[MAXGUI] How to make a "Voting Box"?

This whole method stuff is new to me.

	Method Hide()
    	HideGadget (canvas)
        hidden=True 
    End Method 

    Method Show()
        ShowGadget (canvas) 
        hidden=False 
    End Method 

	Method update()
		Local t:Int
		Local mini:Int
		Local gh:Int=GadgetHeight(canvas)

            If hidden=False Then ' Unitbar hidden completely?

		    SetGraphics CanvasGraphics(canvas)
			SetClsColor 0,0,0;Cls
            
            If disabled=False Then ' Draw an enabled Unitbar only
 
            SetColor 100,100,100 
			For t=value To units
				DrawRect (number*12)+t*unitwidth+1,1,unitwidth-2,gh-1-1
			Next
						
			For t=1 To value
				SetColor r[t],g[t],b[t]
				DrawRect (number*12)+t*unitwidth+1,1,unitwidth-2,gh-1-1
			Next

			SetColor 255,255,255
			DrawText value,number*12/2-TextWidth(value)/2,gh/2-TextHeight(value)/2

            Else ' Draw an empty Unitbar

            SetColor 100,100,100 
			For t=1 To units
				DrawRect (number*12)+t*unitwidth+1,1,unitwidth-2,gh-1-1
			Next
					
			value=0 				
			SetColor 255,255,255
			DrawText value,number*12/2-TextWidth(value)/2,gh/2-TextHeight(value)/2

            EndIf ' Disabled

            EndIf ' Hidden
			Flip
	End Method

Better this way?!?^^

This canvas stuff drives me crazy. Why can't one simply resize it. Is it a bug or has it to be that way? 1.18
