Actually, it doesn't make a difference. The thing that fooled me is that

That said, changing the frame to gtk_alignment_new(0, 0, 1, 1) seems to
work for me. What does it look like on Ubuntu?
Henry, works correctly in Ubuntu, looks like a good candidate. At
least it hasn't bad history of the scrolling control so maybe also
fixes the same problems. But I still can not catch OnPaint from all 3

understand what was that fix (#19488) about.

Is it possible for LCL-Qt to have horizontal text too, like LCL-GTK2? At least just for the IDE? After compiling my IDE for LCL-Qt I was forced No, Qt paints tabs and text position depends on theme (if some theme have horizontal text in right aligned tabs).

Lets hope that Qt 5's default graphics engine that requires OpenGL and forces developers to use Javascript instead for app development, doesn't affect desktop application developers too much. At least there is a mention of the QWidget-style API still hanging around for some time - but not there main focus any more. Good news is that at least this time they are going to try and make the upgrade from Qt 4 to Qt 5 less painful (remember the move from Qt3 to Qt4?). So the Lazarus LCL-Qt developers should be happy with that. I don't like some things in Qt too, but it's still better then gtk2/3, also Qt5 won't kill desktop and QWidget philosophy. Upgrade from Qt4 to Qt5 won't be a PITA (like with Qt-2/3-Qt4), since there won't be huge changes with 2D graphics system (QPainter) and QWidget's. Only good thing in Qt5 is introducing of QAfterPaintEvent (if they implement it ... it was planned by trolltech devels). Anyway, it will stay opensource so I'm not scared about it's future.

On Saturday 22 of January 2011 16:04:34 Michael Van Canneyt wrote: On Sat, 22 Jan 2011, Hans-Peter Diettrich wrote: In fpGUI Graeme implemented an interface for inter-process dragging. It would be nice to have a similar interace in the LCL, that extends the current intra-process dragging. While it is correct that Graeme did this, I still have not seen in action. i.e. I have used the application-specific DnD, but I wouldn't know how to handle the intra-app DnD. Why that? - A more general approach could solve the known problem with docking forms, by including dragging by the window manager. - Drag-drop of files or other objects as an alternative to an OpenDialog. - Embedding of shared objects (COM, CORBA...) What's required? - A generalization of the DragManager, so that visual (DragImage...) and application feedback (events) are not restricted to application-internal drag sources and implementations. This is not hard to do, all that can be handled in the already existing or added specialized DragObjects, instead of the (superfluous) DragPerformers. - A DragObject should include a SourceType property, so that the targets can handle more source types, e.g. filenames or COM/CORBA objects, in addition to controls. Mime types (strings or enum) can be used for that purpose. Further information for inter-process dragging can be added (source PID, HWND...), so that an application can distinguish internal references (to controls...) from references to objects in other processes. - The event handlers must have access to the extended source information. This is also no problem, since only one drag operation can be active at any time, so that a global DragObject reference can be used everywhere. A predefined DragObject can be used whenever an external object is being dragged over an application form. - More drag and drop types should be defined, in addition to drop and dock, e.g. open files, link or embed. Eventually specialized drag targets must register themselves, for e.g. accepting files or embedding objects, in addition do DockSite registration. I'm all for it. Although I'm not sure that this can be implemented in a cross-platform way. On Windows, the intra-app drag/drop is handled using OLE/DDE. On Linux, there is no such thing, and I think it depends on the used desktop software (KDE vs Gnome). I don't know how it is done in Mac. But your suggestion is at least a step in the right direction. I would implement support in 2 objects: TFileDragObject (external files, as dropped by file managers) TExternalDragObject (external app DnD) Both are created whenever an external DnD is found. Files dropping is already implemented, and I'm pretty sure that Qt supports DnD across different apps on all platforms.

What's unclear here ? That we have TWinControl instead of TWidget ? If Bo goes to his system supplier and asks which widget set is installed and they ask what he means, he isn't going to get very far by starting to talk about TWinControl etc. Instead he needs to say something along the lines of what's on there- GTK or Qt, and what version?.

I suppose I should report an issue, but just wondering, is it hard (if it full reproducible) to run another instance of Lazarus and debug it, so the report could contain more information saving the developers' time? Or at least recompile it with an option allowing to show additional information about the error , not only simple access violation message? What widgetset ? zeljko -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Turn a TGroupBox into a TPanel

Under GTK2, the TPanel still have some annoying bugs. If we had in TGroupBox a property HideContourLineWhenCaptionIsEmpty or even HideContourLine, the TGroupBox could replace TPanel in the poor man's layout manager role. [1] http://wiki.lazarus.freepascal.org/Autosize_/_Layout No, we cannot do that since there's no property in GtkFrame to do such thing. Under gtk2 TPanel is scrolling control because GtkFrame is wrong class (wrong gtk design IMO).There should be pure GtkFrame (like it is eg under qt) and GtkGroupBox (which is current GtkFrame). Only way to fix this is to write an gtk2lcl class which should be like qt's QFrame , and of course use that class instead of scolling controls. zeljko -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Need testers (gtk2)
Hi, I've commited an important patch today (r 27829) , about gtk2 main loop iterations. Now it uses g_main_context instead of g_main which is deprecated from gtk2-2.2. This patch improves main loop, but also now PostMessage() works fine for messages from another threads. *** Gtk2 Laz/LCL must be build with -dUSE_GTK_MAIN_CONTEXT_ITERATION *** to get this new code work. If you find any issues about it, please open it's # at bugtracker. After while I'll set USE_GTK_MAIN_CONTEXT_ITERATION as default, so -d won't be needed anymore. I've tested under: Fedora 3 (gtk2-2.12), Fedora 13 (gtk2-2.20), Ubuntu 10.4 64bit (gtk2-2.20). Gtk2 version isn't important here, but glib2 version is, so if you open any issue about main loop problems, please provide next informations: 1.Linux distribution version + 32 or 64 bit 2.Gtk2 version 3.Glib2 version. 4.Provide an simple example where I can reproduce your problem. thanks. thanks zeljko -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

In my short tests it works well. I didn't notice difference for older versions. I will try PostMessage later. This update is mostly commited because of PostMessage() :), but also affects unthreaded apps, because our message queue does not rely on critical sections, but parallel g_main_context, which is more effective in multi threaded environment. $ gdb framedem --sync which says: gdb: unrecognized option '--sync' Use `gdb --help' for a complete list of options. I can give the parameter in Lazarus Run Parameters... but then the whole Lazarus freezes. It doesn't take mouse clicks and must be killed. Isn't standard X11 param with one - eg. ./myprogram -sync ? zeljko -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

And yes that page automatic features is another place, where no one ever would expect anything (half of it is display related, and should be on a page nested into display) = for the rest: a good name is needed (maybe the hints can even get there own page...)
