I agree with you, but it's not my forum to shut down. :) I don't have
the bandwidth to monitor the Internet for all of these little
discussion pockets. This mailing list has always been (and continues
to be) the place for FXRuby chatter.

Per the message found by Joey Kinsella (elsewhere in this thread) it
sounds like the documentation for FXTopWindow needs to be corrected to
reflect the fact that you only get SEL_MINIMIZE, SEL_MAXIMIZE,
SEL_RESTORE and SEL_CLOSE when you call one of those FXTopWindow
methods (e.g. FXTopWindow#maximize); otherwise you just get
SEL_CONFIGURE. I'm not sure why the documentation wasn't corrected
when that problem was originally reported.

Leslie, could you please file a bug report on this on the new bug
tracker at Lighthouse?

Thanks,

As posted here:

http://old.nabble.com/programmatically-%22pushing%22-a-button-td14403676.html

It appears that when a user selects Maximize or Minimize it actually sends SEL_CONFIGURE.

Hope that helps.

[ANN] FXRuby 1.6.20 Now Available

2009-11-09T14:43:18Z

All,

FXRuby version 1.6.20 is now available for download.

This release is primarily a transitional one, intended to prove out
the significant changes to the development environment. Earlier this
year, the FXRuby source code repository was moved from Subversion
(hosted at RubyForge) to Git (hosted at GitHub). More recently, I've
revamped the build system, replacing some custom scripts with a more
standardized process based on the Hoe and rake-compiler extensions to
Rake. The intent of these changes is to make it easier for interested
parties to participate in FXRuby's development. As a result, despite a
good bit of code churn, there are (by design) no significant
functional differences between this release and version 1.6.19. For a
summary of the changes in this release of FXRuby, please see this
page:

http://www.fxruby.org/doc/changes.html

Enjoy,

Lyle

Not as far as I know.

When you assign an icon image to a widget (usually a label or button),
FOX will honor any regions identified as fully transparent in the
image. For PNGs, it uses the alpha channel to identify regions where
alpha is zero; for other image types it can guess the transparent
color or you can specify it explicitly.

You aren't missing anything. All you can achieve with the table, short
of maybe subclassing it and overriding the drawing behavior, is set
alternating cell colors.

because of this error think i had tried other variations as per my original email to you.

have also tried aTimer = addTimeout.new and also added in a require 'timeout' statement into the program just in case i had to add in the file without realising it from documentation.

Now i've tried something a bit left field.

this is my thinking be it right or wrong...

because the error shown implies there is NO object created i added this in the unit test code...

#unit test
if __FILE__==$0
require 'libGUIb16'
app=FX::App.new
w=Fxwindow_code.new app
w.topwin.show(Fox::PLACEMENT_SCREEN)
@aTimer = app.addTimeout.new<<<< in case i needed to create the object 1st.
app.create
app.run
end

now i have this code

giving me the error below...

have tried replacing the {} with DO and END but got an error $end expected.

tried brackets but got unexpected () encountered.

could you send me a work piece of code?

like a listbox , toggle button

push button and timer is started, after timeout text apended to the listbox, push button again and timeout is removed?

that way i can see what errors i get (esp if you wroked sample fails).

Timer control

2009-11-01T23:51:01Z

Was wondering if anyone could via small piece of code show how a timer is envoked.

Sometimes (at least for me) a worked sample (with some documentation) is better than having something explained in words.

I would be grateful,

On Moving Away from RubyForge Services

2009-10-26T14:46:26Z

All,

As some of you may have heard, the default gem hosting repository will
soon transition away from RubyForge.org to a new site, RubyGems.org
(aka Gemcutter.org). Coincident with this transition will be a gradual
(?) phasing out of other RubyForge services, which I've written about
here:

http://lylejohnson.name/blog/2009/10/26/wait-what-was-that-last-bit/

As I write near the end of that piece, I'm starting to think about
where some of these services (namely, FXRuby's bug tracker and mailing
list) should land after the dust settles. I list a couple of
possibilities in the blog, but I'd like to open up discussion here as
well for anyone who has opinions and experiences to offer. So, chime
in as you feel led!

Thanks,

Lyle

Tabbook tabitem controls

2009-10-25T03:06:13Z

Hi,

(note - I use foxGUIb for the GUI placement of controls)

had a an issue with the tabbed books control - namely after working on the 1st tab for most of the time i am now at a point where i can move onto the 2nd tab.

To reduce the amount of code sitting inside init of my event handling program i moved a lot of methods i'd written to another file.

I then proceeded to work on my 2nd tab with regards to creating the event hooks, BUT found that event my calls to
another file that had worked perfectly failed! plus my calls to methods in my newly created file failed.

but when i got back to my 1st tab things worked again - NO PROBLEMS NO CRASHES! even calls to methods within the same file as my event code failed.

