I've made some significant progress on wxEditor, so I decided to push out a release. It works for the most part, and it's a good example of where the project is heading.

http://wxeditor.sourceforge.net/

Any and all feedback is welcome!

This is my very own control written from the ground-up in wxEuphoria. If you download the Win32 installer, it comes with the proper wxEuphoria dlls, so it should run straight out-of-the-box.

I too, spend 99% of my time in Linux. I only run Windows XP on VirtualBox when I absolutely need it. I've been developing this on my Windows box at work during my breaks and lunch hours, so development has been slower that I'd like.

wxEditor v0.1 works on Linux (no syntax highlighting) and v0.2 will work in Linux. I've done some modifying to the wxEuphoria C source code to get this to work properly, and I fear there may be even more. I've hit an issue where my wxSyntax control runs dog-ass-slow in Linux, but just fine in Windows. It must have something to do with how often I'm repainting the screen. I'll get that worked out in the next few days, hopefully. I just need to wrap a few more classes in wxEuphoria.

I think I may need to disable more Creole formatting. ++ means added text while -- means removed text. We probably do not need that type of formatting in a forum application. For document markup, it's great.

Yes, and no. I am using a modified version of wxEuphoria, but I have yet to commit my changes. I don't have SVN on my work computer. I'll get it setup and the changes committed asap. My modified add_create_func() and create() functions allow for Euphoria functions to be used for user-created controls. Essentially, you can pass a Euphoria routine_id() to add_create_func() via a sequence (instead of an atom) then create() makes a check for this and uses call_func() instead. It's pretty slick.

function new_wxSyntax( object params ) 
    return new_control_id 
end function 
 
global constant wxSyntax = add_create_func({ routine_id("new_wxSyntax") })

Interestingly, I had an opposite experience. On a ~3GHz, 4GB machine running XP, it was painfully slow (presumably, this was translated?). On my 1.6GHz Dual Core 1GB machine running Kubuntu, it seems fineinterpreted with eu4.0.

wxClientDC is in there. You use it just like any other DC.

I haven't looked at the code in much detail, but I suspect that the buffering isn't the issue. I basically copied the editor from Judith and ported it to wxeu, and it just stores everything in sequences. Memory usage can be high, and if there are many files loaded, there's a noticeable pause as memory swaps out, but it doesn't seem to affect the responsiveness otherwise.

It actually redraws the entire screen each keystroke, and blits everything to the window.

    -- redraw lines 
    bottom = length( text ) 
    if bottom - top > 100 then 
    	bottom = top + 100 
    end if 
    for line = top to bottom do 
        redraw_line( this, line ) 
    end for 

Okay, yeah... I think found it. In redraw_buffer() I have this:

    -- redraw lines 
 
    for line = top to length( text ) do 
 
        redraw_line( this, line ) 
 
    end for 
 

But I think it should be something like this:

    -- calculate number of lines to drawn 
    bottom = top + maxlines 
    if bottom > length( text ) then 
        bottom = length( text ) 
    end if 
 
    -- redraw lines 
 
    for line = top to bottom do 
 
        redraw_line( this, line ) 
 
    end for 
 

I haven't tried it, but I suspect that's it. I never really noticed because I was always loading small-ish files.

Good idea. I think I did that with some of my other attempts at text editors, because they used real controls to hold the text.
