Re: [lazarus] some questions
You are not missing a unit, you have a conflict between the definition of an event in the form file and the actual. event handler in the unit file. I've run across this on a couple of occasions and the only what I have found to resolve the issue was to open the form file and determine which assigned event in the form file does not have a corresponding handler in the unit file.

I have a few questions, first I registered to the forums but never received an e-mail back with password so I cannot log in. I have two questions that pertain to the Linux version of Lazarus 1) I use a form and then I click in the OnCreate Event Handler in the object inspector and it returns an error "Unable to find method. Plz fix the error shown in the message window.". I look at the message window and the error is "Error:unit not found:Forms". I take the same code into windows and do not have this problem. Any ideas. 2) I would like to use MySQL with Lazarus. I have no idea where to start. I placed a MySQL50conn module.

In my opinion having a OnDropFiles or so would be nice to have. Note that XDND (X Drag and Drop) and XDS (X Drag Save) payloads are somewhat sophisticated, so I'm not sure if OnDropFiles can do much stuff on behalf of the programmer. That is, even with OnDropFiles provided, it still will be a bit of work for the actual application programmer to get some useful data out of the drop :) Do we want to handle the "drag" part of "drag&drop" too ? :) Of course.

Maybe these hints can help: The completion box supports at the moment: Word completion, Template completion and Identifer completion. Word completion and Template completion collects the whole list and put them into the ItemList. Identifier completion is far more dynamic. There can be easily thousands of items with long parameter lists. So adding them to the list would be far too slow. The codetools do nearly everything on the fly. They don't for example create strings to put into the list. They only gather code positions, and when the user scrolls, the codetools read the information as needed. About hints for identifiers: I think, 'eclipse' has a nice idea: Right to completion box it puts a second box of the same size and shows the help for each item. This has the advantage, that you don't need the mouse and no new shortcuts. This information is also available in lazarus. We have the fpdoc xml files. What we need: 1. a hint window to right of the completion box. 2. the search for the fpdoc/xml path 3. the parsing of the fpdoc xml item and showing as formatted text If someone implements 1 and 3, I will do 2.

[lazarus] Some questions on Identifier Completion of TSourceNotebook
Have been looking at UnitEditor.pp and SynCompletion.pas. I'm trying to implement item hints on SynBaseCompletionForm of ACompletion of TSourceNotebook. That is, when mouse is over an item of the identifier completion list, a hint pops up to display and describe the item. (Useful when looking at items that are longer than the completion form can show it, especially overloaded functions) Is it implemented halfway or not at all? Is the 'ItemList' property of ACompletion of TSourceNotebook used for this purpose, as I see it is filled with 'Dummy' strings, which looks like initializing ItemList? If its not the above, i'll have to add a FHintList to TSourceNotebook. Asking first so as not to cause overlapping codes.

Note that depending on the presence of a window frame is bad. The frame
(and thus the frame size / orientation) can change while the application
is running (every time the user switches to another window theme). It
can also change depending on the window title, or window flags, or when
you change the display resolution, or start another window manager (i.e.
terminate the current one) while the application is running. Maybe the
window itself is animating (opening/closing animation) and thus the
window frame (and thus the size) changes rapidly. Maybe the window is
minimized/hidden and has no frame yet. Maybe it is docked within windows
of other applications (i.e. tabs) -> they have one common frame. Maybe
it is running on a small display and hence nothing has window frames at
all. Maybe the window frame (and frame size) changes depending on if the
window is maximized or not.
gtk does not provide a way to determine the current frame extents.
That said, it is possible to find out the current frame extents, via
xlib, if the window manager cooperates.

http://standards.freedesktop.org/wm-spec/wm-spec-1.4.html#id2511948

you can get it with the normal Xlib function too, which is

There are xlib bindings for fpc, so it shouldn't be hard to get it
working.
Hope that helps.

Re: [lazarus] Some questions about TForm.Height
Thank you for your help. :-) Can you explain why you need the complete height ? As I told you - I need to work with 3 windows. 1st is top window (like Lazarus main window). 2nd and 3rd must be placed under that window. So, I do: F2ndWindow.Left:=1; F2ndWindow.Top:=F1stWindow.Top+F1stWindow.Height; F3rdWindow.Left:=F2ndWindow.Left+F2ndWindow.Wight; F3Window.Top :=F1stWindow.Top+F1stWindow.Height; Im Delphi all is correctly calculated. In Lazarus both F3rdWindow.Left and F3rdWindow.Top are calculated wrong. So. How can I obtain titlebar height (both in WIndows and in Linux) to get a real height of my window? Best regards. Alexey.

The height of the Window title bar can be obtained in windows through the system metrics, just as the width of the scrollbars etc. In Delphi - Height is the height of the window + the height of the title bar - Clientheight is the available height of the window. This becomes smaller for MDI Windows, as e.g. the menu height is substracted from the height. There are probably some other subtleties which I'm unaware of, but the above should be more or less correct. Since Lazarus cannot offer a method to get the title bar height on all platforms (notably Linux/Unix), the most sensible thing to do is to make Height=ClientHeight...

Re: [lazarus] Some questions about TForm.Height
Problem description: I have 3 windows(Forms). 1st form is on the top of the screen - like Lazarus main window. I want to show two other windows below the main window, and closely to each other. So I wrote: SecondForm.Left :=1; SecondForm.Top :=MainForm.Top + MainForm.Height; ThirdForm.Top :=MainForm.Top + MainForm.Height; ThirdForm.Left :=SecondForm.Left + SecondForm.Width; This code works well in Delphi. But in Lazarus I see that SecondForm and ThirdForm IS NOT placed below the MainForm - they are ON IT. So the .Top of 3rd and 2nd windows are not calculated correctly. It is smaller than expected and the difference is looking like a height of main window TitleBar. I try to find some information about this in Wiki and also in other Lazarus documentation, examples, but had found nothing. Thank you for your help. Regards, Alexey.
