wxRuby + wxFormBuilder

okkezSS · October 12, 2010, 9:31pm

Hello. I have a problems. Can you help me?

I create GUI-program, based on wxWidgets, in wxFormBuilder.

1.jpg) I create a form in wxFormBuilder, it will see as left part of
image. If i test it on View->XRC WIndow, it see as the right part of
1.jpg. What is it?

2.jpg) I generated code and start compilize it. But it failed. Why?

Thanks in advance

Else one problem.

I create an application by Ctrl-C from one of lessons:

require ‘wx’
include Wx

class MyFrame < Frame
def initialize()
super(nil, -1, ‘My Frame Title’)
# First create the controls
@my_panel = Panel.new(self)
@my_label = StaticText.new(@my_panel, -1, ‘My Label Text’,
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
@my_textbox = TextCtrl.new(@my_panel, -1, ‘Default Textbox
Value’)
@my_combo = ComboBox.new(@my_panel, -1, ‘Default Combo Text’,
DEFAULT_POSITION, DEFAULT_SIZE, [‘Item 1’, ‘Item 2’, ‘Item 3’])
@my_button = Button.new(@my_panel, -1, ‘My Button Text’)
# Bind controls to functions
evt_button(@my_button.get_id()) { |event|
my_button_click(event)}
# Now do the layout
@my_panel_sizer = BoxSizer.new(VERTICAL)
@my_panel.set_sizer(@my_panel_sizer)
@my_panel_sizer.add(@my_label, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_textbox, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_combo, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_button, 0, GROW|ALL, 2)
show()
end

def my_button_click(event)
    # Your code here
end

end

class MyApp < App
def on_init
MyFrame.new
end
end

MyApp.new.main_loop()

I run it, but it window doesn’t open. In command prompt all work fint,
but doesn’t open. What’s matter?

1.jpg. What is it?

1.jpg) This is the cause of the fact that in your XRC Design, you do not
have a root Layout manager, meaning that the window needs to have a
VerticalSizer or a HorizontalSizer as the root item, in order to manage
layouts of all the controls in your window, otherwise, you have to do
the
management of the layout yourself, meaning you need to keep tabs on the
window sizes, and control positions, and re-positioning your controls
yourself. This also means that wxWidgets will not manage the window
size,
and therefore, will allocate the minimal size for your window, which
gives
you the issues you are seeing in 1.jpg.

2.jpg) I generated code and start compilize it. But it failed. Why?

This is an issue with Ruby 1.9.1, they made String where it is no longer
Enumerable, meaning that there is no .each method, that will parse
through
each actual line of text in the code, as is done in Ruby 1.8. I will
see
about getting a new gem built, with a patch to fix that soon.

Thanks in advance

Hello Misha,

First off, welcome to wxRuby community. I’ll answer your other question
in
a few, first we’ll cover this one.

First off, this is correct in the code, till you get to your on_init
method.
I can tell you, that your Window is being created, and everything, but
your
not showing it to the user. There’s two ways in which you can do this.

The first, is to simply do: MyFrame.new.show() Which will show your
frame
to the user, after it is created.
The second, is to store the instance of your Window in a variable, and
call
show in it, like this:
myframe = MyFrame.new
myframe.show

In both cases, you need to call the show method on your Frame, in order
to
have your frame actually be displayed. It isn’t done automatically,
cause
there may be times, where you want to create a window, but not show it,
in
such cases as having a Tray Icon on Windows / Linux, and a Dock Icon on
OS X
(EG The Bottom bar.)

hth with this one,

Mario

Thanks. Now I’m a new wx’er.

BTW, Misha on russian equivalent Michael in english

How you do the letters green?

I create forms now in DialogBlocks 4.39 (next - DB). If I do not
create a menubar, it’s OK. If I add it, I need to change a PLATFORM
value on it from any to some. It’s normal?
Conversion is normal in DB - in my opinion, the question is closed.
I copy code, but it not works:

require ‘wx’
include Wx

class MyFrame < Frame
def initialize()
super(nil, -1, ‘My Frame Title’)
# First create the controls
@my_panel = Panel.new(self)
@my_label = StaticText.new(@my_panel, -1, ‘My Label Text’,
DEFAULT_POSITION, DEFAULT_SIZE, ALIGN_CENTER)
@my_textbox = TextCtrl.new(@my_panel, -1, ‘Default Textbox
Value’)
@my_combo = ComboBox.new(@my_panel, -1, ‘Default Combo Text’,
DEFAULT_POSITION, DEFAULT_SIZE, [‘Item 1’, ‘Item 2’, ‘Item 3’])
@my_button = Button.new(@my_panel, -1, ‘My Button Text’)
# Bind controls to functions
evt_button(@my_button.get_id()) { |event|
my_button_click(event)}
# Now do the layout
@my_panel_sizer = BoxSizer.new(VERTICAL)
@my_panel.set_sizer(@my_panel_sizer)
@my_panel_sizer.add(@my_label, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_textbox, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_combo, 0, GROW|ALL, 2)
@my_panel_sizer.add(@my_button, 0, GROW|ALL, 2)
show()
end

def my_button_click(event)
    # Your code here
end

end

class MyApp < App
def on_init
MyFrame.new
end
end

MyApp.new.main_loop()

myframe = MyFrame.new.show()

There isn’t a .xrc file in this folder. It’s only .rb file. It doesn’t
work…

Can you give me some working simple window code to Copy-Paste in .rb
file as example of ruby-GUI-application.

Sorry for my english, Misha.

Into the installation of wxruby gem, you can find many examples to try
on.

bio.

Why everyone is silent?

rarstd · October 17, 2010, 7:16pm

This code:

#!/usr/bin/env ruby
require ‘rubygems’
require ‘wx’

class MyApp < Wx::App
def on_init
@frame = Wx::Frame.new( nil, -1, “Application” )
@frame.show
end
end

app = MyApp.new
app.main_loop
app.show

Doesn’t work. It show only command prompt with ruby, which close after
working code. I didn’t see GUI window. Why?

Maybe I don’t install something? What I must install to wxruby gui start
to work?

rarstd · October 17, 2010, 11:25pm

Piture is error message. This is testing of my application.

Run it in a command prompt and post the error message, then we can
help. There is a sample called ‘minimal.rb’ in the distribution that you
can use as a basis for testing and the starting point for your own apps.
