FXRuby ComboBox problems:

ruby-talk
1

First problem: The empty alternative shows just about two pixels in
height.
""
"male"
"female"
How can I get the full height?

Second problem: The leftmost characters in the combo has a lighter
background color. The number of characters seem to equal the shortest
string
" " # shortest string
"male" # m has lighter background
"female" # f has lighter background
How can I get the correct background color everywhere in the combo?

These are minor problems, but disturbing.
I really love the speed and the API of FX, so I'm not ready to switch
yet.

some code:

    # Win XP, FXRuby 1.4.3
    width = 10
    cbo = FXComboBox.new(@parent, width, nil, 0, COMBOBOX_STATIC)
    cbo.appendItem(" ",0)
    cbo.appendItem("female",1)
    cbo.appendItem("male",2)

easiest way is to put a space inside instead of an empty string.
annother way would be setting the layout to LAYOUT_FIX_HEIGHT.

strange feature isn't it? don't know when the combobox became like
this. anyway here is the trick that removes the selection of the text:
cbo.children[0].killSelection

hth,

I tried the advice, but failed to see any improvement.
LAYOUT_FIX_HEIGHT did not work, and cbo.children[0] refers FXWindow,
not FXTextField, where killSelection is defined.

I must have found a weak spot of FXRuby. The combobox is used for
selecting a string in 90% of all cases. The default behaviour of
FXComboBox is text editing and substring selection.

I've tried to find the source code, but failed.

hmm, sorry. but, i have tried it in FXRuby1.4.4 and i actually got an
FXTextField!
i also checked out the height thing: the height of the combo is always
the same for me ... only the item with the empty string in the list is
very small.
