Is it true that the stock FXCanvas doesn't support tooltips, but we can 
get around that with a subclass of FXCanvas:

	require 'fox'
	require 'fox/responder'

	include Fox

	class TooltipCanvas < FXCanvas

	  include Responder

	  attr_accessor :tipText

	  def initialize(*args)
	    # Initialize base class
	    super

	    # Default tooltip
	    self.tipText = "Canvas"

	    # Listen for query messages from the tooltip
	    FXMAPFUNC(SEL_UPDATE, FXWindow::ID_QUERY_TIP, :onQueryTip)
	  end

	  def onQueryTip(sender, sel, ptr)
	    sender.text = tipText
	    return 1
	  end
	end

You should be able to use this one in place of a normal canvas, and set 
its tooltip message with the tipText accessor.

Hope this helps,

Lyle

Yes, if you can send me a simple test case for this one, please do.

Yes, I still have this test case and run it before each release ;) It 
is the "stress1.rb" case, under the FXRuby tests directory.

How many iterations did it take for this one to crash on your machine? 
I ask because I'm running it right now (with my development version of 
FXRuby) and so far it's gotten to "count=1800" without crashing. I will 
go back and build FXRuby-1.0.28 from the earlier sources, but I'm 
fairly sure I ran this test before releasing that version too.

[Fxruby-users] Segfaults

[Gilles F. <gil...@fr...>]

Hi Lyle,

It's been long time since I've tried FXRuby intensively :o)
I'm back with the same kind of segfaults I had then.

For example FXEvent appears corrupted after a while in an onPaint 
callback. I don't have a simple test case yet. I'll try to narrow the 
probelm using valgrind. The bug vanishes when GC is disabled.

Just to try, I've launched an old test case (not related to the above 
bug) I used when there were problems with TreeList items. Segfault 
again. I send it to you by private mail.

My box runs :
- Debian/sarge GNU/Linux
- fox-1.0.42
- ruby 1.8
- FXRuby 1.0.28
HTH.

_gilles.

No, you are correct that there's no way to get a handle on the current 
redo command. Jeroen has addressed this problem in the FOX 1.2 version 
of FXUndoList, so in the interest of (future) API compatibility, I 
think I'll add two new methods:

* FXUndoList#undoName returns the text of the current undo command (or 
nil if there is none)
* FXUndoList#redoName returns the same for the current redo command.

How does that sound?

Re: [Fxruby-users] Multi-colored FXList

[Riccardo G. <ric...@fi...>]

Hi

well, with Marco Frailis we have done in Ruby a ColredListItem that 
works following the fifthplanet answer of Lyle .. the main difference 
(and problem) with respect to the C++ solution was that it is not 
sufficient to have a ColoredListItem inheriting from an FXListItem and 
implementing a different draw method .. it seems that the Ruby wrapper 
of FXList use always the method draw of the superclass (in this case 
FXListItem) when it paints the widget .. our solution was to define a 
new ColoredList inheiritng from a FXList and reimplement just the 
onPaint method of this class (just coping and Ruby adapting from the C++ 
method onPaint of the Fox) ..

in that case it calls the draw method of the ColoredListItem .. this 
solve our problem, but probably is not an elegant solution .. moreover 
we need also a ColoredTreeList and it is much more complicate to 
reimplement the onPaint method of the FXTreeList .. Lyle, do you know of 
a better (and easier) way to obtain that?

Hmm .. reading back the email probably is not so clear .. if someone is 
interested let me know and I'll send the code ..

Bye, Riccardo :)

[Fxruby-users] Listview using FXTable

[Jamey C. <jc...@tw...>]

Although I have been using FXIconList as a listview in my applications, 
it is missing a few things like column justification and gridlines.  So, 
I started playing around with FXTable to see if I could get it to work 
as a listview.

