BlitzMapper Help Topic

Well as some know I'm trying to make a map editor for 2D games, and with my lack of experience my ideas are a bit limited, and I need your help to complete this project.
So if you have time to spare then help me~

Ok so far I made a rather limited thing but I got no idea how to do the rest, and thats where you come in.
(note: Source is at the bottom.)

I got a pretty basic menu set up,
as you can see at the bottom I used Blitz+ GUI thing.

So how would I go if I want that when you click on NEW
it would creates a Temp .map file (txt file)
and create this:

------------
| |        |
| |        |
------------

First little box would have a Load button to load a Tile file, 32x32 with a gride and the other side would show your map...?

You guys following me?

It might be alot to ask from you nice peoples but it would help me a great deal to have this program when it finished and it would help me learn alot.

WinHandle=CreateWindow("Blitz Mapper",0,20,640,480)

menu=WindowMenu(WinHandle)

; MENU
file=CreateMenu("File",0,menu)
CreateMenu "New",1,file
CreateMenu "Load",2,file
CreateMenu "Quit",3,file

layers=CreateMenu("Layers",0,menu)
CreateMenu "Add Layer",4,layers
CreateMenu "",5,layers
CreateMenu "Layer 1",6,layers
DisableMenu layers

UpdateWindowMenu WinHandle


Repeat

	; Wait for an event to occur...
	id=WaitEvent()
	
	; exit on a window close event
	If ID=$803 Then End 

	; handle a menu event
	If ID=$1001 Then
		EID=EventData()
		Select EID

        Case 1
            Notify "You have selected, NEW"

        Case 2
            Notify "You have selected, Load"

        Case 3
            End

        End Select
	End If


Forever
End

NO MAPPY please.

My idea right now is to created 2 canvas gadget 4 scroll bar X,Y for each canvas and make a button onto fo the first canvas to load tile image, is this a good idea, your opinion please (<-doesnt know what hes doing)

Fine I understand no one wants to help me.
I guess I'll just give it my best.

sorry, i'm not familliar with the gui side of b+...
