Re: [Lazarus] Tagging 0.9.30
In NASA's style, the answer is GO. Roger. We agree wholeheartedly. And while you're starting on that, I'll just read these notes on P22. Call P22 possible program alarm 526, range greater than 400 nautical miles, and then use the P22 as described on PGNS-20. Take option 1 in Noun 06, and use the no-update mode. The rendezvous radar will lock on at about 25 degrees elevation above the horizon. If 503 alarm occurs, designate Fail. Key a Proceed and allow the rendezvous radar to search for the CSM. And place the range altitude monitor switch in altitude/altitude rate to prevent the tape meter from driving into the stops. And press on. Roger. I think I have that. Columbia, Columbia, Houston. Over. Houston, Columbia. Roger, Columbia. We'd like a Cryo(genics tanks) stir - all four tanks - and the standard 1 minute. Over.

[Lazarus] CharMapDialog and more...
Hello I've encountered a strange behaviour after installing today's Lazarus snapshot on my Win2k in VirtualBox. When I select Edit - Insert from Character Map after starting the IDE, nothing happens. After a while, I found out that it's showing up only after I've once clicked in the editor window. If this is intended, the Menu Item should be disabled in this case. But before that, I've tried to run the IDE unter GDB to see if there is some error message. I have no idea if this is anyhow related, but the IDE didn't start up completely.

[Lazarus] GTK2 version questions
Hello
I have a question regarding this bug rep.
http://bugs.freepascal.org/view.php?id=17010
Is there any backward-compatibility limit for Lazarus regarding GTK2
versions?
The functions imported there are from 2.8. Afaics, it was released 13
August 2005.
This should be OK to use, right?
If I'd make a patch for this function, do we always wait for FPC to
include a certain GTK2 API or is there a unit somewhere for our own imports?
If not, I guess I'd have to make a patch for
/trunk/packages/gtk2/src/gtk+/gtk/gtktreeview.inc like
{$IFDEF HasGTK2_8}
function gtk_tree_view_get_visible_range(tree_view: PGtkTreeView; out
start_path, endpath: PGtkTreePath): gboolean; cdecl; external gtklib;
function gtk_icon_view_get_visible_range(tree_view: PGtkTreeView; out
start_path, endpath: PGtkTreePath): gboolean; cdecl; external gtklib;
{$ENDIF}
Correct?
Thank you
Theo

Thanks for your answer Matthias String properties always have as default value the empty string. But you can define a stored procedure. See the TControl.Caption property. I don't get what you mean. There I read: property Caption: TCaption read GetText write SetText stored IsCaptionStored; where afaics IsCaptionStored determines whether or not to store the Caption value. But I simply want it always stored, even when empty. Since it doesn't seem to work with empty string, I use a workaround which does the job for me: procedure TThumbControl.SetDirectory(const AValue: UTF8String); begin if AValue='' then fDirectory:='none' else fDirectory := AValue; if (fDirectory 'none') and (fDirectory '') then if DirectoryExistsUTF8(AValue) then begin Thank you Best regards Theo -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Question about SVN version stability
I have a question regarding the current status of trunk. I have a self written component which is going into eternal loop in the area BoundsRect. It worked for several versions before current 0.9.29. It's very well possible that it's a bug in my component. I'm just asking if it's worth investigating the problem on my side, or if I should just wait for a stable LCL version in the area of AutoSize probably. It's a component with scrollbars the way synedit is using it (CreateParams). It is resizing Scrollbars also with the changing content dimensions. So tracking down this issue is not exactly easy.

[Lazarus] Hiding Comments
I know this is probably hard to implement but I sometimes would really like to have it. ;-) I have some heavily commented code, be it for the following reasons. - Comments explaining what the following code is doing, sometimes line by line. - Comments which keep some thoughts of previous implementations in code (not for shipping) but which might be helpful and be it only for not going that route again. - Some todo stuff (I know about the todo feature). I think it would be helpful to hide all comments at times, because while helpful, they make reading the actually working code a lot harder. Does anybody know if this is implemented somewhere in other IDEs? Does anybody else think this would be a good feature? Does anybody have a suggestion how to implement this? Don't beat me, it's just a question and I have no answer. ;-) Thanks -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

it is a lovely sunny 24 degrees here in Tasmania, Australia, very nice :) Humm, it's -10 (Celsius) here in central Switzerland. Swiss Intl. Air Lines offers three flights to Hobart tomorrow.

