Map Editor nearing completion

The mapeditor is nearing it's completion. It was quite fun to develop, and it's a bit of a shame I'm almost done with it.

There are some radical changes in it, such as that I stepped of the DirectInput mouse. At my first attempt, I attempted to initialize DirectInput for the mouse, and use that to handle the input. Problem was: I had to make up a fancy way to detect wether or not the mouse exited from the rendering area and unacquire(). In the end, it turned out the mouse was moving faster in Windows than it was under DirectInput(strange?), so I stepped off the DInput mouse.

I know process the MouseEnter, MouseLeft, MouseMove and MouseClick events off the panel where Direct3D renders in. Then I call a class member function of the TileBrush to set the new position of the square. When the mouse leaves or enters the area, I either make the square visible or invisible, so the little square doesn't sit at the corners doing nothing. This is how it looked liked:

That's quite sexy eh? This screenshot also shows the TileBrush in action. The TileBrush class is responsible for drawing tiles into the map, and to check if it needs to draw some extra tiles. For instanece, if I want to draw a Spice Dune(The dark area in the screenshot), it has to be in the middle of a spice field. To accomplish this, I first check if all 8 tiles surrounding the tile are of the required tile type. If not, I set them, and after that, I finally add the tile itself.

It's funky, but not completely flawless. I can still place those tiles, and replace all the spice with sand. My next entry contains how I solved it.

When I made the brush work, I wanted to go to bed. I just had to implement scrollbars, and make them work. Scrolling is simple: The horizontal scrollbar has a maxvalue of map.Width - map.ViewPortSize.Width, and the same for the vertical scrollbar. When the bars are scrolled, I can then just set the viewport positions. Simple, yet very effective. This is the final result:


Now I only need to work out an algorythm to round of the edges of the tiles(so they don't look all squary), remove certain tiles if they're not surrounded by their required tile, show some map information, make a "New Map" dialog and loading/saving.
