Re: [Lazarus] The mouse doesn't appears in Windows Mobile 6.5
2011/7/30 Arí Ricardo Ody ar...@gmx.com: It's a hello world like program. It runs ok in windows. When a copy it to my Windows Mobile 6.5 device and run, the screen appears just like in the windows at the desktop, but the mouse is not showed. I can execute the functions via shortcut combinations programmed in the buttons. How can I show and use the mouse, please? Which device are you using? It has no touch screen? You attached a external mouse to it? Does the mouse show on other applications? LCL-Wince does not do anything special to show or hide a mouse. -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

2011/7/30 Arí Ricardo Ody ar...@gmx.com: Copy “browseslqiteprj.exe”, dbteste.db and slqite3.dll to the directory create in the item 6 above; Which sqlite3.dll? You should use a sqlite3.dll compiled for wince-arm as the one which you can download here: http://wiki.lazarus.freepascal.org/WinCE_Programming_Tips#Pre-compiled_sqlite_dll And you are also placing your dll in a wrong position, please read here: http://wiki.lazarus.freepascal.org/WinCE_Programming_Tips#Current_Directory_and_Placement_of_DLLs Double click in the “browseslqiteprj.exe”. Windows Mobile asks for authorization because my executable is not of known author. I click “yes”. Then I receive the message “'browsesqliteprj' is not a valid Windows CE application” May someone tell me what is the problem? I documented this here: http://wiki.lazarus.freepascal.org/WinCE_Programming_Tips#The_error_message:_SomeProject_is_not_a_valid_Windows_CE_application But in general, as a first step you should try to run the application in the emulator. And only after in the real device. Is there a special DLL to use SQLite in windows CE(or mobile)? Windows CE is not the same operating system as desktop Windows. You cannot just copy a binary from Windows, it needs to be compiled for the Windows CE operating system. This is not only valid for your program, but also for all DLLs which it uses. Is there a way of make windows mobile show lazarus programs execution errors? As they are showed in windows or linux? I don't understand this question, your program hasn't yet started to execute. It error message that you see is generated by the operating system. But if the program had started to run, then exceptions would be shown in message boxes by the LCL. -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] Determining OS
Thank you for the suggestions so far - $ lsb_release seems to give good information, my Fedora 15 machine returns LSB Version: :core-4.0-ia32:core-4,0-noarch In addition, I did a ls of the /etc directory and found a file called system-release-cpe, Looking in it says cpe:/o:fedoraproject:fedora:15 Now, this may be unique to fedora (isn't open source wonderful?), but if all distros have that file, I think that may be the solution, I've got an ubuntu machine running, too - I should look to see what it has. Say what you will about the windows registry, but at least there's a common place to look for and put information. And no, I don't want to start a war over the merits of one OS over another, just trying to make my program portable to the most machines with the least effort for the end user. _ From: ik [mailto:ido...@gmail.com] Sent: Sunday, July 31, 2011 10:55 To: Lazarus mailing list Subject: Re: [Lazarus] Determining OS On Sun, Jul 31, 2011 at 17:43, Graeme Geldenhuys graemeg.li...@gmail.com wrote: 2011/7/31 ik ido...@gmail.com: Please note that system.d is Fedora implementation (v15) so for Linux you need to detect also the Linux distro, and that's a bit more complicated.

