IMHO ptrint is the wrong choice. it invites to write code that can not be ported. and leaves unreadable LFM. If streams use int64, and this is for the purpose of copy those values, then it must be int64 too (or qword, if it can't be negative ,and should have the full range). -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Ins any case, the range must be a type, that has the same size on all Platforms (Int64 is ok / ptrint is not). Using a variable size type will create problems for any project that is cross platform and developed by a team (it be a question of time until some team member on a 64 bit system uses a value, that does not compile on 32 bit). The reason given in the issue IMHO is in this case not valid. And without reason, it is harder to make the right decision. It (int64) must be supported, because the OS could accept it is no reason in itself. In this particular case there is no functionality gained. Most of the time if an OS accepts some value (or a greater range), this will also add functionality. This is not the case, when the limit (set by the screen) is below the sub-range already used. The only reason I see, is that user code can use TStream values without having to scale them in the user code. (scaling still happens, either in the LCL, or OS, or both) So the question is what is more important. - For the few cases, were it is used with tstream the user code will be simpler. - For all other cases user code stays as it is, but there is more code to maintain in many widgetset's code (adding maintenance). My guess is that Delphi may have that because of those visual-binding stuff. So if one wanted to link TProgressbar.VAlue to TSomeFileOrStreamHandlingComponent.Position, and want to do that in the form designer (which from the videos embarcadero publishes, apparently can be done), then for embarcadero it is much easier to create the code for the visual bindings. If the requester wants to contribute something of that kind: cool. Otherwise lets see if there are other (valid / based on functionality affected) reasons. Or if it is only simplifying the occasional code using TStream (which still can be reason enough) -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Re: [Lazarus] TCustomControl.Autosize issue (umlcat)
I can't find code responsible for that in TCustomPanel. Any tips? Most Lazarus libraries are not a single *.pas unit file, like Delphi, since the controls are implemented for several platforms visual control libraries. So, you may have a *.pas file that references several *.inc include files. Look for your FPC or Lazarus source code files. Search for *.inc files. Reason is delphi compability? I agree that it can be messy, but, Delphi compatibility its also importanty, since a lot of developers here, have apps, originally builted in Delphi. I also have tried to (re) built some visual controls from scratch, and copied or based some code from existing controls.

Re: [Lazarus] Tprogressbar and positional info under Windows
Ok, After looking at MSDN and the widget source code under windows, I assert there is presently an un-exposed flaw. There is data precision truncation via Line 671 of unit ./lcl/interfaces/win32/win32wscomctrls.pp. Where NewPosition is Integer and under windows Integer is LongInt not Word. According to Microsoft's Developer Network Page PBM_SETPOS, PBM_SETRANGE only support signed integers up to 65,535. So, that means that there is a clear problem here. And a general case solution is easy to form. The best possible route would be to allow the largest Integer type and scale inside the lcl. Next question would be, can the IDE property streamer handle Int64 values? If not, what's involved with expanding the property reader. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
