[lazarus] CodeTools help
Hi, Is there any wiki site or other documentation for CodeTools? I am trying to convert some of the GExpert tools from Delphi to Lazarus. I am looking at the Code Explorer in Lazarus as an example which is helping... Question 1: I need to retrieve a list of procedures and functions from the current editor file. Code Explorer is based an a Treeview. The one I am busy with is not, it will just populate a TListView with all procedures and functions. Does CodeTools only return a treeview structure of the current editor file, or is there another way of doing this? Question 2: Where does Code Explorer link into CodeTools to retrieve info from the current editor file? From what I can see, it looks like the code in the Refresh method: // get the codetool with the updated codetree ACodeTool:=nil; if Assigned(OnGetCodeTree) then OnGetCodeTree(Self,ACodeTool); Is my assumption correct?

Re: [lazarus] After upgrading to gtk2
It is OK now. Captions is not a problem because I read interface captions while running, stored in a unicode text file. Components are now displayed in design time but, it is not possible to display buttons in TToolBar. Frame of ToolBar is displayed but no its contents.

Re: [lazarus] transparent forms
How does it work? Does it scan the form and build a region or so? Sounds like a horrible hack to me TBH. How do you use it ? Well there are a few ways one could achieve this, the worst hack being to have the code scan the form and copy whatever is behind it on screen onto the section you selected, that is a horrible way. Now on MacOSX and Linux (at least with newer versions of X) it should be possible to do TRUE translucency. On linux by tapping into the Xcomposite and Xrender extensions, not sure how you get to these features on Mac. On windows I don't know but different implementations for supported platforms is quite okay if the interface to the component is the same. I do think it would be a nice-to-have but right now I doubt there is a clean multiplatform approach so a per-platform implementation would be needed and it's not lazarus style to add components that work only in one place. I do reckon that a lazarus component which can tap into the features of xcomposite manager would be really neat though, not sure what it would take to create one, especially if you don't want to use a tprocess, I suspect our X-header conversions don't include the functions it uses so it may require converting some code from the c project by X.org. Of course it won't work on all versions of X only those that have the right support compiled in (which is alpha code right now) but it would mean that where available lazarus apps can be xgl enabled, users could have a slider right in the app for adjusting transparency... neat nay (of course I think this will be whole-form only though it could surely be mapped into a component as well to affect only that which is in the bounds of the component - personally I would like both - the component could have a slider letting the user adjust the transparency of the region it encapsulates (and otherwize look and work like say a tgroupbox) and another component which would be simpler and probably non-visual but would adjust full form transparency to whatever value you pass it in properties) Wow that was a lot of bracing :p Anyway, just some thoughts from me on the topic.

I think I already sent you an article which partly explains what you

implement one of the GExpert buttons (jump to interface uses,
implementation uses etc) and how to place it on a toolbar in the IDE

Hello,
First: I'm using FPC SVN 2.0.3 from 2006-02-24 TSqlite3Dataset version.

Platform: Windows XP Home,Lazarus SVN rev.8817
I already sent a patch to fpc maillist. I'm waiting for the commit.
Why is impossible to use Edit,Post,ApplyUpdates,Refresh functions
for TSqlite3Dataset in SQLMode ? I have defined PrimaryKey which is
INTEGER PRIMARY KEY but is it skipped (for example ApplyUpdates has
check for :
if (FPrimaryKeyNo -1) and not FSqlMode then (...)
)
So that code does not update database table at all (in SQLMode):
DB.Edit;
DB.FieldByName('Test').AsString := 'Test';
DB.Post;
DB.ApplyUpdates;
DB.Refresh;
For me it's strange because update/delete SQL should work flawless
with SQlMode when PrimaryKey is set (even if table has not define
primary key there is ROWID variable to obtain record ID which may be
used for update/delete statement)
SqlMode is intended only when you want to use queries that retrieves
data from more than one table or use field aliases. It prevines data
corruption when using ApplyUpdates. When using queries that retrieve
data from only one table, without using aliases, even complex ones,
ApplyUpdates will work and SqlMode should be set to false. Notice that
only ApplyUpdates is affected by SqlMode. All other functions you
cited does not.
I will remove the SqlMode property since it will cause a lot of
confusion like this and in fact it does not prevent calling ApplyUpdates
in the cited situation. I'll make clear in the documentation (when it's
done) that ApplyUpdates will not work in queries with fields of more
then one table. I already have planned to extend ApplyUpdates to work
with such queries but no time yet.

Maybe it's easier to revert your component to SQLDb.
SQLDB has a working ApplyUpdates, even for queries
with fields of more than one table.
You would then also have parameter support and so on.

The short version is because the LCL is NOT the interface it is using, lazarus compiling to GTK1 does not mean you are using GTK1.

The big thing is that you have the Object Pascal way of telling components how to behave on one side, and whatever method is typical in the widget set on the other side - the LCL basically translates the one to the other - so the translation to GTK1 for ownerdraw isn't the same as for GTK2 because GTK2 doesn't use the same calls as GTK1 did. With me so far ? Right now GTK2 is actually more complete than QT and Carbon mostly because a lot of the calls are similar to the highly mature GTK1 which allowed for a faster conversion, but it is not I think production ready.

Now, you seem interested in helping to shorten that time, the place to start is the layout and readme text files in the LCL subdirectory of your lazarus source tree, get an idea of how the LCL interfaces are laid out, then go into the subdirectory that implements your target widget set and start hacking the code, when you are done, recompile lazarus and try it out, repeat.

At first I didn't know this, and I wondered why I didn't see the debug messages on the screen. Yes, the background is frosen, but you don't need to use a full screen form. If your form isn't fullscreen, the parts inside your window which are transparent will still be frosen, but the rest of the screen won't. There is no really good or easy way to go around this unless you use the more powerfull platform specific methods, which are: DirectX on windows X Composite extension on very new X.Org's on Linux Aqua on Mac OS X -- Felipe Monteiro de Carvalho _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Under Linux it looks similar, but the reference to 950 would seem to be a problem with comctrls.pp as well as win32wscustomlistview.inc. What am I doing wrong ?
