Time for action – scroll bars

1. In the Toolbox window, double-click on the VScrollBar control to add it to the form. Give it the following properties:

   1. Name : vScrollBar1

   2. Anchor : Top, Bottom, Right

   3. LargeChange : 48

   4. Location : 658, 27

   5. Size : 17, 576

2. In the Toolbox window, double-click on the HScrollBar control to add it to the form. Give it the following properties:

   1. Name : hScrollBar1

   2. Anchor : Bottom, Left, Right

   3. LargeChange : 48

   4. Location : 184, 606

   5. Size : 474, 17

3. Add the FixScrollBarScales() helper method to the MapEditor class:

   private void FixScrollBarScales()
   {
       Camera.ViewPortWidth = pctSurface.Width;
       Camera.ViewPortHeight = pctSurface.Height;
   
       Camera.Move(Vector2.Zero);
   
       vScrollBar1.Minimum = 0;
       vScrollBar1.Maximum =
           Camera.WorldRectangle.Height -
           Camera.ViewPortHeight;
   
       hScrollBar1.Minimum = 0;
       hScrollBar1.Maximum = 
           Camera.WorldRectangle.Width -
           Camera.ViewPortWidth;
   }

4. Edit the MapEditor_Load() method to include a call to FixScrollBarScales...