All these said that there was no method...

Tonight i added these lines...

#@PStabitem2.shown = true
#@PStabitem2.enabled = true
#@PStabitem2.visible = true

then things started to work, so i uncommented a method i had created and things worked, so i then copied the code and put them in another file (one i created when i started work on the 2nd tab) and the calls passed no problems.

So as an exercise I commented each line above to see what the change was but the code worked even with all 4 lines commented as i show then above the code works.

what gives?

I actually created another file deleting all references the controls etc associated with the 1st tab.
Even this didn't help my problems and I'm wondering if there is a "bug" that isn't mentioned in the API?

I mean I would have thought that if one clicks on a tab then within the code it would have a method at least to say activate (mean although you see the controls they need some primer work done so they act as expected).

If anyone can give me an explanation on why I've had this problem I'd be grateful.
I've googled, api'd forumed for a week now any only got it going by a fluke!

Also i can't use any of the codes in keys.rb.

wanting to use function keys like F11 and F9 but i cannot do this as expected...

ACONTROL.connect(SEL_KEYPRESS){
   if keycode == KEY_F9          Do know that the keycode is an error but i didn't know at first.
     do something
   end
}

Now i had come across a posting from Lyle saying you used event.code to trap the keypress value.
so i tried doing a puts "key pressed = #{event.code} was" type statement but it failed with errors

I do understand foxGUIb hasn't got the best documentation but would have thought this would've been somewhere in the fxruby forums before now.

Henon has helped be over this problem (but i cannot detect F key presses) in so far as i have this....

ACONTROL.connect(SELKEYPRESS){}a,b,event|
if event.code = '97'
    do something - I cannot trap with KEY_a or any other constant in KEYS.rb
    F keys - I use theinteger values and use them in code - not the best.
end
}

again WHY?

where is the error code when i use KEY_ defined in keys.rb file.
I don't require the file in code (and when i did try this earlier in the day it still didn't help - even with using extend statement.

>rubyw mymainwin3.rbw
mymainwin3.rbw:39:in `init': uninitialized constant Fxwindow_code::KEY_Escape (NameError)

    from mymainwin3.rbw:82

and here is the actual code snippet - I was using the numbers (currently commented out to the left and it worked)

        when KEY_Escape #65307 #Escape key pressed

           change_radio_status 4
        when KEY_F5 #65474 #F5 pressed
           change_radio_status 2
        when KEY_F1 #65470 #F1 pressed
           change_radio_status 1
       end
    }

It took a little experimentation, but I think I've got it working. I
replaced the previous copy of the gem in my Dropbox with a new one
built with Xft support; for reference, the link is:

http://dl.getdropbox.com/u/60906/FXRuby-1.6.20-universal-darwin-10.gem

Make sure that you uninstall the gem you previously installed:

sudo gem uninstall FXRuby

and then download and install this new one. Let me know how it goes!

Ah! This is good information. Yes, I'll check into that and see what
needs to be done. Thanks for the feedback, and I'm glad to hear that
the gem basically works!

I gave the new Snow Leopard friendly gem a whirl on my newish MacBook
Pro, and an older MacPro tower. Both installations went fine, and I
was able to execute my applications and FoxGUIb, without any issues
save but one minor thing:

The MacPorts installation that I have produces anti-aliased text in
all of the widgets, but the gem does not. I'm guessing this has
something to do with a FreeType library installation or something, but
it if doesn't bloat the gem much, that might be a good thing to include.

Why don't you try downloading that gem, then type

If you have something for linux then i'd be happy to test it.

I don't have anything precompiled for Linux, but I guess I could try to put something together. The problem is that there are so many variables that come into play with Linux, and I'm not sure which ones of them are significant. For example, I know that it matters which version of Ruby you've installed (FXRuby built against Ruby 1.8 won't work with Ruby 1.9, and vice-versa). But I don't know if it matters, for example, if I'm running Linux kernel version X and you're running Linux kernel version Y, etc.

You may have figured I'm not the brightest light bulb in the pack when it comes to ruby but I do try to sort issues i have out before posting and then i carry on trying.

I use Meinrad's foxGUIb front end and find it BLOOD great as i can easily knock up a GUI front end quicker and get a visual look quicker than i can with FXruby natively (plus i find i get confuse about the FXruby code.

personally would love to see foxGUIb worked on some more to make it easier to add controls that someone like me could add to _or_ to add new controls like the fxtable (know this won't happen and i haven't got the skills).

