1321 How the demo works:
1322
1323 Under the Draw menu, there are three options:
1324
1325 *Draw Test: will put up a picture of a bunch of randomly generated
1326 objects, of each kind supported.
1327
1328 *Draw Map: will draw a map of the world. Be patient, it is a big map,
1329 with a lot of data, and will take a while to load and draw (about 10 sec
1330 on my 450Mhz PIII). Redraws take about 2 sec. This demonstrates how the
1331 performance is not very good for large drawings.
1332
1333 *Clear: Clears the Canvas.
1334
1335 Once you have a picture drawn, you can zoom in and out and move about
1336 the picture. There is a tool bar with three tools that can be
1337 selected.
1338
1339 The magnifying glass with the plus is the zoom in tool. Once selected,
1340 if you click the image, it will zoom in, centered on where you
1341 clicked. If you click and drag the mouse, you will get a rubber band
1342 box, and the image will zoom to fit that box when you release it.
1343
1344 The magnifying glass with the minus is the zoom out tool. Once selected,
1345 if you click the image, it will zoom out, centered on where you
1346 clicked. (note that this takes a while when you are looking at the map,
1347 as it has a LOT of lines to be drawn. The image is double buffered, so
1348 you don't see the drawing in progress)
1349
1350 The hand is the move tool. Once selected, if you click and drag on the
1351 image, it will move so that the part you clicked on ends up where you
1352 release the mouse. Nothing is changed while you are dragging. The
1353 drawing is too slow for that.
1354
1355 I'd like the cursor to change as you change tools, but the stock
1356 wxCursors didn't include anything I liked, so I stuck with the
1357 pointer. Please let me know if you have any nice cursor images for me to
1358 use.