Re: [Lazarus] Reconstructing Lazarus Website 4: the dev tool

Re: [Lazarus] Reconstructing Lazarus Website 2: the content
@Aleksa I almost completely agree. There should probably be a section with these information on the first page. The first page should primarily be for those who come for the first time - to attract them, and show them what Lazarus really is. Exactly. This is important and could be done in reasonable time. This is much more important than changing website technology imho. Only thing I do not agree: I think we should not compare Lazarus with Delphi and other tools. It's a little cheap / bad taste.

[Lazarus] LCLGTK2 no visual updates

Re: [Lazarus] cross platform [Re: Lazarus Goal]
Unfortunately this brings up the idea of aesthetic, Consider the Preferences dialog in Mac Leopard's Mail client: http://web.fastermac.net/~MacPgmr/Lazarus/Screenshots/mail_prefs.jpg http://web.fastermac.net/%7EMacPgmr/Lazarus/Screenshots/mail_prefs.jpg I don't think this dialog has a lot do to with aesthetic. It looks cheap to me. The Icons look like randomly collected from the net. No common height or color style, strange vertical alignment (see RSS). Vertical alignment is almost inexistent anyway. Look at the checkboxes vs. the comboboxes. comboboxes blue green red don't even have the same distance Nah, really... ;-) -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Case error with cirilyc
You might try utf8scanner http://wiki.lazarus.freepascal.org/Theodp
This should do what you need:
procedure TForm1.Button1Click(Sender: TObject);
var s :TUTF8Scanner;
begin
s := TUTF8Scanner.Create(Memo1.text);
s.FindChars :='абвгдabvgd';
//Memo1.text:=s.GenerateCaseStatement(); //Writes the case block for you
repeat
case s.FindIndex(s.Next) of
{а} 0: s.Replace('a');
{б} 1: s.Replace('b');
{в} 2: s.Replace('v');
{г} 3: s.Replace('g');
{д} 4: s.Replace('d');
{a} 5: s.Replace('a');
{b} 6: s.Replace('b');
{v} 7: s.Replace('v');
{g} 8: s.Replace('g');
{d} 9: s.Replace('d');
end;
until s.Done;
Memo2.Text := s.UTF8String;
s.free;
end;

Re: [Lazarus] Case error with cirilyc
You should not replace multiple characters with this method like
s.Replace('ввв');
It works for me, if I write
s.Replace('в');
It outputs: kввgd then
Make sure your file encoding is UTF-8 (standard)
If you really need to replace with ввв then write the output in a second
string like you did before.

Re: [Lazarus] Groupboxes in the IDE
Well, it's doing that already by using the Label 2xBevel isn't it?? Yes, I counted these as //groupbox-alikes too in my prev. message. I don't mind if you use custom components for the IDE if there is a good reason to do so. But you should be aware of the fact that they do not follow themes with the current solution. As long as both (TGroupBox, custom groupbox) are used together, it may look inconsistent mainly because of different caption-font. // -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] Groupboxes in the IDE
Is there a reason, why the Lazarus IDE is using groupboxes with normal font as well as a combination of bevels and label with bold font for groupbox functionality? For ex. IDE Options - Environment vs. IDE Options - Editor. It think this doesn't look consistent. I vote for using TGroupBox with Font.Style:=[]; all over the place.

Re: [Lazarus] Lazarus has unique font sizes
I think it should be like this in Delphi: Since size and height change the same value with a slightly different meaning (PPI) whichever value was set, the other one is rounded and gets a negative value. If you set size you should get a negative height and vice versa. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
