Hi list
I have build a small application, like it is shown in the
header.rb example.
But I want do change the amount of the child of the
FXHorizontalFrame.
This child are FXList's. I want to remove some of this list
while the
program is running.
That for I iterate through the FXHorizontalFrame and calls
.destroy for
each one.
Look at the function : clearAll
But it seems not working.
Can any one of you say me the best way of solving my
problem?

code:
----
class HeaderList < FXScrollWindow
attr_reader :colors, :lists, :header
def initialize(parent, opts=0, x=0, y=0, width=0,
height=0)#,
padLeft=DEFAULT_SPACING, padRight=DEFAULT_SPACING,
padTop=DEFAULT_SPACING, padBottom=DEFAULT_SPACING,
hSpacing=DEFAULT_SPACING, vSpacing=DEFAULT_SPACING)
super(parent,opts|SCROLLERS_NORMAL,x,y,width,height)#,padLef
t,padRight,padTop,padBottom,hSpacing,vSpacing)
 lists = []
packer=FXPacker.new(self,LAYOUT_FILL_X|LAYOUT_FILL_Y,
0,0,0,0,
0,0,0,0, 0,0)
header = FXHeader.new(packer,nil,0,HEADER_RESIZE)
header.connect(SEL_CHANGED) { |sender, sel, which|
lists[which].width = header.getItemSize(which)
}
content = FXHorizontalFrame.new(packer,
LAYOUT_FILL_X|LAYOUT_FILL_Y,0,0,0,0, 0,0,0,0, 0,0)
colors=[FXRGB(255,240,240),FXRGB(240,255,240),FXRGB(2
40, 240, 255)]
actC = 0
end
def addRow(text,icon=nil,size=0,data=nil,notify=false)
item = FXHeaderItem.new(text,icon,size,data)
header.appendItem(item,notify)
(size == 0)? (siz = item.getWidth(header)) : (siz = size)
list = FXList.new(content,nil,0,
LAYOUT_FILL_Y|LAYOUT_FIX_WIDTH,0,0,siz,0)
list.backColor = colors[actC]
actC = (actC+1)%colors.length()
lists.push(list)
end
def
appendItemTo(index,text,icon=nil,data=nil,notify=false)
lists[index].appendItem(text,icon,data,notify)
end
def clearAll()
header.clearItems()
lists.clear()
content.each_child{|list|
list.destroy
}
#content.destroy
puts content.numChildren
end
end
