1. /IUP/ Help needed with examples

I have a page of "predefined dialogs" in the wiki: http://openeuphoria.org/wiki/view/Predefined%20Dialogs.wc

Working Examples History

1. ( ok ) IupAlarm
2. ( ok ) IupColorDlg
3. ( ok ) IupElementPropertiesDialog
4. ( partial ) IupFileDlg
5. ( ? return value ) IupFontDlg
6. ( ok ) IupGetColor
7. ( ? what is arq ) IupGetFile
8. ( not decoded ) IupGetParam
9. ( ? second argument ) IupGetText
10. ( ok ) IupLayoutDialog
11. ( not decoded ) IupListDialog
12. ( ok ) IupMessage
13. ( ok ) IupMessageDlg
14. ( incomplete ) IupProgressDlg

As you can see I can't get example programs to work with all dialogs. Some are just plain messy and for others I can't figure out the data-types.

These two dialogs are the basis of a "poor man's" ide:

1. IupLayoutDialog
2. IupElementPropertiesDialog

If you have time, please help

thanks

I proposed modifications to IupGetParam here:

http://openeuphoria.org/forum/m/129127.wc

Greg seemed to agree with this proposal but I didn't notice any change in existing code some weeks ago.

I don't know why it is called arq: it should be filename. Here is what IUP documentation writes:

filename: This parameter is used as an input value to define the default filter and directory. Example: "../docs/*.txt". As an output value, it is used to contain the filename entered by the user.

I am working through the Iup examples and also "A Basic Guide to using IupLua" (see http://www.luteus.biz/Download/LoriotPro_Doc/LUA/LUA_For_Windows/iup/iup.html)

I am trying a version of the Alert example:

-- Example 2 
-- Alarm 
 
include gui/iup/iup.e 
 
constant reply = {"File saved sucessfully - leaving program", 
			"File not saved - leaving program anyway", 
			"Operation cancelled"} 
 
procedure main( sequence cmd = command_line() ) 
	IupOpen( 0, {} ) 
	integer b = IupAlarm("IupAlarm Example", "File not saved! Save it now?" ,"Yes" ,"No" ,"Cancel") 
	-- Shows a message for each selected button 
	printf(1, "The response is: %s", {reply[b]}) 
	if getc(0) then end if 
	IupMessage("Save File", reply[b]) 
	IupClose() 
end procedure 
 
main() 

Lines 14 & 15 are added to prove that b is correctly returned; why doesn't the IupMessage get invoked?

I found the same issue when "translating" the "Asking for Multiline Text" example (IupGetText usage) from Lua to Eu; same solution works there.

Thanks for the help. I'll keep going on those examples. Do you want me to post them anywhere once they work?

I think that if we are to make the EuIup library seem as easy and Euphoric as possible then IupGetFile has to have a sequence argument, to avoid expecting the user to invoke both allocate_string and poke_string; likewise IupGetText needs two sequence arguments for the same reason.

PS Can you think why neither the Lua nor the C examples need this "blank" dialog. Is it something in the (Eu) Iup library? (I didn't have to do anything like this when using Jeremy's library in the past.)

-- Example 2 
-- Alarm 
 
include gui/iup/iup.e 
 
constant reply = {"File saved sucessfully - leaving program", 
			"File not saved - leaving program anyway", 
			"Operation cancelled"} 
 
procedure main( sequence cmd = command_line() ) 
	IupOpen( 0, {} ) 
	integer b = IupAlarm("IupAlarm Example", "File not saved! Save it now?" ,"Yes" ,"No" ,"Cancel") 
	-- Shows a message for each selected button 
	printf(1, "The response is: %s", {reply[b]}) 
	if getc(0) then end if 
	IupMessage("Save File", reply[b]) 
	IupClose() 
end procedure 
 
main() 

Try this:

include iup/iup.e 
 
constant reply = {   
                    "File saved sucessfully - leaving program",  -- 1 
                    "File not saved - leaving program anyway",   -- 2 
                    "Operation cancelled"                        -- 3 
                 }  
 
IupOpen(NULL) 
 
integer b = IupAlarm( "IupAlarm Example", "File not saved! Save it now?", "Yes", "No", "Cancel" ) 
 
? b   -- 1 | 2 | 3 
 
IupMessage( "Hello Message", reply[b] ) 
 
 
IupClose() 

I can't explain, but I always remove lines of code until a program works.

Hi

these are the examples from the IUP side: They work

http://webserver2.tecgraf.puc-rio.br/iup/examples/Lua/message.lua

-- IupMessage Example in IupLua  
-- Shows a dialog with the message: “Click the button”.  
 
require( "iuplua" ) 
 
iup.Message ("IupMessage", "Press the button") 

http://webserver2.tecgraf.puc-rio.br/iup/examples/C/message.c

/* IupMessage Example */ 
 
#include <stdlib.h> 
#include <stdio.h> 
 
/* IUP libraries include */ 
#include <iup.h> 
 
/* Main program */ 
int main(int argc, char **argv) 
{ 
  /* Initializes IUP */ 
  IupOpen(&argc, &argv); 
   
  /* Executes IupMessage */ 
  IupMessage("IupMessage Example", "Press the button"); 
 
  /* Finishes IUP */ 
  IupClose (); 
 
  /* Program finished successfully */ 
  return EXIT_SUCCESS; 
 
} 

Looking at http://webserver2.tecgraf.puc-rio.br/iup/en/dlg/iupmessage.html

IupMessage seemd to use PARENTDIALOG (even if it is not needed).

Maybe, (i say only maybe) if IupAlarm sets PARENTDIALOG and dies than IupMessage may use an invalid handle as parent and may die.

Just an idea.
