[Fxruby-users] FXList#makeItemVisible and ruby threads

[Joel V. <vj...@PA...>]

I'm updating a FXList from a thread, and I'd like to
always scroll to the last item. This is what I tried:

require 'fox'
include Fox

app = FXApp.new("List", "TEST")
win = FXMainWindow.new(app, "list")
list = FXList.new(win, 10)
Thread.new do
   20.times do |i|
     list << i.to_s
#    sleep 0.1
     list.makeItemVisible(list.numItems-1) # no effect
     sleep 0.1
   end
end
win.show
app.create
app.run

As it is, the makeItemVisible has no effect, immediate or delayed. 
However, if I uncomment the first sleep, it has an immediate effect, as 
desired.

Does that make sense?

Thanks Sander,

I tried this and it works perfectly, just for reference here's the ruby 
code, to make it work:

-----------------------------------
require 'fox'
include Fox

img = nil

FXFileStream.open("image.bmp", FXStreamLoad) do |stream|
        img = fxloadBMP(stream)
end

FXFileStream.open("image.jpg", FXStreamSave) do |stream|
     fxsaveJPG(stream, img[0], img[1], img[2], img[3], 100)
end
-----------------------------------

Cheers,
Carsten.

Carl,

I think we are spinning our wheels at this point ;)

Can you please send me running code that demonstrates the problem, and I 
promise to take a look at it this afternoon. At this point I think it's 
best that I see the program instead of a code snippet, just in case 
there's something else going on that is a problem.

Thanks,

Lyle

Re: [Fxruby-users] FXProgressDialog problem

[Carl Y. <ca...@yo...>]

I tried adding app.flush and app.forcerefresh after I show the progress 
dialog but nothing seemed to change.  I see only the pie chart, since it 
is being updated, and the rest of the dialog doesn't show up until the 
operation is over.  I figured that maybe I needed to call forcerefresh 
or flush on the FXProgressDialog itself, but it didn't seem to have 
these methods.

I think that show(PLACEMENT_OWNER) should do that, see:

I can't believe this, but no, it appears that in FOX 1.0 you're stuck 
with the "piechart" format for the progress dialog. Looks like this is 
fixed for FOX 1.2, but that doesn't help us at the moment. I think your 
only workaround would be to roll your own custom dialog box with a 
regular FXProgressBar inside it.

As for the window decorations, instead of this:

     PROGRESSDIALOG_NOCANCEL

try passing in this:

     DECOR_TITLE|DECOR_BORDER|PROGRESSDIALOG_NOCANCEL

Hope this helps,

Lyle

Re: [Fxruby-users] FXProgressDialog problem

I spoke too soon.  It is plain white because it doesn't have a high 
refresh priority while my application is chugging away doing it's own 
work.  Is there a way I can give it a higher priority to make sure it 
gets painted properly before I begin my work?  And I also want to change 
the bar to be horizontal instead of pie shaped.

Thanks,

It worked!  Except it just appears plain white with no normal window 
style and a piechart with a percentage.  Is there a quick way to get a 
more conventional progress dialog?  I want a modal dialog box with a 
title, some text below it, and a horizontal bar that moves from left to

Re: [Fxruby-users] Converting Image Formats

[Sander J. <sx...@cf...>]

Lyle,

I don't think that will work, img is still a FXBMPImage. What you really =
want=20
to do is call (the ruby alternatives)

fxloadBMP(parameters);

and=20

fxsaveJPG(parameters);

You don't need the image class if you're not going to show it on screen.=20

Good question (and the answer is yes). Load the BMP image from a file 
using code like this:

     img = FXBMPImage.new(getApp(), nil,
         IMAGE_KEEP|IMAGE_SHMI|IMAGE_SHMP)
     FXFileStream.open("image.bmp", FXStreamLoad) do |stream|
         img.loadPixels(stream)
     end

and then save it as a JPEG using code like this:

     FXFileStream.open("image.jpg", FXStreamSave) do |stream|
         img.savePixels(stream)
     end

Hope this helps,

Ah, my bad. What I should have said was add these *two* lines at the 
beginning of the block:

	prog.create
	prog.show

Let's see if that does it!

I tought that was the case. I don't really feel like I need rbtree at this
point. (today at least, tomorrow, who knows ;^) )

Yeah, I know its early still, but it looks like it is working mostly right,
its just the business of adding nodes at run time that I can't get to work.
It is likely because I am not doing it right. I can't say that I really
understand how your stuff works yet, not at the intuative level that I want.
I am pleased with it, but I really do not have it under my belt yet. ;^)

I will keep working on it, I was just hoping for some ideas.

Hi all,

is it possible to load a BMPImage and save it as a JPEG, just by using 
the FOX library? I couldn't find this out by looking at the API.