I have pretty much gotten it working like I would want.  Here are the 
advantages/disadvantages I have noticed between using FXTable or 
FXIconList as a listview widget:

FXTable
---------
Advantages:
* Gridlines
* Column justification
* Looks nicer (IMO)
* Can specify custom column header arrow.

Disadvantages:
* Lose column resizing (I know FXTable has column resizing, but I had to 
turn it off to get the rest of my sample app to work right.)
* You have to do your listview sorting outside of the listview, instead 
of letting the widget handle it.

Anyway, I have include a sample program that demonstrates how it looks.  
Give it a try.  If you figure out a better way to do something in the 
program, please let me know.

Thanks.

[Fxruby-users] Tooltips

[Daniel S. <da...@pr...>]

Is it possible to add Tooltips to an FXCanvas?

I gather that the way if I wanted to do so, I'd be connecting to a
ID_QUERY_TIP message and then doing something in response to that.
However, ID_QUERY_TIP never seems to be fired.=20

Or possibly I'm meant to be connecting to a SEL_UPDATE and ID_QUERY_TIP
is the selector? (I'm not sure I'm understanding what selectors are all
about).

Am I looking in the right place?

This is all I can find on the topic:

[Fxruby-users] Connecting multiple listeners to an object

[Daniel S. <da...@pr...>]

I've been frustrated with the fact that you can't connect multiple
things to an FXObject. Ie.

=09target =3D FXDataTarget.new()
=09target.connect(SEL_COMMAND) { puts "hello" }
=09target.connect(SEL_COMMAND) { puts "hello2" }

The only thing that gets printed when the target is changed is "hello2".


How do others normally deal with this? Do you have your code such that
all connectors must go through in intermediary? Do you only connect in
the one place?

I've thrown together a module to include in classes that I want to
multi-connect to.=20

module MultiConnect
=20 def self.append_features(mod)
=20   mod.module_eval {
=20     alias_method :connect_orig, :connect
=20     private :connect_orig
=20   }
=20   super

[Fxruby-users] Building FXRuby against a DEV copy of FOX

[Marc C. <ma...@is...>]

Jeroen van der Zijp recently made a few changes to the FOX library that
are necessary to the completion of a project I'm working on. However the
changes are only reflected in the dev. snapshot of FOX, and are not yet labeled
'stable'. I've recently found out that FXRuby, as is, refuses to build against
anything but a 'stable' copy of the FOX library. Is there any way to convince
the installer that I don't care if it's built on a dev. copy of FOX?

I have FOX-1.1.49 built, the developement copy, and I tried building 
FXRuby-1.0.28 against that.

There isn't a straightforward way to do this in FOX 1.0. You could 
conceivably do it by subclassing FXTableItem and overriding its 
drawContent() method, but that is much more problematic than it should 
be. Hopefully, Jeroen will address some of these limitations in FOX 1.2.

Subject: [Fxruby-users] Setting individual cell color with
FXTableItem::drawBackground( )?


I've recently begun working a bit with FXRuby. While messing around with

the code for Tables, I found out that I cannot set individual cell 
colors with FXTable::setCellColor . Now, looking at the API I noticed 
that FXTableItem has an instance method called drawBackground, with the 
parameters table, dc, x, y, w, h. I am assuming that dc is a FXDC 
object, table the parent table of the FXTableItem in question, x and y 
coordinated in pixels, and w and h width and height in pixels. So I 
figured that I could possibly set individual cell color with something 
along the lines of
    @table.getItem( row, col ).drawBackground( @table, dc, x, y, w, h )
However, my attempts so far have been in vain. I've attempted to get x, 
y, w, and h by using
    @table.getColumnX( col ),
    @table.getRowY( row ),
    @table.getItem( row, col ).getWidth( @table ), and
    @table.getItem( row, col ).getHeight( @table ) respectively. I
wasn't sure what to use for dc, so I created a new FXDC 
by using
    dc = FXDC.new( self )
(which didn't work if I recall correctly). So my question is, is it even

possible to use FXTableItem.drawBackground or am I on a futile quest? If

it is possible, what should I use for dc?

