How the demo works:
|
|
|
|
Under the Draw menu, there are three options:
|
|
|
|
*Draw Test: will put up a picture of a bunch of randomly generated
|
|
objects, of each kind supported.
|
|
|
|
*Draw Map: will draw a map of the world. Be patient, it is a big map,
|
|
with a lot of data, and will take a while to load and draw (about 10 sec
|
|
on my 450Mhz PIII). Redraws take about 2 sec. This demonstrates how the
|
|
performance is not very good for large drawings.
|
|
|
|
*Clear: Clears the Canvas.
|
|
|
|
Once you have a picture drawn, you can zoom in and out and move about
|
|
the picture. There is a tool bar with three tools that can be
|
|
selected.
|
|
|
|
The magnifying glass with the plus is the zoom in tool. Once selected,
|
|
if you click the image, it will zoom in, centered on where you
|
|
clicked. If you click and drag the mouse, you will get a rubber band
|
|
box, and the image will zoom to fit that box when you release it.
|
|
|
|
The magnifying glass with the minus is the zoom out tool. Once selected,
|
|
if you click the image, it will zoom out, centered on where you
|
|
clicked. (note that this takes a while when you are looking at the map,
|
|
as it has a LOT of lines to be drawn. The image is double buffered, so
|
|
you don't see the drawing in progress)
|
|
|
|
The hand is the move tool. Once selected, if you click and drag on the
|
|
image, it will move so that the part you clicked on ends up where you
|
|
release the mouse. Nothing is changed while you are dragging. The
|
|
drawing is too slow for that.
|
|
|
|
I'd like the cursor to change as you change tools, but the stock
|
|
wxCursors didn't include anything I liked, so I stuck with the
|
|
pointer. Please let me know if you have any nice cursor images for me to
|
|
use.
|
|

Any bugs, comments, feedback, questions, and especially code are welcome:
