Peter – I cut and paste your code to try in AIR to trigger a state change – it successfully changes from initial state to isMouseInSWF state but does not change back on exit. Any ideas?

thanks, Max

It should be

systemManager.stage.addEventListener(Event.MOUSE_LEAVE, stage_mouseLeave);

Hello Everyone,

I have ran into issues with using this. For example, the mouse leave event is dispatched when a context menu is displayed via right click. So, if you are in the center of the stage and right click, the mouse leaves the stage. So, I modified this example by adding a “mouse border” around the stage and I check to see if the mouse is within the border before it leaves the stage.

I hope that this helps….
var mouseOutOnX:Boolean = ( mouseX (stage.width – 10));
var mouseOutOnY:Boolean = ( mouseY (stage.height – 10));
if ( ( mouseOutOnX || mouseOutOnY) )
{
…….

Likewise, it seems that this is limited if you alt+tab to a different window while your mouse is done. It seems as though since the browser is no longer the active window when the mouse up occurs it can’t detect it and therefore no MOUSE_LEAVE event is dispatched.

A similar error to the one Kristian documented happens if you have ‘wmode’ set to ‘transparent’, if you leave the stage with the mouse pressed and release outside the event won’t fire, then when you enter the stage again the slider thumb is stuck to the mouse, and when you release you get an error.

wmode set to transparent has 20+ errors associated with it, avoid it at all costs :) (it’s sometimes unavoidable)

Hi Peter.

I’ve logged the bug under the Flash Player, as it also happens with Flash CS3, so it’s not limited to Flex.

Bug number is FP-733.

Cheers,
Kristian.

Kristian,

Can you please file a bug at http://bugs.adobe.com/flex/ and include a simple test case, if possible. That may be a bug with the Flex Slider control or possibly Flash Player.

Peter

Great example, but it does have limitations.

When adding a slider, if you hold the slider thumb down then keep the mouse button pressed and move off the stage, it fires when you release the mouse button.

However, if the swf is in a table, and you do the same, the event never fires!

I’ve noticed that when you interact with the browser outside the flash movie, that funkiness happens inside the movie.

e.g. Highlight the view source line
