Here is what I've come up with so far: http://gist.github.com/105742 It is nowhere near finished, and some things like the return values of on_data, etc. are just there to get it going. I sort of expected the image to be part of the "cursor" when you do the drag-and-drop operation, like what you get when dragging from the OSX Finder, a representation of the file, while dragging. But, all I'm getting is an empty square with a pointer. Is that all you get by default, or am I doing something wrong? I thought maybe the image was too big, so I scaled, resized it down to smaller than the square, but still just got the empty square. I originally thought I was going to use a Wx::DragImage, but it turns out that DropSource#do_drag_drop blocks mouse events, so trying to incorporate the DragImage sample doesn't work because evt_motion doesn't get triggered while do_drag_drop is active. Now I'm thinking of using DropSource#give_feedback in conjunction with DragImage, but give_feedback doesn't give you mouse coordinates, so to do that, I need to find some way of grabbing the mouse coordinates within give_feedback so I can tell the image where to move. At this point, what I'm thinking seems way too complicated and that is usually a signal to me that I'm doing something wrong, so I want a sanity check from the experts. Again, any pointers is the right direction would be appreciated. BTW, if you actually want to run the sample, you'll need wxruby-logo.png found in the samples/drawing directory under the wxRuby distribution. I didn't think it was a good idea to try to post that in the Gist. -- Posted via http://www.ruby-forum.com/.

Probably the easiest one for this situation - where you have a job that breaks down naturally into smaller pieces (individual files) - is to use evt_idle. This is called whenever there is processing time free. It would go something like this: def initialize ... evt_idle :on_idle end def on_idle if have_files_to_copy copy_a_file update_progress_bar end end This should allow the task to progress in chunks while keeping the GUI responsive. A more general approach to dealing with long-running tasks is to run them in a background Thread. But this is considerably more complicated for several reasons - eg you should not make GUI update calls from subordinate threads. There are previous discussions and samples about using Threads in wxRuby if that's the way you want to go. alex From lists at ruby-forum.com Mon May 4 15:41:33 2009 From: lists at ruby-forum.com (Jonah Dahlquist) Date: Mon, 4 May 2009 21:41:33 +0200 Subject: [wxruby-users] Gauge use In-Reply-To: <49FF37AF.6050000@pressure.to> References: <20090503232134.EF9381858102@rubyforge.org> <49FF37AF.6050000@pressure.to> Message-ID: <927ec38eb9b61fe7f89241bb54eb509d@ruby-forum.com> Perfect!

I'm no expert on this, but I would have expected this not to be too hard. However, other people using WX seem to be wondering the same thing.

With ruby1.9.1p0, I haven't noticed such kind of problems on Ubuntu 8.10 and wxRuby-2.0. I have upgraded to Ubuntu 9.04 recently, and I just run the test case still with ruby1.9.1p0 and wxRuby-2.0 without any problem. Conversely, on my MinGW installation, I have upgraded to ruby1.9.1p129 and I've noticed that the corresponding wxRuby-2.0 binary gem (built with ruby1.9.1p0) does not work at all. I've just rebuilt the wxRuby-2.0 lib with ruby1.9.1p129 and then everything works again. Can you try to rebuild wxRuby ? Anyway, I will check soon what I suspect on Ubuntu 9.10 : - upgrade to ruby1.9.1p129 then try your test case with the wxRuby-2.0 binary gem : the error at the exit should occur - rebuild wxRuby-2.0 for ruby1.9.1p129 and see if the error doesn't occur any more.

