I wanted to enable custom shortcuts in my Firefox extension. The idea is that the user just focuses on a textbox, presses key combination, and it's shown in the textbox and saved to a preference. However, I couldn't get it to work. With this XUL
<?xml version="1.0"?>
<?xml-stylesheet href="chrome://global/skin/" type="text/css"?>
<?xml-stylesheet href="chrome://mozapps/skin/pref/pref.css" type="text/css"?>
<!DOCTYPE window SYSTEM "chrome://nextplease/locale/nextplease.dtd">
<prefwindow id="nextpleaseprefs" title="&options.title;" buttons="accept, cancel"
xmlns="http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul">
<prefpane id="nextplease.general" label="&options.general.title;" image="chrome://nextplease/skin/Sound Mixer.png">
<preferences>
<preference id="nextkey" name="nextplease.nextkey" type="int"/>
</preferences>
<vbox flex="1">
<hbox align="center">
<label value="&options.general.nextKey;" />
<textbox id="nextkey" flex="1" editable="false"
onkeyup="return nextplease.handleKeySelection(this, event);"
preference-editable="true" preference="nextkey"
onsynctopreference="alert('syncing'); return nextplease.syncKeySelector(this);"/>
</hbox>
</vbox>
</prefpane>
<script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseCommon.js" />
<script type="application/x-javascript" src="chrome://nextplease/content/nextpleaseOptions.js" />
</prefwindow>
the event in onkeyup works. But when I click the OK button, I don't see a "syncing" alert. Why isn't onsynctopreference working? Is it impossible to have custom onsynctopreference attribute for a textbox?