[Fxruby-users] Workable hyperlink on FXDialogBox screen

[John R. <col...@ya...>]

I’m trying to put a workable hyperlink on my FXDialogBox screen, and I’m wondering if anyone else has done something like this without using something like MS Word.

 

Thanks,

Try forceRefresh.

Though I've had some frustration with that occasionally too.

1. Given an FXTreeList wherein I add or change an item, how do I get the
tree to redisplay?

2. Given an MDIClient where I add or resize an MDIChild, how do I get it
to display?

3. Given an MDIChild with a textbox inside it, can I click on the window
frame and select the window without giving focus to the textbox?


#1 and #2 are obviously variations on a theme. I've tried various
permutations of create, show, repaint, recalc, refresh and one or two
others.

Is there a method called just_show_me_the_damned_widget ?

Re: [Fxruby-users] FXMenuCommands as options

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

Although they don't use datatargets its a similar concept. The MenuCommand 
sends a SEL_UPDATE to its target, in this case the table and the table 
responds by sending a message back to the sender (the menucommand) to either 
check or uncheck himself.

[Fxruby-users] FXMenuCommands as options

[Daniel S. <da...@pr...>]

I've been looking at the code for the sample program table.rbw, and the
following section is confusing me:

=20   # Options Menu
=20   tablemenu =3D FXMenuPane.new(self)
=20   FXMenuCommand.new(tablemenu, "Horizontal grid", nil,
=20     @table, FXTable::ID_HORZ_GRID)
=20   FXMenuCommand.new(tablemenu, "Vertical grid", nil,
=20     @table, FXTable::ID_VERT_GRID)
=20   FXMenuTitle.new(menubar, "&Options", nil, tablemenu)

This creates the Options menu pane, and creates two buttons in it that
send the "ID_HORZ_GRID" and "ID_VERT_GRID" events to @table when they
are clicked.=20

When the application is run, these two menu items have check-boxes next
to them. What is making these checkboxes appear? There's no events with
the menu items as targets. There's no calls to the "check" method. How
does this hang together?

[Fxruby-users] Thanks & more questions :)

[Hal F. <ha...@hy...>]

Thanks, Lyle and others, for your assistance.

The reward for answering questions is always the same...
you get to answer more.  ;)

I didn't know a widget could be "deaf" to events (although
experimentation had convinced me that this one was).

Anyone as clumsy with Fox as I am may find this function
as useful as I have:

   def snag(obj,msg)   # for debugging
     obj.connect(eval(msg)) { puts "#{obj.class} object got #{msg}" }
   end


My next question is:

Given an MDIClient, how can I redisplay its contents after I
resize a child or add a new child?

I've tried various combinations of repaint and refresh and recalc
and show and whatnot.


Thanks,
Hal

I want to redesign the menubar when I click on icons, but all I got is
nasty error message. Is there a way to do what I want?

Re: [Fxruby-users] Sorting a FXTable

[Lyle J. <ly...@kn...>]

Well, yes, but it's getting those from Ruby's Enumerable module. 
FXTable, like some other widgets, mixes-in Enumerable. Since FXTable's 
each() method is aliased to FXTable#each_row, I guess that FXTable#sort 
is going to return a sorted array of table rows, where each table row 
is represented by an array of cells. It's questionable how useful that 
is ;)

There's no FXTable equivalent for the sortItems() method. I think 
you'll have to roll your own on this one, possibly making use of the 
results returned by sort().

Hmmm. Try this:

*	Make sure that the MDI client widget is enabled (i.e. it's not "deaf" 
to events)
	by calling its enable() method after you create it.

*	Add a handler on the MDI client for the SEL_LEFTBUTTONRELEASE
	(or SEL_LEFTBUTTONPRESS, if you prefer) and do the killFocus() in
	that one.

Let me know how it goes,

Lyle
