Example program for Blox

Hello,

I tried to do myself a GUI application via Blox but couldn't achieve much. Is
there any example program written for Blox? I tried looking at the code of
Tetris and the code of class browser but dind't get much. A program which
consists of a simple window and button (doing something when pressed) would be
very helpful...

You can look at packages/blox/tests/test.st

It contains some functional tests to be used as

   BLOX.Gui test: #testName

where testName is one of

     callbackTest [
     canvasTest [
     dropdownTest [
     vContainerTest [
     hContainerTest [
     editTest [
     eventTest [
     formTest [
     formattingTest [
     textEventsTest [
     imageTest [
     labelTest [
     listboxTest [
     textTest [
     fileDialogTest [
     colorDialogTest [
     menuTest [
     popupMenuTest [
     iconTest [
     progressTest [
     colorButtonTest [
     balloonTest [

I looked at that but couldn't solve how to write the main loop which waits for
events to occur.

There is a loop like this in test.st:

[win exists] whileTrue: [(Delay forMilliseconds: 50) wait.

But it didn't behaved well while I was trying to create a simple window. Is
there a more elegant way like:

Tk().mainloop()

in Python?

It also gives an error like:

test.st:3: key Gui not found

while trying to run. I didn't try it on Linux though.

A simple script which creates a window and a button in it which closes the
window when pressed at the button would be much appreciated :) Then I would be
able to find out most other things by investigating the class browser.

No, that loop is just in the progress bar test, to modify the progress
bar every 50 ms.  The event loop is

         BLOX.Blox dispatchEvents: win

(see Gui class>>#test:)

Just load it with

        PackageLoader fileInPackage: 'Blox'

and go around in the class browser.
