[lazarus] Raize programmer font (and now for Linux too)
Hi, In all the years I programmed with Delphi, I used a programmer font called Raize. It is simply brilliant. It makes a clear distinction between 0, O, o, i, I, l, etc.. and Monospace obviously. Above all, it looks good (much better than Courier). For Windows users, you can download it for Free from the following location. http://www.raize.com/DevTools/Tools/RzFont.asp Unfortunately the FON file was in a strange non-standard format (some compiled windows DLL) so it wasn't possible to convert to a Linux PCF font format. I did email the company that created the font. They said I can convert it if I want, they don't mind. Unfortunately they weren't going to help me. No surprise there! :) In the end, I decided to do it the hard way and manually design the Raize font for Linux using FontForge. I have recreated the 11 point font (about 13 pixels in size on a 96dpi screen setting). I created the Normal and Bold characters. I don't use Italics - instead I use syntax highlighting which works much better. Attached is the Raize font for Linux. I also included a screenshot of sample code to show how the font looks. Later, I'll recreate the 12 and 14 point font for higher resolution displays. For those that don't know (or can't remember) how to install fonts under Linux: 1) Unpack the archive to /usr/local/share/fonts/bitmap 2) If other fonts already exist in the above path, then run the following: sudo mkfontdir /usr/local/share/fonts/bitmap 3) Add the following FontPath line to the Files section if it doesn't exist in your /etc/X11/xorg.conf file: FontPath /usr/local/share/fonts/bitmap 4) Restart X To view the font you can use Lazarus of xfontsel: Normal: -fontforge-raize-normal-*-*-*-*-*-*-*-*-*-*-* Bold: -fontforge-raize-bold-*-*-*-*-*-*-*-*-*-*-* Settings for use in Lazarus: Editor font: -fontforge-raize-normal-r-normal-*-*-*-*-*-*-*-iso8859-1 Editor font height: 13 (for some reason it defaults to 10) Enjoy!

[lazarus] Form designer code inside .pas unit
Hi, What are the pros and cons for letting the form designer add code inside the .pas unit instead of a separate .lfm file? For example: Lazarus and Delphi uses external files (.lfm and .dfm) to save information about forms designed using the form designer. Visual Studio and CodeGear's C# IDE's use the source code unit directly instead of a external unit. They embed the form/component creation code inside a private method called from the constructor. The code in that private method is also wrapped in C# Region so that it is hidden by default with code folding.

The GUI design was made with Glade and translated to FPC. Now I'm trying to run a minimal Lazarus GTK2 application (a form with a button) on the same board, with the problem I reported. So that arm-board is the machine that runs my X-server. I'm sorry, I don't know exactly what the problem is. I think it's quite strange that some programs will contact the X-server, and others not.

I'm not sure I understand that statement. :) The form definition is stored in a resource as text. In theory you can replace the resource with another resource. The translation engine of Delphi relies on this, for instance... Suppose I have a form definition: MyForm Object TMyForm Caption = 'A nice form' Width = 200 Height = 100 end Then it can be replaced in the running binary by e.g. a translated version MyForm Object TMyForm Caption = 'Een leuk venster' Width = 220 Height = 110 end With adapted width and height (a dutch text is usually longer). The alternative version can be loaded from a resource dll, or from file. XML comes to mind: the original author of fpGUI imagined that the original form is stored as XML. It would then be easy to create a second XML 'overload' part which can be used to change the visual appearance of the form. This second XML file could simply be loaded from a file on disk. Using the constructor method, all this is not possible (well, I suppose you could find a way, but it would be less elegant). Since the form definition is now just text, it can be simply replaced with another text. If the form definition was XML, this would actually be very easy. Now it is slightly more complicated.

[lazarus] Making Configure Build Lazarus more user friendly
The configure build lazarus IDE provides a lot of options which the majority of us don't use, but we're however forced to check/uncheck. Therefore I've added a small Group Box, named Quick Configure Options with thre buttons: All, LCL, and Custom. The first two cover (in my opinion) the needs of the vast majority of users, while the third one can be handy. The All Button checks all the Build (or Clean+Build, if Clean All is checked), the LCL button unchecks everything, except LCL (which is set to Build or Clean+Build as above), while Custom unchecks everything. If the idea seems good, the attached patch can be applied, or someone can do it better. If not, I'll just keep it for me, because I find it handy.

No, via code is actually faster. It saves the RTTI lookup etc.
Can you explain the 'replace at runtime' part a bit more. I'm not sure
I understand that statement. :)
The form definition is stored in a resource as text. In theory you
can replace the resource with another resource. The translation engine
of Delphi relies on this, for instance...
Suppose I have a form definition:
MyForm Object TMyForm
Caption = 'A nice form'
Width = 200
Height = 100
end
Then it can be replaced in the running binary by e.g. a translated version
MyForm Object TMyForm
Caption = 'Een leuk venster'
Width = 220
Height = 110
end
With adapted width and height (a dutch text is usually longer).
This issue comes (in Delphi) from the absense of layout manager. In fpGUI or
GTK, you can simply translate the necessary strings, and the form will realign
itself properly. IIRC, gtk/glade has single XML file in which the strings that
need translation are marked as such. The translation is done with gettext,
using .mo files.
Yes, but this is a crude mechanism...
The alternative version can be loaded from a resource dll, or from
file. XML comes to mind: the original author of fpGUI imagined that the
original form is stored as XML. It would then be easy to create a second
XML 'overload' part which can be used to change the visual appearance of the
form. This second XML file could simply be loaded from a file on disk.
A thing that I must mention is at runtime and at initialization are not
the same. Typical program state is not limited to form resources, it includes
non-published properties, manually created objects, etc. At initialization
time this state is generally known, but later on it is not. All attempts to
reload resources at the middle of execution that I have seen were a mix of
hacks with black magic, and work only in particular cases.
Could be, I don't have bad experiences :-)
Using the constructor method, all this is not possible (well, I suppose you
could find a way, but it would be less elegant). Since the form definition
is now just text, it can be simply replaced with another text. If the form
definition was XML, this would actually be very easy. Now it is slightly
more complicated.
Not too much complicated, I believe:
1) Declare translatable properties as a separate type
( like 'type TTranslateString = type string;' )
2) While generating code, wrap strings that are being assigned to such
properties into gettext call
( e.g. Label1.Caption := _('Caption'); )
This is so, but you are limiting yourself to the translation.
The overlaying mechanism could be used to implement rudimentary theming,
for instance. To reuse my example:
Original:
MyForm Object TMyForm
Caption = 'A nice form'
Width = 200
Height = 100
end
Overlay:
MyForm Object TMyForm
Caption = 'Een leuk venster'
Width = 220
Height = 110
Color = clYellow
Icon = some icon resource
end
I'm not saying that this is the way to go; All I was saying is that this was
one of the ideas behind using resources instead of using code; it requires
no extra streaming code: it's all already there. What's more, the additional
resources can be inserted later at any time; With code this is harder to do.
You may need to re-generate all existing code, and make sure you don't
destroy any modifications the user made in the code. With resources, it's 1
extra call.

