing any application that uses fpCEF. I have tried 
many combinations when trying to shutdown, but it seems to boil down to 
calling "CefCloseLibrary" that causes the SIGSEGV.

[Lazarus] fpCEF3 questions

Hi List.

I am trying to work with the Chromium Embedded Framework from 
(https://github.com/dliw/fpCEF3) and (http://wiki.freepascal.org/fpCEF3) 
but parts of working with the framework is causing headaches... :)


1) I need to hook into the scrollbars such that i manually can position 
the view.
2) Parts of the focus handling seems to be either broken or my 
understanding of it is broken.
3) Using the TChromium component does not paint the view correctly when

[Lazarus] Measuring text width in a TEdit

[Torsten Bonde Christiansen via Lazarus]

Hi List.

I want to know the placement of the caret (in pixels, not character 
count) in a TEdit. However i am struggeling to fint a method that will 
allow me to do so.


If i try to calculate it using the assigned font, I have the problem 
that TEdit.Font.GetTextWidth always returns the default size (16), since 
the Font doesn't have a canvas assigned to it.


The TEdit itself does not really have any methods for calculation the 
caret position in pixels either.


All suggestions are welcome. :)


Kind regards,
Torsten Bonde Christiansen.

Re: [Lazarus] LCL High-DPI request for help adding images

[Torsten Bonde Christiansen via Lazarus]

How do i use icon scaling for user project?

Regards
Torsten.

On 2017-02-22 00:33, Ondrej Pokorny via Lazarus wrote:

Update: I worked further today (unfortunately...)

I also added icon scaling support to the IDE. The IDE now can load 
150% and 200% versions of the icons. If a High-DPI icon is missing, 
the normal icon is upscaled (with the worst algorithm, but that's what 
is available in the IDE).


Request: search for volunteers who would add at least the most 
important IDE icons (open, save, desktops - basically what is visible 
in the coolbars). Please see images/README.txt for more info.


Note: the High-DPI icons are used only from 144DPI (150%) upwards. 
120DPI (125%) uses the original icons (which is default on Windows, 
AFAIK).


Thanks

[Lazarus] "protected" as class property incorrectly highlighted

[Torsten Bonde Christiansen via Lazarus]

Hi List.

I ran into this situation by random - but examplified here (using 
Lazarus IDE):





As "protected" is not a reserved word 
(http://www.freepascal.org/docs-html/current/ref/refse3.html#x11-11.3) 
in any modes I think this is a bug in the highlighter.


Should I report it to the bugtracker?

So, what do you think about distributing it on Lazarus components 
directory and it cames installed by default in the IDE?


Anyway, I'm going to send some patches to improve this component ...



If it all possible, can the part that generates the RichTextFormat be 
moved from the component into a seperate unit. This will make it 
possible to include RTF generators into eg. console programs.
