Hi.

I have the following code in my application (www.insula.cz/dbtalk/):

# Handle interrupt to save stuff nicely
application.addSignal('SIGINT', window, DbTalkWindow::ID_QUIT)

# Create the windows
application.create

# Open the connection dialog automatically
window.handle(window, MKUINT(DbTalkWindow::ID_OPENCONNECTION, SEL_COMMAND), nil)

# Start event loop
application.run


This worked perfectly in FXRuby 1.0.20 but it crashes in 1.0.24 on the line 
with window.handle. It is used for automatical opening of a dialog window after 
the application starts-up.

Is this a possible bug or did I use the feature incorrectly all the time before?

Thanks

Dalibor Sramek

Hello all,
 
I am trying to do something simple (I think) but it is not working for
me. I when the button is pressed to put another button below the first
button and so on until the entire frame scrolls. Below is my code. 
 
Thanks for the help in advance

Right after the line that constructs the new button:

     v = FXButton.new(@contentFrame, "Button #{i}")

you want to first add a line to create (or "realize") the button:

     v.create

and then tell the vertical frame to recalculate its layout:

     @contentFrame.recalc

Hope this helps,

Lyle

Hi all.

I'm trying to use Fox to make a chat program. I want
to have a list that displayes messages as they come
in. Unfortunately, I'm having trouble getting the
FXList to scroll down. Using makeItemVisible doesn't
seem to do the trick, and neither does anything else
I've tried (setCurrentItem, updateItem, etc). The
following script shows the problem by periodically
inserting data into a FXText and a FXList, and
attempting to scroll to the bottom of each. Works for
the text, but not the list. Can anyone help me out?


#~/usr/bin/ruby

require 'fox'

app = Fox::FXApp.new()
mainwin = Fox::FXMainWindow.new( app,
  "FoxTest", NIL,NIL,
  Fox::DECOR_ALL,128,128,128,64 )
frame = Fox::FXHorizontalFrame.new( mainwin,
                              Fox::LAYOUT_FILL_X|
                              Fox::LAYOUT_FILL_Y )
list = Fox::FXList.new( frame, 0, NIL, 0,
                  Fox::LIST_NORMAL|
                  Fox::LAYOUT_FILL_X|
                  Fox::LAYOUT_FILL_Y,
                  0,0,64,64 )
textbox = Fox::FXText.new( frame, NIL, 0,
                     Fox::TEXT_READONLY|
                     Fox::LAYOUT_FILL_X|
                     Fox::LAYOUT_FILL_Y )

app.create()
mainwin.show()
Thread.abort_on_exception = TRUE
Thread.new do
  listendpos = 0
  textendpos = 0
  while TRUE
    listendpos = list.appendItem(
       "foonly #{listendpos}" )
    list.makeItemVisible( listendpos )

    textbox.appendText( "foonly #{textendpos}\n" )
    textendpos = textbox.lineEnd(
      textbox.getBottomLine() )
    textbox.makePositionVisible( textendpos )

    sleep(1)
  end
end
app.run()

Your code is OK; I think this is a bug in FXRuby. As a workaround, 
please see what happens if you replace this line:

     window.handle(window,
       MKUINT(DbTalkWindow::ID_OPENCONNECTION, SEL_COMMAND), nil)

with this:

     window.onOpenConnection(nil, nil, nil)

If that takes care of it, I think I know what the problem is...