Maybe you don't have the skills right now, but I bet Meinrad would appreciate it if you made an effort to get more involved contribute back to the foxGUIb project (and maybe you already have, I don't know). Have you ever poked around in the foxGUIb source code to try to figure out how it works, and then try making little changes to see how they affect things? That's a good way to start dipping your toes in. ;)

I run Kubuntu 9.04

OK, I do have a virtual machine with Ubuntu 9.04 around here somewhere. I will try to put something together and we'll see if it works.

Re: Pre-release FXRuby binary gems for testing

2009-10-20T23:18:34Z

Lyle,

If you have something for linux then i'd be happy to test it.

You may have figured I'm not the brightest light bulb in the pack when it comes to ruby but I do try to sort issues i have out before posting and then i carry on trying.

I use Meinrad's foxGUIb front end and find it BLOOD great as i can easily knock up a GUI front end quicker and get a visual look quicker than i can with FXruby natively (plus i find i get confuse about the FXruby code.

personally would love to see foxGUIb worked on some more to make it easier to add controls that someone like me could add to _or_ to add new controls like the fxtable (know this won't happen and i haven't got the skills).

I run Kubuntu 9.04

cheers,

Dave

Subject: [fxruby-users] Pre-release FXRuby binary gems for testing

All,

A couple of new build platforms have come into the picture since the last FXRuby release and I'm trying to make sure they're supported. That is to say, I want to be able to provide precompiled binary gems so that users on those platforms don't have to build everything from source. I think I'm there, but I could use your help testing if you have access to either (1) the new, still under development MinGW-based Ruby installer or (2) Mac OS X Snow Leopard.

Here is a binary installer for FXRuby 1.6 on Ruby 1.8.6, the MinGW edition (the one being developed by Luis Lavena and co.):

http://dl.getdropbox.com/u/60906/FXRuby-1.6.20-x86-mingw32.gem

And here is a binary gem for FXRuby 1.6 on Ruby 1.8.7, the one that comes with Snow Leopard:

http://dl.getdropbox.com/u/60906/FXRuby-1.6.20-universal-darwin-10.gem

If you have the time and are willing to be a guinea pig, please download and give it a short (and let me know how it goes). Remember, the goal here is that the end-user doesn't have to have any of FOX's numerous dependencies preinstalled to use these.

Thanks,

Lyle

OK, so you want to make sure that the new width and height are half of
the original width and height, e.g.

x, y = 0.5*@..., 0.5*@...
new_width, new_height = 0.5*@..., 0.5*@...
@image.crop(x, y, new_width, new_height, FXRGBA(236,233,216,255))

What "tutorial" are you referring to here?

I doubt there's a bug in the FXImage#rotate method, but yes, there
does seem to be a bug in the imageviewer.rb example program. I'll add
it to the bug list for future investigation.

I'm having trouble understanding exactly what is your question, but
looking at your code, I think you may have misinterpreted the
arguments for the FXImage#crop method. Here is the documentation:

http://www.fxruby.org/doc/api/classes/Fox/FXImage.html

The first two arguments to crop() are the (x, y) coordinates for the
top left corner of the crop rectangle, and the 3rd and 4th arguments
are the width and height. In your code, you call crop() like this:

@mywidth = 0.5*@...
@myheight = 0.5*@...
@image.crop(@mywidth, @myheight, @image.width, @image.height, FXRGBA
(236, 233, 215, 255))

So this says that it should start cropping in the middle of the
(original) image, but the resulting image should have the same height
and width as the original image. Can you maybe say what it is that you
expected to see, or what is your desired end result?

Hope this helps,

Lyle

howto generate an event action in code?

2009-10-17T05:08:56Z

In my search to try and solve my curent problem with the combobox pane being visible and having to put focus back onto another control how could I within a combo.connect(SEL_FOCUSIN) call get a SEL-CLICK event to fire?

my thinking here is that currently i need TWO clicks 1 for the closing of the dropped down pane and another to click on the dialogbox.
this so the other control (namely a textbox) gets the focus back.

cheers,

dave.

combox action issue

2009-10-17T04:23:34Z

Got a problem that i am unsure about how to tackle.

What I would like to have happen is this....

user move off a textbox and clicks on a combobox.
IF the textbox is empty then popup a dialogbox to alert the user of the error then return focus back to that control.

what I am getting is...

textbox empty user clicks on a combobox it's pane appears and then the dialogbox appears.
it is a two click action (1 to close the pane and 1 to close the dialogbox.
And the focus has not been returned to the textbox.

I've search the fxruby api docs for help but not getting much.

can someone point to a URL for more explainations on the SEL_ commands? as i think this will help me no end.

thanks,

Dave.

