Hi,
I''m trying to get to grips with a Ruby GUI and have plunked for Fox
and/or FoxGUIb. I''m having problems at the moment trying to do
something simple which I can''t find in the samples or tutorials how to
do. Basically, in my main window, its composed of 2 vertical frames. There is a
menu at the top for all the options. All Im trying to do is display text inputs
fields in the left vertical frame.This is for user input, to run specific apps.
What text fields shown are dependant on the menu option chosen. The right frame
is a response screen.Below is some snippets:-
..... My left vertical frame for data input.....
@group1 = FXGroupBox.new(contents, "Information",
:opts =>
GROUPBOX_TITLE_LEFT|FRAME_RIDGE|LAYOUT_FIX_WIDTH|LAYOUT_FIX_HEIGHT,
:width => 200, :height => 400)
...... My menu option.......
mymenu = FXMenuPane.new(self)
FXMenuTitle.new(menubar, "&Target", nil, mymenu, LAYOUT_LEFT)
details=FXMenuCommand.new(mymenu,
"&Details").connect(SEL_COMMAND) do
FXTextField.new(@group1, 10, :opts =>
FRAME_SUNKEN|FRAME_THICK|LAYOUT_FILL_X)
end
What I thought should have happend in the above snippet was that on selecting
the ''mymenu'' option, a new text field would be entered into
the vertical frame ''@group1''. However this doesnt happen.
Nothing happens.
Ideally, I''d like the command on selecting the menu option to go to a
function that changes the look of the vertical frame i.e, showing different text
fields dependant on the menu chosen. Im sure its a syntex issue.
Can you point me to an example on how this can be done?
Thanks,

However this doesnt happen. > Nothing happens.You need to add a call to create() for the dynamically created text fields, e.g. details = FXMenuCommand.new(...) details.connect(SEL_COMMAND) do textfield = FXTextField.new(@group1, ...) textfield.create @group1.recalc end The create() creates the server-side resources (windows) for the newly constructed widgets, and calling recalc() on the group box marks its layout as dirty.> Ideally, I''d like the command on selecting the menu option to go to > a function that changes the look of the vertical frame i.e, showing > different text fields dependant on the menu chosen.

You can just call a function from inside the connect() block, e.g. details.connect(SEL_COMMAND) { update_groupbox_contents } and then, somewhere else: def update_groupbox_contents textfield = FXTextField.new(@group1, ...) textfield.create @group1.recalc end Hope this helps, Lyle

But that doesn''t help you in the short term. The best resources, for now, are the documentation at the FOX web site (http://www.fox-toolkit.org/) and the FXRuby web site (http://www.fxruby.org/). There''s also some coverage of FXRuby in Hal Fulton''s book The Ruby Way (2nd ed.), which is a good book to have in general if you''re doing Ruby work. -------------- next part -------------- An HTML attachment was scrubbed...