Cheers,

Ouch, wasn't aware of that. Next time I release FoxTails, I'll see if I 
can build a windows binary of rbtree and make that available. I can't 
seem to find a binary in the usual places, like 
http://ftp.ruby-lang.org/pub/ruby/binaries/mswin32/. I notice that no 
one has voted for it at 
http://www.rubygarden.org/ruby?WindowsInstallerVote, so maybe we can't 
expect it in the installer any time soon.

Well, I'll take a look at it, but the tree stuff in FoxTails 0.2 is 
sorta pre-alpha, so don't expect much to really work correctly...

[Fxruby-users] FTTreeLike problems

[Will M. <wi...@co...>]

Joel, (and everyone else)

I have been trying out the Treelike stuff in your new Foxtails release. The
first problem I noticed is that your fancy tree example requires rbtree
which does not have a windows version. Since I don't feel up to trying to
figure out how to make it work on windows, I can't test it.

The second problem seems a little more aggravating. Using the tree.rb
example I am creating a tree list on one window. Everything works fine for
the stuff that I add inside the create methods.

The problem comes when I try to add a new node after the create process is
complete. I get a error message that reads:
  Please report this bug:
  This FXTreeItem * already released
    In Observer when value of variable `child_joins_parent' matched pattern
Object
    In Observer when value of variable `tree' matched pattern Object
    In Observer when value of variable `targetObject' matched pattern Object

(Note that the last two things listed are variable names in my program, but
the first is not and I can't make sense of any of it.)

I can change various things and get various different variations on that
error message, but I can't get it to work.

How should this work?

PS, I am including some code below. This will look familiar, but it has the
FTTree stuff added.

Thanks for sharing this, Joel. It's also perhaps worth pointing out 
that this approach works for the more general case of just popping up 
any kind of dialog box. For example, to show a file dialog:

	require 'fox'
	include Fox

	FXApp.new do |anApp|
	  FXMainWindow.new(anApp, "") do |theMainWindow|
	    anApp.create
	    puts FXFileDialog.getOpenFilename(theMainWindow, "Pick a file, any 
file", Dir.getwd)
	  end
	end

happened, so there's nothing to close). Apologies if this is common 
knowledge...

require 'fox'
include Fox

app = FXApp.new
win = FXMainWindow.new(app, "")

app.create

FXMessageBox.error(win, MBOX_OK, "caption", "message")

Actually, even though I hadn't shown that in the code I sent to you, I 
had tried that (calling prog.show after instantiating it) and it still 
doesn't work.

Thanks,
Carl

Well, never calling show() on the dialog box is a problem ;)

See what happens if you add the line:

	prog.show

as the first line of the block. Also I guess a call to prog.hide at the end.

[Fxruby-users] FXProgressDialog problem

[Carl Y. <ca...@yo...>]

I'm trying to display a progress dialog after the user clicks a button.  
In my onClick method for my application, I have the following code:

FXProgressDialog.new(self,
                     "Bayesian Inference Progress",
                     "Learning Bayesian network",
                     PROGRESSDIALOG_NOCANCEL) do |prog|
   prog.total = @transactions.size - total_categorized + 120
   prog.progress = 0
   # stuff ...
   prog.progress += 10
   # more stuff ...
   prog.progress += 10
   # etc. etc.
end

When I click on the button, the code gets executed but I never see the 
progress dialog.  What am I doing wrong?

Thanks,

Carl Youngblood

Re: [Fxruby-users] Frames not obeying width/height?

[Sander J. <sx...@cf...>]

Probably not since Scrollframes (like a iconlist) have a default width of=
 1.

I tested it with another frame inside the right frame, which had a list 
control inside of it.  Does this count?

Thanks for the info.

Re: [Fxruby-users] Frames not obeying width/height?

[Sander J. <sa...@kn...>]

What you probably want:

Left Frame - needs to take up as much space as possible - >  
LAYOUT_FILL_X|LAYOUT_FILL_Y

Right Frame - Only needs to take up space that it requires, though we want to 
take as much height as there is ->  LAYOUT_FILL_Y

Now... the size of the right frame is determined by its contents. If you don't 
put anything in there the width will be 1. So make sure if you test it, you 
put something in there (like a button for example). 

If you really insist on having a fixed width (bad practice, fonts may change 
size and some things won't fit anymore), you have to pass the 
LAYOUT_FIX_WIDTH or LAYOUT_FIX_HEIGHT and pass the required size in the 
constructor of the widget (or later using setWidth or setHeight).

Note, you can leave the LAYOUT_TOP and LAYOUT_LEFT since they don't influence 
anything here. 

Also read the documentation on layout managers:

Hope this helps,