[Lazarus] TTabControl (d)evolution
The implementation of the TTabControl seems to cause headaches, and reveals wrong assumptions of the devlopers about the behaviour of that control :-( When I recently submitted an patch, with a new implementation of the TTabControl (named TTabs in the patch), this implementation was tested with the Win32 widgetset, and was fully compatible with the Delphi TTabControl - in contrast to any preceding implementation. Felipe acted a bit too fast, and replaced the TTabControl by the new implementation, without waiting for the complete implementation with all widgetsets. The consequential problems showed up very soon :-( When consequently problems with other widgetsets occured, he removed the intented implementation of TTabs (TNewTabControl), making it unusable at all. This step was undone later. When it turned out that the IDEInspector uses a TTabControl, and stopped working (#19803) due to an misplaced override of ChildClassAllowed, this problem was not fixed in the suggested and obvious way (by moving that method into TPageControl). Instead the wrong assumption was stated, that a TTabControl cannot have child controls - what is not true for a Delphi compatible control. So where are we now? We are back to the old TTabControl, that is not Delphi compatible, and have a TNewTabControl without an designer. Was this worth all the trouble? IMO we should accept that a Delphi compatible TTabControl doesn't exist yet, for widgetsets other than Win32. What can/should we do, when it turns out that such a control can not be implemented in all widgetsets? Why not offer the new implementation (TTabs/TNewTabControl) as TTabControl, to make Delphi migrants happy, and restrict its use to only the supported widgetsets? At the same time the old implementation can be renamed into TLazTabControl, that is not fully Delphi compatible, but immediately usable with all widgetsets? And since the old TTabControl and TNotebook effectively share the same code, except for the control that shows the tabs, it would be a good idea to merge both into a common base class. The difference between both controls is implemented in their Pages classes (TUNBPages, TTabControlNoteBookStrings), so that effectivly only their constructors have to be different, where this object is created. An even simpler solution were to make the tabs switchable ON/OFF. More things can be simplified, in detail the difference between visible and invisible pages, which applies *only* to the TPageControl. By moving that part out of the widgetsets into TPageControl, the implementation of the widgetsets and all TCustomTabControl descendants could be simplified a lot. Then also the restrictions would become more obvious, introduced by the various widgetsets.

I tried this on Linux, with a slightly modified FormPaint event handler,
but the effect is the same as in my example.
When I move the mouse, FPos is changed to the new values of X and Y, but
when Mouse.CursorPos is called using FOldCursorPos as new position,
OnMouseMove is called again, and FPos is changed again to its old position.
Here's my new code:
procedure TForm1.FormMouseDown(Sender: TObject; Button: TMouseButton;
Shift: TShiftState; X, Y: Integer);
begin
if ssleft in shift then
begin
FPos.X := X;
FPos.Y := Y;
FOldCursorPos:= FPos;
Cursor := crNone;
end;

FPos.Y := Y;
Invalidate;
end;
end;

When an individual cell has been zoomed out, all further operations can apply to exactly that cell, regardless of the mouse position.

What can/should we do, when it turns out that such a control can not be implemented in all widgetsets? I bet that it can be implemented in all widgetsets. I don't use TTabControl, so I could be wrong, but I think that you could implement it like this in Gtk2: gtk_widget -gtk_notebook -gtk_widget 3 widgets put together. This should work fine if you can make gtk_notebook show only the tabs without a client area. Another idea: Override all methods which use WS routines and create a handle for TCustomControl instead and custom draw the entire control. Why not offer the new implementation (TTabs/TNewTabControl) as TTabControl, to make Delphi migrants happy, and restrict its use to only the supported widgetsets? At the same time the old implementation can be renamed into TLazTabControl, that is not fully Delphi compatible, but immediately usable with all widgetsets? We cannot have a control in the LCL which works in only 1 platform, if it is really like that, then the current implementation is better. And since the old TTabControl and TNotebook effectively share the same code, except for the control that shows the tabs, it would be a good idea to merge both into a common base class. A very bad idea, they are not even located in the same unit... plus their class hierarchy is not even remotely similar. In fact, I don't see anything common between them. TNotebook many pages and no tabs and no border. TTabControl has 1 page, has border and has tabs. Making unrelated stuff together because they look similar from a first view to save code duplication can bring a heavy penalty in terms of code stability and maintenability. Just think that someone tryes in the future to fix TTabControl and by accident breaks TNotebook... This lesson was learned with the gtk1/gtk2 mess. In fact, I already predict that even sharing code between TTabControl and TPageControl is a huge risk, changes could break TPageControl. The safest would be starting a new WS object for TTabControl ... More things can be simplified, in detail the difference between visible and invisible pages, which applies *only* to the TPageControl. part out of the widgetsets into TPageControl, the implementation of the widgetsets and all TCustomTabControl descendants could be simplified a lot. Then also the restrictions would become more obvious, introduced by the various widgetsets. Why *only* in bold. TCustomTabControl has only 2 descendents, so TPageControl is 50% of it's descendents. -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] RE : Determining OS
Yes, you are definily doing it wrong. You shouldn't even have a installer for Linux. Programs in Linux with installers are just weird... Let the package manager do what a installer would do for you (you can have custom scripts in the package manager if that's strictly necessary, but it shouldn't). On Mac, the most elegant install solution IMHO is to simply copy the Application Bundle to the /Applications folder and that is it. No install necessary, any configuration necessary is created the first time the application runs. But if you really must have a installer for MacOSX I recommend creating a package for MacOSX default installer application. Again you just package everything with a few scripts and that is it. Badilly written custom installer applications is a Windows thing and I'm happy that I don't need to bother with them anymore...