FXRuby on Gemcutter.org

2009-10-15T07:48:22Z

All,

It has come to my attention that there's a bot out there somewhere
that's downloading the FXRuby binary gems for Windows from
Gemcutter.org, and doing it a lot. It seems to be ignoring the source
gems, but it is mirroring every FXRuby Win32 gem that's ever been
published (even ones that are 5+ years old). This is artificially
inflating the "popularity" of FXRuby in Gemcutter's statistics, which
isn't helpful to anyone.

So, if this is you, please knock it off!

That is all. ;)

Thanks,

Lyle

I built a binary gem for FXRuby 1.6.19 on Leopard (back when I was running Leopard). It was compatible with the version of Ruby that shipped with Leopard.

Lyle, others,
I am having trouble getting fxruby going again. I used to have it running fine on Leopard. Then, I upgraded to Snow Leopard and also upgraded ruby... and broke everything... I am currently in dependency hell... see below.

Re: Dynamic creation of a tabbed book of tables

2009-10-10T10:13:51Z

No need to apologize! No one expects you to be on call to answer questions 24/7, or even at all if you don't want to!

Putting them in a hash was exactly what I had in mind, but it didn't seem to be working for me so I wasn't sure if it was possible. I'll have to experiment with that a bit more. As a workaround I've been doing the thing you dislike - removing (using each_child, remove_child) and recreating, rather than redrawing.

I guess what I need is to be able to use some sort of hash of the object ids for the individual tabs and tables created? ummm maybe using something like eachChildRecursive to nab the object ids?

Sorry for the delayed response, but I've been on vacation.

Technically, you can always "get to" these widgets by navigating through the widget hierarchy using methods like FXWindow#each_child, but that can be a little tricky. Why don't you just store them in arrays or hashes, e.g.

customs_summary_year_tabs = []
customs_summary_tables = []

years_on_file.each do |year|
customs_summary_year_tabs << FXTabItem.new(...)
...
customs_summary_year_tables << FXTable.new(...)
end

Hope this helps,

Re: FXDataTarget & widget value update delay

Wouldn't this be due to ruby 1.9.x using OS threads as apposed to software ("green") threads?

note: not used threads but am thinking i shall be needing them sooner than later for my project.

Re: Dynamic creation of a tabbed book of tables

Maybe just use instance_variable_set/instance_variable_get to set/get variables?

Re: Dynamic creation of a tabbed book of tables

Hmm, no, got that wrong, so this will create each of the tabbed tables, but the problem is that the instance variable names will be only associated with the last objects created, so there is no way to reference and update values in the earlier tables (without removing and recreating them of course).

I guess what I need is to be able to use some sort of hash of the object ids for the individual tabs and tables created? ummm maybe using something like eachChildRecursive to nab the object ids?

Hi all,

So I'm trying to create a bunch of tabbed tables in a tabbook, but I don't know in advance how many I will need, the number will depend on some data being read in by the system.

doing this:

        years_on_file.each do |year|
            @customs_summary_year_tab = FXTabItem.new(@customs_summary_tabbook, " #{year} ",
                :opts => TAB_TOP_NORMAL)
            @customs_summary_year_frame = FXHorizontalFrame.new(@customs_summary_tabbook,
                :opts => FRAME_THICK|FRAME_RAISED|FRAME_LINE)
            @customs_summary_table = FXTable.new(@customs_summary_year_frame,
                :opts => TABLE_COL_SIZABLE|TABLE_ROW_SIZABLE|LAYOUT_FILL|TABLE_READONLY)
            @customs_summary_table.setTableSize(num_of_rows, num_of_cols)
            @customs_summary_table.rowHeaderWidth = $row_col_frame_size
            @customs_summary_table.columnHeaderHeight = $row_col_frame_size

            ... more code that goes on to fill data into each table...

        end

will generate a number of tabs, but, of course, they all get filled with the identical data (that generated by the last iteration through the block). I'm thinking that myabe I need to somehow use some sort of dyanmic naming scheme for my tabs and tables, but I'm at a loss as to how to do that.

Any suggestions?

Thanks!

Re: no clean exit

2009-10-01T10:35:39Z

Hello,
I just thought about it and found a quick way of "solving" the
problem. I just pipe the errors to a file and look at the first rows
of that file:
ruby application.rb 2> err.txt; head -n 10 err.txt
Works for me. Thanks for the help anyway.

Björn Bergqvist

> While your program's running, if you (for example) destroy a parent object, FOX will subsequently destroy the child object(s), and the Ruby objects associated with them get cleaned up in an orderly fashion. When the Ruby interpreter is exiting, however, it is possible that the child object will be GC'd before the parent, leaving dangling pointers lying around. I'm not really sure how to fix it at this point.
