[Flashcoders] Yahoo Maps: Detecting latitude and longitude of mouse over map
Hi I'm trying to detect the latitude and longitude of the cursor as the user moves their mouse around a map. Should be straightforward I thought - if I use LatLonRect data and then calculate based on _xmouse and _ymouse data and the height and width of the movieClip containing the map, I should be able to do this right? Weird problem is that flash reports the _height and _width of the movieclip incorrectly. I have a movieClip mapTable_mc in which there is a map named map The actual dimensions of the movieClip (and also the map) are 400 X 300 pixels. trace(mapTable_mc._height) …output is 1280 trace(mapTable_mc._width) …output is 1280 Trace mapTable_mc.map._height …output is 1280 Trace mapTable_mc.map._width …output is 1280 Height and width are not only incorrect but also the same as each other! If I trace _xmouse and _ymouse values, they are exacly as expected. Can anyone shed any light?

The actual dimensions of the movieClip (and also the map) are 400 X 300 pixels. Sorry, that was a typo - they are actually 500 X 400 pixels.

When flash calculates _width and _height, it also includes things inside the movieclip which may be invisible, or masked out. Try this simple example: On the stage, create an empty movie clip A which contains two square movieclips B and C, which are placed next to each other This code will produce the same output 4 times: trace(A._width); A.B._visible = false; trace(A._width); A.C._visible = false; trace(A._width); A._visible = false; trace(A._width); Not sure if this is related exactly to your problem, but I've had issues with _width _height before, and this is usually the cause. -David R On 7/20/06, Dave Wood [EMAIL PROTECTED] wrote: The actual dimensions of the movieClip (and also the map) are 400 X 300 pixels.

Hi David When flash calculates _width and _height, it also includes things inside the movieclip which may be invisible, or masked out. Good thought, but no, the movieclip contains nothing beyond the area covered by the map instance. Note that it wsan't just the clip containing the map the gave the strange values, but also of the map itself.
