Custom Text Edit Control

Hi All,

I've been writing a custom text edit control as a replacement for the standard one. It's not as hard as I imagined it would be.

If you have the time could you test out the text area and see if anything stands out as being broken.

You can download it here

The code for the demo (minus the actual text edit gadget code:

Strict
Framework brl.GLMax2D
Import brl.Win32MaxGUI
Import brl.Retro
Import brl.FreeTypeFont
Import brl.Timer
Include "EditControl.bmx"

SetGraphicsDriver GLMax2DDriver()
Local Edit:TEditControl

Local Window:TGadget = CreateWindow("Text Edit Control 0.7",20,20,512,512,Null,WINDOW_TITLEBAR | WINDOW_RESIZABLE | WINDOW_STATUS)
Local w=ClientWidth(Window)
Local h=ClientHeight(Window)

Edit = New TEditControl.Create(Window,0,0,w,h)

Local Infile:TStream 
InFile = ReadFile("History120.txt")
Local Ed:String
	While Eof(InFile) = False 
		ed = ReadString(infile,FileSize("History120.txt"))
	Wend
CloseFile Infile
edit.SetString ed
While True
	WaitEvent
	If EventSource() = Window and EventID() = EVENT_WINDOWCLOSE Then End
Wend

Does this use any Win32 specific code, besides the gui module? I'm just
wondering if this can be used on Mac and Linux too.

yeah, I've been doing the same thing... competition is always healthy I guess.

No Win32 jiggery pokery, it's just a canvas with text display code, so it should work just as well on all platforms I suppose.



I'd be interested in trying a demo of your one when you've done! :)

I've been messing with this one for a couple of days and so far I'm happy with how it's turning out.

Once I'm finished, I'll be releasing the code for all to play with and improve.

ToDO:
Scrollbars, Colors, Formatting, Tidy up interface code..

Looks great!
Dont forget syntax colors and clipboard support :D

^+1

This seems to be fast code (tm)!

sure, I could upload one tomorrow. I'm a little further along then you are right now, per your demo anyway.

Sounds good. It'll be nice to have something to aspire to.

here is the demo...
copy and paste are in but right now they are mapped to f1 and f2. I incbined MS's consola font so if you get the default then, that didn't work.

there are some bugs... the biggest is x cursor positioning offscreen is not right. the other is there is a slow down when changing the scroll position at first but it goes away after drawing about 2 screens. the included file is over 3300 lines... I've tested it on files over 30,000 and the performance (on my machine at least is still the same)

oh yeah.... the folding is not complete yet... (I don't fobid the editing of the title line)

Hi Dmaz,

Thanks for that. There are some issues I found. If you change your location with the mouse scroll wheel then move the cursor with the arrow keys, then it redraws the wrong stuff on screen.

Highlighting also goes a bit screwy at times and it doesn't delete chunks you have highlighted.

It's much better than my one on other areas though (scroll bars for instance) and folding etc.

Thanks for the demo, it will be interesting to see how they both develop.

that's odd, that didn't do that until just recently, darn! [edit]yeah that was a last minute change with a dumb oversight on my part, now fixed[/edit]


yeah, I haven't spent much time on that yet.

thanks for the feedback... Have you made any more progress?

Not much. I put the scrollbars in, but there is a chunk of 'Hack like' code in there for checking the bounds of the on screen text which I'm not too happy with, so I'll want to change that before I do another test.
