Re: [Lazarus] What are widgets in lazarus?
Graeme Geldenhuys schrieb: As mentioned above, *every* dragmanager must have handles for all involved components. An OS-wide dragmanager can only use OS-wide handles, e.g. those of the OS-wide window manager. Lets take Windows OLE drag-n-drop protocol as an example. It needs the window handle of the component (eg: TEdit) that can accept a drop. So what? If somebody *wants* to allow OLE drag-drop for a component, he must choose an appropriate one (here one with a HWND, or some other OLE/COM object). If you want such dragging for a single pixel, you must wrap that pixel into an container that supports dragging. Drag-drop does not come at zero cost. Irrespective if it is a drag-from-component-to-component-inside-same-app or a drag and drop from one app to another. In Qt 4.4 and later, such an Edit component doesn't have a windows handle any more, so OLE can't talk to that Edit component. The only OS window handle is the top-level form. Trolltech had to implement some serious black magic in Qt to still work with OLE DND - yet no difference to the end-user. This is what I'm so impressed with, and have no real clue how they accomplished that (yet). I cannot see any black magic here, even if it may sound like that to marketing people. When the OLE dragmanager needs a HWND, for sending messages to a source or target, any such HWND is sufficient. The receiver of the message can determine a more specific source or target at will, i.e. allow for an drop inside a window only, when the coordinates match a specific control inside that window. The Lazarus dragmanager does this already. If nothing helps, the application can create a temporary invisible window, or any other applicable OLE object, on top of the target control. This object then can be moved to every possible target control, that resides at the current mouse position. But this is not a necessary requirement at all, when the screen position of the target area is explicitly stored in the OLE object. There exist more components, like timers, that have no visual representation at all, but have a HWND for communication purposes. XDND protocol works very different to Windows OLE DND, but still X11 window handles are required for the component which is the source or target of a drag-n-drop action, including the top-level window handle so as to communicate with the other app or component. So that's not really different from any other (Windows...) dd. And when I say drag-n-drop, I mean full DND support. In app drag-and-drop (component to component in same app) and application to application. XDND even allows computer-to-computer DND. What does dropping mean other than a notification (message...) to the target (handle), that a source (handle) has been dropped onto it? The DND support Delphi has in the VCL is a joke, and hardly what I would call real drag-n-drop. It's just one component inside the same app sending a message (or executing an event) on another component in that same app. Sorry, that's nonsense :-( You should understand VCL/LCL dragging first, before you make wrong assumptions about different operation and requirements of other drag managers. It were no problem to extend the LCL dragmanager to inter-process dragging. But since there must exist conventions, how a target window of *any* application will signal acceptance of an possible drop, and will handle the drop, and will handle the dropped source (residing in another process), it's a much better idea to use the existing OLE dd conventions for *that* purpose. You also should understand that Delphi dd is not limited to source controls (Lazarus missed that aspect a bit), so that the TDragObject is equivalent to an OLEDragObject, only with an different set of methods and properties. Any app-to-app DND, and you are on your own (outside the scope of the VCL), and you have to resort to Win API calls or implement your own full OLE DND implementation. Right, because a process needs some OS support, for communication with other processes. That's nothing new, isn't it? And when OLE dd requires HWNDs, that's a justficiation for another LCL dd, that comes without such heavy requirements.

[Lazarus] Lazarus editor font height very small...
I installed Lazarus on my WinXP virtual machine from the fixes_30 branch a couple of weeks ago, but have not used it yet (Xmas and all). Now I just started and found that I needed to set the editor up for my usual look. One thing that is very strange is the font size, when I set it to 10, like I usually do in Delphi, the text is nearly invisibly small! Is Lazarus using a different size unit than Delphi is? I usually set the font to 8 or 10 to get a comfortable view of the code but that does not work at all in Lazarus, here I need to set it to 16 or even 18.

Re: [Lazarus] event code tool compilation error
Yes, I updated my FPC 2.5.1 today. I downloaded the file fpcbuild.zip
from http://www.freepascal.org/develop.var on Download Daily Source
Snapshot of Development Tree (trunk) section
I'm looking the file typinfo.pp of my fresh fpc version, searching
the TMethodKind type and it don't have the mkOperatorOverload.
I looked the same file via FPC svn and it have this. Maybe I
downloaded the wrong file. I'll try download the fpcbuild.zip again
and see what's happens.
While I write this message, I checked the date of the downloaded file
on ftp, and it dated of 2010-nov-16, and if 'operator overload' came
some weeks ago, this is the problem...
After this, I'll update my fpc via svn...

but I can't see anything wrong...
I searched the wiki and the bugtracker, but I found anything. On
google, on some pages is wrote that to solve this, I have to update my
FPC (my previous version of FPC is 2.5.1 of november of 2010). I
updated it but the error persists.
Some Idea?
You need a recent 2.5.1 or a released 2.4.2 or a recent 2.4.3.
The 'operator overload' came some weeks ago to 2.5.1.

That's simply because the UI is defined as actual source code (just like Qt Creator, any Java form designer, MS Visual Studio etc), and gives the developer a guaranteed creation order of components. I don't see that as a bad thing, just different to Lazarus and Delphi's UI designers, which use external object form file to load the UI. You shouldn't mix IDE and Runtime here. Qt as well as some Java UI Designers (at least Matisse) use separate form files. Qt generates the C++ code out of those during the build process, Netbeans afaik updates the Java source while editing. But the designers in both cases rely on the external files to manage the forms. I guess it wouldn't be too hard to write a similar preprocessor for Lazarus too, that converts the lfm into actual code, but there doesn't seem to be enough benefit.

Re: [Lazarus] What are widgets in lazarus?
On Mon, 10 Jan 2011 14:20:47 +0100 (CET), wrote: This is not correct. People do strive to 100% the same everywhere. But the 100% the same working on all platforms is hard to reach, and takes time, it is an ambitious target. Rome also wasn't built on a day. I don't think that 100% the same everywhere is possible or even desirable. Take a look at Java SWT. It certainly has a much much bigger amount of contributors than Lazarus, being THE backend behind Eclipse. Yet it doesn't have half of the features the LCL has (hell, it's really a pain doing a serious GUI with it). But even though they limit the available widgets, it is STILL not completely identical across all the three supported platforms. Another point being: is it really THAT important to have it 100% the same? A UI that is great on Windows will probably suck in MacOS X. Why? Because they have other design guidelines. Sure, it's easier to ship out one and the same for all, but I think serious UIs are better designed for a specific market, and not run-of-the-mill. That of course also depends on the use case. So I think it's fine that there is a choice: specialized GUI (frameworks) on the one side, fpGUI on the other side, and the LCL in between. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

I think you still don't understand what the LCL is. Imagine the LCL as a frontend. It has several backends it can choose from - but only one at a time. One of them is GTK, another is GTK2, yet another Win32 and in the future maybe fpGUI. That has nothing to do with mixing anything. fpGUI would operate on a whole other level than the LCL in that case. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
