Hi

I making a little program and in that program i need to grab a piece of thw screen with my mouse.

I need to grab a rect by dragging the mouse, and maybe resize the rect.

I have tried but with no luck.
I can draw a rect with my mouse but can't resize it.

Anyone have some sample code to draw/resize a rect on screen with the mouse?

Thanx in avance!

You'll probably need to use something like CopyRect....I'm not sure, though. Check the help file for stuff on buffers and copyrect.

Here you go:

Graphics 640,480,0,2
SetBuffer BackBuffer()

x=0
y=0
width=0
height=0

;a main loop
While Not KeyHit(1)

	;if the user clicks
	If MouseHit(1)
	
		;first coords
		x=MouseX()
		y=MouseY()
		
		;keep doing this while the user holds the mouse down
		While MouseDown(1)
			width = MouseX()-x
			height = MouseY()-y

			Cls
			Rect x,y,width,height,1			
			
			Flip
		Wend
		
	EndIf
	
Wend
End
