Hi!

I am not active with the pkg for two years now.
I found it pretty good. I stopped the project where I was using it, openmindmap.sf.net, because I couldn't find collaborators and I had no fun in working alone.

Ciao,

I found what was wrong. Use the following code.

I'm trying to update the TextDisplay widget to include the textfont,

static FN_GETSET_INT(Text_Display,textfont);

Everything compiles correctly, but when I try to use any of the methods I
get a segfault.  I'm using the 0.9.0 source and mingw and gcc 3.2.1

Hi Takaaki,

I moved the "notice the hposition changed" to the browser handle method
and the redraw then starts to work.

Don't understand why its different but I'm pleased to have the problem
fixed!

Hi Takaaki,

My problem isn't with the handling of horizontal scroll in the browser_
itself - that works fine and automatically.

The problem is that I have a second widget that also needs to be redrawn
if the browser's horizontal scroll changes.  The 2nd widget is a heading
line, also allowing dragging of columns and column widths.  If the browser
is scrolled across then I need to draw the heading line similarly
scrolled.

I took your test script and expanded it to illustrate my problem.  In my
test I want the "Hposition is .." at the bottom to be redrawn whenever the
browser scroll changes.  I detect the change in the browser correctly ,
but calling footer.redraw and nothing happens.

OTOH, if you hide and re-show the window the "Hposition" footer will be
correctly redrawn.

Steve

I don't exactly understand your trouble.
After you call Browser_#has_scrollbar(Browser_::BOTH), a scrollbar is
automatically added if the item_widths exceed the width of browser.
Of course, the browser can be automatically scrolled if you scroll the
scrollbar. So I think you don't need to redraw.

I checked with the following scripts.

PS. Browser_::BOTH is not defined in Ruby/FLTK. Use `3' instead of it.

require 'fltk'

class MyBrowser < Fltk::Browser_
  include Fltk::Drawable

  def initialize(x,y,w,h,args)
    super(x,y,w,h)
    @selected_items = {}
    @items = args.collect{|arg| arg.to_s}
  end

  def handle(e)
    case e
    when FLTK::PUSH
      item = find_item(FLTK::event_y())
      bx,by,bw,bh = bbox()
      if( item && (FLTK::event_x() < bx + bw) && (FLTK::event_y() < by + bh) )
	select(item,true)
	return true
      end
    end
    return super(e)
  end

  def item_next(obj)
    @items[@items.index(obj) + 1]
  end

  def item_prev(obj)
    idx = @items.index(obj)
    if( idx > 0 )
      @items[idx - 1]
    else
      nil
    end
  end

  def item_first()
    @items[0]
  end

  def item_draw(obj, x, y, w, h)
    color(textcolor())
    text_draw(obj, x, y + bbox()[1])
  end

  def item_height(obj)
    15
  end

  def item_width(obj)
    text_width(obj)
  end

  def full_height
    p :full_height
    super
  end

  def full_width
    p :full_width
    super
  end

  def item_select(item, s)
    @selected_items[item] = true
  end

  def item_selected(item)
    p @selected_items
    @selected_items[item]
  end
end

items = ["one", "two-----------long....", "three", "four", "five", "six", "seven", "eight"]

w = Fltk::Window.new(0,0,100,120,"Label"){|w|
  b = MyBrowser.new(5,5,90,90,items)
  b.textcolor = FLTK::RED

[ruby-fltk-users] In draw for 1 widget, setting another widget for redraw?

[Stephen D. <st...@da...>]

Takaaki or others,

I'm having redraw pain - perhaps you can help?

I have a Browser_ subclass that I'm using to show a multi-column SQL
result set.

I have also created a Box subclass that I'm using as a heading line placed
on top of the Browser_ subclass.

Now Browser_ automatically adds a horizontal scrollbar if the item_widths
exceed the size of the browser.  The user can now scroll the browser
left-right.

I want to get the header widget to redraw when the browser is scrolled -
my draw routine uses the hposition from the browser to draw the heading
correctly aligned.

Unfortunately, I can't get the heading to redraw at the right time.

FLTK has the horizontal scrollbar callback use hposition to scroll the
browser.  Unfortunately, that hposition method isn't virtual so I can't
intercept it in ruby in order to also scroll the heading.

So my second idea was to detect the change in hposition in my Browser_
item_draw.  This detection works OK.

But: when I notice the hposition change I call the heading's redraw.

At which point nothing happens.

I suppose this has something to do with the fact that I call the heading's
redraw out of the browser_'s draw.  But I can't figure out why or what the
connection is...

Any ideas or suggestions?

Thanks,
Steve Davies

Maybe FLTK::SYMBOL_LABEL is useful for such purpose.
If you set it for the label type using Widget#labeltype,
you can write symbols including an arrow by writing "@->",
"@>" and so on. For example:

  w = FLTK::Window.new(200,200){
    l = FLTK::Box.new(0,0,100,100)
    l.labeltype(FLTK::SYMBOL_LABEL)
    l.label("@> arrow")
  }
  w.show
  FLTK::run

Looks like its hardcoded in fltk itself, though this could be tweaked I
guess.

Hi Takaaki,

Thanks for the pointer and the example.

It isn't my first choice to have an actual screen widget - I'm looking to
construct and pop-up a custom menu from my custom widget's handle method.

Is there a way to have the MenuButton widget created but not actually
mapped on the window?  And then just use menubutton.popup when I want to
show it?

I will tinker some on my own and see what I come up with.

Once only slightly connected question - is there a way to make the arrows
for sub-menus a little more subtle?

Thanks,
Steve

Use FLTK::MenuButton with the type POPUP3. Here is an example:

require 'fltk'

$items1 = [
  ["item1", 0, proc{ print("item1\n") }, "item1_data", FLTK::SUBMENU],

  ["item2", 0, proc{ print("item2\n") }, "item2_data", FLTK::SUBMENU],
    ["foo", 0, proc{ print("item2/foo\n") }, "item2_foo_data"],
    [],
  ["item3", 0, proc{ print("item3\n") }, "item3_data", FLTK::SUBMENU],
    ["foo", 0, proc{ print("item3/foo\n") }, "item3_foo_data"],
    [],
]

FLTK::Window.new(300,100){|win|
  mb = FLTK::MenuButton.new(0,0,100,100,"popup")
  mb.menu($items1)
  mb.widget_type(FLTK::MenuButton::POPUP3)

[ruby-fltk-users] Ruby/FLTK v0.8.3

[Takaaki T. <tt...@kt...>]

Hello,

I released ruby-fltk-0.8.3 today. Binary packages of this release
have not been released yet. Those will be available later.

Here are changes in 0.8.3:

0.8.2 -> 0.8.3 (Fri Sep  6 08:25:31 UTC 2002)
---------------------------------------------
* Added Tooltip module. (for fltk-1.1.0rc4)

* Fixed Widget#damage(), it should return a damage mask.

* Fixed Menu_#add().  When it takes one argument and a block,
  the block was never called.

* Added FileChooser#new_button, preview_button (for fltk-1.1.0rc5).

* Added ToggleButton classes.

* Added CheckBrowser class (for fltk-1.1.x).

* Added Progress class (for fltk-1.1.x).

* Got rid of FLTK::Thread, since we will be able to use Ruby's Thread
  with structured exception handling of Windows.

* Added FN_GETSET_UINT and FN_GLOBAL_GETSET_UINT, and fixed some 32bit
  color operations. (Thanks Stephen Davies)


I appreciate your suggestions and bug reports. However, my reply will
be delayed, since I don't have enough time for Ruby/FLTK now.