I've worked up a basic DragResultHandler, it would be nice if some form of this were included in wxRuby. Line 49: I don't get a sunken border on Windows. It looks nice on OS X, but Windows just has a flat featureless plane for the drop targets. Lines 89,95: I don't have to call refresh on OS X for the backgrounds to light up, but Windows doesn't do anything unless I call refresh. Is this expected? Line 131: This doesn't work on Windows or OS X. I get a "Wrong Argument" error. It looks like the documentation says you should be able to do this, but I've tried several permutations, and none of them works. Lines 155-158: On Windows, the give_feedback method is only called consistently when the pointer is over the drop targets during a drag operation. It is called intermittently when over the drop sources, and not at all anywhere else. This works perfectly on OS X. Line 179: This is like trying to create a new image on line 131. The documentation seems to say I should be able to do this, but it gives me an argument error as well. Resorting to setting the alpha pixel-by-pixel as I do on 181-185 works, but it is ugly. Lines 189-195: I expected to just set the hotspot to half the width of the image, and the full height of the image to get the image floating above the cursor. This just doesn't work. I have to use these non-sensical values to get the effect I want on OS X. On Windows, the result is inconsistent, sometimes I more-or-less get the effect I want, and other times the image is way off to the side and down from where it should be, and other times it is way off to the side and up from where it should be. Line 202: Works perfectly on OS X. On Windows, after I drag/drop one image, and I then attempt to drag another image, if I move the pointer around "too much" the program segfaults at this line. I can drag the image around all I want on the first drag operation, but the second one always segfaults when I move the pointer around "too much". Line 209: As with the other mention of refresh above, I only have to call this on Windows. Seems like I shouldn't have to call it at all. Lastly, a problem on OS X is that after a drag/drop operation, and clearing the dialog, I have to click once anywhere in the window before I can initiate another drag/drop. I thought it might be a focus problem, so I tried different methods of resetting the focus, but it doesn't seem to make a difference. If I don't use the MessageDialog, that is, I just replace the dialog with a 'puts' in the event handler, I don't have that problem. This is only a problem on OS X. Again, I'm unsure if I'm doing something wrong, or if these are bugs in wxRuby, any pointers would be much appreciated. Just a quick note on the Gist, you may notice I've included the image in it now so you don't have to go grab it from somewhere else. Also, if this helps, on OS X, I'm using wxRuby 2.0.0, ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-darwin9], built from ports, and on Windows I'm using the same version of wxRuby and ruby 1.8.7 (2008-08-11 patchlevel 72) [i386-mswin32], which I downloaded from the Ruby website. Since I'm going to use my template for packaging/distribution, using a different ruby version wouldn't be that much of a problem. Oh, and I'm running Windows under Parallels 4 on OS X for these tests, if that makes a difference. Thanks! DZ -- Posted via http://www.ruby-forum.com/.

' I would translate it this way: "The given procedure wasn't found". At the same time I get a Windows error window, saying: Der Prozedureinsprungpunkt "DLLMain at 12" wurde in der DLL "msvcrt-ruby191.dll" nicht gefunden. I don't know how to translate "Prozedureinsprungpunkt", but it must be something like "procedure definition point", so I would say: The procedure definition point "DLLMain at 12" wasn't found in the "msvcrt-ruby19.dll" DLL file.

Every time I try I get an error that > says that Windows isn't able to find some procedure. I had exactly the same problem when I upgraded my MinGW ruby-1.9.1 from p0 to p129. I suspected a general binary incompatibility between these two versions of ruby (see http://rubyforge.org/pipermail/wxruby-users/2009-May/004862.html). But this seems to be specific to MinGW. The solution is to rebuild wxRuby-2.0 for the ruby-1.9.1-p129. If you can't rebuild the gem yourself, please wait for the upcoming wxRuby-2.0.1 release. The MinGW wxRuby-2.0.1 gem will be built for ruby-1.9.1-p129. Cheers. Chauk-Mean.

OK, so I'm going to wait for that release. I thought, I made something wrong with updating my Ruby installation... :-) Thanks! Marvin -- Posted via http://www.ruby-forum.com/.

I guess the workaround is to only use drag images in OSX. Kind of disappointing, but oh well, everything seems harder in Windows, and it's not the fault of Wx. I wonder what GTK is like. -- Posted via http://www.ruby-forum.com/.

Would that mean that wxRuby could run on MacRuby, and we could get real compiled applications, obviating the need for crappy frameworks like mine (http://github.com/duskhacker/ruby_on_skis/tree) for distributing ruby applications? That would be a great improvement, since "collection" frameworks like Ruby on Skis, Script2Exe and others still don't address the code obfuscation that most companies would require to sell applications.
