wxruby users - Jun 2009 - TextCtrl text alignment

As shown in the attached program, the text "My Long Textbox Value "in
the TextCtrl object, @my_textbox, aligns off the screen in Windos XP (32
bit, SP3)

Any help with this would be appreciated.

Thanks,

Nick G.

I see what you mean - even if only the TextCtrl is present (it always 
helps to reduce your example to as simple as possible to isolate the 
problem).

I think this is just a ''feature'' of the underlying Windows
toolkit - it
always selects the first widget in a new frame when it''s shown, and
when
selecting a TextCtrl, selects all the text in there. Why it scrolls a 
bit horizontally I don''t know. But you could mitigate this by calling

text_ctrl.set_selection_point(0)
text_ctrl.set_selection_point_end

after the call to show()

btw, a couple of things you can write more tersely in wxRuby code:

@my_label = StaticText.new(@my_panel, -1, ''My Label Text'', 
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
# better as:
@my_label = StaticText.new(@my_panel, :label => ''My Label
Text'', :style
=> ALIGN_CENTRE)

evt_button(@my_button.get_id()) { |event| my_button_click(event)}
# better as:
evt_button @my_button, :my_button_click

Well, that is helpful, although I think perhaps you meant:
set_INSERTION_point(0), not "set_selection_point".  :)
BUT point(0), point(1), point(2), point(3), point(4) all produce the 
same good outcome - the text aligned exactly flush with the left margin, 
while "set_insertion_point(5)" reproduces the original problem in
which
the text is scrolled to the left and the first characters that appear 
are "ong" from "Long..."  I note that the comboBox is text
is perfectly
aligned, exactly one space from the far left margin.
You did solve the problem, for which I am grateful, but do you know why 
set_insertion_point is behaving like this?  Is it because in the 
underlying Windows toolkit the earlier insertion points ((i) with i<5) 
prevent the horizontal scrolling, but a later insertion point permits 
it?  I suppose so.
How odd!
Thanks again,
Nick
