    <p>I'm creating a jQTouch app in PhoneGap for the iPhone. I've been battling with this issue for days. I've seen the eventlistener solution suggested a few times, but just could not get it to work.</p> <p>In the end I came up with a different solution. It basically checks the width of the body periodically using settimeout. If the width is 320 then the orientation is portrait, if 480 then landscape. Then, if the orientation has changed since the last check, it will fire either a portrait stuff function or a landscape stuff function where you can do your thing for each orientation.</p> <p>Code (note, I know there is some repetition in the code, just haven't bothered to trim it down yet!):</p> <pre><code>// get original orientation based on body width deviceWidth = $('body').width(); if (deviceWidth == 320) { currentOrientation = "portrait"; } else if (deviceWidth == 480) { currentOrientation = "landscape"; } // fire a function that checks the orientation every x milliseconds setInterval(checkOrientation, 500); // check orientation function checkOrientation() { deviceWidth = $('body').width(); if (deviceWidth == '320') { newOrientation = "portrait"; } else if (deviceWidth == '480') { newOrientation = "landscape"; } // if orientation changed since last check, fire either the portrait or landscape function if (newOrientation != currentOrientation) { if (newOrientation == "portrait") { changedToPortrait(); } else if (newOrientation == "landscape") { changedToLandscape(); } currentOrientation = newOrientation; } } // landscape stuff function changedToLandscape() { alert('Orientation has changed to Landscape!'); } // portrait stuff function changedToPortrait() { alert('Orientation has changed to Portrait!'); } </code></pre>

    2. CO1) You should use `onresize` event that will fire immediately, not in 500 miliseconds 2) This code is android-specific, use `onorientationchange` instead for iPhone 3) Test if it's supported in the browser: `"onorientationchange" in window`

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
