Detecting Flash for Charts

[pete_walsh]

I'd like to detect whether or not the user has Flash installed (for using Charts) and if not, give them a link to download flash. What would be the best way to do this in GXT?

Chart extends FlashComponent which has a setExpressInstall function. It seem like if I give it the location of expressInstall.swf it should work, but I've had no success when Flash isn't installed at all.

Any help on this would be really appreciated

It seems like express install is supposed to work only if some version of Flash is already installed - it just upgrades it.

I have been annoyed by this for a while and decided to find a solution. Simply override the onAttach method of the Chart class so that it puts a download link in chart div. If flash is not available the div doesn't get replaced by swfobject.js and the download link is visible.


@Override
protected void onAttach() {
super.onAttach();
el().setInnerHtml("<div id=\"" + getSwfId() + "\"><h1>Charts require Flash Plugin</h1><p><a href='http://www.adobe.com/go/getflashplayer'><img src='http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif' alt='Get Adobe Flash player' /></a></p></div>");
SwfConfig config = new SwfConfig();
injectFlash(config);
}

Thanks a lot. It works great.