Crude as it may seem, it is a lesser of two evils. Having an application
with 10 forms, localized into 10 languages means that you have 100 files
to maintain. If any one of these 100 gets outdated (in terms of
adding/deleting objects; merely changing properties is not so
dangerous), application will most probably not run at all.
Otoh, the ability to update resources independently of code is probably
valuable for closed-source projects.

Theming may also be implemented by using string substitution mechanism.
All you have to do is declare styles that are referenced by name (and
this is also key point of fpGUI!).

RE: [lazarus] Problem with lazreport
Be cool, its a cheetah, dont worry! I have the 32 bits version of lazarus running on Windows vista 64 bits. Perhaps it is a OS incompatibility issue, because on a virtual machine with xp 32 bits, the same lazarus works properly. Regards Germán C.

[lazarus] IDE dialog position question and the IDE
I run dual monitors, with a desktop size of 2560x1024 Nearly every dialog used by Lazarus is set poDesktopCenter, which splits right down the middle of my two monitors, leaving half the dialog on each monitor. Is there anything that can be done to change this? Almost every piece of Linux software I run that pops up a centered dialog centers it to one monitor or the other automatically... Windows is another story, I can't get a darn thing to not bridge the center of the screen in Windows lol. I've tried every window position known to man with a test form... poDesktopCenter and poScreenCenter both do the same thing for me in both GTK1 and GTK2. They place the form centered vertically and pushed up against the edge of the screen at the split, but it doesn't split across both screens. So, for a window, I am unable to reproduce what's happening with the IDE. Dialogs I open such as showmessage() still bridge the center. -Tony

Zitat von Graeme Geldenhuys [EMAIL PROTECTED]:
Hi,
Does Lazarus support some sort of code folding 'region' keyword like
the Visual Studio IDE does? I know Lazarus automatically handle
begin..end etc. But can the user add there own code folding regions
around their code.
Here is an example of regions used in the Visual Studio IDE for C# code
#Region Windows Form Designer generated code
...
System.Diagnostics.DebuggerStepThrough() _
Private Sub InitializeComponent()
Me.components = New System.ComponentModel.Container
...
Me.ImageList1 = _
New System.Windows.Forms.ImageList(Me.components)
...
#End Region
Just add that to the highlighter TSynPasSyn and it will support it.

Hello guys!
In CodeGear that is achieved with these tags:
{$REGION 'Description about the fold'}
Code
..
..
{$ENDREGION}
For IDE related hits, I would prefer
{%REGION 'Description about the fold'}
Code
..
..
{%ENDREGION}
(since it is no compiler directive)

Tried this, and got another result.
./project1 --display=viper:0
gives :

then a form appears (with a red circle with a white bar in it) :
Invalid Filer Signature
Press OK to ingore and risk data corruption.
Press Cancel to kill the program
[ OK ] [ Cancel ]
And the form seems to respond to a click on one of the buttons, it
terminates the application.
This is some progress, thanks. Other suggestions ?
at leas this is no: Gtk-WARNING **: cannot open display:
so you now have your display and ran into a complete different problem.
Exception=Invalid Filer Signature:
maybe some endian issue or a corrupt file or a bad compiled string
constant (the form layout is stored internally in a string)
Maybe, as a test, you can write the contents of the result of
LazarusResources.Find('TForm'):TLResource directly after the line {$I
unit1.lrs} in the initialization section of your form.
(and compare this to the contents of unit1.lrs)

It should be mostly simple things, like ifdefing parts which require X11. afair I've ifdeffed all parts. So it should compile on windows. However, I didn't write replacement code for the X parts, so you should do it without keyboard support.

[lazarus] Linux/Printing Question
Hi all, This is quite a bit OT since the only thing related to Lazarus is that I will use to write the software. One of my company's main products does a lot of prep notifications to various printers on the network. For a single order (sale), prep instructions can be sent to up to 6 different printers. One of the things that has always been a problem with doing this kind of critical printing in windows has been the lack of status or way of querying printers (many are on print servers). I remember there was a way to send a fake print job and monitor using the Win32 API, but I had difficulty getting reliable printer status and it doesn't seem to work very well. Is this kind of printer monitoring possible in Linux? We are thinking about putting together a kind of Linux Appliance to do this and move the printing portion away from Windows, assuming printer status is obtainable on Linux like outlined above. Thanks for input. -- Warm Regards, Lee _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