It's easy to provide fully compatible components for the Win32 platform, so why do we offer a very different implementation of the TTabControl, that can not be Delphi compatible by design??? More things can be simplified, in detail the difference between visible and invisible pages, which applies *only* to the TPageControl. part out of the widgetsets into TPageControl, the implementation of the widgetsets and all TCustomTabControl descendants could be simplified a lot. Then also the restrictions would become more obvious, introduced by the various widgetsets. Why *only* in bold. TCustomTabControl has only 2 descendents, so TPageControl is 50% of it's descendents. But 50% of the widgetset code is related only to TPageControl, and makes a TTabControl implementation overly complicated. E.g. a TCustomPage has to be used to transfer attributes to the widgetset, and TCustomPage is related only to TPageControl. When all the tab attributes are moved into an record, then it's no more required that all tabbed controls must create dummy page controls for every tab. And as mentioned above, invisible pages must not be handled in the widgetsets, this can be done exclusively in the TPageControl. When we finally implement a widget with a single client area, that area can be filled with nothing, pages or whatsoever, under full control of the controls. Then we can have a paged notebook again, by simply connecting the tab selection event to an untabbed notebook. Currently the situation is reversed, every tabbed control has to use a TPageControl internally, for the only purpose to show the tabs :-( DoDi -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] The mouse doesn't appears in Windows Mobile 6.5
- Original Message - Which device are you using? It has no touch screen? You attached a external mouse to it? Samsung GT-b7320L Omnia Pro Messenger Phone running Windows Mobile 6.5. No it's a smart phone without touch screen. There is no external mouse. There is a kind of joystick button that acts like a mouse.

Of course. In the pages of the Bradesco Bank or the Banrisul bank I can point the mouse to very different places in the screen and click. After I point to other place and click again and so on.

[Lazarus] Should StringGrid1.Clear clear the fixed rows / columns?
I have a fixed row in my SG with the titles for the columns, but when I do a SG.clear, the fixed rows are deleted. I understand why that is happening (the so-called fixed rows are just row [0] within the SG). However, it would be nice if the fixed rows were not affected by the clear. Am I missing something in the setup of the SG which would prevent the fixed row from being cleared or is this a bug or a potential enhancement request? I could implement something like VirtualStringView/Tree and I am using that elsewhere in my program for another purpose, but I was looking for a lightweight grid. 0.9.31-31292-2.4.4-win32-Vista -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

In the pages of the Bradesco Bank or the Banrisul bank I can point the mouse to very different places in the screen and click. After I point to other place and click again and so on. That does not mean anything ... the browser could have drawn it's own mouse pointer in reaction to VK_UP, DOWN, LEFT and RIGHT (Key down events). At least Opera Mobile and Opera Mini do that! If the device has it's own non-standard mouse pointer you will even see two pointers sometime, a device pointer and the one created by the application. It should be possible to do that in your own application, but I don't know if it is possible to do that and still use native controls. For a browser this is not a problem, because the browser is composed almost entirely by 1 custom drawn control ocupying almost the entire screen. If your app is similar, you can draw a mouse pointer limited to your drawing control. -- Felipe Monteiro de Carvalho -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
